This is a Billingo API v3 documentation. Our API based on REST software architectural style. API has resource-oriented URLs, accepts JSON-encoded request bodies and returns JSON-encoded responses. To use this API you have to generate a new API key on our site. After that, you can test your API key on this page.

API Interface to retrieve company data and products from business registers

UPDATE: We have released a beta version of the new bunq API documentation.
NOTICE: We have updated the sandbox base url to https://public-api.sandbox.bunq.com/v1/. Please update your applications accordingly. Check here: for more info.
PSD2 NOTICE: The second Payment Services Directive (PSD2) may affect your current or planned usage of our public API, as some of the API services are now subject to a permit. Please be aware that using our public API without the required PSD2 permit is at your own risk and take notice of our updated API Terms and Conditions on for more information.
Introduction
Welcome to bunq!
The bunq API is organised around REST. JSON will be returned in almost all responses from the API, including errors but excluding binary (image) files.
Please configure your implementation to send its API requests to https://public-api.sandbox.bunq.com/v1/
There is a version of the Android app that connects to the bunq Sandbox environment. To create accounts for the Sandbox app, please follow the steps in the Android Emulator section.
Getting started
Before you start sending API requests, you need to get an API key and activate it. API activation happens when you install the API key and link your IP address and device to it (create an API context). The steps below will guide you through what you need to do to start sending custom API requests.
Here is an overview of what you can use to get started with the bunq API:
Create an API key. You can do it either in our developer portal or in the bunq app (Profile → Security & Settings → Developers → API keys). If you want to test our sandbox first, our bunq Developer is the best place to start.
Register a device. A device can be a phone (private), computer or a server (public). You can register a new device by using the POST /installation and POST /device-server calls. This will activate your API key. You only need to do this once.
Open a session. Sessions are temporary and expire after the auto-logout time set for the user account. It can be changed by the account owner in the bunq app.
Make your first call!
bunqAPIcontext
Versioning
Developments in the financial sector, changing regulatory regimes and new feature requests require us to be flexible. This means we can iterate quickly to improve the API and related tooling. Therefore, we have chosen not to attach any version numbers to the changes just yet.
We will inform you in a timely manner of any important changes we make before they are deployed on together.bunq.com. You can also subscribe to our API newsletter to make sure you don't miss any important updates.
OAuth
What is OAuth?
OAuth 2.0 is a protocol that will let your app connect to bunq users in a safe and easy way. Please be aware that if you will gain access to the account information of other bunq users or initiate a payment for them, you may require a PSD2 permit.
Get started with OAuth for bunq
To initiate authorization into the bunq user accounts, you need to create an OAuth Client and register at least 1 redirect URL for it.
You can have 1 OAuth Client at a time. Reuse your OAuth credentials for every authorization request.
The list of steps below will help you to get started:
Register an OAuth Client by creating an app in bunq Developer.
Add one or more Redirect URLs.
Get your client_id and secret from your app information tab in bunq Developer.
Redirect your users to the OAuth authorization request URL.
If the user accepts the authorization request, they will be redirected to the previously specified redirect_uri with an authorization code parameter.
Use the token endpoint to exchange the authorization code for an access_token.
Use the access_token as a normal API Key. Open a session or use our SDKs to get started.
You can set up an OAuth Client and add redirect URLs to it using the dedicated endpoints too. Follow the flow below to do it programmatically.
ℹ️ As a PSD2 user, you cannot log in to the bunq app. You need to follow the flow below to register an OAuth Client for your application.
bunqOAuthcredentials
What can my apps do with OAuth?
We decided to launch OAuth with a default permission that allows you to perform the following actions:
read and create Monetary Accounts;
read Payments & Transactions;
create Payments between Monetary Accounts of the same user;
create Draft-Payments (the user will need to approve the payment using the bunq app);
assign a Monetary account to a Card;
read, create and manage Cards;
read and create Request-Inquiries
read Request-Responses.
As a PSD2-licensed developer, you are limited to the permission scopes of your role.
Authorization request
Your web or mobile app should redirect users to the following URL:
https://oauth.bunq.com/auth
The following parameters should be passed:
response_type - bunq supports the authorization code grant, provide code as parameter (required)
client_id - your Client ID, get it from the bunq app (required)
redirect_uri - the URL you wish the user to be redirected after the authorization, make sure you register the Redirect URL in the bunq app (required)
state - a unique string to be passed back upon completion (optional)
Use https://oauth.sandbox.bunq.com/auth in the sandbox environment.
Authorization request example:
Android Emulator
In case you do not own an Android device on which you can run our Sandbox app for end-to-end testing, you can set up an emulator to run the bunq Sandbox app for Android.
Things you will need
The bunq Sandbox App APK that's optimised for emulating;
Android Studio.
Starting the Android Virtual Device (AVD) Manager
Open Android Studio.
From the top menu, select “Tools” > "Android" > "AVD Manager".
Setting up a new virtual device
Start the wizard by clicking on "+ Create Virtual Device".
Select a device (recommendation: "Pixel 5.0" or "Nexus 6") and press "Next".
Select an x86 system image (recommendation: Nougat, API Level 25, Android 7.1.1 with Google APIs) and press "Next". The image needs to have Google Play Services 10.0.1 or higher.
In the bottom left corner, select "Show Advanced Settings".
Scroll to "Memory and Storage".
Change "Internal Storage" to "2048 MB".
Change "SD card" to "200 MB".
Press "Finish".
Starting the virtual device
On the right side under "Actions", select the green "Play" button.
Wait for the device to boot, this may take a few minutes.
Installing the bunq Sandbox App APK
Open the command line.
Navigate to your Android SDK platform tools directory (e.g. cd ~/Library/Android/sdk/platform-tools on macOS).
Make sure that the virtual device is started and has fully booted.
Run ./adb install ~/Downloads/bunq-android-sandboxEmulator-public-api.apk, this may take a few minutes, and should finish with "Success".
Creating an account or logging in
Create a sandbox account in the developer portal.
Log in to the sandbox app using the sandbox user credentials.
ℹ️ You will be asked to verify your phone number when you open the app for the first time. Sandbox does not send actual SMS messages. Enter any valid phone number and use the default verification code 992266.
If you couldn't generate a sandbox account in the developer portal, use Tinker:
Install Tinker.
Run tinker/user-overview to create a sandbox account. The output of the command will include the login credentials for the sandbox account.
⚠️ NOTE: It is not possible to create accounts using the regular signup in the app, bunq is not reviewing Sandbox applications.
Moving to Production
Have you tested your bunq integration to the fullest and are you now ready to introduce it to the world? Then the time has come to move it to a production environment!
To get started you'll need some fresh API keys for the production environment, which you can create via your bunq app. You can create these under "Profile" by tapping the "Security" menu. We do, however, highly recommend using a standard API Key instead of a Wildcard API Key. The former is significantly safer and it protects you from intrusions and possible attacks.
There's only a few things to do before your beautiful bunq creation can be moved to production. You're going to have to change your API Key and redo the sequence of calls to open a session.
The bunq Public API production environment is hosted at https://api.bunq.com.
Do you have any questions or remarks about the process, or do you simply want to show off with your awesome creations? Don't hesitate to drop us a line on together.bunq.com.
Please be aware that if you will gain access to account information of other bunq users or initiate a payment for them, you maybrequire a PSD2 permit.
Quickstart: Opening a Session
Goal
So, you want to start using the bunq API, awesome! To do this, you have to open a session in which you will be making those calls.
Getting an API key
To connect to the API, you have to make sure you have received an API key.
For production:
create an app in the developer portal, or
generate it in the bunq app (Profile → Security & Settings → Developers → API keys).
For sandbox
You can use one of the following ways:
create a sandbox user in the developer portal;
generate an API key in the sandbox app (Profile → Security & Settings → Developers → API keys);
get an API key from Tinker;
run a cURL request: curl https://public-api.sandbox.bunq.com/v1/sandbox-user-person -X POST --header "Content-Type: application/json" --header "Cache-Control: none" --header "User-Agent: curl-request" --header "X-Bunq-Client-Request-Id: $(date)randomId" --header "X-Bunq-Language: nlNL" --header "X-Bunq-Region: nlNL" --header "X-Bunq-Geolocation: 0 0 0 0 000". Use sandbox-user-company to generate a business user.
Note that production API key is only usable on production and sandbox key is only usable on sandbox. Sandbox key has a sandbox_ prefix while production key does not have any noticeable prefixes.
Call sequence
The calls you need to perform to set up a session from scratch are the following:
1. POST installation
Each call needs to be signed with your own private key. An Installation is used to tell the server about the public key of your key pair. The server uses this key to verify your subsequent calls.
Start by generating a 2048-bit RSA key pair. You can find examples by looking at the source code of the sdk's located at github.
Headers
On the headers page you can find out about the mandatory headers. Take care that if you are in the sandbox environment, you set an Authorization header. Specific to the POST /installation call, you shouldn't use the X-Bunq-Client-Authentication or the X-Bunq-Client-Signature headers.
Body
Post your public key to the Installation endpoint (use \n for newlines in your public key).
Response
Save the Installation token and the bunq API's public key from the response. This token is used in the Authentication header to register a DeviceServer and to start a SessionServer. The bunq API's public key should be used to verify future responses received from the bunq API.
2. POST device-server
Further calls made to the server need to come from a registered device. POST /device-server registers your current device and the IP address(es) it uses to connect to the bunq API.
Headers
Use the token you received from POST /installation in the X-Bunq-Client-Authentication header. Make sure you sign your call, passing the call signature in X-Bunq-Client-Signature header.
Body
For the secret, use the API key you received. If you want to create another API key, you can do so in the bunq sandbox app (or production app for the production environment). Login, go to Profile > Security and tap 'API keys'. The freshly created API key can be assigned to one or multiple IP addresses using POST device-server within 4 hours before becoming invalid. As soon as you start using your API key, it will remain valid until the next sandbox reset. For the secret, use the API key you received.
3. POST session-server
To make any calls besides installation and device-server, you need to open a session.
Headers
Use the token you received from POST /installation in the X-Bunq-Client-Authentication header. Make sure you sign your call, passing the call signature in X-Bunq-Client-Signature header.
Body
For the secret, use the API key you received.
Response
The token received in the response to POST /session-server should be used to authenticate your calls in this session. Pass this session's token in the X-Bunq-Client-Authentication header on every call you make in this session.
Quickstart: Payment Request
Goal
You want to offer bunq payments on a website or in an application.
Scenario
In this use case the consumer and the merchant both have a bunq account. The consumer wants to pay with bunq and enters their alias in the bunq payment field at checkout. The merchant sends the request for payment to the consumer when the consumer presses enter. The consumer agrees to the request in the bunq mobile app and the merchant has immediate confirmation of the payment. Please be aware that if you will gain access to account information of other bunq users or initiate a payment for them, you require a PSD2 permit.
Before you start
Make sure that you have opened a session and that for any call you make after that, you pass the session’s token in the X-Bunq-Client-Authentication header.
Call Sequence
The consumer is at checkout and selects the bunq payment method. This would be a logical time to open a session on the bunq server.
1. LIST monetary-account
When a request for payment is accepted, the money will be deposited on the bank account the request for payment is connected to. Let’s start by finding all your available bank accounts. Pick one of them to make the request for payment with and save its id.
2. POST monetary-account attachment (optional)
Optionally, you can attach an image to the request for payment.
Headers
Make sure you set the Content-Type header to match the MIME type of the image. It’s also required you pass a description of the image via the X-Bunq-Attachment-Description header.
Body
The payload of this request is the binary representation of the image file. Do not use any JSON formatting.
Response
Save the id of the posted attachment. You’ll need it to attach it to the request for payment.
3. POST request-inquiry
Next, create a request inquiry. A request inquiry is the request for payment that your customer can respond to by accepting or rejecting it.
Body
Pass the customer’s email address, phone number or IBAN in the counterpartyalias. Make sure you set the correct type for the alias, depending on what you pass. When providing an IBAN, a name of the counterpartyalias is required. You can provide the id of the created attachment.
Response
You will receive the id of the created request inquiry in the response. Save this id. You will need it to check if the customer has responded to the request yet.
4. GET request-inquiry
After you’ve sent the request for payment, its status can be checked.
Response
When the status is ACCEPTED, the customer has accepted and paid the request, and you will have received the money on the connected monetary account. If the status is REJECTED, the customer did not accept the request.
Quickstart: Create a Tab payment
Goal
You will create a tab that can be paid once by a single user, a so called TagUsageSingle, and explore three different ways to make the Tab visible to your customers:
QR code from the CashRegister
QR code from the Tab.
Before you start
Make sure that you have opened a session and that for any call you make after that, you pass the session’s token in the X-Bunq-Client-Authentication header.
Call sequence
1. POST attachment-public
Start by creating an attachment that will be used for the avatar for the cash register.
Header
Make sure you set the Content-Type header to match the MIME type of the image. It is also required you pass a description of the image via the X-Bunq-Attachment-Description header.
Body
The payload of this request is the binary representation of the image file. Do not use any JSON formatting.
Response
Save the uuid of the posted attachment. You'll need it to create the avatar in the next step.
2. POST avatar
Make an avatar using the public attachment you've just created.
Body
The payload of this request is the uuid of the attachment public.
Response
In response, you’ll receive the UUID of the avatar created using the attachment. Save this UUID. You’ll use it as the avatar for the cash register you're about to create.
3. LIST monetary-account
Get a listing of all available monetary accounts. Choose one, and save the id of the monetary account you want your cash register to be connected to. Each paid tab for the cash register will transfer the money to this account.
4a. POST cash-register
Create a cash register. Use the id of the monetary account you want to connect the cash register to in the URL of the request.
Body
In the body provide the uuid of the avatar you created for this cash register. Also make sure to provide a unique name for your cash register. Set the status to PENDING_APPROVAL.
Response
The response contains the id of the cash register you created. Save this id. You will need it to create subsequent tabs and tab items.
4b. Wait for approval
On the production environment, a bunq admin will review and approve your cash register. In the sandbox environment, your cash register will be automatically approved.
5. POST tab-usage-single
Create a new tab that is connected to your cash register. Use the id of the cash register you want to connect this tab to in the URL of your request.
Body
Give the tab a name in merchant_reference. Create the tab with status OPEN, and give the tab a starting amount. You can update this amount later.
Response
The response contains the uuid of the tab you created.
6. POST tab-item (optional)
You can add items to a tab. For instance, if a customer will be paying for multiple products via this tab, you can decide to add an item for each of these. Adding items to a tab is optional, and adding them will not change the total amount of the tab itself. However, if you've added any tab items the sum of the amounts of these items must be equal to the totalamount of the tab when you change its status to WAITINGFOR_PAYMENT.
7. PUT tab-usage-single
Update the status of the tab to WAITINGFORPAYMENT if you want the costumer to pay the tab, and you're done adding any tab items. You can use this request to make the tab visible for your costumers.
Visibility
To decide how you are going to make your tab visible, pass a visibility object in the payload.
Setting cashregisterqr_code to true will connect this tab to the QR code from the cash register. If this cash register does not have a QR code yet, one will be created. Only one Tab can be connected to the cash register’s QR code at any given time.
Setting tabqrcode to true will create a QR code specifically for this tab. This QR code can not be linked to anything else.
Quickstart: Create a TransferWise payment
Goal
You want to send a payment in currency other than euro outside the SEPA zone.
Before you start
Make sure that you have opened a session and that for any call you make after that, you pass the session’s token in the X-Bunq-Client-Authentication header.
ℹ️ bunq relies on TransferWise for international, so you need to create a TransferWise account linked to a bunq account to be able to create international transfers. You can do it either from the bunq app or using our API as described below.
Get the up-to-date exchange rate (optional)
You might want to check the latest currency exchange rate before making a transfer. Here’s how you can do it using the bunq API:
Check the list of supported currencies via GET /user/{userID}/transferwise-currency. Copy the needed currency code.
Create a temporary quote for the currency of your choice via POST /user/{userID}/transferwise-quote-temporary.
ℹ️ A quote is the exchange rate at the exact timestamp. Temporary quotes carry solely informative value and cannot be used for creating a transfer.
Read the temporary quote via GET /user/{userID}/transferwise-quote-temporary/{transferwise-quote-temporaryID}.
Create a TransferWise account
You need a TransferWise account linked to your bunq account to make TransferWise payments via the bunq API. Create one via POST /user/{userID}/transferwise-user, and save its ID.
ℹ️ You cannot use an existing TransferWise account.
Create a quote
Create a quote via POST /user/{userID}/transferwise-quote and save its ID.
ℹ️ Use amounttarget to indicate the sum the recipient must get. Amountsource, on the other hand, will indicate the sum you want to send, but it will not necessarily be the final sum the recipient gets.
ℹ️ Quotes are valid for 30 minutes so if you do not manage to create a transfer within this time, you will need to create another quote.
Get the exchange rate by reading the quote via GET /user/{userID}/transferwise-quote/(transferwise-quoteID).
Create a recipient
If you have sent money via the TransferWise account linked to your bunq account, you can reuse the recipients. You can list their IDs via GET /user/{userID}/transferwise-quote/{transferwise-quoteID}/transferwise-recipient.
To create a new, previously unused recipient, follow these steps:
Retrieve the fields required for creating the recipient as the requirements vary for the type of recipient in each country. Iterate sending the following request pair till there are no more required fields:
GET /user/{userID}/transferwise-quote/{transferwise-quoteID}/transferwise-recipient-requirement
POST /user/{userID}/transferwise-quote/{transferwise-quoteID}/transferwise-recipient-requirement
Create a recipient account using the final request body from the previous step with POST /user/{userID}/transferwise-quote/{transferwise-quoteID}/transferwise-recipient-requirement
Create a transfer
Finally, having both the quote ID and the recipient ID, you can create a transfer. 🎉
Check if there are any additional transfer requirements via POST /user/{userID}/transferwise-quote/{transferwise-quoteID}/transferwise-transfer-requirement.
Create a transfer via POST /user/{userID}/transferwise-quote/{transferwise-quoteID}/transferwise-transfer. You need to specify the ID of the monetary account from which you want the payment to be made.
Quickstart: Downloading attachments
Goal
Export receipts and invoices attached to payments to your application.
The scenario you want to achieve
The bunq user has accepted the authorization request and your application can read the bunq user’s account information.
Your application imports all the transactions and attachments.
The bunq user sees the transactions matched with the receipts and invoices in your application.
Before you start
Make sure that you have opened a session
Make sure you pass the session Token in the X-Bunq-Client-Authentication header in all the following requests of the session.
Call sequence
List the payments of the user via GET /user/{userID}/monetary-account/{monetary-accountID}/payment.
Check if the payments have attachments via GET /user/{userID}/monetary-account/{monetary-accountID}/payment/{paymentID}/note-attachment. Save the attachment IDs.
Export the raw content of the attachments via GET /user/{userID}/attachment/{attachmentID}/content.
HINT: You can use callbacks to make sure you don’t miss anything happening on the bunq account.

API Documentation
Instant Payments Notifications
IPN (Instant payment notifications, or callbacks) are used to notify you when transaction status is changed.
To use them, you should complete the following steps:
Generate and save the IPN Secret key in Store Settings tab at the Dashboard.
Insert your URL address where you want to get callbacks in createpayment request. The parameter name is ipn\callback\_url. You will receive payment updates (statuses) to this URL address.
You will receive all the parameters at the URL address you specified in (2) by POST request.
The POST request will contain the x-nowpayments-sig parameter in the header.
The body of the request is similiar to a get payment status response body.
Example:
{"paymentid":5077125051,"paymentstatus":"waiting","payaddress":"0xd1cDE08A07cD25adEbEd35c3867a59228C09B606","priceamount":170,"pricecurrency":"usd","payamount":155.38559757,"actuallypaid":0,"paycurrency":"mana","orderid":"2","orderdescription":"Apple Macbook Pro 2019 x 1","purchaseid":"6084744717","createdat":"2021-04-12T14:22:54.942Z","updatedat":"2021-04-12T14:23:06.244Z","outcomeamount":1131.7812095,"outcome_currency":"trx"}
Sort all the parameters from the POST request in alphabetical order.
Convert them to string using
JSON.stringify (params, Object.keys(params).sort()) or the same function.
Sign a string with an IPN-secret key with HMAC and sha-512 key
Compare the signed string from the previous step with the x-nowpayments-sig , which is stored in the header of the callback request.
If these strings are similar it is a success.
Otherwise, contact us on [email protected] to solve the problem.
Example of creating a signed string at Node.JS
const hmac = crypto.createHmac('sha512', notificationsKey);
hmac.update(JSON.stringify(params, Object.keys(params).sort()));
const signature = hmac.digest('hex');
Example of comparing signed strings in PHP
function checkipnrequestisvalid()
{
$error_msg = "Unknown error";
$auth_ok = false;
$request_data = null;
if (isset($SERVER['HTTPXNOWPAYMENTSSIG']) && !empty($SERVER['HTTPXNOWPAYMENTSSIG'])) {
$recivedhmac = $SERVER['HTTPXNOWPAYMENTS_SIG'];
$requestjson = fileget_contents('php://input');
$requestdata = jsondecode($request_json, true);
ksort($request_data);
$sortedrequestjson = jsonencode($requestdata);
if ($requestjson !== false && !empty($requestjson)) {
$hmac = hashhmac("sha512", $sortedrequestjson, trim($this->ipnsecret));
if ($hmac == $recived_hmac) {
$auth_ok = true;
} else {
$error_msg = 'HMAC signature does not match';
}
} else {
$error_msg = 'Error reading POST data';
}
} else {
$error_msg = 'No HMAC signature sent.';
}
}
Recurrent payment notifications
If an error is detected, the payment is flagged and will receive additional recurrent notifications (number of recurrent notifications can be changed in your Store Settings-> Instant Payment Notifications).
If an error is received again during processing of the payment, recurrent notifications will be initiated again.
Example: "Timeout" is set to 1 minute and "Number of recurrent notifications" is set to 3.
Once an error is detected, you will receive 3 notifications at 1 minute intervals.
Several payments for one order
If you want to create several payments for one Order you should do the following:
Create a payment for the full order amount.
Save "purchaseid" which will be in "createpayment" response
Create next payment or payments with this "purchaseid" in "createpayment" request.
Only works for partially_paid payments
It may be useful if you want to give your customers opportunity to pay a full order with several payments, for example, one part in BTC and one part in ETH. Also, if your customer accidentally paid you only part of a full amount, you can automatically ask them to make another payment.

The Production endpoint provides access to your live user data. Sandbox tenants are a good place to test code without affecting real-world data. If you would like Zuora to provision a Sandbox tenant for you, contact your Zuora representative for assistance.
If you do not have a Zuora tenant, go to https://www.zuora.com/resource/zuora-test-drive and sign up for a Production Test Drive tenant. The tenant comes with seed data, including a sample product catalog.

Authentication
OAuth v2.0
Zuora recommends that you use OAuth v2.0 to authenticate to the Zuora REST API. Currently, OAuth is not available in every environment. See Zuora Testing Environments for more information.
Zuora recommends you to create a dedicated API user with API write access on a tenant when authenticating via OAuth, and then create an OAuth client for this user. See Create an API User for how to do this. By creating a dedicated API user, you can control permissions of the API user without affecting other non-API users.
If a user is deactivated, all of the user's OAuth clients will be automatically deactivated.
Authenticating via OAuth requires the following steps:
Create a Client
Generate a Token
Make Authenticated Requests
Create a Client
You must first create an OAuth client in the Zuora UI. To do this, you must be an administrator of your Zuora tenant. This is a one-time operation. You will be provided with a Client ID and a Client Secret. Please note this information down, as it will be required for the next step.
Note: The OAuth client will be owned by a Zuora user account. If you want to perform PUT, POST, or DELETE operations using the OAuth client, the owner of the OAuth client must have a Platform role that includes the "API Write Access" permission.
Generate a Token
After creating a client, you must make a call to obtain a bearer token using the Generate an OAuth token operation. This operation requires the following parameters:
client_id - the Client ID displayed when you created the OAuth client in the previous step
client_secret - the Client Secret displayed when you created the OAuth client in the previous step
granttype - must be set to clientcredentials
Note: The Client ID and Client Secret mentioned above were displayed when you created the OAuth Client in the prior step. The Generate an OAuth token response specifies how long the bearer token is valid for. You should reuse the bearer token until it is expired. When the token is expired, call Generate an OAuth token again to generate a new one.
Make Authenticated Requests
To authenticate subsequent API requests, you must provide a valid bearer token in an HTTP header:
Authorization: Bearer {bearer_token}
If you have Zuora Multi-entity enabled, you need to set an additional header to specify the ID of the entity that you want to access. You can use the scope field in the Generate an OAuth token response to determine whether you need to specify an entity ID.
If the scope field contains more than one entity ID, you must specify the ID of the entity that you want to access. For example, if the scope field contains entity.1a2b7a37-3e7d-4cb3-b0e2-883de9e766cc and entity.c92ed977-510c-4c48-9b51-8d5e848671e9, specify one of the following headers:
Zuora-Entity-Ids: 1a2b7a37-3e7d-4cb3-b0e2-883de9e766cc
Zuora-Entity-Ids: c92ed977-510c-4c48-9b51-8d5e848671e9
Note: For a limited period of time, Zuora will accept the entityId header as an alternative to the Zuora-Entity-Ids header. If you choose to set the entityId header, you must remove all "-" characters from the entity ID in the scope field.
If the scope field contains a single entity ID, you do not need to specify an entity ID.
Other Supported Authentication Schemes
Zuora continues to support the following additional legacy means of authentication:
Use username and password. Include authentication with each request in the header:
apiAccessKeyId
apiSecretAccessKey
Zuora recommends that you create an API user specifically for making API calls. See Create an API User for more information.
Use an authorization cookie. The cookie authorizes the user to make calls to the REST API for the duration specified in Administration > Security Policies > Session timeout. The cookie expiration time is reset with this duration after every call to the REST API. To obtain a cookie, call the Connections resource with the following API user information:
ID
Password
For CORS-enabled APIs only: Include a 'single-use' token in the request header, which re-authenticates the user with each request. See below for more details.
Entity Id and Entity Name
The entityId and entityName parameters are only used for Zuora Multi-entity. These are the legacy parameters that Zuora will only continue to support for a period of time. Zuora recommends you to use the Zuora-Entity-Ids parameter instead.
The entityId and entityName parameters specify the Id and the name of the entity that you want to access, respectively. Note that you must have permission to access the entity.
You can specify either the entityId or entityName parameter in the authentication to access and view an entity.
If both entityId and entityName are specified in the authentication, an error occurs.
If neither entityId nor entityName is specified in the authentication, you will log in to the entity in which your user account is created.
To get the entity Id and entity name, you can use the GET Entities REST call. For more information, see API User Authentication.
Token Authentication for CORS-Enabled APIs
The CORS mechanism enables REST API calls to Zuora to be made directly from your customer's browser, with all credit card and security information transmitted directly to Zuora. This minimizes your PCI compliance burden, allows you to implement advanced validation on your payment forms, and makes your payment forms look just like any other part of your website.
For security reasons, instead of using cookies, an API request via CORS uses tokens for authentication.
The token method of authentication is only designed for use with requests that must originate from your customer's browser; it should not be considered a replacement to the existing cookie authentication mechanism.
See Zuora CORS REST for details on how CORS works and how you can begin to implement customer calls to the Zuora REST APIs. See HMAC Signatures for details on the HMAC method that returns the authentication token.
Requests and Responses
Request IDs
As a general rule, when asked to supply a "key" for an account or subscription (accountKey, account-key, subscriptionKey, subscription-key), you can provide either the actual ID or the number of the entity.
HTTP Request Body
Most of the parameters and data accompanying your requests will be contained in the body of the HTTP request.
The Zuora REST API accepts JSON in the HTTP request body. No other data format (e.g., XML) is supported.
Data Type
(Actions and CRUD operations only) We recommend that you do not specify the decimal values with quotation marks, commas, and spaces. Use characters of +-0-9.eE, for example, 5, 1.9, -8.469, and 7.7e2. Also, Zuora does not convert currencies for decimal values.
Testing a Request
Use a third party client, such as curl, Postman, or Advanced REST Client, to test the Zuora REST API.
You can test the Zuora REST API from the Zuora API Sandbox or Production tenants. If connecting to Production, bear in mind that you are working with your live production data, not sample data or test data.
Testing with Credit Cards
Sooner or later it will probably be necessary to test some transactions that involve credit cards. For suggestions on how to handle this, see [Going Live With Your Payment Gateway](https://knowledgecenter.zuora.com/CBBilling/MPaymentGateways/CManagingPaymentGateways/BGoingLivePaymentGateways#TestingwithCreditCards "CZuoraUserGuides/ABillingandPayments/MPaymentGateways/CManagingPaymentGateways/BGoingLivePaymentGateways#TestingwithCredit_Cards"
).
Concurrent Request Limits
Zuora enforces tenant-level concurrent request limits. See Concurrent Request Limits for more information.
Timeout Limit
If a request does not complete within 120 seconds, the request times out and Zuora returns a Gateway Timeout error.
Error Handling
If a request to Zuora Billing REST API with an endpoint starting with /v1 (except Actions and CRUD operations) fails, the response will contain an eight-digit error code with a corresponding error message to indicate the details of the error.
The following code snippet is a sample error response that contains an error code and message pair:
The success field indicates whether the API request has succeeded. The processId field is a Zuora internal ID that you can provide to Zuora Global Support for troubleshooting purposes.
The reasons field contains the actual error code and message pair. The error code begins with 5 or 6 means that you encountered a certain issue that is specific to a REST API resource in Zuora Billing. For example, 53100320 indicates that an invalid value is specified for the termType field of the subscription object.
The error code beginning with 9 usually indicates that an authentication-related issue occurred, and it can also indicate other unexpected errors depending on different cases. For example, 90000011 indicates that an invalid credential is provided in the request header.
When troubleshooting the error, you can divide the error code into two components: REST API resource code and error category code. See the following Zuora error code sample:
Note: Zuora determines resource codes based on the request payload. Therefore, if GET and DELETE requests that do not contain payloads fail, you will get 500000 as the resource code, which indicates an unknown object and an unknown field.
The error category code of these requests is valid and follows the rules described in the Error Category Code section.
In such case, you can refer to the returned error message to troubleshoot.
REST API Resource Code
The 6-digit resource code indicates the REST API resource, typically a field of a Zuora object, on which the issue occurs. In the preceding example, 531003 refers to the termType field of the subscription object.
The value range for all REST API resource codes is from 500000 to 679999. See Resource Codes in the Knowledge Center for a full list of resource codes.
Error Category Code
The 2-digit error category code identifies the type of error, for example, resource not found or missing required field.
The following table describes all error categories and the corresponding resolution:
| Code | Error category | Description | Resolution |
|:--------|:--------|:--------|:--------|
| 10 | Permission or access denied | The request cannot be processed because a certain tenant or user permission is missing. | Check the missing tenant or user permission in the response message and contact Zuora Global Support for enablement. |
| 11 | Authentication failed | Authentication fails due to invalid API authentication credentials. | Ensure that a valid API credential is specified. |
| 20 | Invalid format or value | The request cannot be processed due to an invalid field format or value. | Check the invalid field in the error message, and ensure that the format and value of all fields you passed in are valid. |
| 21 | Unknown field in request | The request cannot be processed because an unknown field exists in the request body. | Check the unknown field name in the response message, and ensure that you do not include any unknown field in the request body. |
| 22 | Missing required field | The request cannot be processed because a required field in the request body is missing. | Check the missing field name in the response message, and ensure that you include all required fields in the request body. |
| 30 | Rule restriction | The request cannot be processed due to the violation of a Zuora business rule. | Check the response message and ensure that the API request meets the specified business rules. |
| 40 | Not found | The specified resource cannot be found. | Check the response message and ensure that the specified resource exists in your Zuora tenant. |
| 45 | Unsupported request | The requested endpoint does not support the specified HTTP method. | Check your request and ensure that the endpoint and method matches. |
| 50 | Locking contention | This request cannot be processed because the objects this request is trying to modify are being modified by another API request, UI operation, or batch job process. | Resubmit the request first to have another try. If this error still occurs, contact Zuora Global Support with the returned Zuora-Request-Id value in the response header for assistance. |
| 60 | Internal error | The server encounters an internal error. | Contact Zuora Global Support with the returned Zuora-Request-Id value in the response header for assistance. |
| 70 | Request exceeded limit | The total number of concurrent requests exceeds the limit allowed by the system. | Resubmit the request after the number of seconds specified by the Retry-After value in the response header. Check Concurrent request limits for details about Zuora’s concurrent request limit policy. |
| 90 | Malformed request | The request cannot be processed due to JSON syntax errors. | Check the syntax error in the JSON request body and ensure that the request is in the correct JSON format. |
| 99 | Integration error | The server encounters an error when communicating with an external system, for example, payment gateway, tax engine provider. | Check the response message and take action accordingly. |
Pagination
When retrieving information (using GET methods), the optional pageSize query parameter sets the maximum number of rows to return in a response. The maximum is 40; larger values are treated as 40. If this value is empty or invalid, pageSize typically defaults to 10.
The default value for the maximum number of rows retrieved can be overridden at the method level.
If more rows are available, the response will include a nextPage element, which contains a URL for requesting the next page. If this value is not provided, no more rows are available. No "previous page" element is explicitly provided; to support backward paging, use the previous call.
Array Size
For data items that are not paginated, the REST API supports arrays of up to 300 rows. Thus, for instance, repeated pagination can retrieve thousands of customer accounts, but within any account an array of no more than 300 rate plans is returned.
API Versions
The Zuora REST API are version controlled. Versioning ensures that Zuora REST API changes are backward compatible. Zuora uses a major and minor version nomenclature to manage changes. By specifying a version in a REST request, you can get expected responses regardless of future changes to the API.
Major Version
The major version number of the REST API appears in the REST URL. Currently, Zuora only supports the v1 major version. For example, POST https://rest.zuora.com/v1/subscriptions.
Minor Version
Zuora uses minor versions for the REST API to control small changes. For example, a field in a REST method is deprecated and a new field is used to replace it.
Some fields in the REST methods are supported as of minor versions. If a field is not noted with a minor version, this field is available for all minor versions. If a field is noted with a minor version, this field is in version control. You must specify the supported minor version in the request header to process without an error.
If a field is in version control, it is either with a minimum minor version or a maximum minor version, or both of them. You can only use this field with the minor version between the minimum and the maximum minor versions. For example, the invoiceCollect field in the POST Subscription method is in version control and its maximum minor version is 189.0. You can only use this field with the minor version 189.0 or earlier.
If you specify a version number in the request header that is not supported, Zuora will use the minimum minor version of the REST API. In our REST API documentation, if a field or feature requires a minor version number, we note that in the field description.
You only need to specify the version number when you use the fields require a minor version. To specify the minor version, set the zuora-version parameter to the minor version number in the request header for the request call. For example, the collect field is in 196.0 minor version. If you want to use this field for the POST Subscription method, set the zuora-version parameter to 196.0 in the request header. The zuora-version parameter is case sensitive.
For all the REST API fields, by default, if the minor version is not specified in the request header, Zuora will use the minimum minor version of the REST API to avoid breaking your integration.
Minor Version History
The supported minor versions are not serial. This section documents the changes made to each Zuora REST API minor version.
The following table lists the supported versions and the fields that have a Zuora REST API minor version.

GOV.UK Pay API (This version is no longer maintained. See openapi/publicapi_spec.json for latest API specification)

This is an API designed for merchants who are using SpectroCoin services and wishes to integrate them locally.

Summary
The Swiss NextGen API is based on the NextGenPSD2 Framework Version 1.3.4 of the Berlin Group which offers a modern, open, harmonised and interoperable set of
Application Programming Interfaces (APIs) as the safest and most efficient way to provide data securely.
The NextGen Framework reduces XS2A complexity and costs, addresses the problem of multiple competing standards
in Europe and, aligned with the goals of the Euro Retail Payments Board,
enables European banking customers to benefit from innovative products and services ('Banking as a Service')
by granting TPPs safe and secure (authenticated and authorised) access to their bank accounts and financial data.
The Swiss edtion refines the message formats specific to Switzerland and defines some matching examples.
The possible Approaches are:
Redirect SCA Approach
(Not recommended by obp.ch community) OAuth SCA Approach
(Not recommended by obp.ch community) Decoupled SCA Approach
(Not recommended by obp.ch community) Embedded SCA Approach without SCA method
(Not recommended by obp.ch community) Embedded SCA Approach with only one SCA method available
(Not recommended by obp.ch community) Embedded SCA Approach with Selection of a SCA method
Not every message defined in this API definition is necessary for all approaches.
Furthermore this API definition does not differ between methods which are mandatory, conditional, or optional
Therefore for a particular implementation of a compliant API it is only necessary to support
a certain subset of the methods defined in this API definition.
**Please have a look at the implementation guidelines if you are not sure
which message has to be used for the approach you are going to use.**
Some General Remarks Related to this version of the OpenAPI Specification:
This API definition is based on the Implementation Guidelines of the Berlin Group API.
It is not a replacement in any sense.
The main specification is (at the moment) always the Implementation Guidelines of the Berlin Group API.
This API definition contains the REST-API for requests from the PISP to the ASPSP.
This API definition contains the messages for all different approaches defined in the Implementation Guidelines.
According to the OpenAPI-Specification [https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.1.md]
"If in is "header" and the name field is "Accept", "Content-Type" or "Authorization", the parameter definition SHALL be ignored."
The element "Accept" will not be defined in this file at any place.
The elements "Content-Type" and "Authorization" are implicitly defined by the OpenApi tags "content" and "security".
There are several predefined types which might occur in payment initiation messages,
but are not used in the standard JSON messages in the Implementation Guidelines.
Therefore they are not used in the corresponding messages in this file either.
We added them for the convenience of the user.
If there is a payment product, which needs these fields, one can easily use the predefined types.
But the ASPSP need not to accept them in general.
**We omit the definition of all standard HTTP header elements (mandatory/optional/conditional)
except they are mentioned in the Implementation Guidelines.**
Therefore the implementer might add these in his own realisation of a comlient API in addition to the elements defined in this file.
General Remarks on Data Types
The Berlin Group definition of UTF-8 strings in context of the API have to support at least the following characters
a b c d e f g h i j k l m n o p q r s t u v w x y z
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
0 1 2 3 4 5 6 7 8 9
