Fire Financial Services Business API
The fire.com API allows you to deeply integrate Business Account features into your application or back-office systems.
The API provides read access to your profile, accounts and transactions, event-driven notifications of activity on the account and payment initiation via batches. Each feature has its own HTTP endpoint and every endpoint has its own permission.
The API exposes 3 main areas of functionality: financial functions, service information and service configuration.
Financial Functions
These functions provide access to your account details, transactions, payee accounts, payment initiation etc.
Service Functions
These provide information about the fees and limits applied to your account.
Service configuration
These provide information about your service configs - applications, webhooks, API tokens, etc.

Paylocity API
paylocity.com
For general questions and support of the API, contact: [email protected]
Overview
Paylocity Web Services API is an externally facing RESTful Internet protocol. The Paylocity API uses HTTP verbs and a RESTful endpoint structure. OAuth 2.0 is used as the API Authorization framework. Request and response payloads are formatted as JSON.
Paylocity supports v1 and v2 versions of its API endpoints. v1, while supported, won't be enhanced with additional functionality. For direct link to v1 documentation, please click here. For additional resources regarding v1/v2 differences and conversion path, please contact [email protected].
Setup
Paylocity will provide the secure client credentials and set up the scope (type of requests and allowed company numbers). You will receive the unique client id, secret, and Paylocity public key for the data encryption. The secret will expire in 365 days.
Paylocity will send you an e-mail 10 days prior to the expiration date for the current secret. If not renewed, the second e-mail notification will be sent 5 days prior to secret's expiration. Each email will contain the code necessary to renew the client secret.
You can obtain the new secret by calling API endpoint using your current not yet expired credentials and the code that was sent with the notification email. For details on API endpoint, please see Client Credentials section.
Both the current secret value and the new secret value will be recognized during the transition period. After the current secret expires, you must use the new secret.
If you were unable to renew the secret via API endpoint, you can still contact Service and they will email you new secret via secure email.
When validating the request, Paylocity API will honor the defaults and required fields set up for the company default New Hire Template as defined in Web Pay.
Authorization
Paylocity Web Services API uses OAuth2.0 Authentication with JSON Message Format.
All requests of the Paylocity Web Services API require a bearer token which can be obtained by authenticating the client with the Paylocity Web Services API via OAuth 2.0.
The client must request a bearer token from the authorization endpoint:
auth-server for production: https://api.paylocity.com/IdentityServer/connect/token
auth-server for testing: https://apisandbox.paylocity.com/IdentityServer/connect/token
Paylocity reserves the right to impose rate limits on the number of calls made to our APIs. Changes to API features/functionality may be made at anytime with or without prior notice.
Authorization Header
The request is expected to be in the form of a basic authentication request, with the "Authorization" header containing the client-id and client-secret. This means the standard base-64 encoded user:password, prefixed with "Basic" as the value for the Authorization header, where user is the client-id and password is the client-secret.
Content-Type Header
The "Content-Type" header is required to be "application/x-www-form-urlencoded".
Additional Values
The request must post the following form encoded values within the request body:
granttype = clientcredentials
scope = WebLinkAPI
Responses
Success will return HTTP 200 OK with JSON content:
{
"access_token": "xxx",
"expires_in": 3600,
"token_type": "Bearer"
}
Encryption
Paylocity uses a combination of RSA and AES cryptography. As part of the setup, each client is issued a public RSA key.
Paylocity recommends the encryption of the incoming requests as additional protection of the sensitive data. Clients can opt-out of the encryption during the initial setup process. Opt-out will allow Paylocity to process unencrypted requests.
The Paylocity Public Key has the following properties:
2048 bit key size
PKCS1 key format
PEM encoding
Properties
key (base 64 encoded): The AES symmetric key encrypted with the Paylocity Public Key. It is the key used to encrypt the content. Paylocity will decrypt the AES key using RSA decryption and use it to decrypt the content.
iv (base 64 encoded): The AES IV (Initialization Vector) used when encrypting the content.
content (base 64 encoded): The AES encrypted request. The key and iv provided in the secureContent request are used by Paylocity for decryption of the content.
We suggest using the following for the AES:
CBC cipher mode
PKCS7 padding
128 bit block size
256 bit key size
Encryption Flow
Generate the unencrypted JSON payload to POST/PUT
Encrypt this JSON payload using your own key and IV (NOT with the Paylocity public key)
RSA encrypt the key you used in step 2 with the Paylocity Public Key, then, base64 encode the result
Base64 encode the IV used to encrypt the JSON payload in step 2
Put together a "securecontent" JSON object:
{
'secureContent' : {
'key' : -- RSA-encrypted & base64 encoded key from step 3,
'iv' : -- base64 encoded iv from step 4
'content' -- content encrypted with your own key from step 2, base64 encoded
}
}

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.
