Mock sample for your project: Portfolio Optimizer API

Introduction
The Business Registries API is built on HTTP. The API is RESTful. It has predictable resource URIs.
The API is documented in OpenAPI format.
In addition to the standard OpenAPI syntax we use a few
vendor extensions.
Overview
The following sections describe the resources that make up the Business Registries REST API.
Current Version
By default, all requests to https://api.abr.ato.gov.au receive the v1 version of the REST API. We encourage you to explicitly request this version via the Accept header.
Accept: application/vnd.abr-ato.v1+json
Schema
All API access is over HTTPS, and accessed from https://api.abr.ato.gov.au. All data is sent and received as JSON. Blank fields are included.
All dates use the ISO 8601 format:
YYYY-MM-DD
For example: 2017-07-01 (the 1st of July 2017)
All timestamps use the ISO 8601 format:
YYYY-MM-DDTHH:MM:SSZ
For example: 2017-07-01T11:05:06+10:00
Timezones
Some requests allow for specifying timestamps or generate timestamps with time zone information. We apply the following rules, in order of priority, to determine timezone information for API calls.
Explicitly provide an ISO 8601 timestamp with timezone information
For API calls that allow for a timestamp to be specified, we use that exact timestamp.
For example: 2017-07-01T11:05:06+10:00
Pagination
Information about pagination is provided in the Link header.
For example:
Link:; rel="next",; rel="last"
rel="next" states that the next page is page=2. This makes sense, since by default, all paginated queries start at page 1. rel="last" provides some more information, stating that the last page of results is on page 34. Accordingly, we have 33 more pages of information that we can consume.
Parameters
Many API methods take optional parameters:
GET /individuals/1234/addresses/?addressType='Mailing'
In this example, the '1234' value is provided for the :partyId parameter in the path while :addressType is passed in the query string.
For POST, PATCH, PUT, and DELETE requests, parameters not included in the URL should be encoded as JSON with a Content-Type of 'application/json'.
Metadata
The API provides metadata services that you can use to discover information about the classifcation schemes and values used by the Registry.
For example:
GET /classifications/roles
Sample response:
[
{
"id": "123e4567-e89b-12d3-a456-426655440001",
"role": "Director",
"roleDescription": "An individual responsible for managing a company's ...",
"relationship": "Directorship",
"reciprocalRole": "Company",
"reciprocalRoleDescription": "An incorporated legal entity."
},
{
...
}
]
Root Endpoint
You can issue a GET request to the root endpoint (also known as the service root) to get all the endpoint categories that the REST API supports:
curl https://api.abr.ato.gov.au
Authentication
The Business Registries API supports API Key authentication.
When you sign up for an account, you are given your first API key. You can generate additional API keys, and delete
API keys (as you may need to rotate your keys in the future). You authenticate to the Business Registries API by
providing your secret key in the request header.
Note: Some requests will return 404 Not Found, instead of 403 Permission Denied. This is to prevent the
accidental leakage of information to unauthorised users.

Storecove API

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
}
}
Sample Example
{
"secureContent": {
"key": "eS3aw6H/qzHMJ00gSi6gQ3xa08DPMazk8BFY96Pd99ODA==",
"iv": "NLyXMGq9svw0XO5aI9BzWw==",
"content": "gAEOiQltO1w+LzGUoIK8FiYbU42hug94EasSl7N+Q1w="
}
