Initial token retrieval

When integrating we’ll suggest the grant_type to use, in most cases this will be client_credentials. This returns an access_token ready to be used, and also a refresh_token which you can use to refresh the access_token when it expires.

Client Credentials

POST URL: <address>/token

Parameter (x-www-form-urlencoded)

Parameter	Description	Example

Parameter	Description	Example
grant_type	Set to 'client_credentials'	client_credentials
client_id	The client_id given to you to identify your application, You must ensure that you base64 encode this if it hasn’t been already. (It generally has == at the end when encoded)	assdasd==
client_secret	The client_secret given to you to identify your application, You must ensure that you base64 encode this if it hasn’t been already. (It generally has == at the end when encoded)	asfsafsa121==

Authorization Code

URL : https://<address>/Authorize?response_type=code&client_id=123456789&redirect_uri=https://example-app.com/redirect&scope=create_and_delete&state=xcoiv98y2kd22vusuye3kch

URL Parameters

Parameter	Description	Example

Parameter	Description	Example
response_type	response type	code
client_id	client id provided	1234567890
redirect_uri	Registered redirect URL	https://example-app.com/redirect
scope	Access scope	create_and_delete
state	state	xcoiv98y2kd22vusuye3kch

If the user approves the request, the authorization server will redirect the browser back to the redirect_uri specified by the application, adding a code and state to the query string.

Ex: https://example-app.com/redirect?code=g0ZGZmNjVmOWIjNTk2NTk4ZTYyZGI3&state=xcoiv98y2kd22vusuye3kch

Exchange the Authorization Code for an Access Token

makes a POST request to the service’s token endpoint(<address>/Token) with the following parameters:

Parameter	Note

Parameter	Note
grant_type	"authorization_code", This tells the token endpoint that the application is using the Authorization Code grant type.
code	The authorization code given in the redirect.
client_id	The application’s client ID.
client_secret	The application’s client secret. This ensures that the request to get the access token is made only from the application, and not from a potential attacker that may have intercepted the authorization code.
redirect_uri	The same redirect URI that was used when requesting the code.

The token endpoint will verify all the parameters in the request, ensuring the code hasn’t expired and that the client ID and secret match. If everything checks out, it will generate an access token and return it in the response!
