This endpoint is the final step in our OAuth Authentication Flow.
Use this endpoint to exchange a Authorization Code for a User Access Token, which can be used to access the rest of this API.
To ensure that your application does not retain unnecessary access to user data, revoke this access token in the event that is no longer required (e.g. the user deletes their account).
OAuth2 Error Responses
In keeping with the OAuth2 specification, error responses from this endpoint contain an error in the
error field, rather than the
message field used by other Akahu endpoints.
