This is the second step after using the Create Subscription API that is authorized using the Client Access Token obtained from the response of the Client Access Token API.

This API returns a code that can be used later in the User Access Token (Using Authorization Code) API in order to obtain the User Access Token needed to use the Subscription Management section's APIs.

How to use:

1. Fill in Authorization header: Bearer C1234abcde-1234-abcd-1234-abcd1234abcd (Replace with access_token that starts with letter C obtained from response of Client Access Token API request).
2. Change the "pin" as per the user's input on the frontend PIN code input page and "purchaseToken" in the reqeust body as per the response of the Create Subscription API
