Hi Andy,
My apologies as we currently do not have call examples that utilizes POSTMAN or entire calls via cURL. However, you can refer to our
call structure and
API call example guides to have an idea how to structure each call without the use of a client library.
Additionally, if my understanding is correct that you also wish to retrieve all client account information under a specific MCC, then I'm afraid that there is currently no service that supports this. For now, you may follow our
blog for updates.
Thanks and regards,
Peter
