I am working for a product based company where we have integrated Apple pay with Gateways like freedompay, adyen and so on. We have dedicated product team managing anything related to payments. All the other products within our company use the services provided by Payments team. We are facing challenges in managing merchant domains as we have different DNS names for different customers.
We are adding each customer's domain in apple portal and we are doing the domain verification. As the customer count is more and the domain verification expires with the SSL certificate expiry, it is difficult to manage it.
Questions: We tried using the Register Merchant API in sandbox environment. We are facing 401 Unauthorized. Could you please let us know of process for using this API.
