After successfully creating both an Apple Merchant Identifier certificate and Apple Payment Processing certificate, I keep getting the following error after clicking the ApplePay button in the cart:
Could not start Apple Pay session: 400 Bad Request
{
"statusMessage": "Payment Services Exception merchantId=51nnnnn unauthorized to service on behalf of merchantId=9Cnnnn reason=\"The latter never authorized the former\"",
"statusCode": "400"
}
The domain has been successfully registered in the Salesforce Commerce Cloud Business Manager and we've verified the credentials being used for the ApplePay and Payment provider accounts.
