I am using the PHP SDK to process payments via customerProfileId and customerPaymentProfileId. The same implementation was working properly last Friday; however, it is now consistently returning the following error:
Nothing has changed in my code, and I’ve verified that both the customerProfileId and paymentProfileId are valid and active in the sandbox environment. Despite this, the transactions are now failing.
