We’re testing debit card payment in sandbox environment using the Rest Pay Display API (see “Pay” API reference online interactive documentation) and always get the following error :
Transaction Declined: Serv not allowed. Card type cannot be processed on your merchant processing account.
The transaction amount is over 50$ with no cashback option. We have a B2 Canadian Interac test card, and also tried multiple real debit cards as suggested by a Clover employee in this thread, they all return the above error message. Another thread response by the same employee suggests to send an email at email@example.com (now firstname.lastname@example.org) in order to activate this functionality, I've done that but got no response.
Any idea why debit card payment is not working?
Here’s a request sent to the Rest Pay Display API that returns the error:
