I'm trying to do a DoDirectPayment
with the Sandbox API
I have been testing with code that I know works but my API credentials are getting the following error back from the Sandbox API
[L_ERRORCODE0] => 10501
[L_SHORTMESSAGE0] => Invalid Configuration
[L_LONGMESSAGE0] => This transaction cannot be processed due to an invalid merchant configuration
After looking up the error code I found that the problem "Occurs when the billing agreement is disabled or inactive."
I have searched Google intensively for how to Agree to the Billing Agreement in the sandbox but to no prevail
Has anyone had this issue and know how to switch it on?
