We are just open an account. But we when we integrate PayPalpro we got "This transaction cannot be processed due to an invalid merchant configuration." error message. We searched in google and found the DPRP and billing agreement not enabled. Could you please enable this for my sandbox account "<removed>"
We are blocked due to the payment failure. Please help with this.
Note: we are integrating with PHP code and PayPal version is 57. and we are using "NVP" API.
