We are currently struggling on the final stage… setting up payments. We have signed up for a PayPal pro account. I have got the API username, password and signature credentials and added them to the Smith Cart settings. However when I then run a test transaction, I get the following error:
We couldn't complete your payment.
Status : failure
Message : Invalid Configuration
Please help.
--------------------
This transaction cannot be processed due to an invalid merchant configuration occurs when you have not agreed to the billing agreement.
If you search this message in the paypal guide you will see a description of the message:
