I am trying out Payment Pro in the sandbox, or at least I think I am. I have the API Credentials, using a signature and not a certificate. I am sending it through via a wordpress plugin that has been tested where other methods have worked. When I send the test transaction to the sandbox I get this: response received from PayPal Pro was: TIMESTAMP = 2010-03-01T02:35:52Z CORRELATIONID = eed9959ac72a ACK = Failure VERSION = 3.2 BUILD = 1195961 L_ERRORCODE0 = 10501 L_SHORTMESSAGE0 = Invalid Configuration L_LONGMESSAGE0 = This transaction cannot be processed due to an invalid merchant configuration. L_SEVERITYCODE0 = Error AMT = 500.00 CURRENCYCODE = USD But that error isn't really descriptive, I'm not sure what merchant configuration refer to. I mean the API certificate has 3 main fields, my configuration for the plugin has the same three main fields, it really isn't that complicated I think. Is it possible that I don't have pro set up, or does having a certificate mean I have pro set up. Also I am certain I created a credit card inside my buyers account, and that's the credit card number I'm using in my transaction, but it might not even be getting that far. Anybody have any ideas, or is there any way I can test this in a controlled environment to make sure it isn't an issue with my plugin?
