Hi, I'm using PayPal NVP API with PayPal Sandbox account for testing. After submitting the request I get the following error from PayPal: "Error 10501: Invalid Configuration. This transaction cannot be processed due to an invalid merchant configuration." I'm using api username, password and signature to access my merchant account. Could anyone help me to solve this? Thanks in advance.
