Hi Justin, The API credentials work fine when I use it in a SOAP request. But in NVP, I tried different ways to use these credentials, through Postman client and browser too, but no luck. Can you pls confirm whether I need to pass these credentials as parameters in the url along with other parameters, as mentioned above, or do I need to pass them in request headers? Also the PayPal documentation doesn’t have any details about how to use API credentials for NVP format. Thanks, Vitthal
