I'm sorry but after many tests and configurations, I have to ask for help! The message is clear 'UNAUTHORIZED_PAYMENT' but I followed all the settings but the problem remains! My condition is this: c # class (.net 4.0) referenced to PayPal SDK (ver.1.9.1)! Sandbox operations are ok! "Mode / clientid / secretid" is set in the configuration file! Business Profile is active! Authentication and tokens arrive regularly! the result is always the same
WEBSN3S041 10/0[Removed. Phone #s not permitted]br />The remote server returned an error: (401) Unauthorized.
{"name": "UNAUTHORIZED_PAYMENT", "message": "Unauthorized payment.", "information_link": "https://developer.paypal.com/docs/api/payments/#errors", "debug_id": "40e5e1e9ebe4f "}
After 4 days (maybe more), I give up!
Thank you all for your help
