The partner is attempting to send a message using the Axway B2Bi tool. I have configured authentication with both Basic and OAuth, but in both cases, I receive the same 401 error.</P><P>Interestingly, when I test the same interface using Postman with the same set of credentials, it works successfully.</P><P>Could anyone who has worked with Axway B2Bi provide some insights on how this issue can be debugged?</P><P>&nbsp;</P><P>Thank You,</P><P>Aditya</P> Thu, 11 Sep 2025 11:43:11 GMT https://community.sap.com/t5/technology-q-a/getting-401-unauthorized-error-while-triggering-a-message-from-axway-b2bi/qaq-p/14214571 aditya_20 2025-09-11T11:43:11Z https://community.sap.com/t5/technology-q-a/getting-401-unauthorized-error-while-triggering-a-message-from-axway-b2bi/qaa-p/14214666#M4925972 Fixing a 401 is going to have to be performed by the partner sending the message because the code is clear.
