Hi @Kunal_EFL,

just to clarify your question for me, you want to call a HTTPS endpoint in your IFlow and authenticate via OAuth? How is the HTTPS adapter in your IFlow configured? Is the flag "CSRF Protected" set?

Kind regards, Mathias

For OAuth configuration, follow:

As suggested by Mathias, in case of HTTP Sender, untick CSRF, eliminating this factor.
Check if a message is generated. Sometimes an HTTP 403 can be a relay of receiver response.
