I am totally new to sap , I am currently integrating solman 7.2 to servicenow using rfc (http to external server) using a listener on a specific port.
Through the listener us reachable , I am getting 400 bad request error when I configure the API in rfc (host name - Listener host, port and API path prefix ) .
The same rest API works from other test interfaces like ..postman and Powershell ise however it's failing here.
I have not been able to find the root cause for this.
Could you please guide me how to investigate further and what could be the possibilly be the reason for this issue.
