I am getting http 404 unknown Operation some time. I checked in community I am not getting what is exact reason. could you please help me.
Thanks, Suman Anisetty.
Are you using API component for web services or is it just a simple Web Service?
I assume you are using simple web service.
I see the operation as upsertXXXX, so it should be Post operation. If you are testing the URL in the Web browser, it will be always GET by default, which is not correct. Please test that in Postman with Post operation.
