You are using the wrong HTTP method. If you perform an HTTP GET to /services/data/v48.0/sobjects/ContentVersion, you will obtain the response body shown.

This is the sObject Basic Information endpoint. To create a record, you should be using POST.

  • I Tried with Post method ,the provided response I experienced in POST method response only. Can you pls try and let me know whether it is working for you or not.Is there any configuration I need to do?

  • I don't use Postman, but my experience is that making an invalid POST request gets you a completely different error.

When I had the same issue, it turns out that I was pointing to the wrong endpoint url.

My initial (wrong) url endpoint was https://{instance}.lightning.force.com/services/data/...

when it should have been


Unfortunately instead of getting a not found error, I got the object description returned.
