Method not found error when trying to call REST API


I am trying to call a rest api through the HTTP Request activity, but every time I try to preview it, I get this error.

However, whenever I just hit OK and run the file, I get a different error that says “ISG_UNSUPPORTED_REST_VERB.” I’d appreciate any help in solving this.

Thanks in advance!

Did you check first the call in Postman?
