Trying to test a script using postman for the first time... getting 403 error, can somebody help what I'm doing wrong? Steps I've taken are: Deployed Restlet script and have the external URL Created integration called Test - TBA ticked and tba issue endpoint My access tokens and create access tokens for the test application Postman New - Post - added restlet url authorisation - OAuth 1.0 authorisation data - request headers sign method - hmac sha 256 added consumer key, secret, access token and secret version 1.0 realm: accountid_sb1 (testing using sb1) whilst script itself has accountid-sb1 went to headers and added Content-Type application/json what am I doing wrong? (using admin role)
