How to query MoveIssueLink.jspa via AP.request


I have a serverless cloud app (i.e. I don’t have a backend to perform JWT requests) which queries JIRA via AP.requests. I need to reorder subtasks, for which there is no official REST resource (unlike server where there is the /rest/api/2/issue/{issueIdOrKey}/subtask/move resource), so I’m trying to query the /secure/MoveIssueLink.jspa rest. However, when executing the query via AP.request the server responds with 403 status. When I execute the same request via a rest client (e.g. chrome advanced rest client) everything is fine and 200 is returned. Is there any additional security which AP enforces for non-official rest resources?
