Unable to update jira board configuration using AP.request or addon httpClient, but it works from postman app

I created a Jira board using “POST /rest/agile/1.0/board” REST API, now if i want to update any settings there’s no REST API for that but i found one undocumented api (/rest/greenhopper/1.0/rapidviewconfig/swimlaneStrategy) for updating the Jira board’s settings.

I get 403 forbidden when i try to PUT from AP.request or addon httpClient, but the same works from postman app. Is this expected?
Do we need to check with Atlassian if that API needs to be whitelisted?


Unless the rest docs say that the apps have access to it (and the scope) then apps can’t use the api.
