JIra Advanced Roadmap Rest API


I wanted to ask if there is a possibility to retrieve Advanced Roadmap Hierarchy information using Rest API within a connect app.

I was able to identify the following endpoint: /rest/jpo/1.0/info/query
is used by Jira but I could not find any documentation and when I tried to use it inside plugin I got 403 (caused by ap-client-key header) so I assume apps can’t access this resource.

Is there currently any way to retrieve this data?

We searched for the same thing but couldn’t find a way to get it.

@KamilParzyjaga and @emre.toptanci,

I confirm there are no published APIs for the roadmap features.

I know the thread about Deprecation of the Epic Link, Parent Link and other related fields in REST APIs and webhooks is long; however, it seems to indicate an intent to pull the necessary APIs into the Jira Platform, rather than to have a separate set. The parent fields is proof the team is working in that direction, albeit slowly.
