How to check if a "group of users" has access to certain "spaces" on confluence via ReST API ?

Aniket

I need to get a List of spaces which are accessible for a group of users using some existing confluence rest api.

example: Consider the groups namely, groupDev, groupTest, groupClient. consider few confluence spaces namely spaceDev, spaceTest, spaceDevTest.

So here, I'm trying to find such an REST API where I pass a "groupName/groupId", and which returns a response containing the list of spaces which that group has access to.

ex: groupDev has access to spaceDev and SpaceDevTest, groupTest has access to spaceTest & spaceDevTest while groupClient has access to none of these spaces.

PS: I'm working on a monitoring tool for JIRA/Confluence, which currently checks user level access for JIRA(projects) and Confluence(spaces)...but this is at user/individual level.
I want to generalise this approach, taking it a step further.
Where the tool will check group level access for projects/spaces instead of individual level access...hence my question.

Haven't found any confluence rest API, or any workaround for this scenario.

I've searched here for confluence rest api's

I wonder if this approach is correct. I hesitate because a user can belong to more than one group and these groups could have different permissions assigned to a specific space.

If you are just checking for permission against one group then you could get a situation where the user is denied access when they actually do have access but via a different group.

I have no idea how you are implementing your project, but it is entirely possible to build your own simple rest endpoint which can do exactly what you want, but care should be taken to check what permission the end user has as a cumulative result of all the groups the user belongs to.
