We are currently working on integrating Confluence Data Center with SailPoint for identity governance and access management. While we have identified APIs that allow us to aggregate Users, Groups, and Spaces individually, we have encountered a significant limitation:
There is no available API that links these entities together (e.g., mapping which users belong to which groups and which groups have access to which spaces).
This lack of linkage prevents effective synchronization and governance between Confluence and SailPoint, as we are unable to establish contextual relationships between users, their group memberships, and their access to specific spaces.
