- Everything into or out of the group service goes through the API. There is no behind-the-scenes marshaling of groups or members.
- Group membership is of two types: direct and effective. Effective being all direct members plus all effective members of member groups. The difference is important.
- Direct membership is generally the concern when the group is managed.
- Effective membership is generally the concern when the group is referenced--for authorization, mailing lists, etc.
We use PUT to either create or update a group or its membership.
Info There was an interesting email thread on the TIER-API list about this data. See subject "group service api usage statistics", January 29, 2016.
