We’re pleased to announce the general availability of team membership APIs in the Microsoft Graph v1.0 endpoint.
Previously, adding members to a team required using groups APIs (POST /groups/{id}/members/$ref). While the majority of operations reflected in Microsoft Teams immediately, sometimes member additions and removals took as long as 48 hours to appear. The new APIs allow you to list members, add and remove members, and change members’ roles (for example, from owner to non-owner) and are designed with latency and reliability in mind.
We encourage everyone to switch their member addition/removal logic over to this new API. We look forward to seeing what you build!
