Chat SDK now supports reactions and ephemeral messages on Teams

UpdateVerifiedAdded Sep 22, 2026

Chat SDK's Microsoft Teams adapter now supports reactions and ephemeral messages through the same API as other adapters. Bots can add and remove reactions on Teams messages, and call thread.postEphemeral() or channel.postEphemeral() to send native, targeted messages that only the intended user sees, like permission prompts.
