SendbirdSendbird Chat Platform server-side API v3

PUT/v3/users/{user_id}/count_preference/{channel_url}

Update count preference of a channel

Updates a user's count preference for a specific group channel identified by channel_url, choosing whether to track the number of unread messages, unread mentioned messages, or both.

Manage users, group channels, open channels, messages, metadata, moderation, bots, and announcements through the official Sendbird Chat Platform API v3. The complete boundary is the 83 REST endpoints reconstructed from a pinned official generated SDK revision; client realtime protocols and Chat SDKs are not part of this collection. Application data is the caller's private content, so Pontx does not proxy, cache, or aggregate it and callers use the local SDK/CLI directly.
