Create a group channel

Creates a group channel for 1-to-1 or 1-to-N conversations, supporting up to 100 members by default and tens of thousands in Supergroup channels. Channels can be private (invite-only) or public, and support typing indicators, unread counts, and read receipts; a single user can join up to 2,000 group channels.

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.
