  title: CometChat REST Management Auth Tokens Conversations API
  description: Server-side REST Management API (v3) for CometChat in-app messaging. Manages users, authentication tokens, groups, group members, messages, conversations, reactions, roles, friends, blocked and banned users, and webhooks for a CometChat app. The API is scoped to a single app and region; the host is derived from your App ID and the region your app is provisioned in (us, eu, in). All requests authenticate with a Rest API Key (fullAccess scope) passed in the `apikey` header. Realtime delivery to end users is handled separately by the CometChat client SDKs over a managed WebSocket layer and is not part of this REST surface.
