Best When
Your organization already uses self-hosted Rocket.Chat and you want to build bots or automation integrations that participate in team conversations.
Avoid When
Your team uses Slack, Teams, or Mattermost — use native APIs for those platforms instead.
Use Cases
- • Building AI bots that respond to team messages or commands in self-hosted Rocket.Chat
- • Sending automated notifications and alerts to team channels from agent workflows
- • Integrating with external services via Rocket.Chat's webhook and integration system
- • User and channel management automation for large team deployments
- • Omnichannel customer support where agents interact via API on behalf of human teams
Not For
- • Organizations not already using Rocket.Chat — switching costs are high
- • Consumer messaging applications (not designed for public-facing chat)
- • Scenarios requiring cloud-managed SaaS without any server management
- • Real-time audio/video at enterprise scale
Interface

Pricing
Fully featured open-source version free to self-host. Cloud managed version available. Enterprise adds compliance, unlimited push notifications, and priority support.
Agent Metadata
Known Gotchas
- ⚠ Two-part authentication (authToken + userId) is unusual — both must be present in every request
- ⚠ Self-hosted deployment means API URL varies — agents need to know the deployment URL
- ⚠ Bot users should use personal access tokens, not username/password login which creates sessions
- ⚠ Message format uses markdown-like syntax; rich message formatting uses attachments object
- ⚠ WebSocket (realtime API) uses a different DDP protocol, not REST — requires separate client
- ⚠ Rate limiting configuration is server-side — behavior differs between self-hosted instances
- ⚠ Webhook incoming integrations use a separate script-based system, not standard REST payload format
