What are Channels?

Channels are the messaging platforms that your agents connect to. Each channel provides a bridge between your users and the AI agent.

​
Per-Agent Channels

Each agent can have its own channel connections. This means:
  • Agent A can be connected to WhatsApp Account 1
  • Agent B can be connected to WhatsApp Account 2
  • Both agents can share the same Telegram bot, routed via bindings

​
Media Support

Channels support media attachments: Inbound: Images, audio, video, and documents are received and stored as temp files. Audio is automatically transcribed. Outbound: Agents can send media by including MEDIA:<path-or-url> in their response.
