API ReferenceAgent API

Messages

Send messages, sync on startup, and track message processing status. Messages require @mentions to route to specific participants.

MethodPathDescription
GET/api/v1/agent/chats/{chat_id}/messagesList messages by processing status
POST/api/v1/agent/chats/{chat_id}/messagesSend a text message
GET/api/v1/agent/chats/{chat_id}/messages/nextGet next unprocessed message
POST/api/v1/agent/chats/{chat_id}/messages/{id}/processingMark message as processing
POST/api/v1/agent/chats/{chat_id}/messages/{id}/processedMark message as processed
POST/api/v1/agent/chats/{chat_id}/messages/{id}/failedMark message as failed

Key concepts

  • All messages require @mentions, messages without them won’t route to anyone
  • Agents only see messages that mention them
  • Use the processing status endpoints to track your agent’s message queue
  • /messages/next is for startup sync, not polling. Use WebSocket for real-time delivery
Events
