Composio — External App Integration via Gateway
Composio lets users connect 1000+ external apps (Gmail, Slack, GitHub, Google Calendar, Notion, etc.) to their Starchild agent. All operations go through the Composio Gateway (composio-gateway.fly.dev), which handles auth and API key management.
Architecture
Agent (Fly 6PN network)
↓ HTTP (auto-authenticated by IPv6)
Composio Gateway (composio-gateway.fly.dev)
↓ Composio SDK
Composio Cloud → Target API (Gmail, Slack, etc.)
- You never touch the COMPOSIO_API_KEY — the gateway holds it
- You never call Composio SDK directly — use the gateway HTTP API
- Authentication is automatic — your Fly 6PN IPv6 resolves to a user_id via the billing DB
- No env vars needed — the gateway is always accessible from any agent container
