App Connectors — Connect Your Agent to 1000+ Apps

Connect your AI agent to Gmail, Slack, GitHub, Notion, Google Calendar, LinkedIn, HubSpot, Stripe, and 1000+ more apps via Composio OAuth.

Setup

On first use, check credentials:

# Check environment variables
[ -n "$COMPOSIO_API_KEY" ] && echo "✅ API key" || echo "⏳ Not set"

Required:

• COMPOSIO_API_KEY — Project-scoped API key from Composio

If not in env, check the framework's secrets provider (vault, secrets.json, .env). If missing, stop and report to the operator.

API Reference

Base URL: https://backend.composio.dev/api Auth header: x-api-key: $COMPOSIO_API_KEY

List Connected Apps

Use the v1 REST API to get all active connections for the current entity:

curl -s "https://backend.composio.dev/api/v1/connectedAccounts?user_uuid=default&showActiveOnly=true" \
  -H "x-api-key: $COMPOSIO_API_KEY"

Returns { "items": [...] } — each item has appName, status, id.

Discover Tools (COMPOSIO_SEARCH_TOOLS)

Find the right tool for a task. Returns matching tools, schemas, connection status, and execution plan.

curl -s -X POST "https://backend.composio.dev/api/v3/tools/execute/COMPOSIO_SEARCH_TOOLS" \
  -H "x-api-key: $COMPOSIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "arguments": {
      "queries": [
        {
          "use_case": "send an email via gmail",
          "known_fields": "recipient_name: John"
        }
      ],
      "session": { "generate_id": true }
    }
  }'

Key fields in response:

• primary_tool_slugs — best matching tools
• tool_schemas — input schemas for each tool
• toolkit_connection_statuses — whether there's an active connection
• known_pitfalls — common mistakes to avoid

Rules:

• 1 query = 1 tool action (max 7 queries per call)
• Include the app name in the query when the user specifies one
• Reuse session.id from the first response in subsequent calls

Connect an App (COMPOSIO_MANAGE_CONNECTIONS)

If has_active_connection is false, or the user wants to connect a new app:

curl -s -X POST "https://backend.composio.dev/api/v3/tools/execute/COMPOSIO_MANAGE_CONNECTIONS" \
  -H "x-api-key: $COMPOSIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "arguments": {
      "toolkits": ["gmail"]
    }
  }'

Response statuses:

• active — ready to use, no action needed
• initiated — returns redirect_url → send to user to complete OAuth
• failed — error (often: wrong toolkit slug)

Common toolkit slugs: gmail, outlook, slack, github, notion, clickup, linkedin, googlecalendar, googledrive, googlesheets, jira, trello, hubspot, figma, discord, airtable, stripe, youtube, calendly, supabase, asana, dropbox, twitter

Note: slugs are lowercase, no underscores (e.g. googlecalendar not google_calendar).

Execute Tools (COMPOSIO_MULTI_EXECUTE_TOOL)

Only after connection is active:

curl -s -X POST "https://backend.composio.dev/api/v3/tools/execute/COMPOSIO_MULTI_EXECUTE_TOOL" \
  -H "x-api-key: $COMPOSIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "arguments": {
      "tools": [
        {
          "tool_slug": "GMAIL_SEND_EMAIL",
          "arguments": {
            "to": "[email protected]",
            "subject": "Hello",
            "body": "Welcome!"
          }
        }
      ],
      "sync_response_to_workbench": false
    }
  }'

Rules:

• Never invent tool slugs or argument fields — only use what SEARCH_TOOLS returned
• Batch independent tools in a single call (max 50)
• Verify connection is active before executing

Get Full Schemas (COMPOSIO_GET_TOOL_SCHEMAS)

When SEARCH_TOOLS returns a schemaRef instead of full input_schema:

curl -s -X POST "https://backend.composio.dev/api/v3/tools/execute/COMPOSIO_GET_TOOL_SCHEMAS" \
  -H "x-api-key: $COMPOSIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "arguments": {
      "tool_slugs": ["GMAIL_SEND_EMAIL"]
    }
  }'

/apps Command

When the user types /apps:

1. List connected apps using the v1 REST API (/v1/connectedAccounts?user_uuid=default&showActiveOnly=true)
2. Display as a clean list — one line per app, 🟢 prefix, human-readable name:

   🟢 Gmail
   🟢 LinkedIn
   🟢 ClickUp
   🟢 Notion
   

   If none connected: "No apps connected yet."
3. End with a prompt: "To connect a new app, type its name."
4. When the user types an app name, call COMPOSIO_MANAGE_CONNECTIONS with the matching slug, get the redirect_url, and send it as a clickable link.

Display name mapping (slug → display): gmail → Gmail, outlook → Outlook, googlecalendar → Google Calendar, googledrive → Google Drive, googlesheets → Google Sheets, linkedin → LinkedIn, notion → Notion, clickup → ClickUp, slack → Slack, github → GitHub, jira → Jira, trello → Trello, hubspot → HubSpot, figma → Figma, discord → Discord, airtable → Airtable, stripe → Stripe, youtube → YouTube, calendly → Calendly, supabase → Supabase, asana → Asana, dropbox → Dropbox, twitter → Twitter/X, shopify → Shopify

For unknown slugs, capitalize the first letter.
