Gmail via Composio

Environment

bash
COMPOSIO_API_KEY      # API key
COMPOSIO_USER_ID      # Entity ID (required for all requests)
COMPOSIO_CONNECTIONS  # JSON with .gmail connection ID

Core Pattern

bash
CONNECTION_ID=$(echo $COMPOSIO_CONNECTIONS | jq -r '.gmail')

curl -s "https://backend.composio.dev/api/v3/tools/execute/ACTION_NAME" \
  -H "x-api-key: $COMPOSIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "connected_account_id": "'$CONNECTION_ID'",
    "entity_id": "'$COMPOSIO_USER_ID'",
    "arguments": {}
  }' | jq '.data'

Quick Start

IMPORTANT: Choose the right action!
  • User says "draft" or "prepare" → Use 
    GMAIL_CREATE_DRAFT
    (saves to Drafts folder)
  • User says "send" → Use 
    GMAIL_SEND_EMAIL
    (sends immediately)
bash
# CREATE DRAFT (saves to Drafts folder for user to review/send)
curl -s "https://backend.composio.dev/api/v3/tools/execute/GMAIL_CREATE_DRAFT" \
  -H "x-api-key: $COMPOSIO_API_KEY" -H "Content-Type: application/json" \
  -d '{
    "connected_account_id": "'$CONNECTION_ID'",
    "entity_id": "'$COMPOSIO_USER_ID'",
    "arguments": {
      "to": "recipient@example.com",
      "subject": "Subject line",
      "body": "Email body text"
    }
  }' | jq

# SEND EMAIL (sends immediately - always include agent tag)
curl -s "https://backend.composio.dev/api/v3/tools/execute/GMAIL_SEND_EMAIL" \
  -H "x-api-key: $COMPOSIO_API_KEY" -H "Content-Type: application/json" \
  -d '{
    "connected_account_id": "'$CONNECTION_ID'",
    "entity_id": "'$COMPOSIO_USER_ID'",
    "arguments": {
      "to": "recipient@example.com",
      "subject": "Subject line",
      "body": "Email body text\n\n--\nSent by '"$AGENT_NAME"'"
    }
  }' | jq

curl -s "https://backend.composio.dev/api/v3/tools/execute/GMAIL_LIST_MESSAGES" \
