Triggers Example

This example demonstrates how to use Composio SDK for triggers.

Setup

1. Install dependencies:

   pnpm install
   

2. Configure environment:

   cp .env.example .env
   

   Then edit .env and add your API keys:

   • COMPOSIO_API_KEY: Get it from Composio Dashboard
   • COMPOSIO_WEBHOOK_SECRET: Get it from your webhook configuration in Composio Dashboard

Running the Examples

Trigger Subscription (WebSocket)

# Run the subscription example
pnpm start

# Run in development mode (with file watching)
pnpm dev

Webhook Server (HTTP)

# Start the webhook verification server
pnpm webhook:server

# Then expose it with telebit (https://telebit.cloud/)
telebit http 3000

What This Example Does

src/index.ts - Trigger Subscription

• Initializes Composio SDK
• Subscribes to triggers via WebSocket
• Receives real-time trigger events

src/webhook-server.ts - Webhook Verification

• Starts a Bun HTTP server on port 3000
• Verifies incoming webhook signatures using the new verifyWebhook API
• Supports V1, V2, and V3 webhook payload formats
• Returns normalized trigger events

Webhook Headers

When receiving webhooks, the following headers are used:

• webhook-id: Unique message ID (format: msg_xxx)
• webhook-timestamp: Unix timestamp in seconds
• webhook-signature: Signature in format v1,base64EncodedSignature

Customization

Edit src/index.ts or src/webhook-server.ts to:

• Add specific apps you want to integrate with
• Implement your business logic
• Add error handling and logging
