Webhooks provide a way to receive real-time notifications when specific events occur in your Composio account. Instead of continuously polling for changes, webhooks push data to your application as events happen, making them ideal for building responsive integrations.

Implement the Webhook Receiver

import json
from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/webhook', methods=['POST'])
def webhook():
    if request.method == 'POST':
        payload = request.json
        print(json.dumps(payload, indent=2))
        return jsonify(success=True), 200
    return jsonify(success=False), 405

if __name__ == '__main__':
    app.run(debug=True, port=5000)
