Example Flask app showing how to handle a webhook with an asynchronous task using threading, returning a 200 response immediately.

flask_async_webhook_thread.py

from flask import Flask, request
from threading import Thread

app = Flask(__name__)

def async_task(data):
    # Your async operation here, e.g., process data
    pass

@app.route('/webhook', methods=['POST'])
def webhook():
    data = request.json
    # Run async_task in a separate thread
    Thread(target=async_task, args=(data,)).start()
    # Immediately return a 200 response to the webhook source
    return 'OK', 200

    app.run(debug=True)
