Webhook validation Python Error: "POST / HTTP/1.1" 404 -

Hi, I can’t set up a webhook.
I use code from here:

from flask import Flask, request, abort, jsonify

app = Flask(__name__)

@app.route('/webhook', methods=['POST'])
def webhook():
    if request.method == 'POST':
        data = request.get_json()
        challenge = data['challenge']

        return jsonify({'challenge': challenge})

        # print(request.json)
        # return 'success', 200

if __name__ == '__main__':

But it didnt work.
For url generation i use ngrok.
I see challenges in ngrok:

    "challenge": "UEkR7-4VSXqp34ve39ghi8qLJew1qsjEI69Y2TLfvuq6SDAEJ-z88gZHHW3yPBHSV9HfwGOeLlAOwlp7qzAIUQ"

But ngrok terminal:

And python terminal:

 * Serving Flask app 'app'

What am I doing wrong?

Hello there @SVK,

I do not have experience with Python but is the endpoint being called? Do you have the URL set as https://www.yourngrokendpoint.com/webhook and whenever the trigger gets triggered, does your @app.route(‘/webhook’, methods=[‘POST’]) endpoint get called?

If so, please send us an email to appsupport@monday.com with as much information as possible and we will take a look with you :grin:
