Can't get the response from webhook

Question

I created a webhook using python ( using this example) for my project in api.ai

My code is here :

  #!/usr/bin/env python

import urllib
import json
import os

from flask import Flask
from flask import request
from flask import make_response

# Flask app should start in global layout
app = Flask(__name__)


@app.route('/webhook', methods=['POST'])
def webhook():
req = request.get_json(silent=True, force=True)

print("Request:")
print(json.dumps(req, indent=4))

res = makeWebhookResult(req)

res = json.dumps(res, indent=4)
print(res)
r = make_response(res)
r.headers['Content-Type'] = 'application/json'
return r

def makeWebhookResult(req):
if req.get("result").get("action") != "delivery.info":
    return {}
result = req.get("result")
parameters = result.get("parameters")
parcelnr = parameters.get("parcelnumber")

parcelinfo = {'5000':'your parcel has been shipped', '5001':'your parcel has 
not been shipped', '5002':'should be delivered on three days', '5003':'your 
parcel has not been shipped', '5004':'your parcel has been shipped'}

speech = "Parcel with numner" + parcelnr + " is " + 
str(parcelinfo[parcelnr]) "

print("Response:")
print(speech)

return {
    "speech": speech,
    "displayText": speech,
    #"data": {},
    # "contextOut": [],
    "source": "apiai-debot"
}


if __name__ == '__main__':
port = int(os.getenv('PORT', 5000))

print "Starting app on port %d" % port

app.run(debug=True, port=port, host='0.0.0.0')

Api agent is :

I don't understand where i'm wrong.

My agent work ok, but when i ask the bot to get info from the webhook i get the text response from api.ai not from webhook.

Can you help me please ?

The following is working for me. request.data will be receiving message alerts from the TradingView webhook message.

@app.route('/webhook', methods=['POST'])
def webhook():
    print("\nrequest.data={}".format(request.data))
    return request.data

In TradingView Alert Message, I am using following...

exchange = {{exchange}}, ticker = {{ticker}}, price = {{close}}, volume = {{volume}}

...and I am getting following message in logs:

$ heroku logs --tail

2022-01-12T20:38:00.510006+00:00 app[web.1]: request.data=b'exchange = BINANCE, ticker = BTCUSDT, price = 43671.85, volume = 10.70612'
2022-01-12T20:38:00.510512+00:00 app[web.1]: 10.1.58.75 - - [12/Jan/2022:20:38:00 +0000] "POST /webhook HTTP/1.1" 200 73 "-" "Go-http-client/1.1"

You are using the wrong url for the webhook in the fulfillment.

Your code is mapping the request to /webhook, while your url is https://your-domain.com/debotwebhook.

Either change @app.route('/webhook', methods=['POST']) to @app.route('/debotwebhook', methods=['POST']) or change the url in api.ai to https://your-domain.com/webhook

Also, I see an extra " in your speech variable after str(parcelinfo[parcelnr]).

Here is the agent I tested with your code and on the right you can see the answer:
