I made and echo bot on AWS with Python and serverless.
I keep getting the same request again and again.
I read the faq where it says u have to deliver a status code 200 else it will keep retrying the webhook.
I'm not sure How I do this.
I have noticed that the sequence number is always the same for the calls so I assume the reply I sent was not acknowledged.
my code is here
import os
import json
import requests
import random
from datetime import datetime

I have given the status code 200 in soo many places and I'm not sure y I still keep getting the same problem.
