pyTelegramBotAPI + webhooks + Azure Function

__init.py__

# Using Azure Functions as webhook for serverless telegram bots.
# (Thanks to twitter.com/masyan for the idea)

# By default the Azure Functions url is https://.../api/HttpTrigger for HttpTrigger type.
# In this example we will use clear webhook url without /api/ -> https://.../HttpTrigger.
# Also we set "authLevel": "anonymous".

# For HttpTrigger type set "route" and "authLevel" in functions.json
# {
#   "bindings": [
#   ...
#   "authLevel": "anonymous"
#   "route": "HttpTrigger"
#   ]
# }

# To avoid using /api/ in url set "routePrefix":"" in host.json
# {
#   ...
#   "extensions": {
#     "http": {
#       "routePrefix": ""
#     }
#   }
# }
