Python:Webhook POST message to Local Host listener Application

Requirements: Python 3.7 I have a website where i can put url in the webhook options[Option Box] provided by that [login to view URL] i put the URL link the website start sending the JSON format message in certain interval lets say async time of 5 10 20min once. I want a python program which will listen to this "webhook POST message" (POST message will be done by the [login to view URL] website) using the localhost port mechanism. (Note local host should be able to listen to the webhook message and python should read the data from this localhost or from designated port ) The idea is, the interface should be free not monthly price based so somehow the python program need bridge webhook post message data to localhost processing. Tried ngrok for routing the webhook POST to python however the URL of ngrok changes every 8hrs so i have to put this URL in [login to view URL] everytime it changes to reroute the data to local host which i do not want .I want a permanent solution where the link will be permanent and user not wanted to change the link [login to view URL] not try any paid plans for the port forwarding ,i wish to get the free one which will do this job as i am planning to run this in my local system always(firewall blocker should not be there). Exploring [login to view URL] ([login to view URL]) .My requirement is listen to the Webhook POST message in local host and parse the JSON data in python. the Jason date can be very [login to view URL] can provide your option which does the same but with anyother method also fine.
