I put together a reverse proxy using mitmproxy, so that with a single webhook I can route my published data to different endpoints.
I wanted to share the code with the community, in case anyone else finds it to be useful.
GitHub repo here, including a Procfile that works on heroku.
In my particular case I am using it as a data service to store sensor data in firebase.
You can easily modify the code to forward your data wherever you want.
The documentation is a bit sparse, if anybody has questions please ask.
