scapes page on UWCSSA
We need a few things:
- a facebook app
- a server running in localhost:8000 accepting request
- background scripting to scrape http://bbs.uwcssa.com/forum-54-1.html
- ngrok that forwards request to localhost:8000
Please see https://abhaykashyap.com/blog/post/tutorial-how-build-facebook-messenger-bot-using-django-ngrok for a detailed guide on setting up a messenger app

- note the address that is forwarding request to localhost:8000 when running
ngrokcommand, e.g. https://7f1ce852.ngrok.io - now you will need to go to your ownfacebook app configuration e.g. https://developers.facebook.com/apps/1234-my-own-app/webhooks/ to set up the new webhook
