This API allows you to retrieve the menus that were chosen on Boonli.
To get the menu information run:
> boonli_api/api.py -c <customer_id> -u <username> -p <password>
Where customer_id is the first part of the domain name where you login, like my_school in https://myschool.boonli.com.
To enable a lot of debug logging you can add -v.
I have also created an API that can be deployed on Google Cloud Function that returns the menus as an iCalendar here: https://github.com/beaufour/boonli_calendar
Boonli does not have an official API, so I reverse engineered it. It involves parsing two web pages which is always fragile. So it will probably break at some point.
