API documentation

Koala has an API endpoint for a few applications; radio, zuil, and checkout, but there are many more possibilities. This documentation describes the possible routes and responses divided in; members, groups, activities, participants, and checkout.

Members

Groups

Activities

Activities are used by radio and the zuil and radio also shows commercials of companies. These routes are publically available, however authenticating with the activity-read rights gives you more information about the activities.

Participant

Checkout

All checkout endpoints require a secret called token declared in the configuration of .env. A generic response because of this would be a forbidden response meaning that the secret does not correspond with the secret of koala.
