Changelog
API versions and notable changes.
What you can build
- Sync your membership administration (bulk create, update and archive members).
- Publish the club calendar or training schedule on your own website.
- Feed attendance from your own check-in kiosk or door system.
- Manage competition teams from an external league tool.
Server-to-server only. API keys are secrets. The API deliberately sends no CORS headers, so calls belong in your backend — never in a browser or mobile app that ships the key to users.
