Frequently Asked Questions

What is Calendars API and how does it connect to ABC Trainerize?

Calendars API provides programmatic access to calendar data, allowing ABC Trainerize to create, read, update, and delete calendar entries. By connecting to ABC Trainerize you can automate scheduling workflows, keep appointments in sync across systems, and unlock capacity reporting. This integration supports real-time data mapping to maintain up-to-date availability.

Authentication typically relies on a secure API token with the calendars.write scope, enabling calendar creation and updates. Use OAuth or API key management to secure credentials and rotate them regularly. Always limit access to trusted apps and log access events.

Essential endpoints include POST /calendars/ for creation, GET /calendars/:calendarId/free-slots for availability, GET /calendars/ for listing, and PUT /calendars/groups/:groupId to manage groups. These cover creating calendars, checking availability, and organizing calendars into groups.

Calendar groups help organize calendars by teams or services. Use POST to create groups, PUT to update, and DELETE to remove groups. You can also use PUT /calendars/groups/:groupId/status to enable or disable a group’s access.

Yes. Real-time availability data can be surfaced via the free-slots endpoint, allowing users to see and select open times. Ensure your synchronization cadence matches your booking experience for accuracy.

Rate limits depend on your plan and API usage. Monitor quotas and implement retry logic with backoff to handle spikes. Consider caching frequent lookups to reduce API pressure.

Check for invalid identifiers, expired tokens, and incorrect mapping of fields. Review endpoint permissions and verify that the correct scope (calendars.write) is active. Use logs and a test environment to isolate issues.
