Changelog

What changed in the API, newest first. Additions arrive without notice; removing or renaming something is announced here 90 days ahead, and the old name keeps working until that date (see versioning).

November 2026

November 11: /v1 becomes a stable contract: what does not change, what can arrive without notice and what needs 90 days of notice are in versioning. The reasons in missing of cannot_publish are documented in errors, including paid_sales_off, for organizers that do not sell paid items yet.

First version of /v1: API keys with scopes, events with their days, program, ticket types and batches, courses, orders and complimentary tickets, participants, check-ins by day, certificates by kind, coupons, webhooks and the public resources.
