Notable changes to the Intervals Partner API.

v1.2 — Imagery & live capacity

June 2026
  • Added cardImageUrl and coverImageUrl to event and collection responses — hosted image URLs for cards and hero art.
  • Added registrationCount to each run, alongside maxParticipants — read live sign-ups without a separate call.

v1.1 — Event collections

April 2026
  • Added GET /collections and GET /collections/{slug} — list your branded series (a race series, a grand prix) and fetch one by slug.
  • Added GET /collections/{slug}/events — a collection's member events, in the displayOrder you set.
  • New scope read:collections gates the collection endpoints.

v1 — Initial Release

February 2026
  • 7 endpoints across organization, events, registrations, and recurrences.
  • Scope-based API key authentication — one key, one set of scopes.
  • Cursor-paginated list endpoints — limit plus an opaque after cursor.
  • Idempotent POST requests via Idempotency-Key.
  • Per-credential rate limiting, with Retry-After on 429s.
