Changelog

What changed in the API, newest first. Within a version we only add things; a breaking change would be a new version, announced here well before the old one is retired.

Version 1.0 · 27 October 2026

The first release of the Waca API.

Rentals: search (filters, sorting, paging), a car’s calendar, classes, extras and covers, quotes, bookings (create, list, get, update, cancel, check-in), with flight numbers and your own metadata.
Sales: search cars for sale, reserve with a deposit, list and follow orders through escrow.
Money: /balance, /commissions and /payouts.
Events and webhooks: /events (always recorded), signed Standard Webhooks with retries and pausing, and webhook management by API key.
Your fleet: add cars, photos and papers, open rental periods and list cars for sale.
Sandbox: test keys and simulators for bookings and purchases.
Platform: request ids on every response, RateLimit-* headers, idempotency keys, and an OpenAPI 3.1 description at /api/v1/openapi.json.
