Changelog

Version history of R2 Connect API and our compatibility policy.

Reservation life cycle · August 2026#

New reservation.updated and reservation.cancelled events: you no longer need to re-read reservations to learn about a date change or a cancellation. Reservation events now also include check_in, guests and updated_at.

Webhooks · July 2026#

Added signed outbound webhooks: R2 notifies your system in near real time when a reservation or order is created, or a payment is collected, with HMAC signing and automatic retries.

v1 · July 2026#

First public release. Read access to account, reservations, orders, payments, customers and catalog, with per-resource scopes, cursor pagination and per-key limits.

Compatibility#

Within the same major version we commit to the following:

• We do not remove fields from a response nor change their meaning.
• We do not change the type of an existing field.
• We may add new fields: your integration must ignore the ones it does not know.
• We may add resources and optional parameters.
• Existing error codes keep their meaning.
