R2 Connect API
Changelog
Version history of R2 Connect API and our compatibility policy.
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.
What is next
We are working on signed notifications so your system learns about changes the moment they happen, without polling; and after that on writes, so you can create records in R2. If your integration needs either, tell us your case: we prioritize with real cases.
