# Versioning

How FiscalRail versions the API and retires older versions.

The current API version is `v1`, and every endpoint is available below `/v1/`.

We may expand existing resources, add endpoints and make other backwards-compatible changes without changing the API version. Integrations should ignore response fields they do not recognize and should not rely on object property order.

Breaking changes will be released under a new version number. When a new version replaces an older one, the older version will remain supported for at least three months before it is deprecated. We will publish migration guidance before support ends.
