# Versioning and Upgrading

When backwards-incompatible changes are released, a new, dated version is released.
The current version is V5. You can upgrade the version of the api that your
account uses within your [merchant settings](https://app.resolvepay.com/dashboard/integrations).

Legacy (v2) API documentation may be found [here](https://app.resolvepay.com/docs/api/v2).
