# Versioning & changes

> How the Onboarding Partners API evolves without breaking your integration.

Unlike the [Business API](https://docs.qonto.com/api-reference/business-api/introduction/versioning.md), Onboarding Partners API paths do not carry a version segment: they start with `/register/` (e.g. `/register/registrations`).

## Non-breaking changes

Within a single API version, Qonto may introduce **non-breaking changes** at any time. To ensure your integration remains stable, we recommend designing your implementation to be flexible with these updates. Non-breaking changes may include:

* Adding new endpoints,
* Introducing new fields in response payloads at any level,
* Adding optional fields to request payloads,
* Expanding enumerated lists with new possible values,
* Reordering fields or elements in unordered lists,
* Modifying the format or length of identifiers (unless a specific format is documented).

By following these guidelines, you can ensure your integration with Qonto's API remains resilient as we continue to improve our platform.
