# Versioning — Vitrify IVF Software API

> Source: https://www.vitrifysoftware.com/api-docs/docs/versioning/

> API in active development. Conventions on this page are stable; the endpoint reference and exact values marked “at launch” are published when the API ships.

The API is versioned in the URL path. The first stable version is v1, and every request is made under that prefix:

```
https://<host-issued-at-launch>/v1/
```

## How changes ship

- Backward-compatible additions (new fields or endpoints) are made within the current version.
- Breaking changes ship as a new version under a new prefix, so existing integrations keep working.
- A deprecation policy and notice period are published with the endpoint reference at launch.
