# API versions

> Every dated version of the Partner API and its lifecycle status.

Each row is a version you can pin with the `Clemta-Version` header. See [Versioning](/partner/versioning) for how pinning works and the [Changelog](/partner/changelog) for what changed in each.

A deprecated version keeps answering until its sunset date, and every response on it carries `Deprecation` and `Sunset` headers, so the schedule is visible from traffic alone. Move to the successor version before the sunset date.

| Version      | Status  | Deprecated | Sunset | Successor |
| ------------ | ------- | ---------- | ------ | --------- |
| `2026-08-13` | Current | -          | -      | -         |
