# Yank a release

> Yank a version: reject new runs, stop resolving as latest. Reversible.

**`POST`** `https://api-datahub.octoparse.com/v1/data-apps/{app_id}/releases/{version}/yank`

Authentication: API key required (`Authorization: Bearer <API Key>`). App author only; others get `404`.

Version-level yank: this version rejects new runs (`422 version-yanked`) and is skipped when resolving latest. In-flight runs are unaffected. Detail and contract pinned to this version remain readable (callers need them for troubleshooting). No rows are deleted; builds and the audit chain stay put. Restore with the paired unyank endpoint.

## Request

### Path parameters

<ParamField path="app_id" type="string" required>
  App reference.
</ParamField>

<ParamField path="version" type="string" required>

```
