# Set artifact retention

> Set how many days the repository keeps artifacts by default, and at most: days, from 1 to 90.

<div class="g1t-endpoint"><span class="g1t-method" data-method="put">PUT</span><code>/repos/{owner}/{name}/actions/permissions/artifact-and-log-retention</code></div>

Artifacts already uploaded keep the expiry they were given. Needs the Maintain role.

Only artifacts uploaded afterwards are kept the new number of days. A workflow's `retention-days` asks for fewer, never more.

- **Authentication:** Required. Send an [access token](/reference/api/#authentication) as `Authorization: Bearer`.
- **MCP tool:** [`workflow`](/reference/mcp/#workflow) with `action` `set_artifact_retention`, and the same inputs
- **Scope:** An access token needs [`workflows:write`](/guides/authentication/#scopes).

## Errors

A failed request answers with one of these statuses and a body like `{"error": {"code": "not_found", "message": "Repository not found."}}`. See [errors](/reference/api/#errors).

| Status | Code | When |
| --- | --- | --- |
| 401 | `unauthenticated` | A token is required, or the one sent is not valid. |
| 403 | `forbidden` | The token is valid but not allowed to do this, such as a member-only change or an agent token outside its repository. |
| 404 | `not_found` | It does not exist, or you cannot see it. |
| 409 | `conflict` | The request conflicts with the current state. |
| 422 | `invalid` | The input is not valid. `message` says which field and why. |
