# Delete a media library file

`POST https://YOUR-NETWORK-DOMAIN/rest-api/media-library/assets/{assetId}/delete.do`

Removes the file from the library and from the creative editor's picker. Creatives already using it keep serving it: the stored file is erased only once no live creative uses it any more. 'usedIn' is the number of live creatives still serving it. A user with shared advertisers may delete only files uploaded for one of their advertisers. Requires the MEDIA_LIBRARY permission and update rights on campaigns.

## Path params

| Name | Type | Required | Example | Description |
|---|---|---|---|---|
| `assetId` | integer | yes | `42` | Media library file id |

## Responses

- `200` — {success, assetId, usedIn}
- `400` — Bad request — invalid or missing parameters
- `401` — Authentication error
- `403` — The role lacks MEDIA_LIBRARY or campaign update rights, or no rights on the file's advertiser
- `404` — No such file, it is already deleted, or the user cannot see it

## Example request

```bash
curl --request POST \
  --url 'https://YOUR-NETWORK-DOMAIN/rest-api/media-library/assets/42/delete.do' \
  --header 'X-Api-Key: YOUR_API_KEY'
