# Collections | AudioDN Docs

> API endpoints for creating, updating, listing, and deleting audio collections in AudioDN. Organize tracks into albums, playlists, or folders.

# Collections

Collections are containers for organizing your audio tracks. You can create, update, retrieve, and delete collection information.

Responses include two read-only companions to `player_color`: `player_color_light` (adjusted to stay legible on a light background) and `player_color_dark` (adjusted for a dark background). They are derived from `player_color` by shifting brightness until each meets a minimum contrast, and cannot be set directly.

DELETE `/v1/collection/:collection_id`

Soft-deletes a collection and cascades to its tracks

#### Parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `collection_id` | uuid | Required | The ID of the collection to delete (path parameter) |

Deleting a collection **cascades**: every track in it is soft-deleted, together with each track's variants and files. The removed files are queued for deletion from R2 storage.

#### Example Request

    

```
curl -X DELETE "https://api.audiodelivery.net/v1/collection/COLLECTION_ID" \
  -H "Authorization: Bearer YOUR_API_KEY"
```

```
const response = await fetch('https://api.audiodelivery.net/v1/collection/COLLECTION_ID', {
  method: 'DELETE',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY'
  }
});

const data = await response.json();
