# Remove a brand document

`DELETE /api/v1/sms/brands/{id}/documents/{documentId}`

Remove a document from the brand. Its file is deleted, unless a registration sent it to a regulator (`file_kept`: kept as the record of what they received). Refused (`409 conflict`) while a Sender ID registration that sent it is under review. Requires the `sms:manage` capability.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `id` | path | string | yes | — |
| `documentId` | path | string | yes | — |
