# Upload card dispute document

**POST** `/issuing/card-disputes/documents`

Upload a card dispute evidence document with a `Content-Type: multipart/form-data` request containing a `file` and optional `description` and `tag` fields. The `type` field is ignored: documents uploaded here are always `card_dispute_evidence` and are the only ones accepted as `document_id` when adding evidence to a card dispute. The response `url` expires after 60 seconds.

### Body Parameters

- `description` `string`
- `file` `binary` _(required)_ — The file to upload, sent per RFC 2388 `multipart/form-data` protocol.
- `tag` `string`
