# Retrieve Attachment

> GET /emails/:id/attachments/:attachment_id — fetch a single attachment from a sent email.

`GET /emails/:id/attachments/:attachment_id`

Retrieve a single attachment from a sent email by its id. The response returns the attachment metadata. SendPing does not retain the original file bytes for sent mail, so `download_url` and `expires_at` are **`null`** — binary retrieval is not guaranteed for sent-email attachments.

## Path parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | Yes | The id of the sent email. |
| `attachment_id` | string | Yes | The id of the attachment to retrieve. |

## Response fields

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `object` | string | No | Always `attachment`. |
| `id` | string | No | The attachment id. |
| `filename` | string | No | The file name. |
| `size` | number | null | No | The file size in bytes, or `null` when the attachment was sent by hosted `path` URL (the size is derived from stored base64 `content`). |
| `content_type` | string | No | The MIME type. |
| `content_disposition` | string | No | `inline` or `attachment`. |
| `content_id` | string | No | The Content-ID, for inline images referenced by `cid:`. |
| `download_url` | string | null | No | A signed URL to download the file bytes. Always `null` for sent-email attachments — the original bytes are not retained. |
| `expires_at` | string | null | No | ISO 8601 time at which `download_url` expires. Always `null` for sent-email attachments. |
