## Path parameters

| Parameter | Type | Description |
|---|---|---|
| `session_id` | string | The session, as returned by Create a session. |
| `file_id` | string | The file, as returned by Prepare a file. |

## Headers

| Header | Required | Description |
|---|---|---|
| `Authorization` | yes | `Bearer` plus a short-lived OAuth access token issued for the Tanomis API audience. Backends obtain tokens with an [organization automation client](/guides/run/authenticate-your-backend); the CLI's human login is not an application credential. |
| `X-Organization-ID` | yes | The `organization_id` from the workspace projection you selected in `GET /v1/me/workspaces`. |
| `X-Workspace-Tenant-ID` | yes | The nested `tenant_id` from the same projection. A header cannot widen what the token grants. Some single-workspace or self-hosted environments take `X-Tenant-ID` instead, as supplied by their administrator. |

## Responses

| Status | Meaning |
|---|---|
| `200` | The bytes, with the file's media type. |
| `404` | No such file, or attachments are disabled. |
