# Download the signed PDF

> GET /v1/signatures/:id/download — stream the archived, signed PDF (authenticated only).

<Info>**GET** `https://api.craftkit.dev/v1/signatures/:id/download`</Info>

Streams the archived signed PDF. The signed document is a sensitive legal artifact, so it is served
**only** through the authenticated API (streamed from storage) — it is never reachable from a public
bucket URL or a provider-hosted link. Returns `409` until the document has been archived (until
`signedDownloadUrl` is non-null on the request).

## Authorization

<ParamField header="Authorization" type="string" required>
  `Bearer ck_live_…` — a project API key.
</ParamField>

## Path parameters

<ParamField path="id" type="string" required>The signature request id (UUID).</ParamField>

## Response

On success, the signed PDF bytes with `Content-Type: application/pdf`, served as an attachment named
`<id>-signed.pdf`.

<ResponseField name="(binary)" type="application/pdf">The signed PDF stream.</ResponseField>
