# Publisher Source Audio Attach

`POST /v1/publisher/{tenant_slug}/source-audio/attach`

## Request

- Base URL: `https://api.storyflo.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.storyflo.com/v1/publisher/{tenant_slug}/source-audio/attach`
- Auth: none declared

Attach a finished upload to one episode and mark it live.

Verifies the object EXISTS via head_object before touching the
database — an episode is never marked live on the client's word
alone. Idempotent: re-attaching the same key to the same episode
updates in place rather than minting a second asset.

## Path parameters

- `tenant_slug` string, required

## Headers

- `x-storyflo-publisher-token` string, nullable

## Request body

- object

## Response `200`

Successful Response

- object

## Other responses

- `422`: Validation Error
