# Get a temporary download URL for one file

`GET /voice/collections/{collection_id}/files/download-url`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/voice/collections/{collection_id}/files/download-url`
- Auth: HTTP bearer

Return a PRE-SIGNED URL for the file. This does not return the file.

Named `download-url` rather than `download` for exactly that reason: the
knowledge-base route that really does stream bytes is deliberately not
published, and two routes called `download` that behave differently would
be worse than either.

## Path parameters

- `collection_id` integer, required: Collection id.

## Query parameters

- `filename` string, required: File name within the collection.
- `folder_path` string: Folder inside the collection. Empty is the root.
- `expiration` integer: How long the URL stays valid, in seconds.

## Headers

- `Authorization` string, nullable
- `X-Target-Org-Id` string, nullable

## Response `200`

Successful Response

- ApiResponseVoicePayload
  - `data` VoicePayload, required: One voice object - a collection, an agent, a route, a chat. Open-shaped: voice adds fields to these bodies on its own release cadence and a dropped-or-added key must not be a 500 in this service.
  - `pagination` PaginationMeta
    - `page` integer, required: Current page number (1-indexed)
    - `limit` integer, required: Items per page
    - `total` integer, required: Total number of items
    - `has_next` boolean, required: Whether there are more pages
    - `next_cursor` string, nullable: Opaque cursor for the next page; null when there are no more items. Pass it back as the `cursor` query param to fetch the following page without computing page numbers.
    - `total_available` integer, nullable: Search endpoints only: how many records really match, when known. Can be larger than `total`, which is capped at the 10,000 results that can be paged. For company search this is a distinct-company estimate. Null when unknown; absent outside search.
    - `total_is_lower_bound` boolean, nullable: Search endpoints only: true when more records match than `total` shows (the result set is larger than the 10,000 results that can be paged). Absent outside search.
    - `notes` string[], nullable: Search endpoints only: plain-language notes about the result, e.g. that more records match than can be paged, or that a reversed `between` range was put in order.
