# Get a channel's simulcast targets

GET https://api.fastpix.com/v1/cloud-playout/channels/simulcast/{channelId}

This endpoint retrieves the third-party platforms a Cloud Playout channel is being restreamed to, along with the channel's own playback ID.

#### How it works

1. Make a GET request to this endpoint with the `channelId`.

2. The response returns the channel's playback ID, the ID of the stream behind it, and every simulcast target on it.

3. Use a target's `simulcastId`, together with the `destinationLiveId`, to remove it.

#### Example

An operator checks which platforms a channel is currently going out to before adding another one.

## Authentication

- `Authorization` header (basic auth, required) — FastPix APIs are secured with Basic Authentication. Use your Access Token ID as the username and Secret Key as the password in the Authorization header of each API request. * Username: Access Token ID * Password: Secret Key Activate your FastPix account to generate your API credentials. See the guide here

## Request

### Path parameters

- `channelId` (string, required) — The unique identifier of the channel whose simulcast targets are retrieved.

## Response

### 200

Simulcast targets retrieved successfully

- `success` (boolean, optional) — Shows the request status. Returns true for success and false for failure.
- `data` (CloudPlayoutSimulcastListResponseData, optional)

## Types

### CloudPlayoutSimulcastListResponseData

- `destinationLiveId` (string, optional) — The unique identifier of the stream behind the channel. Use it as the `livestreamId` when you remove a simulcast target.
- `playbackId` (string, optional, nullable) — The unique identifier used to build the channel's own playback URL.
- `simulcastResponses` (list of liveSimulcast, optional) — The third-party platforms the channel is being restreamed to.

### liveSimulcast

- `simulcastId` (string, optional) — When you create the new simulcast, FastPix assign a universal unique identifier which can contain a maximum of 255 characters.
- `url` (string, optional) — The RTMPS hostname, combined with the application name, is crucial for connecting to third-party live streaming services and transmitting the live stream.
- `streamKey` (string, optional) — A unique stream key is generated for streaming, allowing the user to start streaming on any third-party platform using this key.
- `isEnabled` (boolean, optional) — When the value is true, the simulcast must be enabled for the given stream
- `metadata` (map from string to string, optional) — You can search for videos with specific key value pairs using metadata, when you tag a video in "key":"value"s pairs. Dynamic metadata allows you to define a key that allows any value pair. You can have maximum of 255 characters and upto 10 entries are allowed.
