# Video API, gRPC: StreamLineService.BatchGet

Retrieves multiple stream lines by their IDs in a specific channel in a single request.
This is more efficient than making multiple Get requests when retrieving several stream lines.

## gRPC request

**rpc BatchGet ([BatchGetStreamLinesRequest](#yandex.cloud.video.v1.BatchGetStreamLinesRequest)) returns ([BatchGetStreamLinesResponse](#yandex.cloud.video.v1.BatchGetStreamLinesResponse))**

## BatchGetStreamLinesRequest {#yandex.cloud.video.v1.BatchGetStreamLinesRequest}

```json
{
  "channel_id": "string",
  "stream_line_ids": [
    "string"
  ]
}
```

#|
||Field | Description ||
|| channel_id | **string**

Required field. ID of the channel containing the stream lines to retrieve.

The maximum string length in characters is 50. ||
|| stream_line_ids[] | **string**

List of stream line IDs to retrieve.

The maximum string length in characters for each value is 50. The number of elements must be in the range 1-100. ||
