# LiveStreams: list

Returns a list of video streams that match the API request parameters.

## Common use cases

The list below shows common use cases for this method. Hover over a use case to see its description, or click on a use case to load sample parameter values in the APIs Explorer. You can open the [fullscreen APIs Explorer](https://developers.google.com/youtube/v3/live/docs/liveStreams/list#) to see code samples that dynamically update to reflect the parameter values entered in the Explorer.

The table below shows common use cases for this method. You can click on a use case name to load sample parameter values in the APIs Explorer. Or you can see code samples for a use case in the fullscreen APIs Explorer by clicking on the code icon below a use case name. In the fullscreen UI, you can update parameter and property values and the code samples will dynamically update to reflect the values you enter.  
This method has one common use case, which is described below. The buttons below the description populate the APIs Explorer with sample values or open the fullscreen APIs Explorer to show code samples that use those values. The code samples also dynamically update if you change the values.

| `part`                          | `string` The **part** parameter specifies a comma-separated list of one or more `liveStream` resource properties that the API response will include.

| `mine`                          | `boolean` This parameter can only be used in a properly [authorized request](https://developers.google.com/youtube/v3/live/authentication). The **mine** parameter can be used to instruct the API to only return streams owned by the authenticated user. Set the parameter value to `true` to only retrieve your own streams.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |

| `maxResults`                    | `unsigned integer` The **maxResults** parameter specifies the maximum number of items that should be returned in the result set. Acceptable values are `0` to `50`, inclusive. The default value is `5`.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   |
| `onBehalfOfContentOwner`        | `string` This parameter can only be used in a properly [authorized request](https://developers.google.com/youtube/v3/live/authentication). **Note:** This parameter is intended exclusively for YouTube content partners. The **onBehalfOfContentOwner** parameter indicates that the request's authorization credentials identify a YouTube CMS user who is acting on behalf of the content owner specified in the parameter value. This parameter is intended for YouTube content partners that own and manage many different YouTube channels. It allows content owners to authenticate once and get access to all their video and channel data, without having to provide authentication credentials for each individual channel. The CMS account that the user authenticates with must be linked to the specified YouTube content owner.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              |
| `onBehalfOfContentOwnerChannel` | `string` This parameter can only be used in a properly [authorized request](https://developers.google.com/youtube/v3/live/authentication). This parameter can only be used in a properly [authorized request](https://developers.google.com/youtube/v3/guides/authentication). **Note:** This parameter is intended exclusively for YouTube content partners. The **onBehalfOfContentOwnerChannel** parameter specifies the YouTube channel ID of the channel to which a video is being added. This parameter is required when a request specifies a value for the `onBehalfOfContentOwner` parameter, and it can only be used in conjunction with that parameter. In addition, the request must be authorized using a CMS account that is linked to the content owner that the `onBehalfOfContentOwner` parameter specifies. Finally, the channel that the `onBehalfOfContentOwnerChannel` parameter value specifies must be linked to the content owner that the `onBehalfOfContentOwner` parameter specifies. This parameter is intended for YouTube content partners that own and manage many different YouTube channels. It allows content owners to authenticate once and perform actions on behalf of the channel specified in the parameter value, without having to provide authentication credentials for each separate channel. |
| `pageToken`                     | `string` The **pageToken** parameter identifies a specific page in the result set that should be returned. In an API response, the `nextPageToken` and `prevPageToken` properties identify other pages that could be retrieved.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            |
