The API now supports the ability to mark your live
broadcasts as "made for kids," and the
liveBroadcast
resource now contains a
property that identifies the "made for kids" status of that live broadcast. The YouTube API
Services Terms of Service and Developer Policies were also updated on 10 January 2020. For more
information, please see the revision histories for the
YouTube Live Streaming API Service and the
YouTube API Services Terms of Service.
A liveBroadcast
resource represents an event that will be streamed, via live video, on YouTube.
Methods
The API supports the following methods for liveBroadcasts
resources:
- list
- Returns a list of YouTube broadcasts that match the API request parameters. Try it now.
- insert
- Creates a broadcast. Try it now.
- update
- Updates a broadcast. For example, you could modify the broadcast settings defined in the
liveBroadcast
resource'scontentDetails
object. Try it now. - delete
- Deletes a broadcast. Try it now.
- bind
- Binds a YouTube broadcast to a stream or removes an existing binding between a broadcast and a stream. A broadcast can only be bound to one video stream, though a video stream may be bound to more than one broadcast. Try it now.
- transition
- Changes the status of a YouTube live broadcast and initiates any processes associated with the new status. For example, when you transition a broadcast's status to
testing
, YouTube starts to transmit video to that broadcast's monitor stream. Before calling this method, you should confirm that the value of thestatus.streamStatus
property for the stream bound to your broadcast isactive
. Try it now. - cuepoint
- Inserts a cuepoint into a live broadcast. The cuepoint might trigger an ad break.

Properties
The following table defines the properties that appear in this resource:
Properties | |
---|---|
kind |
string Identifies the API resource's type. The value will be youtube#liveBroadcast . |
etag |
etag The Etag of this resource. |
id |
string The ID that YouTube assigns to uniquely identify the broadcast. |
snippet |
object The snippet object contains basic details about the event, including its title, description, start time, and end time. |

datetime The date and time that the broadcast was added to YouTube's live broadcast schedule. The value is specified in ISO 8601 ( YYYY-MM-DDThh:mm:ss.sZ ) format. |
snippet.channelId |
string The ID that YouTube uses to uniquely identify the channel that is publishing the broadcast. |
snippet.title |
string The broadcast's title. Note that the broadcast represents exactly one YouTube video. You can set this field by modifying the broadcast resource or by setting the title field of the corresponding video resource. |
snippet.description |
string The broadcast's description. As with the title , you can set this field by modifying the broadcast resource or by setting the description field of the corresponding video resource. |
snippet.thumbnails |
object A map of thumbnail images associated with the broadcast. For each nested object in this object, the key is the name of the thumbnail image, and the value is an object that contains other information about the thumbnail. |
snippet.thumbnails.(key) |
object Valid key values are:
|
snippet.thumbnails.(key).url |
string The image's URL. |
snippet.thumbnails.(key).width |
unsigned integer The image's width. |

unsigned integer The image's height. |
snippet.scheduledStartTime |
datetime The date and time that the broadcast is scheduled to start. The value is specified in ISO 8601 ( YYYY-MM-DDThh:mm:ss.sZ ) format. Creator Studio supports the ability to create a broadcast without scheduling a start time. In this case, the broadcast starts whenever the channel owner starts streaming. For these broadcasts, the datetime value corresponds to UNIX time zero, and this value cannot be changed via the API or in Creator Studio. |
snippet.scheduledEndTime |
datetime The date and time that the broadcast is scheduled to end. The value is specified in ISO 8601 ( YYYY-MM-DDThh:mm:ss.sZ ) format. If a liveBroadcast resource does not specify a value for this property, then the broadcast is scheduled to continue indefinitely. Similarly, if you do not specify a value for this property, then YouTube treats the broadcast as if it will go on indefinitely. |
snippet.actualStartTime |
datetime The date and time that the broadcast actually started. This information is only available once the broadcast's state is live . The value is specified in ISO 8601 (YYYY-MM-DDThh:mm:ss.sZ ) format. |
snippet.actualEndTime |
datetime The date and time that the broadcast actually ended. This information is only available once the broadcast's state is complete . The value is specified in ISO 8601 (YYYY-MM-DDThh:mm:ss.sZ ) format. |
snippet.isDefaultBroadcast |
boolean
This property will be deprecated on or after September 1, 2020. At that time, YouTube will
stop creating a default stream and default broadcast when a channel is enabled for live
streaming. Please see the deprecation
announcement for more details.
This property indicates whether this broadcast is the default broadcast.How default broadcasts work When a YouTube channel is enabled for live streaming, YouTube creates a default stream and a default broadcast for the channel. The stream defines how the channel owner sends live video to YouTube, and the broadcast is how viewers can see the default stream. A channel owner can use the liveStreams.list and liveBroadcasts.list methods to identify these resources.When a channel starts streaming video to its default stream, the video is visible on the channel's default broadcast. When the stream ends, YouTube converts the completed broadcast to a YouTube video and assigns the video a YouTube video ID. After the conversion is complete, the video is included in the channel's list of uploaded videos. The video is not available immediately after the broadcast concludes, and the length of the delay is related to the actual length of the broadcast. |
snippet.liveChatId |
string The ID for the broadcast's YouTube live chat. With this ID, you can use the liveChatMessage resource's methods to retrieve, insert, or delete chat messages. You can also add or remove chat moderators, ban users from participating in live chats, or remove existing bans. |
status |
object The status object contains information about the event's status. |
status.lifeCycleStatus |
string The broadcast's status. The status can be updated using the API's liveBroadcasts.transition method.Valid values for this property are:

In addition, you can set this field by modifying the broadcast resource or by setting the privacyStatus field of the corresponding video resource.Valid values for this property are:
|
status.recordingStatus |
string The broadcast's recording status. Valid values for this property are:
|
status.madeForKids |
boolean This value indicates whether the broadcast is designated as child-directed. This property value is read-only. |
status.selfDeclaredMadeForKids |
boolean In a liveBroadcasts.insert
request, this property allows the channel owner to designate the broadcast as being
child-directed. In a
liveBroadcasts.list
request, the property value is only returned if the channel owner authorized the API
request. |
contentDetails |
object The contentDetails object contains information about the event's video content, such as whether the content can be shown in an embedded video player or if it will be archived and therefore available for viewing after the event has concluded. |
contentDetails.boundStreamId |
string This value uniquely identifies the live stream bound to the broadcast. |
contentDetails.boundStreamLastUpdateTimeMs |
datetime The date and time that the live stream referenced by boundStreamId was last updated. |
contentDetails.monitorStream |
object The monitorStream object contains information about the monitor stream, which the broadcaster can use to review the event content before the broadcast stream is shown publicly. |
contentDetails.monitorStream.enableMonitorStream |
boolean This value determines whether the monitor stream is enabled for the broadcast. If the monitor stream is enabled, then YouTube will broadcast the event content on a special stream intended only for the broadcaster's consumption. The broadcaster can use the stream to review the event content and also to identify the optimal times to insert cuepoints. You need to set this value to true if you intend to have a testing stage for your broadcast or if you want to have a broadcast delay for your event. In addition, if this property's value is true , then you must transition your broadcast to the testing state before you can transition it to the live state. (If the property's value is false , your broadcast cannot have a testing stage, so you can transition the broadcast directly to the live state.)When you update a broadcast , this property must be set if your API request includes the contentDetails part in the part parameter value. However, when you insert a broadcast , the property is optional and has a default value of true .Important: This property cannot be updated once the broadcast is in the testing or live state. |
contentDetails.monitorStream.broadcastStreamDelayMs |
unsigned integer If you have set the enableMonitorStream property to true , then this property determines the length of the live broadcast delay.When you update a broadcast , this property must be set if your API request includes the contentDetails part in the part parameter value. However, when you insert a broadcast , the property is optional and has a default value of 0 . This value indicates that the broadcast does not have a broadcast delay. Note: This property cannot be updated once the broadcast is in the testing or live state. |
contentDetails.monitorStream.embedHtml |
string HTML code that embeds a player that plays the monitor stream. |
contentDetails.enableEmbed |
boolean This setting indicates whether the broadcast video can be played in an embedded player. If you choose to archive the video (using the enableArchive property), this setting will also apply to the archived video.When you update a broadcast , this property must be set if your API request includes the contentDetails part in the part parameter value. However, when you insert a broadcast , the property is optional and has a default value of true .Note: This property cannot be updated once the broadcast is in the testing or live state. |
contentDetails.enableDvr |
boolean This setting determines whether viewers can access DVR controls while watching the video. DVR controls enable the viewer to control the video playback experience by pausing, rewinding, or fast forwarding content. The default value for this property is true . When you update a broadcast , this property must be set if your API request includes the contentDetails part in the part parameter value. However, when you insert a broadcast , the property is optional and has a default value of true .Important: You must set the value to true and also set the enableArchive property's value to true if you want to make playback available immediately after the broadcast ends. In addition, this property cannot be updated once the broadcast is in the testing or live state. |
contentDetails.recordFromStart |
boolean This setting indicates whether YouTube will automatically start recording the broadcast after the event's status changes to live. This property's default value is true , and it can only be set to false if the broadcasting channel is allowed to disable recordings for live broadcasts.If your channel does not have permission to disable recordings, and you attempt to insert a broadcast with the recordFromStart property set to false , the API will return a Forbidden error. In addition, if your channel does not have that permission and you attempt to update a broadcast to set the recordFromStart property to false , the API will return a modificationNotAllowed error.When you update a broadcast , this property must be set if your API request includes the contentDetails part in the part parameter value. However, when you insert a broadcast , the property is optional and has a default value of true .Important: You must also set the enableDvr property's value to true if you want the playback to be available immediately after the broadcast ends. If you set this property's value to true but do not also set the enableDvr property to true , there may be a delay of around one day before the archived video will be available for playback.Note: This property cannot be updated once the broadcast is in the testing or live state. |
contentDetails.enableClosedCaptions |
boolean This property has been deprecated as of December 17, 2015. Use the contentDetails.closedCaptionsType property instead.This setting indicates whether HTTP POST closed captioning is enabled for this broadcast. For API clients that are already using this property:
|
contentDetails.closedCaptionsType |
string Note: This property replaces the contentDetails.enableClosedCaptions property.This property indicates whether closed captioning is enabled for your broadcast and, if so, what type of closed captions you are providing:
|
contentDetails.projection |
string The projection format of this broadcast. The property's default value is rectangular .Valid values for this property are:
|
contentDetails.enableLowLatency |
boolean Indicates whether this broadcast should be encoded for low-latency streaming. A low-latency stream can reduce the amount of time it takes for video to be visible to users watching a broadcast, though it can also impact the resolution for viewers of the stream. |
contentDetails.latencyPreference |
string Indicates which latency setting to use for this broadcast. This property may be used instead of enableLowLatency , which does not support ultraLow .A low-latency stream can reduce the amount of time it takes for video to be visible to users watching a broadcast, though it can also affect the smoothness of playback. An ultra-low-latency stream further reduces the time it takes for video to be visible to viewers, making interaction with viewers easier, but ultra-low latency does not support closed captions, or resolutions higher than 1080p. Valid values for this property are:
|
contentDetails.enableAutoStart |
boolean Indicates whether this broadcast should start automatically when you start streaming video on the bound live stream . |
contentDetails.enableAutoStop |
boolean Indicates whether this broadcast should stop automatically around one minute after the channel owner stops streaming video on the bound video stream. |
statistics |
object The statistics object contains statistics related to a live broadcast. The values for these statistics can change during the broadcast and can only be retrieved while the broadcast is live. |
statistics.totalChatCount |
unsigned long The total number of live chat messages associated with the broadcast. The property and its value are present if the broadcast is visible to the user, has the live chat feature enabled, and has at least one message. Note that this property will not specify a value after the broadcast ends. So, this property would not identify the number of chat messages for an archived video of a completed live broadcast. |
monetizationDetails |
object The monetizationDetails object contains information about the stream's
monetization details, such as if the ads automator is turned on or if midroll ads insertion is
delayed. |
monetizationDetails.cuepointSchedule |
object The cuepointSchedule object specifies the ad automation settings for the
broadcast. |
monetizationDetails.cuepointSchedule.enabled |
boolean This value determines whether ads are automatically inserted in the broadcast. If the value is true , YouTube will automatically insert midroll ads into the broadcast. The
schedule for running ads will be determined by the value of the other fields in the
monetizationDetails.cuepointSchedule object.
|
monetizationDetails.cuepointSchedule.pauseAdsUntil |
datetime This value specifies that YouTube should not insert midroll ads into the broadcast until the specified date and time. The value is specified in ISO 8601 (YYYY-MM-DDThh:mm:ss.sZ) format. The value must be set to a future datetime to pause ads; the field value can also be set to a near future datetime to unpause ads when time passes. |
monetizationDetails.cuepointSchedule.scheduleStrategy |
string This value specifies the strategy that YouTube should follow for scheduling cuepoints. Valid values are:
|
monetizationDetails.cuepointSchedule.repeatIntervalSecs |
unsigned integer This value specifies the interval, in seconds, between automatic ad insertion during a broadcast. For example, if the value is 300 , YouTube can insert midroll ad cuepoints at
five minute intervals.Note that the value specifies the time between the start of successive cuepoints. That is, the interval is not measured from the end of one cuepoint to the start of the next. |
