-   *
-   * [channelId] - The channelId parameter specifies a unique YouTube channel
-   * ID. The API will then return a list of that channel's activities.

-   * [home] - Set this parameter's value to true to retrieve the activity feed
-   * that displays on the YouTube home page for the currently authenticated
-   * user.
-   *
-   * [maxResults] - The maxResults parameter specifies the maximum number of
-   * items that should be returned in the result set.
-   * Value must be between "0" and "50".
-   *
-   * [mine] - Set this parameter's value to true to retrieve a feed of the
-   * authenticated user's activities.
-   *
-   * [pageToken] - 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.
-   *
-   * [publishedAfter] - The publishedAfter parameter specifies the earliest date
-   * and time that an activity could have occurred for that activity to be
-   * included in the API response. If the parameter value specifies a day, but
-   * not a time, then any activities that occurred that day will be included in

-   * format.
-   *
-   * [publishedBefore] - The publishedBefore parameter specifies the date and

-   * not a time, then any activities that occurred that day will be excluded
-   * from the result set. The value is specified in ISO 8601
-   * (YYYY-MM-DDThh:mm:ss.sZ) format.
-   *
-   * [regionCode] - The regionCode parameter instructs the API to return results
-   * for the specified country. The parameter value is an ISO 3166-1 alpha-2

-   * 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 the status.streamStatus property for the stream bound to
-   * your broadcast is active.
-   *
-   * Request parameters:
-   *
-   * [broadcastStatus] - The broadcastStatus parameter identifies the state to
-   * which the broadcast is changing. Note that to transition a broadcast to
-   * either the testing or live state, the status.streamStatus must be active
-   * for the stream that the broadcast is bound to.
-   * Possible string values are:
-   * - "complete" : The broadcast is over. YouTube stops transmitting video.
-   * - "live" : The broadcast is visible to its audience. YouTube transmits
-   * video to the broadcast's monitor stream and its broadcast stream.
-   * - "testing" : Start testing the broadcast. YouTube transmits video to the
-   * broadcast's monitor stream. Note that you can only transition a broadcast
-   * to the testing state if its
-   * contentDetails.monitorStream.enableMonitorStream property is set to true.
-   *
-   * [id] - The id parameter specifies the unique ID of the broadcast that is
-   * transitioning to another status.
-   *
-   * [part] - The part parameter specifies a comma-separated list of one or more
-   * liveBroadcast resource properties that the API response will include. The
-   * part names that you can include in the parameter value are id, snippet,
-   * contentDetails, and status.
-   *
-   * [onBehalfOfContentOwner] - 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] - This parameter can only be used in a
-   * properly authorized request. 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

-   *
-   * Request parameters:
-   *
-   * [part] - The part parameter serves two purposes in this operation. It
-   * identifies the properties that the write operation will set as well as the
-   * properties that the API response will include.
-   *
-   * The part properties that you can include in the parameter value are id,
-   * snippet, cdn, and status.
-   *
-   * Note that this method will override the existing values for all of the
-   * mutable properties that are contained in any parts that the parameter value
-   * specifies. If the request body does not specify a value for a mutable
-   * property, the existing value for that property will be removed.
-   *
-   * [onBehalfOfContentOwner] - 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] - This parameter can only be used in a
-   * properly authorized request. 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.
-   *

-   * Returns a collection of search results that match the query parameters
-   * specified in the API request. By default, a search result set identifies
-   * matching video, channel, and playlist resources, but you can also configure
-   * queries to only retrieve a specific type of resource.
-   *
-   * Request parameters:
-   *
-   * [part] - The part parameter specifies a comma-separated list of one or more
-   * search resource properties that the API response will include. Set the
-   * parameter value to snippet.
-   *
-   * [channelId] - The channelId parameter indicates that the API response
-   * should only contain resources created by the channel
-   *
-   * [channelType] - The channelType parameter lets you restrict a search to a
-   * particular type of channel.
-   * Possible string values are:
-   * - "any" : Return all channels.
-   * - "show" : Only retrieve shows.
-   *
-   * [eventType] - The eventType parameter restricts a search to broadcast
-   * events. If you specify a value for this parameter, you must also set the
-   * type parameter's value to video.
-   * Possible string values are:
-   * - "completed" : Only include completed broadcasts.
-   * - "live" : Only include active broadcasts.
-   * - "upcoming" : Only include upcoming broadcasts.
-   *
-   * [forContentOwner] - Note: This parameter is intended exclusively for
-   * YouTube content partners.
-   *
-   * The forContentOwner parameter restricts the search to only retrieve
-   * resources owned by the content owner specified by the
-   * onBehalfOfContentOwner parameter. The user must be authenticated using a
-   * CMS account linked to the specified content owner and
-   * onBehalfOfContentOwner must be provided.
-   *
-   * [forDeveloper] - The forDeveloper parameter restricts the search to only
-   * retrieve videos uploaded via the developer's application or website. The
-   * API server uses the request's authorization credentials to identify the
-   * developer. Therefore, a developer can restrict results to videos uploaded
-   * through the developer's own app or website but not to videos uploaded
-   * through other apps or sites.
-   *
-   * [forMine] - The forMine parameter restricts the search to only retrieve
-   * videos owned by the authenticated user. If you set this parameter to true,
-   * then the type parameter's value must also be set to video.
-   *
-   * [location] - The location parameter, in conjunction with the locationRadius
-   * parameter, defines a circular geographic area and also restricts a search
-   * to videos that specify, in their metadata, a geographic location that falls
-   * within that area. The parameter value is a string that specifies
-   * latitude/longitude coordinates e.g. (37.42307,-122.08427).
-   *
-   *
-   * - The location parameter value identifies the point at the center of the
-   * area.
-   * - The locationRadius parameter specifies the maximum distance that the
-   * location associated with a video can be from that point for the video to
-   * still be included in the search results.The API returns an error if your
-   * request specifies a value for the location parameter but does not also
-   * specify a value for the locationRadius parameter.
-   *
-   * [locationRadius] - The locationRadius parameter, in conjunction with the
-   * location parameter, defines a circular geographic area.
-   *
-   * The parameter value must be a floating point number followed by a
-   * measurement unit. Valid measurement units are m, km, ft, and mi. For
-   * example, valid parameter values include 1500m, 5km, 10000ft, and 0.75mi.
-   * The API does not support locationRadius parameter values larger than 1000
-   * kilometers.
-   *
-   * Note: See the definition of the location parameter for more information.
-   *
-   * [maxResults] - The maxResults parameter specifies the maximum number of
-   * items that should be returned in the result set.
-   * Value must be between "0" and "50".
-   *
-   * [onBehalfOfContentOwner] - 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.
-   *
-   * [order] - The order parameter specifies the method that will be used to
-   * order resources in the API response.
-   * Possible string values are:
-   * - "date" : Resources are sorted in reverse chronological order based on the
-   * date they were created.
-   * - "rating" : Resources are sorted from highest to lowest rating.
-   * - "relevance" : Resources are sorted based on their relevance to the search
-   * query. This is the default value for this parameter.
-   * - "title" : Resources are sorted alphabetically by title.
-   * - "videoCount" : Channels are sorted in descending order of their number of
-   * uploaded videos.
-   * - "viewCount" : Resources are sorted from highest to lowest number of
-   * views.
-   *
-   * [pageToken] - 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.
-   *
-   * [publishedAfter] - The publishedAfter parameter indicates that the API
-   * response should only contain resources created after the specified time.
-   * The value is an RFC 3339 formatted date-time value (1970-01-01T00:00:00Z).
-   *
-   * [publishedBefore] - The publishedBefore parameter indicates that the API
-   * response should only contain resources created before the specified time.

-   *
-   * [q] - The q parameter specifies the query term to search for.
-   *
-   * Your request can also use the Boolean NOT (-) and OR (|) operators to
-   * exclude videos or to find videos that are associated with one of several
-   * search terms. For example, to search for videos matching either "boating"
-   * or "sailing", set the q parameter value to boating|sailing. Similarly, to
-   * search for videos matching either "boating" or "sailing" but not "fishing",
-   * set the q parameter value to boating|sailing -fishing. Note that the pipe
-   * character must be URL-escaped when it is sent in your API request. The
-   * URL-escaped value for the pipe character is %7C.
-   *
-   * [regionCode] - The regionCode parameter instructs the API to return search
-   * results for the specified country. The parameter value is an ISO 3166-1
-   * alpha-2 country code.
-   *
-   * [relatedToVideoId] - The relatedToVideoId parameter retrieves a list of
-   * videos that are related to the video that the parameter value identifies.
-   * The parameter value must be set to a YouTube video ID and, if you are using
-   * this parameter, the type parameter must be set to video.
-   *
-   * [relevanceLanguage] - The relevanceLanguage parameter instructs the API to
-   * return search results that are most relevant to the specified language. The
-   * parameter value is typically an ISO 639-1 two-letter language code.
-   * However, you should use the values zh-Hans for simplified Chinese and
-   * zh-Hant for traditional Chinese. Please note that results in other
-   * languages will still be returned if they are highly relevant to the search
-   * query term.
-   *

-   * results should include restricted content as well as standard content.
-   * Possible string values are:
-   * - "moderate" : YouTube will filter some content from search results and, at
-   * the least, will filter content that is restricted in your locale. Based on
-   * their content, search results could be removed from search results or
-   * demoted in search results. This is the default parameter value.
-   * - "none" : YouTube will not filter the search result set.
-   * - "strict" : YouTube will try to exclude all restricted content from the
-   * search result set. Based on their content, search results could be removed
-   * from search results or demoted in search results.
-   *
-   * [topicId] - The topicId parameter indicates that the API response should
-   * only contain resources associated with the specified topic. The value
-   * identifies a Freebase topic ID.
-   *
-   * [type] - The type parameter restricts a search query to only retrieve a
-   * particular type of resource. The value is a comma-separated list of
-   * resource types.
-   *
-   * [videoCaption] - The videoCaption parameter indicates whether the API
-   * should filter video search results based on whether they have captions. If
-   * you specify a value for this parameter, you must also set the type
-   * parameter's value to video.
-   * Possible string values are:
-   * - "any" : Do not filter results based on caption availability.
-   * - "closedCaption" : Only include videos that have captions.
-   * - "none" : Only include videos that do not have captions.

-   * Returns subscription resources that match the API request criteria.
-   *
-   * Request parameters:
-   *
-   * [part] - The part parameter specifies a comma-separated list of one or more
-   * subscription resource properties that the API response will include.
-   *
-   * If the parameter identifies a property that contains child properties, the
-   * child properties will be included in the response. For example, in a
-   * subscription resource, the snippet property contains other properties, such
-   * as a display title for the subscription. If you set part=snippet, the API
-   * response will also contain all of those nested properties.
-   *
-   * [channelId] - The channelId parameter specifies a YouTube channel ID. The
-   * API will only return that channel's subscriptions.
-   *
-   * [forChannelId] - The forChannelId parameter specifies a comma-separated
-   * list of channel IDs. The API response will then only contain subscriptions
-   * matching those channels.
-   *
-   * [id] - The id parameter specifies a comma-separated list of the YouTube
-   * subscription ID(s) for the resource(s) that are being retrieved. In a
-   * subscription resource, the id property specifies the YouTube subscription
-   * ID.
-   *
-   * [maxResults] - The maxResults parameter specifies the maximum number of
-   * items that should be returned in the result set.
-   * Value must be between "0" and "50".
-   *
-   * [mine] - Set this parameter's value to true to retrieve a feed of the
-   * authenticated user's subscriptions.
-   *
-   * [myRecentSubscribers] - Set this parameter's value to true to retrieve a
-   * feed of the subscribers of the authenticated user in reverse chronological
-   * order (newest first).
-   *
-   * [mySubscribers] - Set this parameter's value to true to retrieve a feed of
-   * the subscribers of the authenticated user in no particular order.
-   *
-   * [onBehalfOfContentOwner] - 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] - This parameter can only be used in a
-   * properly authorized request. 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.
-   *
-   * [order] - The order parameter specifies the method that will be used to
-   * sort resources in the API response.
-   * Possible string values are:
-   * - "alphabetical" : Sort alphabetically.
-   * - "relevance" : Sort by relevance.
-   * - "unread" : Sort by order of activity.
-   *
-   * [pageToken] - 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.
-   *
-   * Completes with a [SubscriptionListResponse].
-   *
-   * Completes with a [commons.ApiRequestError] if the API endpoint returned an
-   * error.
-   *
-   * If the used [http.Client] completes with an error when making a REST call,
-   * this method will complete with the same error.

-   * Returns a list of videos that match the API request parameters.
-   *
-   * Request parameters:
-   *
-   * [part] - The part parameter specifies a comma-separated list of one or more
-   * video resource properties that the API response will include.
-   *
-   * If the parameter identifies a property that contains child properties, the
-   * child properties will be included in the response. For example, in a video
-   * resource, the snippet property contains the channelId, title, description,
-   * tags, and categoryId properties. As such, if you set part=snippet, the API
-   * response will contain all of those properties.
-   *
-   * [chart] - The chart parameter identifies the chart that you want to
-   * retrieve.
-   * Possible string values are:
-   * - "mostPopular" : Return the most popular videos for the specified content
-   * region and video category.
-   *
-   * [hl] - The hl parameter instructs the API to retrieve localized resource
-   * metadata for a specific application language that the YouTube website
-   * supports. The parameter value must be a language code included in the list
-   * returned by the i18nLanguages.list method.
-   *
-   * If localized resource details are available in that language, the
-   * resource's snippet.localized object will contain the localized values.
-   * However, if localized details are not available, the snippet.localized
-   * object will contain resource details in the resource's default language.
-   *
-   * [id] - The id parameter specifies a comma-separated list of the YouTube
-   * video ID(s) for the resource(s) that are being retrieved. In a video
-   * resource, the id property specifies the video's ID.
-   *
-   * [locale] - DEPRECATED
-   *
-   * [maxHeight] - The maxHeight parameter specifies a maximum height of the
-   * embedded player. If maxWidth is provided, maxHeight may not be reached in
-   * order to not violate the width request.
-   * Value must be between "72" and "8192".
-   *
-   * [maxResults] - The maxResults parameter specifies the maximum number of
-   * items that should be returned in the result set.
-   *
-   * Note: This parameter is supported for use in conjunction with the myRating
-   * and chart parameters, but it is not supported for use in conjunction with
-   * the id parameter.
-   * Value must be between "1" and "50".
-   *
-   * [maxWidth] - The maxWidth parameter specifies a maximum width of the
-   * embedded player. If maxHeight is provided, maxWidth may not be reached in
-   * order to not violate the height request.
-   * Value must be between "72" and "8192".
-   *
-   * [myRating] - Set this parameter's value to like or dislike to instruct the
-   * API to only return videos liked or disliked by the authenticated user.
-   * Possible string values are:
-   * - "dislike" : Returns only videos disliked by the authenticated user.
-   * - "like" : Returns only video liked by the authenticated user.
-   *
-   * [onBehalfOfContentOwner] - 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.
-   *
-   * [pageToken] - 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.
-   *
-   * Note: This parameter is supported for use in conjunction with the myRating
-   * and chart parameters, but it is not supported for use in conjunction with
-   * the id parameter.
-   *
-   * [regionCode] - The regionCode parameter instructs the API to select a video
-   * chart available in the specified region. This parameter can only be used in
-   * conjunction with the chart parameter. The parameter value is an ISO 3166-1
-   * alpha-2 country code.
-   *
-   * [videoCategoryId] - The videoCategoryId parameter identifies the video
-   * category for which the chart should be retrieved. This parameter can only
-   * be used in conjunction with the chart parameter. By default, charts are not
-   * restricted to a particular category.
-   *
-   * Completes with a [VideoListResponse].
-   *
-   * Completes with a [commons.ApiRequestError] if the API endpoint returned an
-   * error.
-   *
-   * If the used [http.Client] completes with an error when making a REST call,
-   * this method will complete with the same error.
