+    <code class="details" id="list">list(groupId=None, onBehalfOfContentOwner=None, x__xgafv=None)</code>
+  <pre>Returns a collection of group items that match the API request parameters.
+
+Args:
+  groupId: string, The `groupId` parameter specifies the unique ID of the group for which you
+want to retrieve group items.
+  onBehalfOfContentOwner: string, This parameter can only be used in a properly authorized request. **Note:**
+This parameter is intended exclusively for YouTube content partners that
+own and manage many different YouTube channels.
+
+The `onBehalfOfContentOwner` parameter indicates that the request&#x27;s
+authorization credentials identify a YouTube user who is acting on behalf
+of the content owner specified in the parameter value. 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 account that the user authenticates with must be
+linked to the specified YouTube content owner.
