+# App notification collections
+
+Use collections to organize your app's notifications in Notification Center. Collections help users locate information more easily and allow developers to better manage their notifications.
+
+A messaging app, for example, can separate notifications by chat group. Each group title ("Comp Sci 160A Project Chat", "Direct Messages", "Lacrosse Team Chat") is a separate collection. Notifications are grouped as if they were from a separate app, even though they all come from the same app. For a more subtle way to organize notifications, see [App notification headers](app-notifications-headers.md).
+
+![Collection Example with two different Groups of Notifications](images/toast-collection-example.png)
+
+> [!NOTE]
+> The code examples in this article use the `Microsoft.Windows.AppNotifications` namespace to build notification content and the `Windows.UI.Notifications` namespace for collection management. These two namespaces can be used together in the same app.
+
+For more information about app notifications, see [App notifications overview](index.md).
+
+## Create a collection
+
+When creating a collection, provide a display name and an icon, which are shown in Notification Center as part of the collection's title. Collections also require a launch argument so your app can navigate to the right location when the user clicks the collection title. Create the collection by calling [**SaveToastCollectionAsync**](/uwp/api/windows.ui.notifications.toastcollectionmanager.savetoastcollectionasync).
+
+```csharp
+using Windows.UI.Notifications;
+
+var collection = new ToastCollection(
+    "MyToastCollection",
+    "Work Email",
+    "NavigateToWorkEmailInbox",
+    new Uri("ms-appx:///Assets/workEmail.png"));
+
+await ToastNotificationManager.GetDefault()
+    .GetToastCollectionManager()
+    .SaveToastCollectionAsync(collection);
+```
+
+## Send a notification to a collection
+
+Use [**AppNotificationBuilder**](/windows/windows-app-sdk/api/winrt/microsoft.windows.appnotifications.builder.appnotificationbuilder) to construct the notification content, then call [**GetToastNotifierForToastCollectionIdAsync**](/uwp/api/windows.ui.notifications.toastnotificationmanagerforuser.gettoastnotifierfortoastcollectionidasync) to get a notifier scoped to the collection.
+
+```csharp
+using Microsoft.Windows.AppNotifications.Builder;
+using Windows.UI.Notifications;
+using Windows.Data.Xml.Dom;
+
+// Build notification content with Windows App SDK
+var payload = new AppNotificationBuilder()
+    .AddText("Adam sent a message to the group")
+    .BuildNotification()
+    .Payload;
+
+// Deliver to a collection using the WinRT API
+var doc = new XmlDocument();
+doc.LoadXml(payload);
+var toast = new ToastNotification(doc);
+
+var notifier = await ToastNotificationManager.GetDefault()
+    .GetToastNotifierForToastCollectionIdAsync("MyToastCollection");
+notifier.Show(toast);
+```
+
+## List all collections
+
+Retrieve all collections created for your app by calling [**FindAllToastCollectionsAsync**](/uwp/api/windows.ui.notifications.toastcollectionmanager.findalltoastcollectionsasync).
+
+```csharp
+var collectionManager = ToastNotificationManager.GetDefault().GetToastCollectionManager();
+var collections = await collectionManager.FindAllToastCollectionsAsync();
+```
+
+## Update a collection
+
+Update a collection by creating a new [**ToastCollection**](/uwp/api/windows.ui.notifications.toastcollection) instance with the same ID and calling [**SaveToastCollectionAsync**](/uwp/api/windows.ui.notifications.toastcollectionmanager.savetoastcollectionasync).
+
+```csharp
+var collectionManager = ToastNotificationManager.GetDefault().GetToastCollectionManager();
+
+var updatedCollection = new ToastCollection(
+    "MyToastCollection",
+    "Updated Display Name",
+    "UpdatedLaunchArgs",
+    new Uri("ms-appx:///Assets/updatedPicture.png"));
+
+await collectionManager.SaveToastCollectionAsync(updatedCollection);
+```
+
+## Remove a collection
+
+Remove a collection by calling [**RemoveToastCollectionAsync**](/uwp/api/windows.ui.notifications.toastcollectionmanager.removetoastcollectionasync) with the collection ID. Any notifications in the collection are also removed from Notification Center.
+
+```csharp
+var collectionManager = ToastNotificationManager.GetDefault().GetToastCollectionManager();
+await collectionManager.RemoveToastCollectionAsync("MyToastCollection");
+```
+
+## Remove notifications within a collection
+
+Use the **Tag** and **Group** properties to identify and remove individual notifications within a collection by calling [**Remove**](/uwp/api/windows.ui.notifications.toastnotificationhistory.remove), or clear all notifications at once with [**Clear**](/uwp/api/windows.ui.notifications.toastnotificationhistory.clear).
+
+```csharp
+var collectionHistory = await ToastNotificationManager.GetDefault()
+    .GetHistoryForToastCollectionAsync("MyToastCollection");
+
+// Remove a specific notification
+collectionHistory.Remove(tag, group);
+
+// Or clear all notifications in the collection
+collectionHistory.Clear();
+```
