# Actionable Notifications

> Add custom action buttons to standard iOS push notifications using the MoEngage SDK.

Actionable notifications let you add custom action buttons to the standard iOS push notifications. It also gives the user a quick and easy way to perform relevant tasks in response to a notification.

# How to implement Actionable Notifications?

## Define a category

To use actionable notifications with MoEngage SDK, you have to define the actions, group them into categories, as shown in the example, and pass them as a parameter while registering for push notifications.

<CodeGroup>
  ```swift Swift wrap theme={null}
  @UIApplicationMain
  class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate{

      var window: UIWindow?
      

      func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

          //--- Rest of Implementation
        
          //For registering for remote notification
          let categories = self.getCategories()
          MoEngageSDKMessaging.sharedInstance.registerForRemoteNotification(withCategories: categories, andUserNotificationCenterDelegate:self)
          
          //--- Rest of Implementation
          
          return true
      }
      
      //Example to define categories
      //This method gives categories
      func getCategories() -> Set<UNNotificationCategory>{
          
          let acceptAction = UNNotificationAction.init(identifier: "ACCEPT_IDENTIFIER", title: "Accept", options: .authenticationRequired)
          let declineAction = UNNotificationAction.init(identifier: "DECLINE_IDENTIFIER", title: "Decline", options: .destructive)
          let maybeAction = UNNotificationAction.init(identifier: "MAYBE_IDENTIFIER", title: "May Be", options: .foreground)
          
          let inviteCategory = UNNotificationCategory.init(identifier: "INVITE_CATEGORY", actions: [acceptAction,declineAction,maybeAction], intentIdentifiers: [], options: .customDismissAction)
          let categoriesSet = Set.init([inviteCategory])
          
          return categoriesSet;
      }
  }
  ```

  ```objective-c Objective C wrap theme={null}
  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOption
  {
   ---------
      
      NSSet* categories = [self getNotificationCategories];
    	[[MoEngageSDKMessaging sharedInstance] registerForRemoteNotificationWithCategories:categories andUserNotificationCenterDelegate:self];
      }
    
   ---------
      return YES;
  }

  //Example to define categories
  //This method gives categories 
  -(NSSet*)getNotificationCategories{

      UNNotificationAction *acceptAction = [UNNotificationAction actionWithIdentifier:@"ACCEPT_IDENTIFIER" title:@"Accept" options:UNNotificationActionOptionAuthenticationRequired];
      UNNotificationAction *declineAction = [UNNotificationAction actionWithIdentifier:@"DECLINE_IDENTIFIER" title:@"Decline" options:(UNNotificationActionOptionDestructive)];
      UNNotificationAction *maybeAction = [UNNotificationAction actionWithIdentifier:@"MAYBE_IDENTIFIER" title:@"May Be" options:UNNotificationActionOptionNone];
      
      UNNotificationCategory* inviteCategory = [UNNotificationCategory categoryWithIdentifier:@"INVITE_CATEGORY"actions:@[acceptAction,maybeAction, declineAction,opt4Action] intentIdentifiers:@[] options:UNNotificationCategoryOptionNone];
      
      NSSet *categories = [NSSet setWithObjects:inviteCategory,nil];
      
      return categories;
  }
  ```

<Info>
  **Notification Categories**

  MoEngage recommended not to change the actions grouped in a category across the app versions, as it will lead to users seeing different actions for the same category across different app versions.
