Notifications iOS

Configure Push and In-app notifications.

Note

All the public APIs in the SDK should be called after initializing the SDK via HelpshiftSdk.install() API

Note

An easy way to setup push notifications is to uncomment relevant code in the HsUnityAppController.mm file. The class HsUnityAppController implements the AppDelegateListener and provides relevant delegate methods needed to get started with push notifications.

Notifications can be sent to your users when:

• You reply to an issue submitted by them
• You send a Proactive Engagement notification targeting the user

Setting push notifications involves configuring both the Helpshift admin dashboard as well as the client app.

Configure push notifications in the Helpshift admin dashboard

Configure Helpshift's push notification service in the Helpshift admin interface

To enable the Helpshift system to send push notifications to your users you will have to add iOS as a platform in your app (if you have not added already). And then click on the push notifications option.

In order to send push notifications to all iOS mobile apps and games, you need to establish an authenticated connection with the Apple Push Notification Servers (APNs). There are two methods you can use to authenticate:

1. The newer token-based method (.p8)
2. The older certificate-based method (.p12)

Token-based method (.p8)

The token-based method is faster because it offers a stateless way to communicate with APNs. It doesn't require APNs to look up the certificate or any other information related to the provider server.

We now support the newer token-based .p8 key method, which allows you to send notifications to all your iOS apps and games using a single key. You can generate your .p8 key through your Apple developer account, as explained here.

Here are the steps to configure iOS push notifications using .p8 keys:

1. Go to Settings, then navigate to the APP SETTINGS section to choose the app you want to configure.

2. On the App settings page, click on the CONFIGURE option next to In-app SDK.

3. On the In-app SDK Configuration page, navigate to the Push Notification section.

4. Enable the toggle for Apple Push Notification Service if not enabled. The app selects the p8 key authentication type by default when you enable the toggle for the first time.

5. Upload the p8 key and fill in all the required details.

6. Select the APNs push mode (Development/Production).

7. Click on Save & Publish to save the changes.

Note

You can also switch from .p8 key to .p12 certificate method if required, by selecting .p12 in Authentication type and filling the details.

Certificate-based method (.p12)

You need to generate certificates for APNS on Apple's portal that you can later provide to Helpshift. This lets Helpshift send push notifications to your users. Apple has moved away from old type of certificates to Apple Push Notification service SSL. There is another option to create Apple Push Notification Authentication Key, but Helpshift does not support this option yet. It's also possible that you still have the old type of certificate that has not yet expired, this is also supported by Helpshift.

Apple provides two variations of Apple Push Notification service SSL

• Apple Push Notification service SSL (Sandbox)
• Apple Push Notification service SSL (Sandbox & Production)

After creating your certificate, download it. Double click on it to import it to the Keychain Access application. In the Keychain Access application, right click on the certificate that was just added, and click export it in .p12 format. Please provide a password while exporting the certificate since we do not accept empty passwords. (Note that if your development private key is not present in Keychain Access, you will not be able to export it in .p12 format.)

After export, login and upload the .p12 file in your app in the Helpshift admin panel. Provide the same password you used while exporting to .p12 format.

Please note that you need to use the same bundle identifier in the app as the one you used to create the APNS certificate.

You can configure whether to send a badge or not, and sound alerts if you provided custom sounds bundled with your app to handle notifications. Save it and you're all set.

Development (Sandbox) mode vs. Production mode

When you build and run your app from Xcode, it is in development (Sandbox) mode. To test push notifications from Helpshift in this mode make sure you choose 'Development Mode' while uploading either of the above two certificate types.

When you publish your app and download from App Store, your app is in Production mode. To test push notifications from Helpshift in production mode make sure you choose 'Production Mode' while uploading a certificate of 'Apple Push Notification service SSL (Sandbox & Production)' type. Sandbox mode certificate will not work on a production environment.

We do not support using the same certificate for both sandbox and production apps. In these cases we recommend you create two separate apps on our dashboard, one in 'Production mode' and the other in 'Development mode'. While testing please use the credentials of the developement mode app. When you are ready to publish, please replace the credentials with those of the production level app.

Note

Your Push Certificate has an expiry date, as indicated in the below screenshot. Helpshift will not send you a reminder when your Push Certificate expires, so please make sure that your developer keeps a tab on the expiry date to reupload the Push Certificate.

Configure the Helpshift iOS SDK to handle notifications

Note

When push is not configured, Helpshift SDK shows out-of-the-box "in-app notifications" for every message sent by Agents/Bots. You should call registerDeviceToken API only after you have configured the Helpshift dashboard for push notifications. Calling the registerDeviceToken API without configuring the Helpshift dashboard will stop showing out-of-the-box "in-app notifications" for the end users.

Request notification permission and register your app for push

If your app does not already use push, you will need to enable push for your app. To enable push notification in your application you need to add APNS registration code to your AppDelegate's application:didFinishLaunchingWithOptions: method:

- (BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
                          completionHandler:^(BOOL granted, NSError *_Nullable error) {
        if(!granted) {
            NSLog(@"Notification auth denied");
        } else {
            NSLog(@"Notification auth granted");
            dispatch_async(dispatch_get_main_queue(), ^{
                [UIApplication.sharedApplication registerForRemoteNotifications];
            });
        }
    }];
}

Pass registered push token to Helpshift

For Helpshift SDK to work with the Helpshift push notification service you will need to invoke the registerDeviceToken: api call inside the application delegate method application:didRegisterForRemoteNotificationsWithDeviceToken:

In your app delegate file it will look something like this:

- (void) application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [Helpshift registerDeviceToken:deviceToken];
}

Implement push delegates

To respond to the delivery of notifications, you must implement a delegate for the shared UNUserNotificationCenter object. Your delegate object must conform to the UNUserNotificationCenterDelegate protocol, which the notification center uses to deliver notification information to your app:

• If a notification arrives while your app is in the foreground, UNUserNotificationCenterDelegate's userNotificationCenter:willPresentNotification:withCompletionHandler: is called.
• If a notification arrives while your app is in background or terminated, the system does not call the userNotificationCenter:willPresentNotification:withCompletionHandler: method. Instead, the system alerts the user according to the information in the notification itself.
• When the user selects an action from the notification interface, the system notifies your app of the user's choice. To receive responses, your delegate object must implement the userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler: method.

In both cases, you should check the "origin" field of the notification dictionary and call the corresponding SDK APIs (mentioned below) if the origin is "helpshift". The Helpshift SDK will handle the notification transparently depending on it's payload:

Example usage:

• For notifications sent in response to agent replies on user's support conversations, the SDK will open the corresponding conversation.
• For proactive engagement notifications, the SDK will perform the dashboard configured action.

Push delegate when app is in foreground

For the userNotificationCenter:willPresentNotification:withCompletionHandler: delegate, invoke the handleForegroundNotification:withCompletionHandler: SDK API -

- (void) userNotificationCenter:(UNUserNotificationCenter *)center
        willPresentNotification:(UNNotification *)notification
          withCompletionHandler:(void (^)(UNNotificationPresentationOptions)) completionHandler {
    NSDictionary *userInfo = notification.request.content.userInfo;
    if([@"helpshift" isEqualToString:userInfo[@"origin"]]) {
        [Helpshift handleForegroundNotification:userInfo withCompletionHandler:completionHandler];
    } else {
        completionHandler(UNNotificationPresentationOptionBanner |
                          UNNotificationPresentationOptionSound  |
                          UNNotificationPresentationOptionList);
    }
}

Push delegate when app is in background or not running

For the userNotificationCenter:didReceiveNotificationResponse:withCompletionHandler delegate, invoke the handleBackgroundNotificationClick:withCompletionHandler: SDK API -

- (void) userNotificationCenter:(UNUserNotificationCenter *)center
 didReceiveNotificationResponse:(UNNotificationResponse *)response
          withCompletionHandler:(void (^)(void))completionHandler {
    NSDictionary *userInfo = response.notification.request.content.userInfo;
    if([@"helpshift" isEqualToString:userInfo[@"origin"]]) {
        [Helpshift handleBackgroundNotificationClick:userInfo withCompletionHandler:completionHandler];
    } else {
        completionHandler();
    }
    completionHandler();
}

Note

To test Push Notifications for an app that is already in production please refer this.

Configure NotificationService extension

Note

Your app only needs to configure the NotificationService extension if you are using Proactive Engagement feature. For support notifications, you can skip this configuration.

If you are using Helpshift's Proactive Engagement feature, you will need to add a NotificationService extension to your app. This extension lets the app intercept the notification and modify it's payload before iOS system posts the notification in system tray. For more details on what this service extension does and how to configure it in your app, you can refer the Apple documentation.

Helpshift uses this extension to download images to display in the push notification. If your app already has a NotificationService extension, you can re-use it for handling Helpshift notifications. In the didReceiveNotificationRequest:withContentHandler: method of your notification service, call the corresponding Helpshift API -

- (void) didReceiveNotificationRequest:(UNNotificationRequest *)request
                    withContentHandler:(void (^)(UNNotificationContent *content))contentHandler {
    NSString *origin = request.content.userInfo[@"origin"];
    if([@"helpshift" isEqualToString:origin]) {
        [Helpshift handleBackgroundNotification:request
                             withContentHandler:contentHandler];
    } else {
        contentHandler(request.content);
    }
}

In-app notifications

In-app notifications are similar to Apple's push notification banners. Unlike push notifications, they appear within your app when it is in use by the user.

These notifications are sent when an agent replies to a customer's issue. Your customers can click on these banners to go straight into the conversation screen.

Configuring In-app notifications

The Helpshift install call supports flags for configuring SDK behaviour. Currently we support one flag i.e enableInAppNotification.

Enabling/Disabling In-app notifications

Flag	enableInAppNotification
Values	true/false
Default	true

If you do not want the in-app notifications support provided by the Helpshift SDK, please set this flag to false. The default value of this flag is true i.e in-app notifications will be enabled.
Read more about in-app notifications in the Notifications section.

Example:

using Helpshift;

private HelpshiftSdk help;
this.help = HelpshiftSdk.GetInstance();
Dictionary<string, object> configMap = new Dictionary<string, object>();
configMap.Add(HelpshiftSdk.ENABLE_INAPP_NOTIFICATION, true);
help.Install(appId, domainName, configMap);

Pausing In-app notifications

Use the API pauseDisplayOfInAppNotification to pause/resume the notifications. When YES is passed to this method, display of in-app notifications is paused even if they arrive. When you pass NO, the in-app notifications start displaying. Note that if you have disabled support in-app notifications, this flag will have no effect for support notifications. It will still work for proactive engagement in-app notifications.

Example:

using Helpshift;

// Install call
private HelpshiftSdk help;
this.help = HelpshiftSdk.GetInstance();
Dictionary<string, object> configMap = new Dictionary<string, object>();
configMap.Add(HelpshiftSdk.ENABLE_INAPP_NOTIFICATION, true);
help.Install(appId, domainName, configMap);

// To temporarily pause in-app notifications
help.PauseDisplayOfInAppNotification(true);

// To resume showing the in-app notifications
help.PauseDisplayOfInAppNotification(false);

Notification badges

If you want to show your user notifications for replies you send to the issues they posted, you can use notification counts provided by Helpshift SDK that gives you the total number of unread messages and display it as a badge. You can get notification counts asynchronously by implementing the IHelpshiftEventsListener in your respective .cs file. Notifications are typically displayed as badges inside your app where a user invokes the help section. These badges can be displayed anywhere in your app's interface to tell the user that they have unread replies/messages from you. For example to display a badge on a view (lets say its called yourView which can set its textLabel) while you are polling for notifications using:

Helpshift.RequestUnreadMessageCount(true)

Please note that before calling this method, you need to set the listener for Helpshift events by calling the Helpshift.SetHelpshiftEventsListener(eventsListener) API.

You can implement something like the following in the notification count delegate method:

public class HSEventsListener : IHelpshiftEventsListener
{
    // ...
    public void HandleHelpshiftEvent(string eventName, Dictionary<string, object> eventData)
    {
      if(eventName.Equals(HelpshiftEvent.RECEIVED_UNREAD_MESSAGE_COUNT))
      {
        Debug.Log("Unread count: " + eventData[HelpshiftEvent.DATA_MESSAGE_COUNT]);
        Debug.Log("Is Unread count from cache: " + eventData[HelpshiftEvent.DATA_MESSAGE_COUNT_FROM_CACHE]);

        // Do something with the unread count here, for example, update the badge count.
      }
    }
    //...
}

The notification count is fetched via this API from the SDK cache and Helpshift's servers (indicated by the value of fromCache in the example above). However, the count from Helpshift’s servers is rate limited and it returns the value only if a subsequent call is made to the API, after the reset timeout or when the user just closes the chat screen (whichever is earlier). For an active issue, the reset timeout is 1 minute and 5 minutes for inactive issues.

Reset badge count

If you need to handle badge reset in the application icon, you can do something like below in the applicationDidBecomeActive: delegate method:

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
