This article explains how to enable push notifications in Intercom for iOS. If you are new to push notifications in iOS, check out this page first.

To enable push notifications in Intercom you first need to create a production PEM file of your Apple Push Certificate and upload it to Intercom.

Important: Please be aware that currently Intercom only supports push notifications with Apple's production APNS service. We do not currently support push notifications in a development capacity. That means that the PEM files needed to send push notifications to your app must be for Apple's production environment, and subsequently in order to test Intercom push notifications you need to test with a production (adhoc) build of your app.

Step 1. Create App ID and APNS SSL Certificate

You can skip this step if you have already configured your iOS app to support the Apple Push Notification Service (APNS).

Login to your Apple developer account. Create an App ID identifier for your app. Make sure you enable the 'Push Notifications' option. Submit and Edit the App ID again to create the Production SSL Certificate:

Follow the steps as described (Select type, create a Certificate Signing Request, Generate and Download the certificate). Double click the certificate (.cer file) to import it into your keychain.

Step 2. Export your APNS SSL Certificate

First, launch "Keychain Access" on your Mac and find the iOS push certificate for your app. This will be within the “My Certificates" category. You will know it is the correct one as it will start with “Apple Production iOS Push Services:" followed by the bundle id of your app.

Next, select both the certificate and the private key it contains, then right click and choose to export. Make sure that the file format is set to “ Personal Information Exchange (.p12)" and save it to your Desktop.

Important: Do not enter a password when prompted for protecting the export.

Next you will need to create a PEM file from this newly exported .p12. You can do this easily in the terminal by moving into your Desktop directory or wherever you saved the .p12 file. Then enter this command:

openssl pkcs12 -in Certificates.p12 -out Certificates.pem -nodes

You should now have the PEM file created on your Desktop.

Step 3. Upload PEM file to Intercom

Go to your app's settings page in Intercom and find the iOS Integrations page. You'll notice the "Enable Push Notifications" section where you'll be able to upload your newly created PEM file. NOTE: Intercom currently only supports production APNS environments. In order to test push in your app you will need to create and deploy an AdHoc build and distribute it via iTunes, Hockey, TestFlight or using another distribution tool.

Step 4. Download the Provisioning Profile

You can skip this step if you have already configured your iOS app to support the Apple Push Notification Service (APNS).

  1. Login to your Apple developer account. Create an iOS Provisioning Profile for the Production environment.
  2. Select the App ID you created in Step 1 and generate / download the profile.
  3. Double click the .mobileprovision file to import it into Xcode.
  4. In the Xcode Build Settings for your target, select the correct Code Signing Identify and Provisioning Profile for the Release level.
  5. Install a Release build of the app on your iOS device (e.g. by selecting Release in your Xcode scheme and running the app).

Step 5. Register with APNS and register Device Tokens

As usual, you should also register with the Apple Push Notification Service (APNS) by adding this code to applicationDidBecomeActive if you haven't already:

- (void)applicationDidBecomeActive:(UIApplication *)application {    
    if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]){ // iOS 8 (User notifications)
        [application registerUserNotificationSettings:
         [UIUserNotificationSettings settingsForTypes:
          (UIUserNotificationTypeBadge |
           UIUserNotificationTypeSound |
        [application registerForRemoteNotifications];
    } else { // iOS 7 (Remote notifications)
        [application registerForRemoteNotificationTypes:
         (UIRemoteNotificationTypeBadge |
          UIRemoteNotificationTypeSound |

In order to enable your users receive push notifications from Intercom via Intercom for iOS, you must register the device token of your user in the standard didRegisterForRemoteNotificationsWithDeviceToken: method:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    [Intercom setDeviceToken:deviceToken];

Step 6. Handling Intercom Push Notifications

When your app receives a push notification Intercom for iOS checks to see if it is an Intercom push notification and opens the message if required. You do not need to implement any additional code in order to launch Intercom's UI once you have followed the instructions in step 5 above. To do this we safely swizzle the public methods in `UIApplicationDelegate` that handle receiving push notifications. We do not use any private APIs to do this.

Step 7. Testing Intercom Push Notifications

You can easily test if push notifications are working properly in your app. Just send a manual message to the app user via Intercom.

Badge Values

Intercom never changes the badge value of your app. Thus we can ensure that whatever badge value you're managing in your app, we don't alter in any way.


If you are having trouble getting push notifications to work in your app, here's a list of things you should check:

  • Ensure you ticked the box 'Send a push notification' when you send a manual message.
  • When your push-enabled app registers for push notifications for the first time on a device, iOS asks the user if they wish to receive notifications for that app. So please verify that when you launch your app for the first time iOS shows you this alert view. You should tap OK in this case to allow iOS to send you push notifications.
  • Do you get a token from APNS? If you put a breakpoint into the application:didRegisterForRemoteNotificationsWithDeviceToken: delegate call, you should get a token shortly after your app launches.
  • Did you generate and upload the PEM file correctly? Make sure you downloaded the productionAPNS SLL certificate. Also, ensure you exported both the certificate and private key, and you created the p12 file with an empty password. Double-check that you uploaded the PEM file to the correct Intercom app (TEST vs. Production).
  • Did you install a Production build on your device (with the correct provisioning profile)? For now, Intercom push won't work with the APNS sandbox environment.
  • You can find more technical information and troubleshooting steps in the Apple iOS Developer Library.
