MOBILE PUSH NOTIFICATIONS OVERVIEW
Mobile push notifications allow Force.com mobile application developers to easily push notifications to their users’ mobile devices when business events occur in the customers’ organizations.
Salesforce push notifications use the connected app framework. They support customer apps built in-house and partner or ISV apps installed via managed packages.
Business events in the customer’s organization are trapped using Apex triggers that specify the notification message payload and recipient users. The push feature hands off notifications to services operated by device OS vendors, such as Apple or Google, for subsequent delivery to customers’ mobile devices.
To handle events that Apex triggers can’t catch, the push notifications resource of the Chatter REST API provides an alternative mechanism.
Note: These instructions do not apply to Marketing Cloud apps. To implement Marketing Cloud MobilePush notifications, see developer.salesforce.com/docs/atlas.en-us.mc-sdks.meta/mc-sdks/mobile-push-sdk.htm
.
IN THIS SECTION:
Push Notification Registration and Flow
To enable push notifications, you register with several different entities and configure the required settings.
Push Notification Registration and Flow
To enable push notifications, you register with several different entities and configure the required settings.
Entities involved when sending a push notification include:
•
The OS vendor that delivers the notification to devices
•
The Salesforce organization that sends the notification
•
The mobile devices that receive and display the notification
This is an outline of the registration process for developers.
1. Register with the mobile OS vendor, such as Apple or Google, for push service.
2. Create a connected app in Salesforce to upload the push credentials, such as the iOS
.p12
certificate or the Android token.
3. Enable the mobile client app to handle push notifications using the Salesforce Mobile SDK.
4. Write Apex triggers to send push notifications when certain events occur on Salesforce records.
5. (For partners only) For partners who are developing the push notification triggers for other customer organizations, this additional step should be performed.
Create a managed package containing the connected app and Apex triggers. Distribute this package to customer organizations.
The following figure illustrates the complete push notification flow for customers who develop their own mobile apps and Apex triggers.
The flow consists of the following sequence of events:
1. Developer registration with the OS vendor (Apple in this figure)
2. Connected app setup in Salesforce
3. Sending the push notification via the trigger from the Salesforce organization

class.
This next figure illustrates the complete push notification flow for partners and customers. In addition to the flow represented in the previous diagram, this flow includes steps for customers who have installed the partner’s package. It includes purchase of the partner app, and installation of the partner’s package to get the connected app and the Apex triggers. The last few steps of sending and delivering the push notification are similar to the previous flow.

STEPS FOR IMPLEMENTING MOBILE PUSH NOTIFICATIONS
To implement mobile push notifications, you configure each of the participating technologies.
IN THIS SECTION:
Step 1. Developer Registration with Mobile OS Vendors
This step asks the OS vendor to be prepared to handle Salesforce push notifications sent to your app. Developer registration also provides some information you’ll need to finish configuring your Salesforce connected app.
Step 2. Creating a Connected App
Once you’ve registered your mobile app with the OS vendor’s push service, the next step is to create a connected app in Salesforce.
Step 3. Configure Your Mobile SDK App
In your Mobile SDK app, implement push notification protocols required by Salesforce and the device OS provider.
Step 4. Using Apex Triggers to Send Push Notifications
After registering with the mobile OS vendor for push notification service and creating a connected app, you can send push notifications to a mobile client app using Apex triggers.
Step 5. Packaging Components for Customer Organizations
To distribute the Apex triggers and the connected app to customers, partners can create a managed package.
Step 1. Developer Registration with Mobile OS Vendors
This step asks the OS vendor to be prepared to handle Salesforce push notifications sent to your app. Developer registration also provides some information you’ll need to finish configuring your Salesforce connected app.
To register your mobile client app, follow the process for your target mobile OS.
Android Registration
When developing an Android app that supports push notifications, remember these key points:
•
You must be a member of the Android Developer Program.
•
You can test GCM push services only on an Android device with either the Android Market app or Google Play Services installed.
Push notifications don’t work on an Android emulator.
Salesforce sends push notifications to Android apps through the Google Cloud Messaging for Android (GCM) framework. See http://developer.android.com/google/gcm/index.html
for an overview of this framework.
To begin, create a Google API project for your app. Your project must have the GCM for Android feature enabled. See http://developer.android.com/google/gcm/gs.html
for instructions on setting up your project.
The setup process for your Google API project creates a key for your app. Once you’ve finished the project configuration, you’ll need to add the Key for Server Applications (API Key) from GCM to your connected app settings.
Note: Push notification registration occurs at the end of the OAuth login flow. Therefore, an app does not receive push notifications unless and until the user logs into a Salesforce org.

Steps for Implementing Mobile Push Notifications Step 2. Creating a Connected App
iOS Registration
When developing an iOS app that supports push notifications, remember these key points:
•
You must be a member of the iOS Developer Program.
•
You can test Apple push services only on an iOS physical device. Push notifications don’t work in the iOS simulator.
•
There are no guarantees that all push notifications will reach the target device, even if the notification is accepted by Apple.
•
Apple Push Notification Services setup requires the use of the OpenSSL command line utility provided in Mac OS X.
Before you can complete registration on the Salesforce side, you need to register with Apple Push Notification Services (APNS).
Registration with APNS requires the following items.
Certificate Signing Request (CSR) File
Generate this request using the Keychain Access feature in Mac OS X. You’ll also use OpenSSL to export the CSR private key to a file for later use.
App ID from iOS Developer Program
In the iOS Developer Member Center, create an ID for your app, then use the CSR file to generate a certificate. Next, use OpenSSL to combine this certificate with the private key file to create an appkey.p12
file. You’ll need this file later to configure your connected app.
iOS Provisioning Profile
From the iOS Developer Member Center, create a new provisioning profile using your iOS app ID and developer certificate. You then select the devices to include in the profile and download to create the provisioning profile. You can then add the profile to Xcode.
Install the profile on your test device using Xcode's Organizer.
When you’ve completed the configuration, sign and build your app in Xcode. Check the build logs to verify that the app is using the correct provisioning profile. To view the content of your provisioning profile, run the following command at the Terminal window:
security cms -D -i < your profile
>.mobileprovision

About the Send Test Notification Page
The Send Test Notification page uses information from your Apple Push Notification Service (APNS) or Google Cloud Messaging for Android (GCM) setup to configure a synchronous push mechanism.
You select a device to receive the push notification by entering a connection token string. If you don’t know the token string, you can use the Search tool to select from the list of devices that are registered for your connected app. The Search tool automatically displays the five most recently registered devices. You can also enter a user’s name to search for devices that are registered to that user.

Steps for Implementing Mobile Push Notifications Step 3. Configure Your Mobile SDK App
Send Test Push Notifications to APNS
To run a quick test of your push notification setup for Apple Push Notification Service (APNS), use the Send Test Notification page.
1. Enter a connection token string in the Recipient field, OR search for a recipient by clicking Search
, and then select one of the search results. By default, the Search results list displays the five devices most recently registered for your connected app.
a. To find other devices, enter a user name in the Search text box.
b. Click Go to generate a list of all devices currently registered under that user name.
2. Optionally, for Alert, enter an alert message or dictionary per Apple’s specifications.
3. For Badge, enter a badge number or
0
for no badge.
4. For Sound, enter the name of a sound file in the application bundle, or enter
default
to use the system default alert sound.
5. Optionally, to use a custom payload, enter your payload’s JSON value in the Custom Payload field.
6. Click Send to send the test push notification, or click Clear to reset the form.
Send Test Push Notifications to GCM for Android
To run a quick test of your push notification setup for Google Cloud Messaging for Android (GCM), use the Test Push Notifications page.
1. Enter a connection token string in the Recipient field, OR search for a recipient by clicking Search
, and then select one of the search results. By default, the Search results list displays the five devices most recently registered for your connected app.
a. To find other devices, enter a user name in the Search text box.
b. Click Go to generate a list of all devices currently registered under that user name.
2. For Payload, enter a JSON value that contains your message.
3. To send the push notification to the GCM server only, select Dry Run.
4. Click Send to send the test push notification, or click Clear to reset the form.
Check a User's Mobile Push Registrations
From a User page in your organization, an administrator can easily check which of the user’s devices are currently registered for push notifications. Checking the registrations may help you troubleshoot push notification failures.
1. In Setup, enter
Users
in the
Quick Find
box, then select Users.
2. Select a user’s name from the Full Name column.
3. Under User Detail, click View next to Mobile Push Registrations.
Note: If a device you expected doesn’t appear in the list, it doesn’t necessarily mean that the device isn’t properly configured.
Mobile push registrations are volatile and depend on the device state as well as the mobile app state.
Step 3. Configure Your Mobile SDK App
In your Mobile SDK app, implement push notification protocols required by Salesforce and the device OS provider.
Follow the instructions for your target mobile platform (Android, iOS, or hybrid).

Enable Push Notifications in a Salesforce Mobile SDK Android App
1. Add an entry for androidPushNotificationClientId
.
a. In res/values/bootconfig.xml
(for native apps):
<string name="androidPushNotificationClientId">1234567890</string>
b. In assets/www/bootconfig.json
(for hybrid apps):
"androidPushNotificationClientId": "1234567890"
This example value represents the project number of the Google project that is authorized to send push notifications to Android devices.
Note: Behind the scenes, Mobile SDK automatically reads this value and uses it to register the device against the Salesforce connected app. Each time the user re-opens the app, Mobile SDK automatically renews the registration. This validation allows
Salesforce to send notifications to the connected app.
A device becomes unregistered if:
•
The app goes unused for an extended period of time
OR
•
The user logs out of the app
2. Create a class in your app that implements
PushNotificationInterface
.
PushNotificationInterface
is a
Mobile SDK Android interface for handling push notifications.
PushNotificationInterface
has a single method, onPushMessageReceived(Bundle message)
.
public interface PushNotificationInterface { public void onPushMessageReceived(Bundle message);
}
In this method you implement your custom functionality for displaying, or otherwise disposing of, push notifications.
3. In the onCreate()
method of your
Application
subclass, call the
SalesforceSDKManager.setPushNotificationReceiver()
method, passing in your implementation of
PushNotificationInterface
. Call this method immediately after the
SalesforceSDKManager.initNative() call.
@Override public void onCreate() { super.onCreate();
SalesforceSDKManager.initNative(getApplicationContext(), new KeyImpl(), MainActivity.class);
SalesforceSDKManager.getInstance().
setPushNotificationReceiver(myPushNotificationInterface);
}

Steps for Implementing Mobile Push Notifications Enable Push Notifications in a Salesforce Mobile SDK iOS App
Enable Push Notifications in a Salesforce Mobile SDK iOS App
Salesforce Mobile SDK for iOS provides the
SFPushNotificationManager
class to handle push registration. To use it, import
<SalesforceSDKCore/SFPushNotificationManager>
. The
SFPushNotificationManager
class is available as a runtime singleton:
[SFPushNotificationManager sharedInstance]
This class implements four registration methods:
- (void)registerForRemoteNotifications;
- (void)didRegisterForRemoteNotificationsWithDeviceToken:
(NSData*)deviceTokenData;
- (BOOL)registerForSalesforceNotifications; // for internal use
- (BOOL)unregisterSalesforceNotifications; // for internal use
Mobile SDK calls registerForSalesforceNotifications
after login and unregisterSalesforceNotifications at logout. You call the other two methods from your
AppDelegate
class.
1. Register with Apple for push notifications by calling registerForRemoteNotifications
. Place the call in the application:didFinishLaunchingWithOptions:
method.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{ self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
[self initializeAppViewState];
//
// Register with APNS for push notifications. Note that,
// to receive push notifications from Salesforce, you
// also need to register for Salesforce notifications in the
// application:
// didRegisterForRemoteNotificationsWithDeviceToken:
// method (as demonstrated below.)
//
[[SFPushNotificationManager sharedInstance] registerForRemoteNotifications];
[[SFAuthenticationManager sharedManager] loginWithCompletion:self.initialLoginSuccessBlock
failure:self.initialLoginFailureBlock]; return YES;
}
If registration succeeds, Apple passes a device token to the application:didRegisterForRemoteNotificationsWithDeviceToken:
method of your
AppDelegate class.
11
Steps for Implementing Mobile Push Notifications Enable Push Notifications in a Salesforce Mobile SDK iOS App
2. Forward the device token from Apple to
SFPushNotificationManager
by calling didRegisterForRemoteNotificationsWithDeviceToken
on the
SFPushNotificationManager
shared instance.
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:
(NSData*)deviceToken
{
//
// Register your device token with
// the push notification manager
//
[[SFPushNotificationManager sharedInstance] didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}}
3. Register to receive Salesforce notifications through the connected app by calling registerForSalesforceNotifications
.
Make this call only if the access token for the current session is valid.
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:
(NSData*)deviceToken
{
//
// Register your device token with the
// push notification manager
[[SFPushNotificationManager sharedInstance] didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
if ([SFAccountManager sharedInstance].credentials.accessToken
!= nil){
[[SFPushNotificationManager sharedInstance] registerForSalesforceNotifications];
}}
Note: Behind the scenes, Mobile SDK automatically reads this value and uses it to register the device against the Salesforce connected app. Each time the user re-opens the app, Mobile SDK automatically renews the registration. This validation allows
Salesforce to send notifications to the connected app.
A device becomes unregistered if:
•
The app goes unused for an extended period of time
OR
•
The user logs out of the app
4. Add the following method to log an error if registration with Apple fails.
- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:
(NSError*)error
{
NSLog(@"Failed to get token, error: %@", error);
}

Steps for Implementing Mobile Push Notifications Enable Push Notifications in a Salesforce Mobile SDK Hybrid
App
Enable Push Notifications in a Salesforce Mobile SDK Hybrid App
1. (Android only) If your target platform is Android:
a. Add an entry for androidPushNotificationClientId
. In assets/www/bootconfig.json
:
"androidPushNotificationClientId": "33333344444"
This value is the project number of the Google project that is authorized to send push notifications to an Android device.
2. In your callback for cordova.require("com.salesforce.plugin.oauth").getAuthCredentials()
, add the following code: cordova.require("com.salesforce.util.push").registerPushNotificationHandler( function(message) {
// add code to handle notifications
}, function(error) {
// add code to handle errors
}
);
Example: This code demonstrates how you might handle messages. The server delivers the payload in message["payload"]
.
function(message) { var payload = message["payload"]; if (message["foreground"]) {
// Notification is received while the app is in
// the foreground
// Do something appropriate with payload
} if (!message["foreground"]) {
// Notification was received while the app was in
// the background, and the notification was clicked,
// bringing the app to the foreground
// Do something appropriate with payload
}
}
Step 4. Using Apex Triggers to Send Push Notifications
After registering with the mobile OS vendor for push notification service and creating a connected app, you can send push notifications to a mobile client app using Apex triggers.
Push notification triggers use methods in the Apex
Messaging.PushNotification
and
Messaging.PushNotificationPayload
classes. The connected app in the Salesforce organization represents the mobile client app that will receive the notifications.
Important:
To send push notifications to a connected app, either of the following conditions must be met:
•
Apex triggers are added in the same organization in which the connected app is created.
•
Apex triggers are installed as part of a partner-provided managed package, along with the connected app.
13
Steps for Implementing Mobile Push Notifications Step 4. Using Apex Triggers to Send Push Notifications
Sample Apex Trigger
This sample Apex trigger sends push notifications to the connected app named
Test_App
, which corresponds to a mobile app on iOS mobile clients. The trigger fires after cases have been updated and sends the push notification to two users: the case owner and the user who last modified the case.
trigger caseAlert on Case (after update) { for(Case cs : Trigger.New)
{
// Instantiating a notification
Messaging.PushNotification msg = new Messaging.PushNotification();
// Assembling the necessary payload parameters for Apple.
// Apple params are:
// (<alert text>,<alert sound>,<badge count>,
// <free-form data>)
// This example doesn't use badge count or free-form data.
// The number of notifications that haven't been acted
// upon by the intended recipient is best calculated
// at the time of the push. This timing helps
// ensure accuracy across multiple target devices.
Map<String, Object> payload =
Messaging.PushNotificationPayload.apple(
'Case ' + cs.CaseNumber + ' status changed to: '
+ cs.Status, '', null, null);
// Adding the assembled payload to the notification msg.setPayload(payload);
// Getting recipient users
String userId1 = cs.OwnerId;
String userId2 = cs.LastModifiedById;
// Adding recipient users to list
Set<String> users = new Set<String>(); users.add(userId1); users.add(userId2);
// Sending the notification to the specified app and users.
// Here we specify the API name of the connected app.
msg.send('Test_App', users);
}
}
Sample Android Payload
The trigger sample uses
Messaging.PushNotificationPayload
to create a payload for an iOS notification. Unlike iOS,
Android doesn’t have special attributes or requirements for the payload; it just needs to be in JSON format. In Apex, you create the
14
Steps for Implementing Mobile Push Notifications Step 5. Packaging Components for Customer Organizations
Android payload as a MAP<String,ANY> object. The
Messaging.PushNotification
class handles conversion to JSON. Here is a sample Android payload.
Map<String, Object> androidPayload = new Map<String, Object>(); androidPayload.put('number', 1); androidPayload.put('name', 'test');
Step 5. Packaging Components for Customer Organizations
To distribute the Apex triggers and the connected app to customers, partners can create a managed package.
When customers install your managed package, they will be able to send push notifications to the connected app from their organizations when certain events occur on Salesforce records, such as updating records.
Note: Customers who install a managed package containing a connected app provided by a partner can’t write their own Apex triggers to send push notifications to the connected app. This is to safeguard the partner’s registration with the mobile OS vendor from abuse.
15
USING THE CHATTER REST API PUSH NOTIFICATION
RESOURCE (OPTIONAL)
If you prefer to send push notifications without looping through the Apex engine—in other words, if you just want to push a simple message from a connected app on one mobile device to another—use the Chatter REST API push notification resource. This resource is useful for sending notifications of events that occur outside of Salesforce and can be handled entirely within the mobile connected app. You can use this resource in any type of custom app: a native Mobile SDK app, a hybrid Mobile SDK app, or an HTML5 app.
The Chatter REST API resource establishes an HTTP session to send POST requests from the sending device to one or more receiving devices. This means that:
•
The sending app and the receiving apps must either be developed in the same organization or be installed from the same package.
•
Only the receiving apps are required to be registered for push notifications with Apple or Google.
•
Only the receiving apps are required to implement the Salesforce Mobile SDK push notification protocols.
•
Each app requires a connected app, but only the receiving connected apps must be configured for push notifications.

PushNotification Class
PushNotification
is used to configure push notifications and send them from an Apex trigger.
Namespace
Messaging
Example
This sample Apex trigger sends push notifications to the connected app named
Test_App
, which corresponds to a mobile app on iOS mobile clients. The trigger fires after cases have been updated and sends the push notification to two users: the case owner and the user who last modified the case.
trigger caseAlert on Case (after update) { for(Case cs : Trigger.New)
{
// Instantiating a notification
Messaging.PushNotification msg = new Messaging.PushNotification();
// Assembling the necessary payload parameters for Apple.
// Apple params are:
// (<alert text>,<alert sound>,<badge count>,
// <free-form data>)
// This example doesn't use badge count or free-form data.
// The number of notifications that haven't been acted
// upon by the intended recipient is best calculated
// at the time of the push. This timing helps
// ensure accuracy across multiple target devices.
Map<String, Object> payload =
Messaging.PushNotificationPayload.apple(
'Case ' + cs.CaseNumber + ' status changed to: '
+ cs.Status, '', null, null);
// Adding the assembled payload to the notification msg.setPayload(payload);
// Getting recipient users
String userId1 = cs.OwnerId;
String userId2 = cs.LastModifiedById;
// Adding recipient users to list
Set<String> users = new Set<String>(); users.add(userId1);

}
} users.add(userId2);
// Sending the notification to the specified app and users.
// Here we specify the API name of the connected app.
msg.send('Test_App', users);

Push Notification Limits
Push notification limits apply to test push notifications as well as to production notifications.
Note: The limits described here are for core Salesforce push notifications. They do not apply to Marketing Cloud MobilePush notifications. For further information on Marketing Cloud usage, see developer.salesforce.com/docs/atlas.en-us.mc-sdks.meta/mc-sdks/mobile-push-sdk.htm
.
The maximum push notifications allowed for each mobile app associated with your Salesforce org depends on the type of app.
Mobile application type
Provided by Salesforce (for example, the Salesforce app)
Developed by your company for internal employee use
Installed from the AppExchange
Maximum notifications per app per day
50,000
35,000
5,000
Only deliverable notifications count toward this limit. For example, consider the scenario where a notification is sent to 1,000 employees in your company, but 100 employees haven’t installed the mobile application yet. Only the notifications sent to the 900 employees who have installed the mobile application count toward this limit.
Each test push notification that is generated through the Test Push Notification page is limited to a single recipient. Test push notifications count toward an application’s daily push notification limit.
