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

4. Delivery of the push notification to mobile devices by the OS vendor

Push Notification Flow for Customers

Salesforce sends the message to the users specified in the send call of the Apex Messaging.PushNotification 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.

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

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.

The Salesforce connected app enables you to provide the registration certificate or token of your mobile client app so that Salesforce

can send push notifications. Also, the connected app provides the unique API name that identifies the mobile app to send notifications

to.

To run a quick test of your push notification setup, use the Send Test Notification page. The Send

Test Notification page lets you troubleshoot round-trip push notifications in a synchronous

mechanism without having to configure Apex or REST calls. It can also provide insights into what’s

going on behind the scenes in the asynchronous environment of real-world push notifications.

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.

For Android GCM push notifications, you can select the Dry Run option to test your GCM setup.

This option sends the notification to the GCM server but does not forward it to a device.

Each push attempt returns a status message that indicates success or failure. See Error Messages

for Push Notifications for explanations of messages. For additional information, see:

•developer.apple.com for information on Apple APNS push notifications.

•developer.android.com for information on GCM for Android push notifications.

To reach the test page:

1. In Setup, enter Apps in the Quick Find box, then select Apps.

2. Click the name of your connected app.

3. Click Send test notification next to Supported Push Platform. This link appears only if you’ve configured your connected app to

support mobile push notifications.

Important: Successful test push notifications apply against the push notification daily limits for your organization.

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.

Testing Your Connected App Push ConfigurationSteps for Implementing Mobile Push Notifications

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).

IN THIS SECTION:

Enable Push Notifications in a Salesforce Mobile SDK Android App

Enable Push Notifications in a Salesforce Mobile SDK iOS App

Enable Push Notifications in a Salesforce Mobile SDK Hybrid App

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):

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

•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

Step 3. Configure Your Mobile SDK AppSteps for Implementing Mobile Push Notifications

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);

}

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

Enable Push Notifications in a Salesforce Mobile SDK iOS AppSteps for Implementing Mobile Push Notifications

failure:self.initialLoginFailureBlock];

return YES;

}

If registration succeeds, Apple passes a device token to the

application:didRegisterForRemoteNotificationsWithDeviceToken: method of your AppDelegate

class.

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

•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);

}

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.

Enable Push Notifications in a Salesforce Mobile SDK Hybrid

App

Steps for Implementing Mobile Push Notifications

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.

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);

Step 4. Using Apex Triggers to Send Push NotificationsSteps for Implementing Mobile Push Notifications

}

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

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.

Step 5. Packaging Components for Customer OrganizationsSteps for Implementing Mobile Push Notifications

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.

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.

Maximum notifications per app per dayMobile application type

50,000Provided by Salesforce (for example, Salesforce1)

35,000Developed by your company for internal employee use

5,000Installed from the AppExchange

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.
