PushNotification Class
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);
}
