Hash with data, which can be sent with publish method call and trigger remote notifications for specified platforms.

Other Examples

Generate simple notification payload for FCM and APNS

let builder = PubNub.notificationPayload('Chat invitation',
'You have been invited to \'quiz\' chat');
builder.sound = 'default';

console.log(JSON.stringify(builder.buildPayload(['apns', 'fcm']), null, 2));

Output

{
"pn_apns": {
"aps": {
"alert": {
"body": "You have been invited to 'quiz' chat",
"title": "Chat invitation"
},
"sound": "default"
}
},
"pn_gcm": {
"notification": {
"body": "You have been invited to 'quiz' chat",
"sound": "default",
"title": "Chat invitation"
show all 18 lines

Generate simple notification payload for FCM and HTTP/2-based APNs (default configuration)

let builder = PubNub.notificationPayload('Chat invitation',
'You have been invited to \'quiz\' chat');
builder.apns.configurations = [{ targets: [{ topic: 'com.meetings.chat.app' }] }];
builder.sound = 'default';

console.log(JSON.stringify(builder.buildPayload(['apns2', 'fcm']), null, 2));
Output
{
"pn_apns": {
"aps": {
"alert": {
"body": "You have been invited to 'quiz' chat",
"title": "Chat invitation"
},
"sound": "default"
},
"pn_push": [
{
"targets": [
{
"environment": "development",
"topic": "com.meetings.chat.app"
show all 29 lines

Generate simple notification payload for FCM and HTTP/2-based APNs (custom configuration)

let configuration = [
{
collapseId: 'invitations',
expirationDate: new Date(Date.now() + 10000),
targets: [{ topic: 'com.meetings.chat.app' }]
}
];
let builder = PubNub.notificationPayload('Chat invitation',
'You have been invited to \'quiz\' chat');
builder.apns.configurations = [configuration];

console.log(JSON.stringify(builder.buildPayload(['apns2', 'fcm']), null, 2));

Output

{
"pn_apns": {
"aps": {
"alert": {
"body": "Chat invitation",
"title": "You have been invited to 'quiz' chat"
}
},
"pn_push": [
{
"collapse_id": "invitations",
"expiration": "2019-11-28T22:06:09.163Z",
"targets": [
{
"environment": "development",
show all 29 lines

Example above show how to create notification payload which APNS will try to redeliver few times (if devices not active) and give up after 10 seconds since moment when it has been scheduled.

Additionally this invitation notification will be grouped along with other invitation notifications (using provided collapse_id as group identifier) and shown as one in notification center.

Returns

Configured and ready to use NotificationsPayload instance.
