Callbacks
Callbacks are useful for understanding the lifecycle stages of WebEngage messages. All WebEngage callbacks are called on the main thread.
New Session Started
This callback is invoked when a new session is started by our web SDK.
webengage.onSessionStarted(function(){
//CALLBACK LOGIC GOES HERE
})
On-site Notification Callbacks
Notification Opened
This callback is invoked when the on-site notification is opened.
webengage.notification.onOpen(function (data) {
if (data.notificationId === '_NOTIFICATION_ID_') {
//CALLBACK LOGIC GOES HERE
}
});
The callback data Object in the above call looks like below.
{
"notificationId": "173049892",
"licenseCode": "311c48b3",
"type": "notification",
"title": "Check out the new pricing",
"event": "open",

"jsessionid" : [ "CB300FEC898236FF9E5A181E468CA6BC" ]
}
}
Notification closed
This callback is invoked when the on-site notification is closed.
webengage.notification.onClose(function (data) {
if (data.notificationId === '_NOTIFICATION_ID_') {
//CALLBACK LOGIC GOES HERE
}
});
The callback data Object in the above call looks like below.
