You can register callback functions which will get executed once the user gets successfully subscribed/fails to get subscribed to push notifications. The same is pushed into the global _pcq queue. Refer to the syntax below:
Successful Subscription CallBack
Parameters:
- subscriptionSuccessCallback: Command to register the callback function to be executed when the user gets successfully subscribed to push notifications.
- callbackFunctionName: This is the name of the callback function. We will return the subscriberId as a parameter to this callback function and another object with two parameters:
i) status: String with value as 'SUBSCRIBED' or 'ALREADYSUBSCRIBED'
ii) message: String which denotes whether user is a new subscriber or whether user was already previously subscribed.
Refer to the syntax below:
_pcq.push(['subscriptionSuccessCallback', callbackFunctionName]);
window._pcq = window._pcq || [];
_pcq.push(['subscriptionSuccessCallback',callbackFunctionOnSuccessfulSubscription]); //registers callback function to be called when user gets successfully subscribed
function callbackFunctionOnSuccessfulSubscription(subscriberId, values) {
console.log('User got successfully subscribed.');
console.log(subscriberId); //will output the user's subscriberId
console.log(values.status); // SUBSCRIBED or ALREADYSUBSCRIBED
console.log(values.message) // 'User has subscribed to push notifications.' or 'User is already subscribed to push notifications.'
console.log('Now you may run code which should be executed once user gets successfully subscribed.');
}
Subscription Failure CallBack
Parameters:
- subscriptionFailureCallback: Command to register the callback function to be executed when the subscription fails.
- callbackFunctionName: This is the name of the callback function. We will return an object with two parameters.
i) status: String with value as 'BLOCKED', 'UNSUBSCRIBED' or 'CANCELLED'
ii) message as to why the subscription failed.
Refer to the syntax below:
_pcq.push(['subscriptionFailureCallback', callbackFunctionName]);
window._pcq = window._pcq || [];
_pcq.push(['subscriptionFailureCallback',callbackFunctionOnFailedSubscription]); //registers callback function to be called when user gets successfully subscribed
function callbackFunctionOnFailedSubscription(values) {
console.log('User could not get subscribed to push notifications');
console.log(values.status); // BLOCKED , UNSUBSCRIBED or CANCELLED
console.log(values.message) // 'User has blocked push notifications.', 'User has unsubscribed from push notifications', 'No change in subscription. Child window was closed.' or 'User has closed the notifications opt-in.'
console.log('Now you may run code which should be executed once user subscription fails');
