In order to schedule push notifications to your users’ devices, their devices need to be subscribed into the system. You can apply the following JavaScript code in your web app page, with this, the device will be automatically subscribed to the system when your users access to this web app page.

OR, you can manually subscribe the user’s device using our API service if you already know the user’s device UUID and device token. Scroll further down to know the steps to connect with our API service.

JavaScript code example

<script>
jQuery(function($){
    var web_data = [{

    }];
    window.top.ReactNativeWebView?.postMessage(JSON.stringify(web_data));
