Verify your setup
You can verify if you set everything up correctly by navigating to https://yourdomain.com/. If you see a push notification opt-in request, everything is working! That’s all, your website is now ready to send push notifications!
If you do not see an opt-in request, you can check whether the code snippet and javascript file were correctly added. Navigate to https://yourdomain.com/sw.js. Here you should find the following text:
importScripts('https://storage.googleapis.com/push-pro-java-scripts/pushpro-sw.js');
Next up, you can verify whether you correctly added the code snippet. On https://yourdomain.com/, right-click anywhere on the website and select “Page Source”. Here, you should find the following text:
<script></script>
window.__pushpro = {
site_uuid: "your-unique-identifier",
}
