Push Subscription

To send push notifications to website visitors, users must first allow Push Notification Permission in their browser.
If they deny the permission request, push messages cannot be delivered to them.

By installing the JavaScript SDK provided by Vivoldi on your website, a browser popup requesting push permission will automatically appear upon visit.
If the user grants permission, their subscription data will be saved on the Vivoldi server,
and you can view it on the [Push Messages → Website Push Delivery] page in the dashboard.

For example, if 100 users allow notifications, the dashboard will display a list of 100 subscription records.
When you send a push message, it will be delivered to all users on this list.

Insert the following script inside the <head>...</head> section:

example.html 
<html>
<head>
<title>example page</title>
<script src="https://opencdn.vivoldi.com/js/webpush.min.js?v=202507301"></script>
<script>
const apiKey = 'oc3w9m4ytso9mv5e8yse9XXXXXXXXXX';
// Public Key of the domain registered on the “Push Message -> Domain Management” page.
const publicKey = 'XXXXXYTRlpG8mXXXXXiuBZ6BtjyOfgPsDArFYWF2PxZbY4egmDNias1gEfN_5wftScr39K8BbcjXXXXX';
const params = {apiKey:apiKey, publicKey:publicKey};
// Display notification permission pop-up (the pop-up will not appear if permission has already been granted)
webpush.register(params);
</script>
</head>

You can create your API Key on the Developer API page,
and you can find your publicKey by registering a domain on the Push Messages → Domain Management page.

Once everything is set up, create a new file named sw.min.js and upload it to the root directory of your website.
Example: https://example.com/sw.min.js

When accessing this URL, the JavaScript code should be displayed in the browser. This confirms that notifications will work correctly.
Copy and paste the code below into the newly created sw.min.js file.
