Click on New Project:
Choose a name for your project and select Website as a platform then click Create:
Already have a project?
Just add the Website platform to any existing project by going to Settings, selecting the first tab named after your project and clicking Edit. You'll be presented a form that lets you add a platform.
Enter website information:
Enter the name of your website. This name might be displayed when users subscribe to push notifications.
Enter the base URL of your site (e.g.
https://example.com). This will be the default URL users will be redirected to when they click on a notification.
If your site is accessible from both
www. and non-
www. URLs (e.g.
www.example.com) we recommend you redirect traffic to one of the URLs and use that to fill-in the URL field.
Enter the URL to your website icon or choose a file from your computer. Your website icon will be displayed in notifications. It should be a square image file. Prefer HTTPS.
My site doesn't have HTTPS
If your site doesn't have HTTPS, check this box. Please note that HTTPS certificates are FREE these days, and very easy to install. Take a look at let's encrypt.

Choose an HTTPS notification domain.
Your push notification domain will be displayed in every notification you send:
In this example, the notification domain is
When users subscribe to push notifications, they grant your domain the permission to send them push notifications. When you change the push notification domain, users have to subscribe again!
For these reasons, it is especially important to choose the right push notification domain from the start.
Using your own domain
This is the best option. It is only available for HTTPS websites. If your website does not support HTTPS, or if you can't upload SDK files, use
If your site does not support HTTPS, or if you can't upload SDK files, that's your only option.
