Choose an HTTPS notification domain.


About the push notification domain

Your push notification domain will be displayed in every notification you send:

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

Using a subdomain

If your site does not support HTTPS, or if you can't upload SDK files, that's your only option.
