Adding the JavaScript snippet to your page

Standard setup

The snippet below allows you to:

It does not include the Safari setup object, which will be automatically generated on the dashboard depending on your configuration.

To get a personalized tag, including your own setup information (as API keys or safari set-up object), click on the Get the code button (⚙️ Settings → Push settings → Website Push configuration).

Custom alert setup details

Using the snippet above, the custom alert will only be displayed on Mozilla Firefox and Safari on MacOS. The native opt-in request will be displayed on other browsers.

Where to implement the JavaScript snippet?

Optimize performance

The tag should be implemented at the end of the body, so it doesn't block any other script.

Note that browsers directly manage the download and installation of the service worker asynchronously so it doesn't affect performance.

Trigger the subscription request at the right moment

In most cases, the JavaScript tag should be implemented on every page of your website that belong to the same domain. It allows users to be exposed to the opt-in request regardless of the origin of the traffic (organic, newsletter...). Alternatively, you can also choose to scenarize the opt-in request, after users perform a specific action.

Domains and subdomains management

Usually, the JavaScript tag should only deployed on your main domain (no other domain or subdomain) to eliminate risks of duplicate notifications.

If you want to integrate Batch on several domains or subdomains, check the dedicated section of the documentation Domains and subdomains management.
