How to set up OneSignal Web Push notifications on Squarespace sites

This guide will walk you through how to set up web push on Squarespace. If you do not use Squarespace, or wish to write custom code, please go to Web Push Quickstart.

At any time to get back to setup, go to App Settings and click Configure for the Google Chrome platform (instructions for Safari are here).


As of December 1, 2017, Squarespace requires customers have Premium plans to be able to add custom code to your site, which is required for web push.

Step 1. Choose Integration

OneSignal supports sending web push notifications from a variety of different web technologies. Select Squarespace to continue:

Step 2. Site Setup

Once you've selected Squarespace as your integration, you must fill out information about your site.

Enter Site URL

Most users just enter their base site URL for this field (e.g.

If your site is accessible from both www & non-www links (e.g. AND, please only enter the URL that you wish to send push notifications from. We recommend redirect traffic from one to the other (e.g. users that visit are redirected to, so that all your traffic only goes to one.

Auto Resubscribe

Recommended: This feature is only for HTTPS sites and if you do not select "My site is not fully HTTPS". This allows users to automatically resubscribe upon returning to the site without being prompted if they clear their browser cache or if you are transferring to OneSignal from another push provider.

Default Notification Icon URL

Enter a link to an icon file that is at least 80x80 pixels. Recommended size is 192x192. The file must be .png, .jpg, or .gif.

Choose a Label

Squarespace implementations must choose a unique label to be displayed in your notifications. For example, the below image shows notifications are coming from

Warning: You can only change your label if you have less than 100 web users. Once you have 100+ web users, this setting is disabled.


How does OneSignal work differently with HTTP sites?

What if my site is in a subfolder?

Why does my site require a label?

Why can't I change my label?

Step 3. Permission Prompt Setup

To send push notifications to users, you first must ask them for permission using a Prompt. You must have at least one Prompt on your site for web push to work. Click Add a Prompt to open the permission prompt selector.

Permission Prompt Editor

In the Permission Prompt Editor, you can select which prompts you wish to use, and style them as you like. Once you have edited the prompt to your liking, click Save.

Subscription Bell - a small icon at the corner of your page that users can interact with to subscribe

Slide Prompt - a small modal that comes from the center of the page and asks if users are interested in signing up.

HTTP Pop-Up Prompt (HTTP-only) - a pop-up window that appears after other prompts that is required for HTTP sites.

Custom Prompts - create your own links or buttons as prompts.

Step 4. Welcome Notification

Optional: Welcome notifications an optional way to thank users after subscribing to your site. Users will see a welcome notification as soon as they subscribe. You can edit or disable them here.

-## Step 5. Advanced Options

Optional: Most sites will not have to edit anything in Advanced options. See Web Push Advanced Options to learn more about each option.


Site Configured
