OneSignal stopped supporting new apps from using Blogger, Bubble, Squarespace, Webflow, Weebly, Wix, HTTP sites, and website builders that don't support uploading Service Workers to a server (which are required for web push).
We used to provide a workaround subdomain like
https://LABEL_HERE.os.tcso we would host the Service Worker files for you, but this isn't going to be supported anymore for several reasons, the most important being:
- This doesn't work for iOS Web Push
- It provides a bad User Experience for your users
- Chrome is making a change detailed in their storage partitioning plans / CHIPS which when enabled prevents our SDK from checking unsubscribe stats when using the
If you currently use the the os.tc subdomain, you can continue to use it but will no longer be able to prompt for push notifications. Your existing subscriptions will continue to receive notifications. Starting September 8th, Chrome's change will prevent users from being able to unsubscribe when they visit the
https://LABEL_HERE.os.tc/unsubscribepage. They will need to unsubscribe from the browser notification settings.
Sorry for the inconvenience. We know a lot of people want this. Especially for blogger, hopefully the Google Team will support this someday: Is it possible that I can build progressive web app for my Blogger blog
If you use one of these types of site builders, you may be able to work around this by following our Typical Website setup and put a CDN in front of your domain to host the
OneSignalSDKWorker.jsService Worker file. But this is quite technical and we don't have any guidance on how to setup the CDN.
OneSignal supports sending web push notifications from a variety of different web technologies. Select Weebly to continue:
Once you've selected Weebly as your integration, you must fill out information about your site.
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.
www.example.com), 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
example.com are redirected to
www.example.com), so that all your traffic only goes to one.
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.
Enter a link to an icon file that is at least 80x80 pixels. Recommended size is 192x192. The file must be
Weebly 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.
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.
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.
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.
Optional: Most sites will not have to edit anything in Advanced options. See Web Push Advanced Options to learn more about each option.
Once you've completed steps 1-5, click 'Save' to save your configuration.
Next, you'll need to add OneSignal to your site by following step 6.
To enable OneSignal on your Weebly site, you will need to copy the code from Web Push Settings.
In your Weebly website editor, find your "Embed Code" element in your side panel under "BASIC".
Click and drag the element to an area of each page that you want to include OneSignal.
Click inside the element where it says "Click to set custom HTML" and "Edit Custom HTML".
Paste in the OneSignal code you copied above.
After clicking out of the "Embed Code" editor, you should see the OneSignal bell in the bottom right corner.
Continue these steps on each page you would like OneSignal to be used.
Publish your site and you are good to go!
You're all set up! See our Web Push Prompts page as well.
