Google Tag Manager

Add cside to your website using a Custom HTML tag in Google Tag Manager for quick testing.

GTM installation is for testing only

GTM does not guarantee script load order, so other scripts may execute before cside can intercept them. For production, use direct script installation to ensure cside loads first.

Install cside in Google Tag Manager with a Custom HTML tag. This is the fastest way to try cside on your site without touching any code.

Setup

Create a Custom HTML tag

In Google Tag Manager, go to Tags > New, click Tag Configuration, and select Custom HTML.

Paste the script

Copy the snippet below and paste it into the HTML field. Replace [your-team-id] with your team ID from the cside dashboard.

<script type="text/javascript" src="https://[your-team-id].csidetm.com/client.js" referrerpolicy="origin"></script>

Set trigger to All Pages

Under Triggering, select All Pages so cside monitors every page on your site.

Publish

Save the tag and publish your GTM container. Visit your website - you should see script traffic appear in the cside dashboard within seconds.

Moving to production

When you’re ready for production, switch from GTM to a direct integration method. This guarantees cside loads before any other scripts on the page:
