Connect Google Tag Manager
Connect GTM and the AI looks through your container's tags, triggers, and variables to check your setup and suggest improvements. Changes happen in two steps: save a GTM draft, then publish.
What you need
A Google account with access to the GTM account and container
How to connect
On your workspace's Data sources page, click Connect on the Google Tag Manager card.
Click Sign in with Google to sign in, then check the Google Tag Manager permission on the consent screen.
Choose a GTM account, then select the container to connect.
Examples
“List the conversion tags set up in this container.”
“Check the trigger conditions on our GA4 event tags.”
“Check whether any tags fire more than once.”
Troubleshooting
It says I need to check a permission
You moved on without checking Google Tag Manager on the Google consent screen. The connection won't work if you skip it. Sign in again and check that item.
The container list is empty
Either the selected GTM account has no containers, or the Google account you signed in with doesn't have access to them. Ask your GTM admin for access to the account and container.
The sign-in window doesn't open
Your browser is blocking pop-ups. Use the pop-up blocked icon in the address bar to allow pop-ups for this site, then try again.
It says the sign-in window was closed or timed out
You closed the window before finishing sign-in, or sign-in took too long. The connection just wasn't saved, and nothing else was affected, so start over from the beginning.
