GTM is a tag management system that deploys and manages measurement code without touching site source. Web container runs in the browser; sGTM runs on a server you control.

| Server Container (sGTM) | Server-side tag processing on your infrastructure |
| Tag Manager API v2 | Programmatic container management — CI/CD, bulk ops |
| Container ID format | GTM-XXXXXXXX — found in GTM UI > Admin |
