Last updated: 18 October 2021. Peview works now with the proxied container even if the container ID is overridden..
While server-side tagging already has a wonderful built-in Client for proxying the Google Tag Manager container via your own first-party domain, it’s not perfect.
The main issues are that it doesn’t let you delimit access on a per-origin basis, so requests for the allowlisted container IDs can be sent from anywhere, and that it doesn’t let you freely choose the path via which the container ID is loaded.
