GTM Kit Premium 1.3.0

Free

GTM Kit Premium 1.3.0 makes server-side tracking far easier to debug. You can now send a test event straight into your server container’s Preview panel on demand, without placing a real order, and a new filter gives developers full control over the outgoing webhook request.

Test your server-side setup without placing an order

Verifying a server-side (sGTM) container used to mean placing a real order and hoping the event showed up in Preview. The new Send test webhook to sGTM Preview tool, under Setup → Environment, removes that friction.

Pick any event type, send a synthetic sample or replay a real order, and attach your container’s Preview token so the event lands in the Preview/Debug panel on demand. The container’s response is shown inline, so you can confirm the payload, the destination, and the tag’s reaction in one place.

For the times you need to watch real traffic flow through Preview, an optional developer toggle can surface live orders in the Preview panel. It is self-expiring: it disarms automatically when the Preview token expires, so it can never be left on and break live tracking.

The Preview tool lives in the GTM Kit settings interface and needs GTM Kit core 2.16.4 or later. On older core the control stays hidden; everything else in this release works unchanged.

Bug fix: Template Assistant with a premium service

Generating a GTM container from the Template Assistant with a premium service selected (such as Server-Side Webhooks – GA4) now works. The request is sent to the licensed template endpoint with your license key, so the premium service is recognised as part of your plan instead of being rejected with a generic error.

Developer notes

  • New filter gtmkit_webhook_request_args lets you add headers (such as the sGTM Preview token) or otherwise reshape outgoing server-side webhook requests, without patching core.

Upgrade notes

No configuration changes are required. The Preview tool appears under Setup → Environment once you are on GTM Kit core 2.16.4 or later; there is no minimum-core change in this release.
