Shopify Stape.io App

So i’m installing my GTM through Customer Events. It’s working fine, but it’s pretty annoying not being able to preview and debug them through GTM. I’m wondering if I install GTM through Stape.io app, will I be able to see the tags firing in GTM preview?

When using the Stape app to add GTM previews will work before a checkout. This is not tech possible on checkout pages.

Can we add custom events into the dataLayer to be captured by GTM previews through Stape app

If you are adding a data layer via customer pixel - your GTM should also work in it. Since customer events exist in a separate frame - data layer events exist only in that frame and are not available to other frames, i.e. if you have GTM running in one frame (e.g. via Stape app) and you send data layer events in another frame - they will not be available.
