Stape Shopify App - Send Test Webhook - Refund - 400 Status Code

Hey there!

I’m looking to send refund events to GA4 from Shopify and I have implemented Stape sGTM for GA4 on a pro account.

When I activate webhooks (I only want to use it for refunds), save and Send a test webhook - i get an empty/400 status request showing in my server GTM preview (manual requests enabled in powerups)

Could you please check and see if I’m doing something wrong and if this is a correct way to implement refund events for shopify with Stape.

This is what i see in preview:

Thanks in advance for your help!

and this is what i have in the app:

Update: it looks like my setup wasn’t complete as I didn’t configure the Data Client for the sGTM to claim the webhook requests. I’ve done it now and I can see those events coming through correctly:

Can you please point me to the info on setting up Refund event (if there’s any)

  • do i just set up a GA4 event tag in sGTM and send it to GA4 via measurement ID ?
  • and setup variables to populate parameters of the event based on the event data that comes through via webhook ?

Also for some reason I see both purchase and refund requests although i have only refund enabled in the app. I the purchase event is sent via webhook would it impact the normal ecommerce event i send from web GTM?
