Webhook & GTM Custom HTML Script

Hi there!
I've run into some trouble using the Webhook URL with a custom HTML script in Google Tag Manager. The script used to work in a similar way, but no I can't get it to work. Is there anyone who can take a quick look at my custom HTML Tag and maybe spot a mistake? I only want to catch one value with the hook (see image attached).

thanks in advance!
Sebastian

Hey @SVsa

Currently xhr function is not compatible on the system so instead of that kindly use the fetch function, which you can redirect in the Postman application.

Please refer to the following API documentation for the same.

Thank you so much! It's working!
