The Google Merchant Center Lookup variable retrieves and enhances product data by querying a Google Merchant Center account.
It's especially useful for adding product details like categories or attributes when sending data to other systems, such as Google Ads or Google Analytics, through a server-side GTM container.
Initial development was done by Lars Friis.
The Google Merchant Center Lookup variable for GTM Server is developed and maintained by the Stape Team under the Apache 2.0 license.
