Querying Device Information for Shoppers with Purchases
If you are sending purchase events to Google Analytics 4 via the Measurement Protocol API, you cannot directly send geolocation or user device parameters to Google for the purchase.
However, if you're sending page_view events client-side, and are stitching together the server-side purchase event tracking before sending to the Measurement Protocol API, you can use simple session stitching to build this report.
See the SQL script below. Update the FROM statement with your Google BigQuery dataset ID.
