Knowing what URL a payment has originated from outside Shopify

Hi,

I have embedded a button on a WordPress site [different URL].

I want to know what page a purchase is initiated from on the Wordpress site.

In the purchase button > add to cart process the page is redirected to Shopify and the Shopify URL for processing.

Do payments have an identifier to know what page the purchase was initiated [add to cart].

Is there any information in the data of a successful purchase that can identify the original URL?

Any help is much appreciated,

Thanks!
