Additional Scripts only if customer visited certain page before

Technical Q&A
1

Hello,

we are required to integrate a pixel for an affiliate platform. This pixel should fire on the thank-you page but ONLY IF the customer visited a certain landing page before (www.ourpage.com/landingpage/)

(1) What would be the best method to state this condition in the thank-you page scirpts?

The URL that is called is https://domain.com/?param=value&sovReqToken=1095752fb409-457a-af14-17a09e6be522

(2) How can we store the sovReqToken and call it later on the thank-you page script?

Attached is the manual - maybe it helps.

System: NOT Shopify plus

Thanks a lot in advance.
