The GA4 Affiliation parameter is a customizable field in Google Analytics 4 used to track the association of transactions or events with specific affiliations or partner programs.

This parameter is critical for businesses that rely on affiliate marketing, as it provides insights into which affiliates are driving sales and how effective those partnerships are.
