How ShareASale tracking fits together
Classic ShareASale links run through shareasale.com/r.cfm (or m.cfm / u.cfm) with your user ID (u), the merchant ID (m), and optionally a urllink deep-link destination. On click, ShareASale sets its sscid tracking cookie and redirects.
With the Awin merger, merchants progressively move to Awin’s infrastructure. Old ShareASale links for a migrated merchant may redirect without crediting you, or land on a "merchant not found" page.
