Awin parameter
What is the ued parameter?
ued is Awin's url-encoded destination. ued carries the exact page the visitor should land on, URL-encoded inside the Awin link. It is also the key to auditing: decode ued and you can verify the destination page independently of the tracking hop — which is exactly how Afterlink checks Awin deep links.
Where it appears
In the affiliate link you publish
Example
https://www.awin1.com/cread.php?...&ued=https%3A%2F%2Fmerchant.com%2FproductIf ued is missing
Without ued, an Awin deep link falls back to the program’s default landing page — your visitor lands on a generic page instead of the product you promoted.
How Awin tracking fits together
A standard Awin deep link runs through awin1.com/cread.php. The awinmid parameter identifies the merchant, awinaffid identifies you, and ued carries the URL-encoded destination page. When a visitor clicks, Awin registers the click server-side, sets its tracking cookie, and redirects to the merchant with an awc click ID appended.
Because the destination is embedded inside the link, an Awin link can fail in two independent places: the Awin hop (program closed, merchant left) and the destination page (product removed, URL changed). A correct health check has to verify both.
