does NATS use linkcode or cookie tracking?
 

i always thought most programs like Juggcash with NATS need the affiliate to send an immediate sale since its directly linked with ur linkcode

whereas many other affiliate program software have a 15 day cookie limit..

is this true?

The cookie time is set on a per-site basis; it's a config option. Many places use the default value of 31536000; 365 days. Technically, you're getting screwed for 4 hours every leap year.

Edit: So to answer your question: NATS uses link AND cookie tracking, and the default cookie is more than generous.

thnx!

but every time they use another link code, it overrides the original affiliate cookie and takes the latest affiliate cookie

Yes last cookie wins.
