A Common Hop Link URL for your program should look like this, where XXXXXX is the affiliate's account ID in our system:
https://www.e-junkie.com/ecom/gb.php?cl=291115&c=ib&aff=XXXXXX
A product-specific hop link URL is a bit longer, where YYYYYY would be the product's item ID in our system:
https://www.e-junkie.com/ecom/gb.php?ii=YYYYYY&cl=291115&c=ib&aff=XXXXXX
An invalid link would not redirect to your landing page, so the fact that it redirects successfully should confirm the link is valid. You could also clear your browser cookies (or at least delete any cookies for "e-junkie.com"), then click the link, then search your cookies for "e-junkie.com" and see if you have one named "ej_aff_id291115", which would be the referral cookie we'd set in your browser when you clicked the link.
We do not track affiliate link click-thru stats; we only track actual sales resulting from the affiliate's referral, so if the affiliate sees a referral for your program in their Affiliate Admin, that indicates they referred an actual sale. They may be contacting you about it if they are not aware that commissions are typically paid out as a monthly lump sum, rather than being paid instantly as soon as the referred sale occurs. You are responsible for paying out commission earnings to your own affiliates.
