Once you've registered as an affiliate with a shop, you will need to use a customized URL when you refer leads so that your commission can be tracked. To find the referral URLs for your shops, first click the "Referral URLs" option in the navigation on the left. (You may also click here.)

From here, you will find all of your Referral URLs for the shops you have registered with.

When you refer customers to a shop that you're promoting, the customers must use the provided referral URL. If the customer is linked to the shop through a different URL, there will be no way to link that customer's conversion to your referral.
