An Affiliate link is a special product link that contains your unique tracking ID.

When other users click on your link and buy the item, you earn a percentage of the sale (commission) from the store.

Where to get it?

You need to sign up for the store's affiliate program. Once registered, the store will provide you with a tool (a link generator) where you paste a regular product link, and it turns it into your personal affiliate link. You should paste this generated link into the field.
