A link will usually have some sort of advertising surrounding it, something to lead the consumer to click on the link. So it is probably a referral. Alternatively, the affiliate may be verbally telling the consumers to go to the link and provide the information to apply. This would also likely be a referral. As such, I would say the disclosure and the other requirements of 1024.15 are in play for you.
