Question

for example I want to create a web, sell things but they need afíliate código

Answer 1

Beware of scams, as many of those so called "affiliate" programs turn out to be. There's no generator - you need to sign up with each company you want to be an affiliate with individually. Once you are accepted by that company into the program, you can then access your personalized affiliate code from within a dashboard they provide. If this does not answer your question, then please clarify further exactly what you mean.

Answer 2

A really appreciate people like you want to help all of them, just I am learning. Actually I want to know how the website or the programing make the afíliate links
