r/Affiliate

A company gave me $100 in store credit to buy their products, and I also signed up for their affiliate program. I now have a 10% discount code that people can use, but anyone can get the same 10% discount just by signing up on the brand’s website. I earn commission if people use my code. What is this type of partnership actually called? Is it considered a gifted collaboration, affiliate marketing, UGC, or something else?
