Keep in mind that your customer should know that you, as the affiliate, will be receiving some commission from the purchase. 

As per the Federal Trade Commission, an affiliate marketer should explicitly reveal their relationship with the retailer. This will allow consumers to determine the amount of importance to place on the endorsement of your business.

A statement like “The products I’m going to use in this video were given to me by Company X” will give your viewers all the details they require to take an educated choice regarding whether or not to purchase the product from an affiliate.
