What is the ruling on dealing with the company "ClickBank" as a marketer for its products in exchange for a commission that reaches up to 75%?

It is permissible to market and sell products for a specified commission or a percentage of the price. This falls under the category of brokerage (samsara) and a contract of recompense (ja'ala), provided that the product is permissible and the commission is known. There is no harm in the commission being a percentage of the price, which is the preponderant opinion. It must be noted that it is forbidden to market products if the company requires the marketer to purchase the product or imposes subscription fees, as this involves gambling. If the product is gold or currency, immediate exchange (taqabud) is required. Cooperation with companies that deceive buyers and sell products for many times their real value should be avoided.
