The Affiliate Program is designed to incentivize merchants to promote the payment gateway to their network. By referring new businesses to the payment gateway, merchants can earn commissions based on the transactions processed through those referrals. This feature not only helps in expanding the user base of the payment gateway but also creates a mutually beneficial relationship between the payment gateway provider and the merchants. The program typically includes tracking mechanisms to monitor referrals and calculate commissions accurately, ensuring transparency and trust in the partnership.
