A payment gateway handles the authorization and processing of payments between the merchant and the financial institutions. It ensures secure, efficient transactions, integrating directly with systems to facilitate online or in-person sales.
Selecting a payment gateway is critical to ensuring seamless and secure payment processing. For developers and tech-savvy businesses, this means looking for one that aligns with your technical requirements, offers strong API capabilities, and provides robust security measures to protect against fraud.
