Fiserv Payment Gateway - Overview
Adding Payment Acceptance Capabilities to a Website
The easiest way to add payment capabilities to your website is to implement a HTML form that you post to our Payment Gateway URL. This type of integration allows you to let our Payment Gateway manage customer redirections that are required in the checkout process of many payment methods or authentication mechanisms. Our Payment Gateway also gives you the option to use secure hosted pages or an embeddable form which can reduce the burden of compliance with the Data Security Standard of the Payment Card Industry (PCI DSS).
Application Programming Interface (API)
For steps where no direct consumer interaction is required and no sensitive cardholder data is processed, it's best to use our Application Programming Interface (API). Please note that if you plan to collect your customer's card details within your environment and send it to our API, you must ensure that your system components are PCI DSS compliant.
