First API

First API is a specialized Application Programming Interface (API) technology developed by First Data, now part of Fiserv. This technology is designed to facilitate seamless integration into the First Data Global Gateway. An API, in general, serves as a set of rules and protocols for building and interacting with software applications, enabling different software systems to communicate and share data efficiently.

The First API specifically aims to streamline the process of connecting various business systems to First Data's comprehensive payment processing solutions. By using First API, developers and clients can integrate their systems with the First Data Global Gateway more quickly and with fewer resources than would otherwise be required. This integration enables businesses to process online payments, manage transactions, and leverage advanced security measures to protect consumer data.

The significance of First API lies in its ability to reduce complexity and expedite the deployment of payment gateways, thereby assisting businesses in enhancing their operational efficiencies and reducing time to market for new applications. It supports a range of functions from simple payment processing to complex financial transactions, making it a crucial tool for merchants, financial institutions, and software developers looking to optimize their payment systems.
