Payment21® can be integrated easily and quickly via our API technology or through a simple payment button.

Over the past decade, Payment21® has managed several Internet websites selling various products and services to consumers. We have gained extensive expertise in the area of e-commerce from being an active merchant ourselves. From this humble beginning, our company has put a great deal of emphasis on system design and state-of-the-art application development tailored to the needs of vendors and their customers. With our understanding of the requirements of online shoppers and e-businesses our knowledge of Internet payments evolved into a processing business that focuses on speedy integration and easy-to-use applications.

We have developed an internal knowledgebase of our own, which enables multiple development projects across borders and leverages developers all over the world. Payment21® can be integrated easily and quickly via our API technology or through a simple payment button. Technical specifications are available in the member area.
