Online Payments – New Solution

Your Online Payments solution is evolving

As part of our ongoing effort to broaden our service offering and support a wider range of integration needs, we are introducing a new online payment solution based on the new Front-End APIs developed by AltaPay – a Market Pay company.

This new solution expands our existing offering and provides merchants with additional flexibility, including access to new payment methods.

To support your implementation, you will find the API documentation below. It includes all endpoints, workflows, and technical details required for a smooth integration.

If you have any questions or need assistance, your Customer Success Manager or Implementation Manager remains at your disposal.

Access the complete documentation here: Home - AltaPay Documentation.
