Quantum Gateway is a product of CDGcommerce, providing reliable, secure, and developer-friendly payment processing for over 20 years.
Quantum Gateway was created with a straightforward goal: make payment processing reliable, secure, and easy to integrate. While other gateways have come and gone, QGW has been a steady partner for merchants since 2006.
As a CDGcommerce product, we combine enterprise-grade infrastructure with the personal service of a company that knows its merchants by name. Our support team is US-based, available 24/7, and actually understands payments.
We offer five distinct integration methods — from fully transparent server-to-server APIs to simple embeddable forms — so you can choose the approach that fits your technical needs.
Battle-tested infrastructure processing millions of transactions.
Clean APIs, extensive docs, real test accounts, and code samples in every major language.
Virtual terminal, vault, recurring billing, fraud tools, and reporting — all included.
Easy migration with our Auth.Net emulation API.
