About
Primer is the unified payments infrastructure platform that enables global merchants and enterprises to orchestrate, automate, and optimize their entire payments stack from a single integration. The platform connects merchants to any payment service provider, fraud tool, or commerce service through a no-code workflow builder and a single unified API — eliminating the need to manage multiple payment integrations independently. Primer's infrastructure supports payment routing, retry logic, 3DS authentication, subscription billing, and real-time analytics across 200+ payment methods and processors. The platform is designed for enterprise e-commerce businesses seeking flexibility and control over their payments stack without ongoing engineering overhead. Customers include GetYourGuide, Conforama, and other global e-commerce merchants.
