Unified Multi-Project PG Router Architecture: Routing Toss Payments & Stripe Across Domains with UWS Payments

For engineering teams and SaaS builders managing multiple products and domains, integrating payment gateways like Toss Payments (Single Card, Recurring Billing Key, Global PayPal USD) and Stripe repeatedly across every repository creates massive maintenance overhead and fragmented transaction logs. UWS Payments solves this challenge by acting as a Unified Multi-Project PG Router & Payment Gateway API. By registering your Toss Payments and Stripe credentials once in the central configuration, you can issue service-bound and domain-bound API keys (uws_pay_...) in seconds. Any external web app or microservice can trigger a hosted checkout session via a single POST /api/v1/payments/request call, execute direct server-to-server payment confirmations, or process instant refunds via POST /api/v1/payments/cancel. Every transaction is automatically tagged with its originating Service Name and Domain in the unified payment ledger. Furthermore, with a built-in Model Context Protocol (MCP) SSE server, AI coding assistants like Claude Desktop, Cursor, and Windsurf can autonomously generate checkout links, inspect order statuses, and manage refunds.
