Trust Payments is a London-headquartered payment gateway and processor (formerly Secure Trading / SecureTrading) operating across the United Kingdom, Europe, and the United States. It offers online, in-store point-of-sale, unattended, and mobile card acceptance, acquiring, alternative and local payment methods, tokenisation, recurring billing, payouts, and 3-D Secure authentication through its TRU Connect gateway. The developer surface centres on the Secure Trading Payment Platform (STPP) - a server-to-server JSON Webservices API for processing (AUTH, ACCOUNTCHECK, REFUND, SUBSCRIPTION, TRANSACTIONUPDATE, and TRANSACTIONQUERY), a JWT-authenticated client-side JavaScript Library for PCI-reduced hosted card fields, and mobile SDKs, all documented as reference articles in the Trust Payments help centre with Python, PHP, ReactJS, and Swift libraries published under the SecureTrading GitHub organisation. Trust Payments does not publish a downloadable OpenAPI/Swagger definition; production Webservices access requires PCI certification, account approval, and credential (key) exchange, so the surface is documentation-and-SDK driven rather than open self-serve.
