Paymentsense is a United Kingdom payment processing company that provides card payment acceptance to small and medium-sized businesses through card machines (PDQ terminals), online payment gateways, and EPOS integrations. Now part of Dojo, its developer-facing surface centers on the Connect platform, a cloud-hosted integration layer that gives each merchant an isolated host so point-of-sale and hospitality software can drive card terminals without touching card data. Paymentsense publishes a genuine public developer portal at docs.connect.paymentsense.cloud with interactive Swagger reference docs and downloadable OpenAPI/Swagger specifications for the Connect REST API (Pay-At-Counter and Pay-At-Table terminal integration, versions v0/v1/v2) and the Connect-E REST API for online/e-commerce card payments, plus a documented WebSockets interface. Authentication is HTTP Basic using a per-merchant API key supplied by Paymentsense. A separate merchant/software-house management portal at developers.paymentsense.com sits behind Google sign-in.
