Digital commerce payments are electronic payments, often made with real-time authorization, that are used to support digital commerce transactions. Digital commerce payment vendors combine a payment gateway, payment processing, acquiring services, payment security and fraud detection. Payment gateways initiate payments at the request of merchants and return the responses to those merchants. They offer preexisting connections and certified integrations with key payment acquirers and processors, and many have integrations with other providers in the greater digital commerce ecosystem. All digital commerce payment vendors offer a software as a service (SaaS) payment gateway at a minimum. Many are full-stack providers that include processing and acquiring capabilities, alternative payment methods, fraud detection, payment data tokenization, and other related or ancillary services.
