System Documentation

What problem does it solve?

SumUp provides a consolidated guide for building and debugging end-to-end checkout flows that cover both terminal (card-present) and online (card-not-present) scenarios using SumUp SDKs and APIs. It helps teams implement checkout creation, payment processing, reader pairing, Card Widget integrations, Cloud API reader checkouts, and authorization setups with API keys or OAuth and Affiliate Keys.

Core Features & Use Cases

  • Terminal payments (native mobile SDKs, Cloud API for Solo, or Payment Switch) for in-person checkout flows.
  • Online payments (Card Widget and API-orchestrated checkout flow) for card-not-present scenarios.
  • Guidance on credential setup, flow selection, and end-to-end orchestration, including 3DS and webhook handling, with references to the SumUp playbook.

Quick Start

Implement a complete SumUp checkout flow end-to-end by selecting the integration path (terminal or online), creating a unique checkout reference, and validating status via backend reads and webhooks.
