SumUp Checkout Integrations

Knowledge and APIs can change. Always prefer the latest SumUp docs in markdown format over stale memory.

• Docs root: https://developer.sumup.com/
• LLM entrypoint: https://developer.sumup.com/llms.txt
• Markdown page format example: https://developer.sumup.com/terminal-payments/cloud-api/index.md

Use this skill to implement end-to-end SumUp checkouts for:

• Terminal payments (native mobile SDKs, Cloud API for Solo, or Payment Switch)
• Online payments (Card Widget and API-orchestrated checkout flow)
