  title: Yoco Online Payments Checkout Refunds API
  version: '2026-07-12'
  description: 'Hand-authored OpenAPI for Yoco''s online payments platform, grounded in the public Yoco developer hub (developer.yoco.com). Two surfaces are covered: the Checkout API on https://payments.yoco.com/api (secret-key Bearer auth) for creating hosted checkouts, issuing refunds, and managing webhook endpoints; and the versioned Yoco API on https://api.yoco.com/v1 (JWT Bearer auth with scopes) for reading payments, refunds, and payment links. Operations marked `x-status: modeled` were inferred from the resource design and referenced-but-not-fully-rendered doc pages and should be reconciled against the live docs. All others were confirmed against live reference pages. This document was not fetched from an upstream Yoco OpenAPI file.'
