  title: Kalixo Checkout API
  version: '2026-10-01'
  summary: Payment orchestration API for Kalixo partners.
  description: >
    Kalixo Checkout lets partners collect payments from their shoppers through
    one

    provider-neutral API. Kalixo is merchant of record and handles payment

    processing, so partners never integrate a payment provider directly.


    - Amounts are integers in the currency's minor unit (EUR 49.99 = `4999`).

    - Server endpoints use a secret key (`kc_sk_test_...` or `kc_sk_live_...`).

    - Client endpoints are called by `Kalixo.js` with a publishable key and the
      checkout session's `client_secret`.
    - Every `POST` with a secret key requires an `Idempotency-Key` header.
