External Checkout - Integration Guide

External Checkout allows partners to replace Nuitée’s built-in payment step with their own checkout experience while continuing to use Nuitée for hotel search, room selection, booking confirmation, and supplier connectivity.

When a guest is ready to pay, Nuitée securely redirects them to your checkout flow using a signed payload. Your platform collects payment and confirms the booking back to Nuitée through a server-to-server callback.

External Checkout supports two integration modes:
