The same trip (Barcelona → Paris, €72.05) and the same Yuno SDK underneath — three different front-ends, all in Vueling’s brand. Pick how much of the UI Yuno renders.
startSeamlessCheckout()
Minimal single-card. Yuno renders the card form into your element — you keep the button and the brand.
yuno.secureFields()
Premium two-column. PAN / expiry / CVC are PCI iframes dropped into your own field boxes — no PCI scope.
apiClientPayment.generateToken()
Dark, app-style. 100% your own inputs — Yuno only tokenises the card and drives 3DS. Full UI control.
