Response

Start adding a card (admin)

Everything the client needs to mount an embedded card-capture form. The resulting payment method is NOT returned here — it appears once the card rail webhook confirms it (spec §6: never inferred from a client callback).

clientSecret
string
required

The capture-session client secret. The UI passes this to the embedded card form (no redirect) to collect and confirm the card.

publishableKey
string
required

The card rail's publishable key, for mounting the embedded card form client-side. Not secret.
