Generate Card Token

Generates a short-lived token for securely displaying full card details (PAN/CVV) to the cardholder, e.g. in a hosted card-details view.

Path: cardId (string, required). No body.

Returns a short-lived provider token in data.token for use with the card provider’s secure card-details display. Error messages from this endpoint are prefixed with Sudo API Error: (sometimes twice, for provider HTTP errors).

All errors from this folder use { "status": "error", "message": "..." } and are returned as HTTP 400 (including “Card not found” — there is no 404). Success bodies use status: "success" (not success: true like the VTU endpoints).
