Tokenization
Tokenization
Tokenization is requested with command U as additional data attached to a payment, pre-authorization, or card verification flow.
await client.pay({
amountCents: 1000,
tokenization: {
service: "recurring",
contractCode: "1666354841608"
}
});
Supported service values
recurring: merchant-initiated recurring agreement.unscheduledOrOneClick: unscheduled credential-on-file or one-click use.
Acquirer rules still apply
The protocol can carry tokenization data, but the merchant contract, terminal estate, and acquirer configuration decide whether tokenization is accepted.
