The setup for the token generation is as follows:

JavaScript
const tokenizationSpecification = {
  type: 'PAYMENT_GATEWAY',
  parameters: {
    'gateway': 'aciworldwide',
    'gatewayMerchantId': '<your_merchant_id>'
  }
};

You must restrict the application to the following authentication method and card networks:

JavaScript
const allowedCardAuthMethods = ["CRYPTOGRAM_3DS"];
const allowedCardNetworks = ["DISCOVER", "MASTERCARD", "VISA"];
