Zero-Authorization

On this page:

Overview

A merchant may want to perform a zero-authorization card transaction in order to:

  • Store card details for future use – Card schemes often insist that a zero-authorization transaction be sent before allowing card credentials to be stored for future use.
  • Add a card (card registration) – A customer is sometimes required to add a card to their account so that it can be verified and used to charge the customer at a later date. For example, adding a card at the beginning of an evaluation period so it can be verified and charged at the end of the evaluation period.
  • Verify a card – A merchant may want to move a potential customer to the next stage in the sales cycle by asking them to supply their card details. This allows the merchant to verify the existence of a card without charging it as well as testing the customer’s level of commitment to eventually completing the sale.

The zero authentication flows should be performed ONLY if a deposit is NOT performed during the same user session. Any deposit should be performed in a separate session.

A zero-authorization transaction can be performed:

  • With Web SDK
  • With REST API
  • For merchants with a low PCI level
  • For non-3D tokenization

Zero-Auth with Web SDK

  1. Call the /openOrder API call and set amount=0 and transactionType=Auth.
    Example /openOrder API Call 
    {  
    "merchantId":"<your merchantId goes here>",
    "merchantSiteId":"<your merchantSiteId goes here>",
    "clientUniqueId":"<unique transaction ID in merchant's system>",
    "clientRequestId":"<unique request ID in merchant’s system>",
    "currency":"USD",
    "amount":"0",
    "userTokenId": "<a user identifier>",
    "transactionType": "Auth",
    "billingAddress":{
        "email":"john.smith@email.com",
        "country":"US"
    },
    "timeStamp":"<YYYYMMDDHHmmss>",
    "checksum":"<calculated checksum>"
}
    <?php
$safecharge = new \SafeCharge\Api\RestClient([
'environment' => \SafeCharge\Api\Environment::INT,
'merchantId' => '<your merchantId>',
'merchantSiteId' => '<your merchantSiteId>',
'merchantSecretKey' => '<your merchantSecretKey>',
]);

$openOrderRequest = $SafeCharge->getPaymentService()->openOrder([
    'clientUniqueId'    => '<unique transaction ID in merchant's system>',
    'clientRequestId'   => '<unique request ID in merchant’s system>',
    'currency'          => 'USD',
    'amount'            => '0',
    'userTokenId'       => '<a user identifier>',
    'transactionType' => 'Auth',
    'billingAddress' => [
        'country'   => "US",
        "email"     => "john.smith@email.com",
    ],
]);
?>
    public static void main(String[] args) {
// for initialization 
String merchantId = "<your merchantId>";
String merchantSiteId = "<your merchantSiteId>";
String merchantKey = "<your merchantKey>";
safecharge.initialize(merchantId, merchantSiteId, merchantKey, Constants.HashAlgorithm.SHA256);

//for openOrder
String userTokenId = "<a user identifier>";
String clientUniqueId = "<unique transaction ID in merchant's system>";
String clientRequestId = "<unique request ID in merchant’s system>";
String currency = "USD";
String amount = "0";
String transactionType = "Auth";

UserAddress billingAddress = new UserAddress();
billingAddress.setEmail("john.smith@email.com");
billingAddress.setCountry("US");

Safecharge safecharge = new Safecharge();
SafechargeResponse response = safecharge.openOrder(userTokenId, clientRequestId,
clientUniqueId, null, null, null, transactionType, currency, amount,
null, null, null, null, billingAddress, null, null, null,
null, null, null, null, null, null, null);
}
    var safecharge = new Safecharge(
"<your merchantKey>",
"<your merchantId>",
"<your merchantSiteId>",
"<your server host value>",
HashAlgorithmType.SHA256
);
var response = safecharge.OpenOrder(
 "USD",
 "0",
 transactionType: "Auth",
 userTokenId: "<a user identifier>",
 clientUniqueId: "<Transaction ID in your system>",
 clientRequestId: "<unique request ID in merchant’s system>",
 billingAddress: new UserAddress
 {
     Email = "john.smith@email.com",
     Country = "US",
 }
);
    const safecharge = require('safecharge');
safecharge.initiate(<merchantId>, <merchantSiteId>, <merchantSecretKey>, <env>);
safecharge.paymentService.openOrder({
    'clientUniqueId'   : '<unique transaction ID in merchant's system>',
    'clientRequestId'  : '<unique request ID in merchant’s system>',
    'currency'         : 'USD',
    'amount'           : '0'
    'transactionType' : 'Auth',
    'userTokenId' : '230811147',
    'billingAddress': {
        'email': "john.smith@email.com",
        'country': "US"
    },
}, function (err, result) {
    console.log(err, result)
});
  2. Use a createPayment() call to send an authorization-only request.
    Example createPayment() Request 
    sfc.createPayment({
    "sessionToken": "3993eb0c-5f64-4a6c-b16c-485818eb76eb", //received from openOrder API 
    "merchantId": "<your merchantId>", //as assigned by Nuvei
    "merchantSiteId": "<merchantSiteId>", //as assigned by Nuvei
    "clientUniqueId": "<unique transaction ID in merchant's system>", // optional
    "paymentOption": {
      "card": { //this sample clearly shows text cards can also work with Nuvei Fields
        "cardNumber": "5111426646345761",
        "cardHolderName": "John Smith",
        "expirationMonth": "12",
        "expirationYear": "2022",
        "CVV": "217"
      }
    }
  },
  function(res) {
    console.log(res) if (res.cancelled === true) {
      example.querySelector('.token').innerText = 'cancelled';
    }
    else {
      example.querySelector('.token').innerText = res.transactionStatus + ' – Reference: ' + res.transactionId;
    }
    example.classList.add('submitted');
  }
)
  3. Perform a full 3D-Secure challenge (see 3D-Secure Guide) to comply with the “strong authentication validation” requirement set by card schemes for each zero-authorization request.

Zero-Auth with REST API

  1. Call the /getSessionToken method.
    Example /getSessionToken Request 
    {
    "merchantId": "<your merchantId>",
    "merchantSiteId": "<your merchantSiteId>",
    "clientRequestId": "<unique request ID in merchant’s system>",
    "timeStamp": "<YYYYMMDDHHmmss>",
    "checksum": "<calculated checksum>"
}
    $safecharge = new SafeChargeApiRestClient([
'environment' => SafeChargeApiEnvironment::INT,
'merchantId' => '<your merchantId>',
'merchantSiteId' => '<your merchantSiteId>',
'merchantSecretKey' => '<your merchantSecretKey>',
]);
    public class Main {
    public static void main(String[] args) {
        String merchantId = "<your merchantId>";
        String merchantSiteId = "<your merchantSiteId>";
        String merchantKey = "<your merchantKey>";

            safecharge.initialize(merchantId, merchantSiteId, merchantKey, Constants.HashAlgorithm.SHA256);
    }
}
    var safecharge = new Safecharge(
"<your merchantKey>",
"<your merchantId>",
"<your merchantSiteId>",
"<your server host value>",
HashAlgorithmType.SHA256
);
    const safecharge = require('safecharge');
safecharge.initiate(<merchantId>, <merchantSiteId>, <merchantSecretKey>, <env>);
  2. Initialize the payment in the Nuvei system by sending an /initPayment request and setting amount=0 and transactionType=Auth.
    Example /initPayment Request 
    {
    "sessionToken": "<sessionToken from getSessionToken>",
    "merchantId": "<your merchantId>",
    "merchantSiteId": "<your merchantSiteId>",
    "userTokenId": "<a user identifier>",
    "clientRequestId": "<unique request ID in merchant’s system>",
    "clientUniqueId": "<unique transaction ID in merchant's system>",
    "currency": "USD",
    "amount": "0",
    "transactionType": "Auth",
    "paymentOption": {
        "card": {
            "cardNumber": "4000027891380961",
            "cardHolderName": "CL-BRW1",
            "expirationMonth": "12",
            "expirationYear": "2022",
            "CVV": "217",
            "threeD": {
                "methodNotificationUrl": "<methodNotificationURL>"
            }
        }
    },
    "deviceDetails": {
        "ipAddress": "127.0.0.1"
    }
}
    <?php
//initPayment
$initPaymentResponse = $safeCharge->getPaymentService()->initPayment([
    'currency'       => 'USD',
    'amount'         => '0',
    'userTokenId'    => '<a user identifier>',
    'transactionType' => 'Auth',
    'clientRequestId' => '<unique request ID in merchant’s system>',
    'paymentOption'  => [
        'card' => [

            'expirationMonth' => '12',
            'expirationYear'  => '2022',
            'CVV'             => '217',
            'threeD' =>[
                'methodNotificationUrl'=>'<methodNotificationURL>',
            ]
        ]
    ],
    'deviceDetails'     => [
        "ipAddress"  => "127.0.0.1"
    ],
]);
?>
    {
    // Parameters needed for initPayment call
    String userTokenId = "<a user identifier>";
    String clientUniqueId = "<unique transaction ID in merchant's system>";
    String clientRequestId = "<unique request ID in merchant’s system>";
    String currency = "USD";
    String amount = "0";
    String transactionType = "Auth";

    DeviceDetails deviceDetails = new DeviceDetails();
    deviceDetails.setIpAddress("127.0.0.1");

    InitPaymentThreeD threeD = new InitPaymentThreeD();
    threeD.setMethodNotificationUrl("<methodNotificationURL>");

    InitPaymentCard card = new InitPaymentCard();
    card.setCardNumber("4000027891380961");
    card.setCardHolderName("CL-BRW1");
    card.setCVV("217");
    card.setExpirationMonth("12");
    card.setExpirationYear("2022");
    card.setThreeD(threeD);

    InitPaymentOption initPaymentOption = new InitPaymentOption();
    initPaymentOption.setCard(card);

    Safecharge safecharge = new Safecharge();
    SafechargeResponse response = safecharge.initPayment(userTokenId, clientUniqueId, clientRequestId, currency, amount, transactionType, deviceDetails, initPaymentOption, null, null, null);
}
    var response = safecharge.InitPayment(
    "USD",
    "0",
    new InitPaymentOption
    {
        Card = new InitPaymentCard
        {
            CardNumber = "4000027891380961",
            CardHolderName = "CL-BRW1",
            ExpirationMonth = "12",
            ExpirationYear = "22",
            CVV = "217",
            ThreeD = new InitPaymentThreeD
            {
                MethodNotificationUrl = "<MethodNotificationUrl>",
            }
        }
    },
    transactionType: "Auth",
    userTokenId: "<a user identifier>",
    orderId: "33704071",
    clientUniqueId: "<unique transaction ID in merchant's system>",
    clientRequestId: "<<unique request ID in merchant’s system>",
    deviceDetails: new DeviceDetails { IpAddress = "127.0.0.1" });
    safecharge.paymentService.initPayment({
    userTokenId            : "<a user identifier>",
    clientRequestId        : "<unique request ID in merchant’s system>",
    clientUniqueId         : "<unique transaction ID in merchant's system>",
    amount                 : "0",
    currency               : "USD",
    transactionType        : "Auth",
    paymentOption  : {
        card: {
            cardNumber      : "4000027891380961",

    },
}, function (initPErr, initPRes, reqData) {
    console.log(initPErr, initPRes);
});
  3. Perform a full 3D-Secure challenge (see 3D-Secure Guide) using a /payment API call to send an authorization-only request. Make sure to set amount=0 and transactionType=Auth.
    Example /payment API Request (for 3D-Secure v2)

Zero-Auth for Merchants with a Low PCI Level

This flow is a combination of using REST API and Web SDK and is used for tokenization by merchants without a sufficient PCI level.

  1. Call the /getSessionToken method.
    Example /getSessionToken Request 
    {
    "merchantId": "<your merchantId>",
    "merchantSiteId": "<your merchantSiteId>",
    "clientRequestId": "<unique request ID in merchant’s system>",
    "timeStamp": "<YYYYMMDDHHmmss>",
    "checksum": "<calculated checksum>"
}
    $safecharge = new SafeChargeApiRestClient([
'environment' => SafeChargeApiEnvironment::INT,
'merchantId' => '<your merchantId>',
'merchantSiteId' => '<your merchantSiteId>',
'merchantSecretKey' => '<your merchantSecretKey>',
]);
    public class Main {
    public static void main(String[] args) {
        String merchantId = "<your merchantId>";
        String merchantSiteId = "<your merchantSiteId>";
        String merchantKey = "<your merchantKey>";

            safecharge.initialize(merchantId, merchantSiteId, merchantKey, Constants.HashAlgorithm.SHA256);
    }
}
    var safecharge = new Safecharge(
"<your merchantKey>",
"<your merchantId>",
"<your merchantSiteId>",
"<your server host value>",
HashAlgorithmType.SHA256
);
    const safecharge = require('safecharge');
safecharge.initiate(<merchantId>, <merchantSiteId>, <merchantSecretKey>, <env>);
  2. Call the getToken() Web SDK method.
    Example getToken() Request 
    sfc.getToken(sfcCard).then(function(result) {

        if (result.status === 'SUCCESS') {
             console.log(result.paymentOption) //pass the paymentOption to the payment API call
        } else {
            // handle error.

        }
    });
  3. Initialize the payment in the Nuvei system by sending an /initPayment REST API method and setting amount=0 and transactionType=Auth.
    Be sure to include the ccTempToken retrieved from the Web SDK getToken response.
    Example /initPayment Request 
    {
    "sessionToken": "<sessionToken from getSessionToken>",
    "merchantId": "<your merchantId>",
    "merchantSiteId": "<your merchantSiteId>",
    "userTokenId": "<a user identifier>",
    "clientRequestId": "<unique request ID in merchant’s system>",
    "clientUniqueId": "<unique transaction ID in merchant's system>",
    "currency": "USD",
    "amount": "0",
    "transactionType": "Auth",
    "paymentOption": {
        "ccTempToken":"<as returned by getToken method>",
        "card": {
            "cardHolderName": "CL-BRW1",
            "threeD": {
                "methodNotificationUrl": "<methodNotificationURL>"
            }
        }
    },
    "deviceDetails": {
        "ipAddress": "127.0.0.1"
    }
}
    <?php
//initPayment
$initPaymentResponse = $safeCharge->getPaymentService()->initPayment([
    'currency'       => 'USD',
    'amount'         => '0',
    'userTokenId'    => '<a user identifier>',
    'transactionType' => 'Auth',
    'clientRequestId' => '<unique request ID in merchant’s system>',
    'paymentOption'  => [

            ]
        ]
    ],
    'deviceDetails'     => [
        "ipAddress"  => "127.0.0.1"
    ],
]);
?>
    {
    // Parameters needed for initPayment call
    String userTokenId = "<a user identifier>";
    String clientUniqueId = "<unique transaction ID in merchant's system>";
    String clientRequestId = "<unique request ID in merchant’s system>";
    String currency = "USD";
    String amount = "0";
    String transactionType = "Auth";

    DeviceDetails deviceDetails = new DeviceDetails();
    deviceDetails.setIpAddress("127.0.0.1");

    InitPaymentThreeD threeD = new InitPaymentThreeD();
    threeD.setMethodNotificationUrl("<methodNotificationURL>");

    InitPaymentCard card = new InitPaymentCard();
    card.setThreeD(threeD);

    InitPaymentOption initPaymentOption = new InitPaymentOption();
    initPaymentOption.setCard(card);

    Safecharge safecharge = new Safecharge();
    SafechargeResponse response = safecharge.initPayment(userTokenId, clientUniqueId, clientRequestId, currency, amount, transactionType, deviceDetails, initPaymentOption, null, null, null);
}
    var response = safecharge.InitPayment(
    "USD",
    "0",
    new InitPaymentOption
    {
        Card = new InitPaymentCard
        {
            ThreeD = new InitPaymentThreeD
            {
                MethodNotificationUrl = "<MethodNotificationUrl>",
            }
        }
    },
    transactionType: "Auth",
    userTokenId: "<a user identifier>",
    orderId: "33704071",
    clientUniqueId: "<unique transaction ID in merchant's system>",
    clientRequestId: "<<unique request ID in merchant’s system>",
    deviceDetails: new DeviceDetails { IpAddress = "127.0.0.1" });
    safecharge.paymentService.initPayment({
    userTokenId            : "<a user identifier>",
    clientRequestId        : "<unique request ID in merchant’s system>",
    clientUniqueId         : "<unique transaction ID in merchant's system>",
    amount                 : "0",
    currency               : "USD",
    transactionType        : "Auth",
    paymentOption  : {
        ccTempToken : "<as returned by getToken method>",
        card: {
            threeD :{
                methodNotificationUrl : "<methodNotificationUrl>",
            }
        }
    },
    deviceDetails  : {
        ipAddress  : "127.0.0.1"
    },
}, function (initPErr, initPRes, reqData) {
    console.log(initPErr, initPRes);
});
  4. Perform a full 3D-Secure challenge (see 3D-Secure Guide) using a /payment API call to send an authorization-only request. Make sure to set amount=0 and transactionType=Auth.
    Example /payment Request (for 3D-Secure v2) 
    {
    "sessionToken":"<sessionToken from getSessionToken>",
    "merchantId":"<your merchantId>",
    "merchantSiteId":"<your merchantSiteId>",
