Introduction to Virtual

The Virtual Payment Solution makes use of Wirecard's hosted payment page. This is a popular solution mainly due to the ease of integration into the solution and the high level of Security that it provides to merchants.

The Virtual Solution also has the ability to be customized to such an extent that your client would feel as though they are on your website while making payment, ensuring peace-of-mind throughout the entire checkout process.

The Virtual solution offers the ability for a merchant to customise the logo, colours and details displayed on the payment page so that the cardholder does not feel that they are leaving the merchants website. The Virtual Payment Page is operating behind TLS (Transport Layer Security) security protocol and all information that is captured on the payment page is encrypted using 128-bit encryption ensuring that your client's credit card details are kept safe.

Virtual Features

• The merchant is not required to implement TLS, therefore saving costs.
• Both the merchants logo and details can be hosted on the payment page.
• CSS Editor allowing full payment page customization.
• Email confirmation can be sent to card holder for successful purchases.
• The Fraud Module can be configured to help reduce fraud.
• Failure and Success Pages can be configured to be displayed by Wirecard.
• Additional detail such as shipping address and purchase items can be displayed on the payment page
• This is a quick and easy method which ensures less programming.
• Basic development skills are required.

Virtual Payment Process

One of the main benefits of utilising the Virtual Solution is the simplicity in which to integrate it into your online website. It requires less development work than other Wirecard Solutions and security measures are already incorporated by Wirecard.

Virtual allows the merchant to utilize the Wirecard payment webpage. This means that your clients will be directed to Wirecard's Payment Page where they will enter their credit card details in order for the transaction to be completed. The payment information which Wirecard requires is posted to Wirecard via a form POST. This POST can be done in any language that supports this method.

Illustration: Virtual Payment Process

Step 1 – Cardholder makes purchase from merchant's website.
Step 2 – Merchant creates form post to Virtual payment page.
Step 3 – Wirecard processes the transaction to the merchant Bank.
Step 4 – The merchant bank processes the transaction and returns a successful or declined message.
Step 5 – Wirecard returns this result and/or error code with error description back to the Merchant
Website address specified in the form POST.
Step 6 – If the functionality is set up (from the Wirecard Web Console) Wirecard will notify the card
holder via email of the transaction details and the merchant via email.

General Requirements for Using Virtual

• Website – You must have a website or shopping cart and have ability to load sample code or shopping cart code to the site.
• Internet Merchant Account – You are required to have an internet merchant account with a bank.
• Internet Connectivity – Internet connectivity is required to post the transaction.
• Internet Service Provider (ISP) – An ISP is required to host your site.
• Wirecard issued Merchant ID and Application ID – Required parameters when sending your form post.

Internet Merchant Account

An Internet Merchant Account is required to accept credit card transactions over the internet. If you have an Internet Merchant Account you need to supply these details to Wirecard before going Live. If you do not have an Internet Merchant Account, Wirecard can assist you with your application to the acquirer (bank).

Note: An Internet Merchant Account is a different type of merchant account than what is used for card present / POS transactions.  You will need to apply for an Internet Merchant Account even if you already accept credit card transactions from your store.

Security – Server Passwords

You need to apply security best business practice to ensure that confidential data and card detail are protected while either being stored in the database or while data is being transmitted. It is suggested that you encrypt key information issued to you by Wirecard. This will be things like your User Access, JWT Token Secret and access tokens.

Note: To reduce fraud or potential incidents it is recommended to encrypt any passwords that give access to your server.

TLS

TLS (Transport Layer Security) is a security protocol that ensures that data being captured on Wirecard's payment page cannot be read by encrypting the data using two encryption keys. The Virtual solution does not require a merchant to implement TLS protocol as this is handled by Wirecard.

Integration

Form Post URL

The form post URL is the Wirecard URL used to submit the form post to.  Wirecard provides the following URL for both Live and Test. 

Test URL : https://staging-apiv2.wirecard.co.za/product/payment/v1/initialisevirtualCopy URL to clipboard

Production URL : https://apiv2.wirecard.co.za/product/payment/v1/initialisevirtualCopy URL to clipboard

Note: Mode has been deprecated and should always be 1. For testing please use the staging url.

Testing

View all ApplicationUIDs

For testing purposes, we have provided a MerchantUID and ApplicationUID's in multiple currencies.

MerchantID: 9ba5008c-08ee-4286-a349-54af91a621b0

JWT Secret: yglTxLCSMm7PEsfaMszAKf2LSRvM2qVW

When going live, these will need to be replaced in your code by using the Wirecard issued MerchantID and ApplicationID. You can retrieve your JWT Secret from the Merchant Portal.

Test Cards

Test Cards are used to perform test authorizations to Wirecard. Test Cards will only work when using the test URL. Test Cards transactions will not go to the acquirer.

Test Card Types

• Visa
• MasterCard
• Amex
• Diner
• Maestro

Note: Test Cards will only work when posting to the test URL.

Test CCV

As additional account security, every credit card comes with a special three or four digit code generally known as a CVV2 or CVV number. Cardholders will be requested to enter this when processing an online payment. An identity thief who has come across credit card information illegally will not have access to the CVV number if they do not have physical access of the card.

JSON Web Token (JWT)

What is JSON Web Token?

"JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed."

You can read more here (https://jwt.io/introduction)

You must implement the JSON Web Token (JWT) in the request to us and validate the response token (_RESPONSE_TOKEN)

We strongly recommend the following validation on the response token:

1. Confirm the signature of the JWT token is valid

2. Confirm that the values in the JWT token match with the values for the order.

3. The values that must get validated are:

   mref (Merchant Reference)

   amount

   auid (Application UID)

   cuid (Merchant UID)

4. Use the result field in the JWT token as your success and failed indicator

Warning: Failure to put the recommended JTW token validations in place could lead to financial losses.

}

JWT(Token field) can be programatically constructed as follows:

php Example using a standalone php library

require_once('jwt.php');

  $SecretKey = 'NFeCMY17FoaDkLe3azMchsNbLOpgkO2Wh58'; //Supplied by Wirecard

  $payloadArray = array();
  $payloadArray['iss'] = $iss; //The identity of the party that issued the JWT. The claim holds a simple string, of which the value is at the discretion of the issuer
  $payloadArray['cuid'] = $MerchantID;
  $payloadArray['auid'] = $ApplicationID;
  $payloadArray['amount'] = $amount;
  $payloadArray['mref'] = $merchantReference;
  $payloadArray['jti'] = base64_encode(random_bytes (32));
  $payloadArray['iat'] = time() - 60;
  $payloadArray['exp'] = time() + 600;

  //$Token will be used to populate the Token form field in the POST to our payment page
  $Token = JWT::encode($payloadArray, $SecretKey);

You can download the above sample code here (Virtual Example with JWT.zip)

You can find more code examples here (https://jwt.io/#libraries-io)

HTML Sample

If you have in‐depth HTML knowledge or web development skills you can create more variables. The below examples could be applied if you have a web application or shopping cart. The Below HTML example shows how your form POST could look when extensive information is getting sent to Wirecard:

The below code can be copied into your code for testing purposes. Please note however, that before going live, you will need to change the details in the above example.

Note: The Virtual solution does not support iframes, if you wish to process payments without the user leaving your website please consider the enterprise solution.
