Prerequisites for Creating an Alias

• The merchant ID has to support the Alias feature.
• The payment method has to support the Alias feature.

How to Create an Alias

There are two ways to create an Alias:

• As a result of a payment transaction.
• As a result of a dedicated registration.

There exist some exceptions, where a token can only be created with a dedicated registration. This is the case for Twint when using our mobile SDK integration.

Card Registration after a successful payment transaction

Parameter to return an Alias after a transaction

Simply add the parameter useAlias=yes in your request to return a token of the card used during the purchase.

Merchants can send the parameter useAlias=yes within their requests to create a token. After successful authorization, the response will contain the alias in the return parameter aliasCC. You can save this value together with the expiry date to process recurring payments.

Datatrans.startPayment({
          form: "#lightbox-form",
          params: {
            "merchantId": merchantId,
            "amount": amount,
            "currency": currency,
            "refno": refno,
            "sign": sign,
            "successUrl":successUrl,
            "errorUrl":errorUrl,
            "cancelUrl":cancelUrl,
            "useAlias":"yes"
          }      
        });

Receive an Alias on customers choice

Apply parameter uppRememberMe=true

When using this parameter the consumer will see a "remember payment credentials" checkbox on the payment page.

If the consumer checks the checkbox, the parameter useAlias=true will be added automatically to the request. Use uppRememberMe=checked if the checkbox should be checked as a default. Once again, the response will contain the aliasCC parameter.

Datatrans.startPayment({
         form: "#lightbox-mode",
         params: {
            "merchantId": merchantId,
            "amount": amount,
            "currency": currency,
            "refno": refno,
            "sign": sign,
            "successUrl":successUrl,
            "errorUrl":errorUrl,
            "cancelUrl":cancelUrl,
            "uppRememberMe":"checked"
          }      
        });

By doing a Registration only

This approach should be used if the merchant only wants to register a consumer payment credentials without doing an actual payment. If the merchant sends parameter amount=0, Datatrans validates the card number accordingly.

Datatrans.startPayment({
          form: "#lightbox-mode3",
          params: {
            "merchantId": merchantId,
            "amount": 0,
            "currency": currency,
            "refno": refno,
            "sign": sign,
            "successUrl":successUrl,
            "errorUrl":errorUrl,
            "cancelUrl":cancelUrl
          }      
        });

Alias Creation in iOS SDK

iOS app developers can refer to chapter 3, which describes how to set several options within the payment controller DTPaymentController. You will need to define the following option to request an alias creation:
paymentController.paymentOptions.returnsAlias = YES;

Alias Creation in Android SDK

Android app developers can refer to the classes AliasPaymentMethod* to create an alias after a successful transaction. You will also need to set the method setRecurringPayment to true within the PaymentOptions class.
