The customer's redirect to the online store page

Once the payment is processed by the Payment gateway, the customer is redirected to the online store page. The URL address the customer is returned to is specified during register.do / registerPreAuth.do API call:

• The customer returns to returnUrl (which must be passed during the order registration) in case of successful payment.
• The customer returns to failUrl in case of unsuccessful payment.

Finally, the redirect URL looks like as follows:

https://mybestmerchantreturnurl.com?orderId=98839115-2ce0-7066-99b7-ae7300d72620&lang=en

where orderId and lang paramaters values are automatically affixed to returnUrl by the Payment gateway.

Moreover, there are two variants this affix may be presented in the redirect URL:

• ?orderId=xxx&lang=xx
• &orderId=xxx&lang=xx

where:

• orderId value stands for mdOrder value and has string format;
• lang value stands for language value and has string format.
