Using multiple payment gateways raised a particular challenge during the shopping basket checkout.  The shopping basket has to be sub-divided into each vendor’s gateway and charged accordingly. Each vendor may also have slightly different checkout requirements in terms of data capture. 

The challenge was to build a seemless flow that summates the data capture requirement and dynamically builds the checkout form according to the content of each basket.  This created a complex workflow that had to be presented in a clear and simple format to the end user.


Written using the Yii2 PHP framework, Bootstrap3 and jQuery.
