New Post: How to implement worldpay payment gateway

I think you are taking my Step 1 wrong whenever I install some extensions like in case of a NB store NEvoweb.DNN.modules.nbstore.gatewaypaypal dll file automatically comes under the website Bin folder. Similarly how can I get the worldpay dll file so that whenever user click on the Go to checkout it moves to the worldypay website for payment. For integrating this the things that comes in mind is that we need some Worldpay API Or something similarly.
