Hi,

We’re using a 3rd party processor called Moneris, They have their own 3D secure service that is activated and functional. The problem is that we cannot get it working with Shopify unless we add some custom code to the shopping cart to “call” the service. We have the documentation from Moneris but figuring out what part we need to implement into the shopify cart system is a little overwhelming.

Can someone point me in the right direction to get help our situation?

Thank you
