Nadh,
SNC integration would be the same as you do to a normal integration. The only difference is in a normal integration you have to built your own data types, message types etc.
But for SNC there is a predefined content given by SAP. So you can use them directly. Also they have predefined mappings where you can use them directly if you are using a standard messages. If their is customizations then you may need to change according to your requirements.
Check sap help link in the above reply which may give you an idea. If you have any specific question then post it here, somebody may help you.
