Send data to Infopath form in SharePoint 2013 List

Hello,

I created a windows 8 app that uses SharePoint as a repository for my data.

I have an infopath form that users would usually enter in via a browser but instead I wanted to build a form within my app and on submit the data would go to the info path form in SharePoint.

The confusion comes in because the form has three fields and it is in a SharePoint list not a library so it has to be more specific when sending the data.

Any help on how to start this would be great, haven't seen much documentation on how to accomplish this.

Thanks!
