Integrating Prodigi for print on demand orders directly through my website

Hi,

I am currently rebuilding my website and want to set up a shop for print on demand orders. I was hoping to fully integrate Prodigi but don't see that option available. I am trying to figure out how to best integrate this, whether it is using Shopify + the Prodigi app or just a Prodigi account on its own and how to make sure everything is linked correctly. Has anyone has success doing this? It seems like there are a few options and I want to streamline things as much as possible.
