Addind PayPal Pay Later Messaging and Buttons to Shopify Products Pages, Cart, and Checkout?

[TorresHovsco]

Hi Everyone,

I am trying to add PayPal Pay Later messaging on my Shopify store.

Has anyone who does PageFly integrated this into their shopify store?

I am trying to present this messaging from Product > Cart > Checkout.

Also, if you did this by customizing the theme, please let me know as well.

I have tried finding the correct cart and checkout file in my theme but I cannot find them in theme sections.
