Squarespace currently only supports Stripe as a payment platform. I am looking for a way to fully integrate Paypal as the go-to way to pay (one of the reasons for this is that Stripe’s checkout page is currently in english and that is a complete no-go for our client) with full inventory sync (Squarespace with Paypal), tracking payments in Squarespace(!), etc. — I basically want to reproduce the full e-commerce process behind Squarespace, only not via Stripe, but via Paypal. Whenever I checkout on Squarespace, the whole cart should be sent to Paypal, processed there, the customer pays, is sent back to Squarespace and Squarespace should be aware of the changes/purchase/payment and update the inventory.
Is there a way to achieve this? I have googled extensively and am aware of threads like http://answers.squarespace.com/questions/16845/is-there-a-way-to-integrate-paypal-with-squarespace, this is just simply not enough + opens a ton of new issues (a custom Paypal button is needed whenever a new product is added to Squarespace’s inventory, for example).
