This question is here. What I have done I read from Paypal site that IPN can be used to: Update their inventory. Email a purchase confirmation. Trigger order fulfillment. Enable download of digital media. Update their customer list. Email a shipping notification. Issue a refund. Update accounting-related information. And here is a way to configure IPN for Prestashop. Also I saw this file(3rd link) in a Prestashop Github fork. There is no IPN in main repository, 4th link. I read that Prestashop is intented to be used with Express Checkout. My questions Should I use Prestashop with IPN? Where can I read how Express Checkout works with Prestashop? Questions in case I should use IPN: How to do the most basic setup of IPN within Prestashop? What will this most basic setup do? I can share only 2 links , 3rd and 4th link will not be here.
