Integrate PayPal Express Checkout Flow in a project that use GWT-RPC

[Antonino Vitaliti]

Hi! In my GWT-RPC project I've created the page that handles the basket, after I have added the PayPal Button. I have also created a sandbox account, and now I would use the PayPal express checkout, after the billing step I would skip directly on payment with paypal. I don't know how use this PayPal integration wizard in my case; I put on my basket package expresscheckout.java and paypalfunctions taken from the next step and I have changed the API credentials  in paypalfunctions.java as suggested.  please can someone help me give me the step that I have to do in order to make functional the paypal Checkout? I've read API but I'm very confused...Thanks a lot!

Without spending a whole lot of time on it, if you want to use GWT-RPC I think you'd basically copy most of the code from expresscheckout.java into your server-side RPC call so that it's calling paypalfunctions's "CallShortcutExpressCheckout" from paypalfunctions.java directly.

You'll need to handle the session stuff differently somehow though, either passing the amount and token back and forth from the client or storing it on the server some other way.

Good luck!
