I need to change my Stripe integration and switch to paypal integration on my ruby on rails app. I want it to look/feel the same as I currently have. I have set up a demo for you to deconstruct here: http://referralfactory.co/demo
The after the user enters a valid dropbox URL and a valid email the button should become valid. Then the user will be directed through the most painless paypal process as possible. It would be best if they could stay on the same page with a lightbox. The page must be able to catch a callback and be notified if the charge was sucessful. Then It will post to the server via ajax like the current set up.
This should be a fairly straight forward if you have integrated Paypal with Rails and JS before as all of the order fulfillment is done. To be considered for this job your message must start with "Mr. Ref".
There will be additional work with a bitcoin payment provider, coinbase.com, if you deliver top quality work.
Thank you for taking the time to read this through in its entirety.
