title: Is it possible to do credit card payments from a heroku server using activemerchant?
body: <p>I'm building an app that needs to accept credit card payments with something like <a href="http://github.com/Shopify/active_merchant" rel="noreferrer">active merchant</a>. In terms of security, is it possible for it to live on <a href="http://heroku.com/" rel="noreferrer">heroku</a> and use <a href="http://www.authorize.net/" rel="noreferrer">authorize.net</a> (or similar) as the payment gateway?</p>
  
  <p>What if it needs to store the credit card numbers?</p>
  
  <p><strong>Edit</strong></p>
  
  <p>Would not be forwarding users to authorize.net.</p>
