title: Grails and PayPal (Express Checkout)
body: <p>There are two PayPal plugins for Grails, the <a href="https://github.com/mstine/grails-paypal-plugin" rel="nofollow">first I found is a year old</a> and seems to be in well enough order. The <a href="http://grails.org/Paypal+Plugin" rel="nofollow">second it a bit older and apparently not compatible with 1.1+</a>. </p>
  
  <p>If I decide to not use an existing plugin what is the best way to implement a simple Express Checkout flow for Grails? I'm not entirely sure what goes into working with the PayPal API, and their documents are quite the mess at the moment with the move to X.com.</p>
