title: DoReferenceTransaction API for PayPal
body: <p>Does DoReferenceTransaction API work with any PayPal account? I'm trying to implement something similar to the one-click buy option seen in Amazon (not recurring billing). Finance still has to get back to me on the type on account we have (Standard, Pro etc). Does the DoReferenceTransaction API work with all types of paypal accounts? </p>
  
  <p>Also, am a bit confused by the types of accounts PayPal has. On PayPal's site I see only Website Payments Standard and Express Checkout. But I hear a lot of conversation about Payment Pro and Payflow Pro and all that. Not sure which is which.</p>
  
  <p>Any inputs/pointers would be appreciated.</p>
