title: How to debug failed transactions with PayPal Express Checkout?
body: <p>We're using PayPal Express Checkout (implemented in Ruby, Active Merchant gem)</p>
  
  <p>A few transactions failed recently, while majority work fine.</p>
  
  <p>I have looked at our log file and identified the user who had failed transactions.</p>
  
  <p>I have the transaction token, PayerID, user's email address, correlation ID.</p>
  
  <p>I have contacted PayPal technical support about this and provided them with the above details.</p>
  
  <p>But I wonder if it's possible to get more information about these failed transactions myself.
  Does the Ruby gem Active Merchant provide an easy way to get it from PayPal?</p>
  
  <p>Thanks</p>
