title: Negative testing on paypal sandbox no more available?
body: <p>Before 2 weeks ago we were able to simulate negative testing but actually we can't test error condition (pending, error) in PayPal sandbox, the AdaptivePayment API response give always COMPLETED.</p>
  
  <p>We followed this <a href="https://www.x.com/developers/paypal/documentation-tools/ug_sandbox#errors" rel="noreferrer">guide</a> to set correctly our sandbox account, There are some problems with the new Developer environment.</p>
  
  <p>Can someone tell some tips for testing negative conditions?</p>
  
  <p>Advance Thanks</p>
