title: Google Sandbox Checkout Credit Card Failure Test cases
body: <p>I have integrated Google Checkout to my portal &amp; testing against sandbox using Server 2 Server Checkout using version 2.0. All successful credit card test cases are passing, however credit card test failure cases documented in <a href="https://developers.google.com/checkout/developer/Google_Checkout_HTML_API_Credit_Card_Test_Cases#test_case_failed_authorization" rel="nofollow">https://developers.google.com/checkout/developer/Google_Checkout_HTML_API_Credit_Card_Test_Cases#test_case_failed_authorization</a> are failing. </p>
  
  <p>For Eg: if use AVS No Match MasterCard: 5106447623213738 as said in the URL, i expect Google Servers to reply with PAYMENT_DECLINED or authorization failed, but the callback is success &amp; card is shown as charged. I tried other credit cards too in box all those cards are shown charged. </p>
  
  <p>Note: This testing in done in google checkout sandbox (http://sandbox.google.com/checkout) &amp; haven't gone live yet, but would like to test credit card failure test cases. I did lot of searching around to test failure cases but could not get around. Can someone tell me how to do ?</p>
  
  <p>thanks</p>
