I want to test an unauthorized transaction&nbsp;so I can check various the response&nbsp;reason codes, but I can't get it to fail using the bogus credit card numbers.&nbsp;How do I get it to fail or is the only way using a real credit card number, which I don't know that I should do?</P> Mon, 24 Nov 2014 14:00:55 GMT https://community.developer.cybersource.com/t5/Integration-and-Testing/How-do-you-test-invalid-unauthorized-transactions-using-the/m-p/48965#M24589 JeffSGA007 2014-11-24T14:00:55Z https://community.developer.cybersource.com/t5/Integration-and-Testing/How-do-you-test-invalid-unauthorized-transactions-using-the/m-p/48966#M24590 <P>Use the <A target="_self" href="/t5/forums/replypage/board-id/Integration01/message-id/Sandbox Account Error Generation Guide">http://developer.authorize.net/tools/errorgenerationguide/</A></P> Mon, 24 Nov 2014 14:14:11 GMT https://community.developer.cybersource.com/t5/Integration-and-Testing/How-do-you-test-invalid-unauthorized-transactions-using-the/m-p/48966#M24590 RaynorC1emen7 2014-11-24T14:14:11Z
