I'm trying to get my API going and it works great for successess, but I can't test a decline/failure situation because I can't get anything to fail. Testing says billing zip code = 46282 should trigger a decline, but neither an API call (using Java SDK) nor the virtual terminal in test-mode/sandbox do this.
(ALso, should the txn id be 0? That seems suspicious, even for test mode.)
What am I doing wrong?
