Why does my Authorize.Net test account fail using the sample app they provide?

开发者_运维知识库I just signed up for a Authorize.Net test account, and then I downloaded the SDK, installed it into my Tomcat server, and configured the helper.jsp with my test account information, but when I submit the "coffee shopping cart" example they give, it gives me an error that is really vague and I can't figure it out. Any ideas on how I can debug this?

We're sorry, but we can't process your order at this time due to the following error:

Transactions of this market type cannot be processed on this system. 
response code 3 
response reason code 87 

The response code documentation is here: http://www.authorize.net/support/merchant/Transaction_Response/Response_Reason_Codes_and_Response_Reason_Text.htm

Sounds like you got a retail test account and not an ecommerce test account. Either get a new test account for ecommerce or see if you can get Authnet to change the account type for your current test account.
