against allow authorize contact error gateway market merchant mode net payment process processed processor received returned run setup system transaction transactions type

I just setup a new merchant gateway and received the following error when trying to process my first transaction via Authorize.net:

3

87
Transactions of this market type cannot be processed on this system.

Anyone know what it means? Also, it seems that e-Junkie can't run in Test Mode against Authorize.net - is that true?

The error is being returned by Authorize.Net and you will need to contact them about this.

Yes, we don't allow test mode for any payment processor.
