Any and all card numbers declined with response code #3 in sandbox

Hello,

 

I've written a service to integrate with Authorize's API.  We are testing using a sandbox account and it is set to live transactions.  No matter what credit card number we've tried we get a decline with code #3 and responsereasoncode of #123.  Even actual card numbers are throwing a #3 declination.  Does anyone have any ideas what could be happening?  I've got to go live with this service by Thursday.

 

Thanks!

Mike

Hello @mikegar

 

Response Code 123 suggest you're using our sandbox login id and password instead of an API Login and Transaction key for authentication.

Hi Richard,

 

Thanks for the prompt response!  You're right, I am using my sandbox login.  Do I want to use my production login and trankey against the test URL?

 

Thanks!

Mike

 

I used my login and transaction key and I'm still getting an error #3 but the reasoncode is now 13.

Sorted my issue out by using the proper login credentials for the sandbox.
