Authorize.net CIM - Why The API user name is invalid or not present

Question

I have created an application using authorize.net CIM. When using the app in test mode everything works fine. When I switch from test mode to live mode and paste in the correct user id and transaction key, it says: The API user name is invalid or not present.

It makes no sense. I'm 100% that the api user name and transaction key are correct.

I'm using the CIM codeigniter library. Here's the code dealing with the setup and initialization of CIM...

Answer 1

I finally figured this out after hours of pulling my hair out!

There is some errors with the if statement logic in the __construct of the Library Class. What happens is that when it checks for the config options, if your test mode is set to FALSE then it won't initialize... because then you are passing a FALSE value to the if statement (this happens around line 49 in my file). What you can do to fix it is just remove that "test mode" check from the if statement.

This is what it would look like:

if($this->_CI->config->item('authorizenetname') && $this->_CI->config->item('authorizenetkey'))
{
    $this->initialize($this->_CI->config->item('authorizenetname'), $this->_CI->config->item('authorizenetkey'), $this->_CI->config->item('authorizenettestmode'));
}

I know this answer is kind of late in the game, but hope it helps.
