Form List API

We have an offsite license, and I am developing a web services integration. I have successfully added a reference to the Portal API and am trying to use the GetFormsList function. The first parameter is accountName. I have tried passing it the API access token, my e-mail (repeated in the e-mail address variable), my AD account both with and without domain (even though the implementation is not configured for directory services) as well as my first and last name. I also tried all of the above with setting the out bound access token to my API key as well as leaving it blank. I only ever receive a response of “1” with a consistent token, which appears to be “Invalid Username Or Password”.  I have searched both the online documentation as well as the forums and have found no other reference or description of accountName other than the web service definition.

Any help would be appreciated.
