With InterWorx, a key is used for communicating with the API. Therefore when configuring an InterWorx server inside WHMCS, all you need to do is enter the API Key into the Access Hash field. Username and password are not required.
Packages are then configured by entering the package name as it appears in InterWorx and the theme to set as the default for the new account. Both the package name and theme name should be entered all in lowercase or it will result in errors occuring.
If WHMCS is installed on the same InterWorx server that you will be setting up accounts on...
When as part of the account creation process InterWorx restarts apache, it will kill the WHMCS process, causing a problem. To prevent that, edit /usr/local/interworx/iworx.ini, and change the line
force_graceful="0"
to
force_graceful="1"
