API button not available?

Hello,

I am investigating to see if I can manually add some missing functionality to support center. I see there is an API availble to communicate with support center. So I was checking to see how it works.

The manual gives this information to access the API:
To access the API configuration wizard in SupportCenter Plus,

Click the Admin tab in the header pane to open the configuration wizard page.
Click API icon under Organizational Settings block.

If you have enabled multi tenancy through Business Unit, click Global Settings tab - > API under Application Settings block. The list view displays the API applications configured in SupportCenter Plus.

If I press the 'Global Settings' tab from Admin then I only see the following icons:
Organization Details, Mail Server Settings, Customer Portal Settings, Windows Domains, Twitter Settings.

So where can I find my API icon?

BTW: The most important option that I was looking for in the API (Add/Edit Time Entry) is not available I see.... :(
