Automating installing license server key pack on windows server using power shell

HI,

I want to  automate the following steps  after obtaining the license key pack id from the Remote Desktop Services Licensing Web site.

•1) "In the Install Licenses Wizard, on the Obtain Client License Key Packpage, enter the license key pack ID in the boxes provided, and then click Next. The RDS CALs are installed on your license server.

•2) On the Completing the Install Licenses Wizardpage, click Finish. The license server can now issue RDS CALs to clients that connectto a Remote Desktop Session Host (RD Session Host) server."

Is "unit32 InstallLicenseKeyPack( [in] string sLlicensKeyPackId, [out]uint32 KeyPackId) the right API to use ?

What is the use of the KeyPackIdreturned by the API ?
How to call this using powershell ?

Thanks for the help
