Can't write to custom logs

I am new to Intune.   I have created a log analytics workspace.   Using PowerShell I want to write to this location.    My web address is always wrong, regardless of what I use.   PowerShell gives me this error:

Invoke-WebRequest : The remote name could not be resolved:

I am trying to use this code that I found online.  

# Log analytics part

    LogType    = $LogType 
}
$LogResponse = Post-LogAnalyticsData @params
	

No matter what I try for $CustomerID and URL it fails.  For CustomerID I have tried my subscription ID, my tenant ID and the Workspace ID and nothing works.   


Question:  Do I need to pre-create a custom log in Azure?  If so how?     It askes for a custom script and I don't know what to use.

Any help would be great.
