I am working on this Powershell script to accept creating Github repo from my local pc to Github. But every time I try to enter description it fails and provides me this error. Could someone please help me out
Invoke-RestMethod : {"message":"Requires
authentication","documentation_url":"https://developer.github.com/v3/repos/#create"}

It looks like you're trying to use your Github API token with Basic Authentication, but according to the Github API v3 documentation that token is an OAuth token. Your header should look like this instead:
$head = #{
Authorization = 'token ' + $UserToken
}
You would use the Basic auth header if you were providing a base64 encoded string of your username and password (in the format of USERNAME:PASSWORD):
$basicAuthBytes = [System.Text.Encoding]::UTF8.GetBytes('USERNAME:PASSWORD')
$basicAuthBase64String = [Convert]::ToBase64String( $basicAuthBytes )
$head = #{
Authorization = "Basic ${basicAuthBase64String"
}
