Invalid Grant Type Powershell Invoke-WebRequest RRS feed

  • Question

  • I am writing a powershell script to request a access token. When I run it I am getting the error below for Invalid Grant type. I am not sure why (I am fairly new to powershell programming).

    Error:

    Invoke-WebRequest : Invalid grant type
    At C:\pwscripts\testps.ps1:34 char:1
    + Invoke-WebRequest -uri 'https://urlsite' -M ...
    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest], WebExc
       eption
        + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

    The code I am using:

    $BodyArray = @(
        @{
            grant_type= 'refresh_token'
            refreshToken= 'refres token here'
     }
    )

    $BodyArray_Json = ConvertTo-Json -InputObject $BodyArray

    (New-Object System.Net.WebClient).Proxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials

    Invoke-WebRequest -uri 'https://urlsite' -Method POST -body $BodyArray_Json -Headers @{'Accept' = 'application/json';'Content-Type' = 'application/json';}
