use RESTAPI in a powershell script

Hi All,

i need help to create a powershell script using REST API command.

i don’t found a lot of documentation for the specific use of REST API in powershell.

in the community in have found a sample for POST LOGIN 

$headers = @{}
$headers.add("Accept", "application/json")
$headers.add("Content-Type","application/json")

$username = "user"
$password = "passwordtoencode"
$encodePassword = [convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes($password))

$body = @{username=$username;password=$encodePassword;}

$response = Invoke-RestMethod 'http://hostname/webconsole/api/Login' -Method POST -Headers $headers -Body $($body | ConvertTo-Json )

$response

But somenone have sample for all kind of REST API sample ?

Thank in advance

Christophe
