$ids | % {
$PolicyID = $_

$headers = @{ "Authorization" = "Bearer $apiKey" }
$url = "https://console.automox.com/api/policies/$policyID$middle$orgID"
$response = (Invoke-WebRequest -Method Get -Uri $url -Headers $headers).Content

$policyfinal = $response.replace("$changefrom","$changeto")


$body = @"
$policyfinal
"@


$headers = @{
    "Authorization" = "Bearer $apiKey"
    "Content-Type" = "application/json"
  }
$url = "https://console.automox.com/api/policies/$policyID$middle$orgID"
Invoke-WebRequest -Method Put -Uri $url -Headers $headers -Body $body
}

This iterates through any policy that has a name that includes “Windows Policy” and will update the priority of the policy updates from “high” to “low”.  While this is a very specific niche use-case, the overall code/script itself can easily be modified to update any other part of a policy through the API.
