The sample PowerShell script below processes through a series of files in a folder, and uploads the file to the profile picture API endpoint. This assumes that the images are named with the person's ID as the file name, and the folder only contains image files

        $personId = $_.BaseName

        $baseUri = $interactUrl + "/api/umi/" + $profileSourceId + "/upload/umiid/" + $personId + "/picture"

        SendFile $baseUri $_.FullName
