Code:
#variables
$user, $pass, $env = 'admin', '**********, 'dev118854'
$file_path = "C:\temp\test.csv"
#Headers
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user, $pass)))
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add('Authorization',('Basic {0}' -f $base64AuthInfo))
$headers.Add('Accept','application/json')
$headers.Add('Content-Type','application/json')

$method = "get"
$response = Invoke-RestMethod -Headers $headers -ContentType "application/json" -Method $method -Uri $uri
