#variables
$org = "<api url here>"
$token="<api token here>"
$filePath = "D:\Downloads\logs\test2.json"
#format the date and append 00:00:00
$fromTime = Get-Date -Format s
$fromTime = $fromTime.Substring(0,10) + "00%3A00%3A00Z"
#format the date and append 23:59.59
$toTime = Get-Date -Format s
$toTime = $fromTime.Substring(0,10) + "T23%3A59%3A59Z"

### Set $uri as the API URI for use in the loop
$uri = "$org/api/v1/logs?until=$toTime&limit=20&sortOrder=DESCENDING&q=&since=$fromTimeT00"

### Define $allLogsas empty array
$allLogs = @()

### Use a while loop and get all users from Okta API
