The sample you shared is download audit log form Azure DevOps Server, the url is https://{your_server}/tfs/_api/_licenses/Export, username , password are your username and password to log on to TFS. Note: Do not forget add domain name before the username.

If you are using Azure DevOps Service, you can try this REST API and power shell script to save the Audit log.

$outfile = "{Local path}"
$connectionToken="{PAT}"
$base64AuthInfo= [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($connectionToken)"))
$AuditLogURL = "https://auditservice.dev.azure.com/{organization}/_apis/audit/downloadlog?format=csv&startTime={startTime}&endTime={endTime}&api-version=6.1-preview.1" 
$AuditInfo = Invoke-RestMethod -Uri $AuditLogURL -Headers @{authorization = "Basic $base64AuthInfo"} -Method Get –OutFile $outfile

Result:
