    1 2 3 4 5 $headers = @{ "Authorization" = "Basic " + [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("USERNAME:PASSWORD")) "Content-Type" = "application/json" } Invoke-WebRequest -Uri "https://JIRA.EXAMPLE.COM/rest/jira-mail-plugin/1.0/outgoingMail/config" -Method Put -Headers $headers -Body '{"enabled": "false"}' -UseBasicParsing
