Send Email with mailgun

I am extremely new with Node-RED and I am struggling with translating mailguns curl to http request in Node-RED. I found a couple examples on here but nothing that looks like there curl command.

Any help would be greatly appreciated.

curl -s --user 'api:ENTER_API_KEY_HERE' \
	 https://api.mailgun.net/v3/sandbox.mailgun.org/messages \
	 -F from='Mailgun Sandbox <postmaster@sandbox.mailgun.org>' \
	 -F to='Dereck Radford <dereck.radford@domain.com>' \
	 -F subject='Hello Dereck R \
	 -F template='waitingforpayment' \
	 -F h:X-Mailgun-Variables='{"test": "test"}'
