Private routing environment: Sending uplinks to HTTP endpoint

Hello,

I’ve set up a private routing environment on my personal machine. I’ve tried to send uplinks from a device and the handler receives it successfully. My question is: can I send the uplinks from the handler to somewhere else? (say an http endpoint), or maybe even save the uplink to some file locally?. I know that I can send to an http endpoint in the TTN console using integration, but that’s in case my application is registered to a public handler not a private one. So any ideas?
