How can I connect my adalo app to IP restricted Server?

My app need to connected to the server, but Server has the policy only open to registered IP.
When Adalo app send aPI call, the IP for Adalo server is dynamic. it is not fixed IP. So I can connect to my parters server service.
And I found Mixpanel Token and is it unique data from my app? and Is it possible to send any unique data to server side?
Please give me an advice to solve this problem.

Thanks, folks
