Connect to localhost service from Zoom App

me and my team are working on a Zoom Application that specifically needs to connect to an application running on the same machine.

When Zoom App starts we need to know, if, on the same computer, another application we developed is running. We usually do this with a HTTP call to localhost:54322

Being a ‘localhost’ we cannot have a valid ssl certificate. We tried in many ways but each call ends with mixed content error. We also tried to use websocket (to localhost) without any luck.

We need that because it is the only way to bind zoom user to our application user.

Is there a way to perform this operation?
