Hi there, I’m building a Zoom App that runs inside a Zoom meeting and needs to fetch real-time data (probabilities) from a local `.exe` running on `localhost`. Specifically, I’m trying to use: ```auto fetch('http://localhost:5000/probabilities') ``` Will this work when users install and run my Zoom App on their machines? In other words, can a Zoom App inside the meeting sandbox access a local server (e.g., Flask API running on `localhost:5000`)? Thanks! ---

hi @Steve7 , You can not run any code on a localhost url. So, that includes calling a local URL. If you want to talk to a localhost connection, then you will need to set up something like a JS server and call for commands that way. e.g. I set up an app where I called a treamdeck app on localhost using a JS server. hope that makes sense John ---
