Session Management, deployment and argument passing

[HarmonyV]

Hi there, I'm a developer (mainly front-end), and for my current app, I was planning to create a custom agent to simplify my work.

I finally managed to build an MVP that I would like to deploy. The issue is that

A: I only have basic (if at all) knowledge in Python (primarily work in Dart) and
B: Assuming I deployed the agent with Vertax AI, how would I go about communicating with it from my client app (built with Flutter) via HTTP requests while passing in session_id, user_id, etc?

I've seen Brandon's new voice agent video and hoped to get some insights, and while it was extremely helpful, the agent was technically running locally.

At least to me, it feels like most resources (that I found, maybe I didn't look thoroughly enough) skip that point after showing the deployment nor show how to pass key arguments.

Any help is much appreciated.
