Copilot for Security Plugin

Hi everyone,
I'm trying to develop a plugin in Copilot for Security with format=API. My plugin has to take a security incident from my SIEM and generate a report, following my personal template.
Is it possible to let Copilot for Security understand the placeholders he has to fill? I want to generate something more structured than a simple GPT prompt, in order to be sure that the output is the one I actually want.

This is my manifest

Thanks everyone!

Edit: In my plugin I tried to split up my incident into: id, name, body, follow-up actions, so that Copilot for Security had to send these information to my web server.
This is its output: Post request to https://lnkd.in/d49cXrEP failed with with HTTP status: 400 and exception: System.Net.Http.HttpRequestException: Request failed with status code BadRequest.
