Create an empty topic via API

Is it possible to create an empty topic (without any posts)?
I think this not allowed bc in API description the raw field is required

That’s right.

What are you trying to accomplish by creating a topic that violates the definition of a topic?

I have a list of posts in my app and what I’m trying to do is add a topic (discussion) to every post
So I thought about using discourse
My point is when I create a new post (Commercial) I want to create a topic for it at the same time
After that, all comments will be posts within the topic

Maybe see Embedding Discourse Comments via Javascript

sorry, this not what I need.
I m using discourse server-side
