How to post in chat room using API

[Spin0us]

Hi there,

I'm working on a script that interact with NodeBB using API. I need to create a new chat room between 2 users and post content in it. In the API documentation, there's some data concerning "Accessing a chat room" and "Getting a chat room", but in write api there's nothing at all.

Is it currently impossible to post content in the chat room from the api?

I'm using NodeBB v1.17.0.
Api key created in admin panel. No problem to read chat room but writing failed.

{
    "status": {
        "code": "not-found",
        "message": "Invalid API call"
    },
    "response": {}
}
