# broadcast

`POST /system/broadcast/{path}`

### Asynchronously broadcast a message to the KAR runtime

Broadcast asynchronously executes a `POST` on the `path` endpoint
of all other KAR runtimes that are currently part of the application.
The runtime initiating the broadcast is not included as a recipient.
A `200` response indicates that the request to send the broadcast
has been accepted and the POST will eventually be delivered to all targeted
runtime processes.

## Path parameters

- `path` string, required

## Request body

- object

## Response `200`

A success message.

## Changes

- **2020-05-01** `d9f9d9f05f2d` — 1 info
  - endpoint added
