# Slack

> The `settings` object for `slack` channels on POST /posts.

Channels whose `identifier` is `slack` validate the `settings` object below.
This page is generated from the application's own validation layer, so it
matches exactly what the server accepts.

Set `settings.__type` to `"slack"`.

## Fields

| Field | Type | Required | Notes |
| - | - | - | - |
| `channel` | string | **required** | Channel must be an id |

<Note>
  Settings are validated when a post is scheduled or published. Drafts skip this
  validation entirely - see [errors](/public-api/errors) for how failures are
  reported.
