# Slack overview & authentication

## Overview

Our Slack integration allows you to connect to the Slack API and post messages to Slack.

## Installation

<CodeGroup>
  ```bash npm
  npm install @trigger.dev/slack@latest
  ```

  ```bash pnpm
  pnpm install @trigger.dev/slack@latest
  ```

  ```bash yarn
  yarn add @trigger.dev/slack@latest
  ```
</CodeGroup>

## Authentication

Slack supports OAuth.

## OAuth

To use OAuth you can connect to Slack via the Trigger.dev [web app](https://cloud.trigger.dev). Click 'Integrations' in the side panel of any project, and configure Slack with the ID you want to use in your job and the required [scopes](https://api.slack.com/scopes).

```ts
import { Slack } from "@trigger.dev/slack";

const slack = new Slack({
  id: "slack",
});
```

## Tasks

Once you have set up a Slack client, you can use it to create tasks.
