ToolJet supports integration with your Slack workspace, enabling you to automate and interact with Slack directly from your applications. By connecting Slack as a datasource, you can perform operations such as sending messages to channels, retrieving message history, and more.

## Connection

ToolJet offers two ways to connect with Slack:
- [Custom Slack App](#custom-slack-app): Offers full control over permissions, OAuth scopes, and configuration.
- [ToolJet Slack App](#tooljet-slack-app): Provides a quick setup where you just need to authorize it with your Slack workspace, and no need to manually configure OAuth scopes. This option is available only in ToolJet Cloud.

### Custom Slack App

1. Add a new **Slack** data source in ToolJet.

2. Select **Custom slack app** from the dropdown and copy the Redirect URL displayed at the bottom. <br/>

7. In the same tab, scroll down to Scopes and add the necessary OAuth scopes, including the mandatory scopes required by ToolJet (as mentioned on the Slack Data Source configuration page).

8. Return to the ToolJet Slack Data Source configuration page and enter the Client ID and Client Secret obtained in step 5.

9. Click **Connect to Slack**. You will be redirected to Slack to authorize the app for your workspace. <br/>

10. After authorization, click **Save data source** in ToolJet. This will add a new Slack bot to your workspace.

11. Optionally, customize the bot’s profile (icon, name, description, etc.) from the Slack API page.

After successful configuration, a new bot will appear in your Slack workspace. You can add this bot to different channels to perform operations from ToolJet.
