In this guide we will show you how you can enable the Slack integration on your on self-hosted Lightdash server.

​
Create a new Slack app on your organization

First we will have to create a Slack APP https://api.slack.com/apps?new_app=1 You can select From an app manifest to make it easier.
Then select the workspace you want to enable this into. Later you can enable distribution if you want to use a different Slack workspace.
Then copy this manifest to allow URL unfurls in your app. Make sure you update your-lightdash-deployment-url.com in the manifest below (for example, app.lightdash.cloud). 
display_information:
  name: Lightdash

  background_color: '#7262ff'

Copying credentials

Now copy the following credentials from your new app. From Basic Information

​
Adding credentials to your local environment

Now you need to add the following environment variables to your Lightdash server using the credentials we previously copied
  • SLACK_CLIENT_ID: Client ID (make sure it is between quotes, so it is a string, not a number)
  • SLACK_CLIENT_SECRET: Client secret
