How to set up social connection with Slack


Adding social connection with Slack to your app with Clerk is done in a few steps - you only need to set the Client ID, Client Secret and Authorized redirect URL in your instance settings.


Please note that Sign in with Slack doesn't support any additional OAuth scopes other than openid, email, profile, which are requested by default

To make the development flow as smooth as possible, Clerk uses preconfigured shared OAuth credentials and redirect URIs for development instances - no other configuration is needed.

For production instances, you will need to generate your own Client ID and Client secret using your Slack account.


The purpose of this guide is to help you create a Slack OAuth app - if you're looking for step-by-step instructions using Clerk to add social connection (OAuth) to your application, follow the Social connection (OAuth) guide.
