Login with Slack
To enable Slack Auth for your project, you need to set up a Slack OAuth application and add the application credentials to your Supabase Dashboard.
Overview
The Slack OAuth provider supported by Supabase uses Slack's Legacy OAuth API. If you created an OAuth app on Slack recently, some of the scopes specified may not work with the Slack OAuth provider on Supabase. You can refer to the list of supported scopes for the legacy OAuth app and this github issue for future updates.
Setting up Slack logins for your application consists of 3 parts:
- Create and configure a Slack Project and App on the Slack Developer Dashboard.
- Add your Slack
API KeyandAPI Secret Keyto your Supabase Project. - Add the login code to your Supabase JS Client App.
