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#

Setting up Slack logins for your application consists of 3 parts:

The next step requires a callback URL, which looks like this: https://<project-ref>.supabase.co/auth/v1/callback

Go to your Supabase Project Dashboard
Click on the Authentication icon in the left sidebar
Click on Providers under the Configuration section
Click on Slack from the accordion list to expand and you'll find your Redirect URL, you can click Copy to copy it to the clipboard

Under Create an app...:

Under App Credentials:

Under the sidebar, select OAuth & Permissions and look for Redirect URLs:

Under Scopes:

Add the following scopes under the User Token Scopes: profile, email, openid. These scopes are the default scopes that Supabase Auth uses to request for user information. You can add any additional scopes that you may need as well.

Go to your Supabase Project Dashboard
In the left sidebar, click the Authentication icon (near the top)
Click on Providers under the Configuration section
Click on Slack from the accordion list to expand and turn Slack Enabled to ON
Enter your Slack Client ID and Slack Client Secret saved in the previous step
Click Save

When your user signs in, call signInWithOAuth() with slack as the provider:

async function signInWithSlack() {
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider: 'slack',
  })
}

When your user signs out, call signOut() to remove them from the browser session and any objects from localStorage:

async function signout() {
  const { error } = await supabase.auth.signOut()
}
