To enable LinkedIn Auth for your project, you need to set up a LinkedIn OAuth application and add the application credentials to your Supabase Dashboard.

Overview

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

Access your LinkedIn Developer account

Find your callback URL

<$Partial path="social_provider_setup.mdx" variables={{ "provider": "LinkedIn" }} />

Create a LinkedIn OAuth app

  • Go to LinkedIn Developer Dashboard.
  • Click on Create App at the top right
  • Enter your LinkedIn Page and App Logo
  • Save your app
  • Click Products from the top menu
  • Look for Sign In with LinkedIn using OpenID Connect and click on Request Access
  • Click Auth from the top menu
  • Add your Redirect URL to the Authorized Redirect URLs for your app section
  • Copy and save your newly-generated Client ID
  • Copy and save your newly-generated Client Secret

Ensure that the appropriate scopes have been added under OAuth 2.0 Scopes at the bottom of the Auth screen.

Enter your LinkedIn (OIDC) credentials into your Supabase project

<$Partial path="social_provider_settings_supabase.mdx" variables={{ "provider": "LinkedIn (OIDC)" }} />

You can also configure the LinkedIn (OIDC) auth provider using the Management API:

bash
# Get your access token from https://supabase.com/dashboard/account/tokens
export SUPABASE_ACCESS_TOKEN="your-access-token"
export PROJECT_REF="your-project-ref"

# Configure LinkedIn (OIDC) auth provider
curl -X PATCH "https://api.supabase.com/v1/projects/$PROJECT_REF/config/auth" \
  -H "Authorization: Bearer $SUPABASE_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "external_linkedin_oidc_enabled": true,
    "external_linkedin_oidc_client_id": "your-linkedin-client-id",
    "external_linkedin_oidc_secret": "your-linkedin-client-secret"
  }'

Add login code to your client app

<TabPanel id="js" label="JavaScript">

<$Partial path="create_client_snippet.mdx" />

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

js
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('<your-project-url>', '<sb_publishable_... or anon key>')

// ---cut---
async function signInWithLinkedIn() {
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider: 'linkedin_oidc',
  })
}
</TabPanel> <TabPanel id="flutter" label="Flutter">

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

dart
Future<void> signInWithLinkedIn() async {
  await supabase.auth.signInWithOAuth(
    OAuthProvider.linkedinOidc,
    redirectTo: kIsWeb ? null : 'my.scheme://my-host', // Optionally set the redirect link to bring back the user via deeplink.
    authScreenLaunchMode:
        kIsWeb ? LaunchMode.platformDefault : LaunchMode.externalApplication, // Launch the auth screen in a new webview on mobile.
  );
}
</TabPanel> <$Show if="sdk:kotlin"> <TabPanel id="kotlin" label="Kotlin">

When your user signs in, call signInWith(Provider) with LinkedIn as the Provider:

kotlin
suspend fun signInWithKaLinkedIn() {
	supabase.auth.signInWith(LinkedIn)
}
</TabPanel> </$Show> </Tabs>

<$Partial path="oauth_pkce_flow.mdx" />

<Tabs scrollable size="small" type="underlined" defaultActiveId="js" queryGroup="language"

<TabPanel id="js" label="JavaScript">

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

js
import { createClient } from '@supabase/supabase-js'
const supabase = createClient('<your-project-url>', '<sb_publishable_... or anon key>')

// ---cut---
async function signOut() {
  const { error } = await supabase.auth.signOut()
}

dart
Future<void> signOut() async {
  await supabase.auth.signOut();
}

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

}

LinkedIn Open ID Connect (OIDC)

We will be replacing the LinkedIn provider with a new LinkedIn (OIDC) provider to support recent changes to the LinkedIn OAuth APIs. The new provider utilizes the Open ID Connect standard. In view of this change, we have disabled edits on the LinkedIn provider and will be removing it effective 4th January 2024. Developers with LinkedIn OAuth Applications created prior to 1st August 2023 should create a new OAuth application via the steps outlined above and migrate their credentials from the LinkedIn provider to the LinkedIn (OIDC) provider. Alternatively, you can also head to the Products section and add the newly releaseSign In with LinkedIn using OpenID Connect to your existing OAuth application.

Developers using the Supabase CLI to test their LinkedIn OAuth application should also update their config.toml to make use of the new provider:

[auth.external.linkedin_oidc]
enabled = true
client_id = ...
secret = ...

Do reach out to support if you have any concerns around this change.
