LinkedIn OAuth setup overview

Setting up LinkedIn logins consists of three parts: Create and configure a LinkedIn Project and App on the LinkedIn Developer Dashboard, add the LinkedIn (OIDC) client_id and client_secret to the Supabase Dashboard, and add login code to the Supabase JS Client App.

LinkedIn OIDC provider name in signInWithOAuth

When calling signInWithOAuth() to enable LinkedIn login, use 'linkedin_oidc' as the provider parameter.

LinkedIn OAuth app creation steps

To create a LinkedIn OAuth app: Go to LinkedIn Developer Dashboard and log in, click 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 Request Access, click Auth from the top menu, add your Redirect URL to the Authorized Redirect URLs section, and copy and save the generated Client ID and Client Secret. Ensure appropriate scopes have been added under OAuth 2.0 Scopes at the bottom of the Auth screen.

Management API configuration for LinkedIn OIDC

LinkedIn (OIDC) auth provider can be configured using the Management API with a PATCH request to https://api.supabase.com/v1/projects/{PROJECT_REF}/config/auth with the following JSON body: external_linkedin_oidc_enabled (boolean), external_linkedin_oidc_client_id (string), external_linkedin_oidc_secret (string). Authentication requires a Bearer token from https://supabase.com/dashboard/account/tokens.

LinkedIn OIDC provider replaces legacy LinkedIn provider

Supabase is replacing the legacy LinkedIn provider with a new LinkedIn (OIDC) provider to support recent changes to LinkedIn OAuth APIs and the Open ID Connect standard. The legacy LinkedIn provider edits were disabled and it will be removed effective 4th January 2024. Developers with LinkedIn OAuth Applications created prior to 1st August 2023 should create a new OAuth application or add the Sign In with LinkedIn using OpenID Connect product to their existing application.

Supabase CLI config for LinkedIn OIDC

In config.toml for Supabase CLI, configure LinkedIn OIDC auth provider using: [auth.external.linkedin_oidc] with fields enabled (boolean), client_id (string), and secret (string).
