Login with LinkedIn

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:

Create and configure a LinkedIn Project and App on the LinkedIn Developer Dashboard.
Add your LinkedIn client_id and client_secret to your Supabase Project.
Add the login code to your Supabase JS Client App.

Access your LinkedIn Developer account#

Go to LinkedIn Developer Dashboard.
Log in (if necessary.)

Find your callback URL#

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 Settings icon at the bottom of the left sidebar.
Click on API in the list.
Under Config / URL you'll find your API URL, you can click Copy to copy it to the clipboard.
Now just add /auth/v1/callback to the end of that to get your full OAuth Redirect URI.

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 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

Enter your LinkedIn credentials into your Supabase Project#

Go to your Supabase Project Dashboard.
In the left sidebar, click the Authentication icon (near the top).
Click Settings from the list to go to the Authentication Settings page.
Enter the final (hosted) URL of your app under Site URL (this is important).
Under External OAuth Providers turn LinkedIn Enabled to ON.
Enter your client_id and client_secret saved in the previous step.
Click Save.

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

1async function signInWithLinkedIn() {
2  const { data, error } = await supabase.auth.signInWithOAuth({
3    provider: 'linkedin',
4  })
5}

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

1async function signout() {
2  const { error } = await supabase.auth.signOut()
3}
