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](https://www.linkedin.com/developers/apps).
- Add your LinkedIn `API Key` and `API Secret Key` to your [Supabase Project](https://app.supabase.com).
- Add the login code to your [Supabase JS Client App](https://github.com/supabase/supabase-js).

## Steps

### Access your LinkedIn Developer account

- Go to [LinkedIn Developer Dashboard](https://www.linkedin.com/developers/apps).
- 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](https://app.supabase.com).
- 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](https://www.linkedin.com/developers/apps).
- 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](https://app.supabase.com).
- 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 `API Key` (`client_id`) and `API Secret Key` (`client_secret`) saved in the previous step.
- Click `Save`.

### Add login code to your client app

The JavaScript client code is documented here: [Supabase OAuth Client Code](/docs/reference/javascript/auth-signin#sign-in-using-third-party-providers).

```js
const { user, session, error } = await supabase.auth.signIn({
  provider: 'LinkedIn',
})
```

Add this function which you can call from a button, link, or UI element.

```js
async function signInWithLinkedIn() {
  const { user, session, error } = await supabase.auth.signIn({
    provider: 'LinkedIn',
  })
}
```

To log out:

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