Calling your APIs with Auth0 tokens

Add LinkedIn Login to Your App

This guide will show you how to add functionality to your web app that allows your users to log in with LinkedIn. Along the way, you will also learn how to get an Access Token that will allow you to access the LinkedIn API.

OIDC-conformant pipeline and tokens

1. Create your app in LinkedIn

Log in to the LinkedIn Developer portal, and click Create App.

You'll be asked to provide basic details about your app, including your:

  • App name
  • Company
  • Privacy policy URL
  • Business email
  • App logo

You'll also need to select the products you'd like to add/integrate into your app. By default, you'll get the abilities to Share on LinkedIn and Sign In with LinkedIn. You can, however, also use the Marketing Developer Platform.

Finally, indicate that you agree to LinkedIn's legal terms, and click Create App.

Access vs. ID Tokens

Client ID and Client Secret

LinkedIn automatically generates a Client ID and Client Secret for your application; you can find these on the app's Auth screen under Application credentials. Make a note of these values, since you'll need to provide them to Auth0 at a later point.


OAuth 2.0 Settings

You will need to provide the appropriate Redirect URL for your app to LinkedIn. You can do this via the Auth screen under OAuth 2.0 Settings. Click the pencil icon, then click Add redirect URL. When prompted, provide the following:

Field Description
Redirect URLs https://YOUR_DOMAIN/login/callback

2. Create and enable a connection in Auth0

Set up the LinkedIn social connection in Auth0. Make sure you have the Client ID and Client Secret generated in Step 1.

3. Test the connection

You're ready to test your connection.

Access LinkedIn's API

Once a user successfully authenticates, LinkedIn will include an scopesAccess Token in the user profile it returns to Auth0. You can use this token to call LinkedIn's API.

To get the LinkedIn Access Token, you must retrieve the full user's profile using the Auth0 Management API and extract the Access Token from the response. For detailed steps, see Call an Identity Provider's API.

Using the token, you can call LinkedIn's API following LinkedIn's documentation.

Optional: Get a audienceRefresh Token from LinkedIn to refresh your Access Token once it expires. To ensure your application is secure, pay close attention to the restrictions on using Refresh Tokens.

On 1 March 2019, LinkedIn replaced their sign-in API with version 2.0, and all LinkedIn connections in Auth0 were automatically updated to use this version. To learn more, see Migration to LinkedIn API V2.
