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.

1. Set up your app in LinkedIn

Log in to the LinkedIn Developer portal, and click Create App. During this process, LinkedIn will generate a Client ID and Client Secret for your application; you can find these on the app's Auth screen under Application credentials.

While setting up your app, make sure you use the following settings:

  • On the Auth screen, under OAuth 2.0 Settings, set the following parameters:
Field Description
Redirect URLs https://YOUR_DOMAIN/login/callback

Find your Auth0 domain name for redirects

If your Auth0 domain name is not shown above and you are not using our custom domains feature, your domain name is your tenant name, plus .auth0.com. For example, if your tenant name were exampleco-enterprises, your Auth0 domain name would be exampleco-enterprises.auth0.com and your redirect URI would be https://exampleco-enterprises.auth0.com/login/callback.

If you are using custom domains, your redirect URI will have the following format: https://<YOUR CUSTOM 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 Access 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 Refresh 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.
