Connect Apps to LinkedIn
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.
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
- 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.
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:
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
If you are using custom domains, your redirect URI will have the following format:
https://<YOUR CUSTOM DOMAIN>/login/callback.
Click Update to save your changes.
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.
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.
In December 2018, LinkedIn deprecated version 1.0 of their sign-in API. The final shutdown date we set for March 1st, 2019 then moved to May 1st, 2019. In June 2019, the current status is that "Applications requesting Version 1.0 APIs may experience issues as we begin to remove services."
LinkedIn replaced the sign-in API with version 2.0, which has some key differences.
We've added the option to set the LinkedIn API version for LinkedIn Connections. You can change the API version for a LinkedIn Connection through the Auth0 Dashboard by selecting a Strategy Version under the connection's settings.
