In this section, we'll go through the steps for creating and configuring a LinkedIn application through the LinkedIn developers portal.
Step 1: Create your Social Network Application
Enter: https://www.linkedin.com/developer/apps/new and register a LinkedIn developer account.
On the landing page of the Instagram developers portal, click "Create application" and then fill in the required fields with the correct information.
Once your LinkedIn application is created, please send us the Client ID and Client Secret at firstname.lastname@example.org. This information can be found under Authentication > Authentication Keys. See below:
Step 2: Configure your application
Under Authentication > Authentication Keys, choose which user permissions your application will request.
We recommend choosing r_basicprofile and r_emailaddress.
Additionally, for LinkedIn partners (follow this link for information on becoming a LinkedIn partner). In order to acquire advanced permissions (r_fullprofile, r_contactinfo, rw_groups, r_networks) you'll have to fill out and submit this form.
Next, under Authentication > OAuth 2.0, enter your callback URL. This is where you should redirect the user when they complete the social login process. You are required to include the callback URL in the configuration settings of your application so that LinkedIn can confirm you own this URL and that it is secure.
