1. Go to the LinkedIn Developers page at https://developer.linkedin.com.
  2. Create an application, following the instructions at https://www.linkedin.com/developers/apps.
  3. Enter the following information:
    • App name: A unique name for the application. Must be fewer than 50 characters.
    • Company: The company to be associated with your application.
    • App logo: The logo that users will see when they authenticate with your application.
  4. Click Create app.
  5. On the Auth page, copy the client ID and client secret to a secure location.

    You can always access the client ID and client secret later from the Auth page.

  6. In the OAuth 2.0 Settings section, you'll see a field for Redirect URLs, which is the path in your application that users are redirected to after they have authenticated with LinkedIn. Leave this value blank for now.
