Overview

The LinkedIn API enables you to integrate LinkedIn Login, share content, and access professional profile data for authenticated users. It is built on OAuth 2.0 and is gated — most advanced endpoints require applying for LinkedIn Partner Program access. Beginners can use the Sign In with LinkedIn and basic profile endpoints without special approval.

💡

Beginner Tip

Start with the Sign In with LinkedIn flow using OpenID Connect to authenticate users — it gives you basic profile info like name, email, and photo without needing partner access. Most other LinkedIn API features require approval from LinkedIn partner program.

Common Errors & Troubleshooting

401 Unauthorized: invalid token Access token has expired; LinkedIn tokens expire after 60 days

✓ LinkedIn does not support refresh tokens by default — direct the user to re-authenticate to get a new access token

403 Insufficient permissions The requested endpoint requires a scope not granted or requires partner access

✓ Check which scopes are available to your app tier; most advanced endpoints require LinkedIn Partner Program approval

400: Invalid redirect_uri The redirect URI in your OAuth request does not match what is registered in your LinkedIn app

✓ Add the exact redirect URI including http or https and any trailing slashes to the Authorized redirect URLs list in your LinkedIn Developer app settings
