LinkedIn API — Base URL, Auth & Endpoints

The LinkedIn API (v2) allows applications to post articles and rich media to LinkedIn, access member profiles (with consent), manage company page content and analytics, retrieve job listings, and run marketing campaigns. The API uses OAuth 2.0 for all user-scoped operations. Most endpoints require an approved LinkedIn Partner Program application for production access. Widely used for social media management tools, recruiting platforms, and B2B marketing automation.
