# LinkedIn > LinkedIn is a professional networking platform whose public APIs span consumer identity (Sign In / Share / Verified on LinkedIn), B2B marketing (campaigns, audiences, conversions, analytics), talent solutions (job posting, Recruiter System Connect), learning, Sales Navigator, compliance archiving, and regulatory data portability. APIs are built on the Rest.li framework (URN identifiers, X-Restli-Protocol-Version 2.0.0) and are date-versioned via the Linkedin-Version (YYYYMM) header. This llms.txt was generated by API Evangelist from the apis.yml catalog and captured artifacts in this repo (method: generated, 2026-06-20).
