Notes

  • The API supports two post URL formats:
    • Feed updates: https://www.linkedin.com/feed/update/urn:li:activity:...
    • share url: https://www.linkedin.com/posts/..
  • Results are paginated with a maximum of 50 reactions per page
  • The profile picture URL may be null if not available or if the user has no profile picture
  • Connection degree shows your network relationship with the reactor (1st, 2nd, or 3rd degree connection)
  • Pagination Mode vs. Total Results Mode:
    • Total Results Mode: Use the total_results parameter to specify how many reactions you want (default)
    • Pagination Mode: Use start_page and end_page parameters to fetch specific pages of results
    • Credit usage in pagination mode is based on the number of pages fetched (1 credit per page)
    • When using pagination mode, total_results parameter is ignored
  • The total_available_results field shows the total number of reactions available on the post
  • Some reaction information may be limited based on:
    • Your connection level with the reactor
    • The reactor’s privacy settings
    • The post’s visibility settings
  • Rate limits apply to reaction retrieval requests
