Notes

  • The API supports LinkedIn post URLs in various formats
  • Results are paginated with configurable page ranges when using pagination mode
  • The profile picture URL may be null if not available
  • Connection degree shows your network relationship with the reactor
  • Pagination Mode vs. Total Results Mode:
    • Total Results Mode: Use the total_results parameter to specify how many reactions you want (default)
    • Pagination Mode: Set use_pagination to true and use start_page and end_page parameters
  • Rate limits apply to reaction extraction requests
  • The total_available field shows the total number of reactions available on the post
