Notes

  • Two Access Methods: You can retrieve conversation messages using either:
    • LinkedIn Profile URL: The API will first find the conversation ID associated with that profile
    • Direct Conversation ID: Skip the profile lookup and access the conversation directly
  • Parameter Requirements: Either linkedin_url OR conversation_id must be provided (not both required)
  • Messages are returned in chronological order (most recent first)
  • The timestamp is in milliseconds since epoch
  • Cursor-based Pagination:
    • First request: Omit the cursor parameter to get the most recent messages
    • Subsequent requests: Pass the next_cursor value from the previous response as the cursor parameter
    • End of results: When has_next_page is false, there are no more messages to fetch
    • Use total_results to control how many messages are returned per request (default: 10)
  • When using linkedin_url, the API first retrieves the conversation ID for the specified profile, then fetches the messages
  • When using conversation_id, the API directly fetches messages from that conversation
  • This endpoint can only retrieve messages with profiles you’ve already had a conversation with
  • Historical messages may be limited by LinkedIn’s data retention policies
  • The profile_url field is only included in the response when it was provided in the request

​
Pagination Example

// First request - get most recent messages
{"linkedin_url": "https://linkedin.com/in/example", "total_results": 5}

// Next page - use cursor from previous response
{"linkedin_url": "https://linkedin.com/in/example", "total_results": 5, "cursor": "1745266498889"}
