How this service works
Fetches paginated reactions of a specific type for a LinkedIn post. Each page contains up to 10 reactions. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.
Output
Returns a paginated list of up to 10 reactions for the specified LinkedIn post and reaction type, including details about each person who reacted (profile info, reaction type), and a cursor for fetching the next page.
Example use cases
Identify warm leads from post engagement
“Pull up everyone who reacted to my latest LinkedIn post with a 'celebrate' reaction — I want to reach out to people who are genuinely excited about what we're doing.”
Track influencer post performance metrics
“Show me the first batch of 'insightful' reactions on this post so I can see which thought leaders found our content valuable.”
Build targeted outreach list by reaction type
“Grab all the 'like' reactions from our company announcement post and page through them — I need to identify engaged followers for a personalized outreach campaign.”
Technical details
Endpoint
POSThttps://mpp.orthogonal.com/fiber/v1/linkedin-live-fetch/post-reactions?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to enumerate and analyze who has reacted to a specific LinkedIn post, broken down by reaction type. Ideal for lead generation, engagement tracking, or identifying warm prospects who have shown interest in a post. Prefer this over profile-based endpoints when your starting point is a LinkedIn post rather than a person or company.
Side effects
- Invalid or inaccessible LinkedIn post URL returns an error
- Unsupported reaction type enum value causes a validation error
- Expired or invalid pagination cursor results in an error
- Post has no reactions of the requested type, returning an empty list
- Rate limit exceeded returns a 429 error
- Network timeout for posts with very large reaction counts
