LinkedIn Post Reactions API questions

How do I get a list of people who liked a LinkedIn post?

Send the post’s activityUrn, urn:li:activity:<id>, where the id is the long number after "activity" in the post’s link. Each person comes back with name, headline, profile link, profile picture and the reaction they chose, up to 100 per call.

Can I turn post engagement into a lead list?

Yes. People who react to a post about a problem often have that problem. Collect them from your own or a competitor’s posts, filter by headline, and open their full profiles with the LinkedIn Profile API.

How do I get everyone who reacted to a LinkedIn post?

Each call returns up to 100 people. Set start to the number you already have, 100, then 200 and so on, until no more come back.

Send a POST request to https://api.bridgly.app/linkedin/get-post-reactions with activityUrn in the JSON body and your API key in the Authorization header.
