LinkedIn Profile Reactions

Give it a LinkedIn profile URL, get back the posts that person has reacted to.

What it does

• Returns the posts a profile has reacted to — liked, celebrated or reposted. A bare username works in place of the full URL.
• Each result carries the post’s author, content, engagement counts and URL.
• Useful for spotting what a prospect engages with before you reach out.
• Returns 3 posts by default, up to 50 per call via max_results.
• posted_limit narrows results by recency — any, 24h, week, month, 3months, 6months.

Direction matters here. This tool answers “what did this person react to”. To answer “who reacted to this post”, use linkedin_post_engagers instead — it takes a post URL and returns the accounts that engaged with it.

Parameters

How to use it

Show me what linkedin.com/in/janedoe has reacted to in the past month.

Get 25 posts she reacted to over the last 3 months. Group them by the
author of the post.

Pick the reaction that is most relevant to revenue operations and draft
a two-line opener referencing the idea in that post — not the fact that
she liked it.

Example prompts

Best prompting practices

• Say “what they reacted to”. Phrasing it as “who reacted” sends your client to the post-engagement tool, which answers the opposite question.
• Set posted_limit. A reaction from six months ago is not a timing signal. week or month is usually what you want for outreach.
• Raise max_results for pattern-finding. The default of 3 is a spot check; 25 shows a pattern. The cost is the same either way.
• Reference the idea, not the click. “I saw you liked a post” reads as surveillance. Referencing the argument in that post reads as relevance.
• Pair it with comments. Reactions show interest; linkedin_profile_comments shows opinion. Both are 0.2 credits.
