React to LinkedIn Post
React to a LinkedIn post with one of six reaction types: like, celebrate, support, love, insightful, or funny. Reacting again simply overwrites your existing reaction without error, so the action is safe to repeat. A safety limit of 100 reactions per day protects your account from looking automated.
Example prompt: React with insightful to post urn:li:activity:7012345678901234567
{
"post_id": "urn:li:activity:7012345678901234567",
"reaction_type": "insightful",
"status": "reacted"
