Sample Input

{
    "posts": [
        "7302346926123798528",
        "https://www.linkedin.com/feed/update/urn:li:activity:7302346926123798528/"
    ],
    "sortBy": "relevant",
    "pageNumber": 1,
    "includeReplies": true,
    "includeReactions": true,
    "reactionType": "ALL",
    "commentsLimit": 50,
    "reactionsLimit": 100
}

Sorting

• Relevant (default) — LinkedIn's own ranking of the most engaging comments
• Recent — chronological order, newest first

Pagination

Results come back in pages of 100. Use pageNumber to step through them:

• pageNumber: 1 → results 1–100
• pageNumber: 2 → results 101–200
• pageNumber: 3 → results 201–300

Pagination applies to both comments and reactions independently. Each page returns up to 100 comments and up to 100 reactions.

Output

Every item in the dataset includes a data_type field ("comment", "reaction", or "error") so you can easily filter by type.
