Endpoint

GET /api/v1/profile/comments

This endpoint returns the comments a member has made, anywhere — each one paired with the full context of the post it was made on (its text, its author, its media and its engagement counts).

Do not confuse it with Get Post Comments, which goes the other way round: that one takes a post and returns the comments left on it. This one takes a profile and returns the comments that profile wrote.

Authentication

Include your API key in the request header:

X-API-Key: your-api-key-here

Parameters

string

required

The professional profile whose comments to fetch. Accepts any of:

Profile URN, recommended for consistency: a profile’s public identifier (slug) can change over time, the URN does not. Example: urn:li:fsd_profile:ACoAAA8BYqEBCGLg_vT_ca6mMEqkpp9nVffJ3hc
Public identifier (slug), also fine. Example: williamhgates
Profile URL. Example: https://www.linkedin.com/in/williamhgates (a trailing slash makes no difference)

The slug is the last path segment of a profile URL. Pass just the slug, not the /in/ prefix.Member profiles only: a company page URL or URN is rejected with a 400 error, free of charge.

integer

default:"10"

Number of comments to fetch per page.

Minimum: 1 — 0 or a negative value is rejected with 400
Maximum: 100 — a higher value is clamped, not rejected
Default: 10

integer

default:"0"

deprecated

Not supported on this endpoint. This feed is cursor-paginated and ignores offsets, so a non-zero start is rejected with 400 rather than silently returning the first page again. Use paginationToken.

string

Cursor for the next page. Pass back the paginationToken from the previous response, unchanged; omit it to start from the beginning. Keep paging while hasMore is true.Pass it back verbatim. A token this API did not issue is not rejected — it is forwarded, and the page comes back empty and still costs a credit, so do not construct or edit one.

Response

array

Array of comments the profile wrote, newest first. Each item carries the comment itself, its author, and the post it was written on.

Show Comment object

string

The text of the comment.

string

Unique identifier of the comment.

string

Permalink to the comment.

boolean

Whether the post’s author pinned this comment to the top of the thread.

string

ISO 8601 timestamp of when the comment was written.

object

Engagement on the comment itself.

Show Comment stats object

integer

Total reactions the comment received.

integer

Number of replies to this comment.

object

Per-type breakdown of the comment’s reactions.

Show Reactions object

integer

Like reactions.

integer

Support reactions.

integer

Love reactions.

integer

Insightful reactions.

integer

Celebrate reactions.

object

Who wrote the comment — the profile you asked for.

Show Commenter object

string

Full name of the commenter.

string

The line shown under the commenter’s name, usually their headline.

string

Professional profile URL of the commenter.

string

Profile picture URL of the commenter.

object

The post the comment was written on.

Show Post object

string

Text of the post.

string

Public permalink to the post.

string

The bare numeric activity id of the post, without any URN prefix.

string

ISO 8601 timestamp of when the post was published.

object

Who published the post.

Show Author object

string

Full name of the post author.

string

Professional headline of the post author.

string

Professional profile URL of the post author.

string

Profile picture URL of the post author, or null when they have none.

object

Engagement on the post.

Show Post stats object

integer

Total reactions the post received.

integer

Total comments on the post.

integer

Number of times the post was reshared.

object

Per-type breakdown of the post’s reactions: like, appreciation, empathy, interest and praise, all integers.

array

Images attached to the post, each with url, width and height. Always present; an empty array when the post carries no image — and also when it carries a video, because the two are mutually exclusive here.

object

Video attached to the post. Always present; null when the post has none. Carries url, duration and thumbnail, plus the raw upstream stream metadata (progressiveStreams, aspectRatio, entityUrn, provider, media) — treat those as additive and do not depend on them.

string

Token for fetching the next page of comments. Do not read its presence as “there is more”: decide on hasMore.

boolean

Indicates whether there are more comments to fetch.

Pagination

To collect a profile’s whole comment history:

Make an initial request without paginationToken
If hasMore is true, use the returned paginationToken in your next request
Continue until hasMore is false — not until a page comes back short

async function fetchAllProfileComments(profileUrl) {
  const allComments = [];
  let paginationToken = null;
  let hasMore = true;

  while (hasMore) {
    const params = new URLSearchParams({
      profileUrlOrUrn: profileUrl,
      count: '100'
    });
    if (paginationToken) {
      params.set('paginationToken', paginationToken);
    }

    const response = await fetch(
      `https://api.fetchin.io/api/v1/profile/comments?${params}`,
      { headers: { 'X-API-Key': 'your-api-key-here' } }
    );

    const data = await response.json();
    allComments.push(...data.comments);
    paginationToken = data.paginationToken;
    hasMore = data.hasMore;
  }

  return allComments;
}

Notes

This endpoint consumes 1 credit from your credit balance per API call, regardless of the count parameter value. Errors are free — with one exception: a 404 not found costs 1 credit. See Quotas.

Comments are returned in reverse chronological order (most recent first), and count is a ceiling rather than a promise: a page requested with count=100 routinely comes back with slightly fewer items. A short page is not the end of the feed — keep paging while hasMore is true, and never stop because you received fewer comments than you asked for.

Each item already embeds the post it was written on — its text, author, media and engagement counts — so you rarely need a follow-up call to Get Posts to make a comment actionable.

Use Cases

Buying-intent signals

Spot prospects commenting on your category, your competitors or your own content

Voice of the customer

Mine what a decision maker actually writes, in their own words, for personalized outreach

Network mapping

See whose posts a profile keeps engaging with to infer relationships and influence

Lead scoring

Score leads on how often, how recently and how substantively they comment

Authorizations

X-API-Key

string

header

required

Query Parameters

profileUrlOrUrn

string

required

The professional profile whose comments to fetch. Accepts a profile URN (recommended for consistency, since a profile's public identifier can change over time while the URN does not; example urn:li:fsd_profile:ACoAAA8BYqEBCGLg_vT_ca6mMEqkpp9nVffJ3hc), a public identifier/slug (also fine; example williamhgates), or a full profile URL (example https://www.linkedin.com/in/williamhgates; a trailing slash is ignored). The slug is the last path segment of a profile URL, so pass just the slug, not the /in/ prefix. Member profiles only: a company page URL or URN is rejected with a 400 error, free of charge.

Example:

"urn:li:fsd_profile:ACoAAA8BYqEBCGLg_vT_ca6mMEqkpp9nVffJ3hc"

count

integer

default:10

Number of comments to fetch per page (default: 10). Values above 100 are clamped to 100. This is a ceiling: a page can return slightly fewer items without meaning the feed is exhausted.

Required range: 1 <= x <= 100

start

integer

default:0

Not supported on this endpoint. This feed is cursor-paginated and ignores offsets, so a non-zero value is rejected with 400 rather than silently returning the first page again. Page with paginationToken instead.

Required range: x >= 0

paginationToken

string

Cursor for the next page: pass back the paginationToken from the previous response, unchanged. Omit it to start from the beginning. Pass it back verbatim: a token this API did not issue is NOT rejected here, it is forwarded, and the page comes back empty and still costs a credit. Keep paging while hasMore is true.

Response

Successfully fetched the comments the profile has written

comments

object[]

Comments the profile wrote, newest first.

Show child attributes

paginationToken

string

Token for fetching the next page. Only present when more comments are available.

hasMore

boolean

Whether more comments are available.
