Endpoint

GET /api/v1/post/reactions

Authentication

Include your API key in the request header:

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

Parameters

string

required

Professional post URL or URN.Examples:

https://www.linkedin.com/posts/username_some-post-slug-1234567890-abcd
urn:li:activity:7287782484287606784
urn:li:ugcPost:7287782484287606784
urn:li:groupPost:4521873-7287782484287606784 — a post published in a group, as urn:li:groupPost:<groupId>-<postId> or any URL containing it. A post in a private group is visible to the group’s members only and answers 404 POST_NOT_FOUND, like a deleted post.

A repost without commentary answers with the original post’s reactions, as Get Post Comments does with comments.

integer

default:"100"

Number of reactions to fetch per page.

Minimum: 1
Maximum: 100
Default: 100

integer

default:"0"

Offset for pagination.

Default: 0

Response

array

Array of reactions on the post

Show Reaction object

string

The type of reaction. One of: LIKE, EMPATHY (Love), ENTERTAINMENT (Funny), INTEREST (Insightful), PRAISE (Celebrate), APPRECIATION (Support)

object

required

Who reacted: a member or a company page — read type.

Show Actor object

string

profile for a member, company for a company page.

string

required

urn:li:fsd_profile:<profileId> for a member, urn:li:fsd_company:<companyId> for a company page.

string

required

Full name of the member, or name of the page

string

required

The member’s headline, or the page’s subtitle line

string

required

https://www.linkedin.com/in/<publicId>/ for a member (keyed on the profile id when the public identifier is unknown), the company page URL for a page

string

required

Picture URL of the reactor. When the reactor has no picture, this is the source’s generic placeholder image — see picture.

object

The reactor’s real picture (or logo) as url, width, height, largest rendition. Absent when the reactor has no picture, which is how a placeholder profilePictureUrl is told apart from a real one.

string

Members only: the member’s public identifier (/in/<publicId>).

string

Members only: the profile id (ACoAA…), the same value as profileId in Fetch Profile.

string

Members only: the numeric member id.

string

Company pages only: the numeric company id.

string

Company pages only: the page’s public identifier (/company/<universalName>).

integer

Number of reactions the source reports for the post. Omitted when it reports none. A complete walk can end a few short of it, because the source withholds a few reactors.

boolean

Indicates whether there are more reactions to fetch.

Errors

See Error Handling for the full list of error codes and recommended handling.

400 — MISSING_PARAMETER, INVALID_URN
401 — INVALID_API_KEY
404 — POST_NOT_FOUND
402 — QUOTA_EXHAUSTED
429 — RATE_LIMITED
500 — INTERNAL_ERROR
503 — SERVICE_UNAVAILABLE

Pagination

To fetch all reactions from a post with many reactions, use offset pagination:

Make an initial request with start=0
If hasMore is true, increment start by count in your next request
Continue until hasMore is false

A complete walk can collect a few reactions fewer than total: the source withholds a few reactors from the list while still counting them.

async function fetchAllReactions(postUrlOrUrn) {
  const allReactions = [];
  let start = 0;
  const count = 100;
  let hasMore = true;

  while (hasMore) {
    const params = new URLSearchParams({ postUrlOrUrn, count: String(count), start: String(start) });

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

    const data = await response.json();
    allReactions.push(...data.reactions);
    hasMore = data.hasMore;
    start += count;
  }

  return allReactions;
}

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.

You can pass either a professional post URL (e.g. https://www.linkedin.com/posts/...) or a post URN (e.g. urn:li:activity:...). When a URL is provided, the API automatically resolves it to the correct activity URN.

Query Parameters

postUrlOrUrn

string

required

Professional post URL or URN: urn:li:activity:<id>, urn:li:ugcPost:<id>, a group post as urn:li:groupPost:<groupId>-<postId>, or any post URL containing one.

Example:

"https://www.linkedin.com/posts/username_post-slug-1234567890-abcd"

count

integer

default:100

Number of reactions to fetch (default: 100)

Required range: 1 <= x <= 100

start

integer

default:0

Offset of the first item to return. This endpoint pages by offset: advance start by the number of items you received. Keep requesting while hasMore is true; an empty page ends the list.

Required range: x >= 0

Response

total

integer

Number of reactions the source reports for the post. Omitted when it reports none. A complete walk can end a few short of it, because the source withholds a few reactors.
