Pagination

To fetch all reactions from a profile, use pagination:

Make an initial request without paginationToken
If hasMore is true, use the returned paginationToken in your next request
Continue until hasMore is false

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

  while (hasMore) {
    const params = new URLSearchParams({
      profileUrlOrUrn: profileUrl,
      count: '20'
    });
    if (paginationToken) {
      params.set('paginationToken', paginationToken);
    }

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

    const data = await response.json();
    allReactions.push(...data.reactions);
    paginationToken = data.paginationToken;
    hasMore = data.hasMore;
  }

  return allReactions;
}

Reaction Types

Value	LinkedIn Label	Description
`LIKE`	Like	Standard like reaction
`EMPATHY`	Love	Heart/love reaction
`ENTERTAINMENT`	Funny	Laughing face reaction
`INTEREST`	Insightful	Lightbulb/insightful reaction
`PRAISE`	Celebrate	Clapping/celebrate reaction
`APPRECIATION`	Support	Hands/support reaction

Notes

This endpoint counts as 1 request toward your monthly quota per API call, regardless of the count parameter value. Failed requests (errors) do not count against your quota.

Reactions are returned in reverse chronological order (most recent reactions first). The post object within each reaction has the same shape as items from GET /api/v1/posts, so you can reuse the same types in your client code.

Use the paginationToken to efficiently paginate through a profile’s reaction history without re-fetching already retrieved reactions.
