The Business app rows come from TikTok's video.insights. It is granted to every account connected through the TikTok for Business app (connection lanes).

TikTok fills them at T+24-48h and only for posts active in the last 7 days. A fresh post reports zeros and empty maps until then.

The same fields come back per day from the post timeline.

Accounts still on the developer app report likes, comments, shares and views only. Reconnecting moves the account to the Business app.

Not exposed by any TikTok API: account-level impressions and reach.

const { data: analytics } = await zernio.analytics.getAnalytics({
  query: { platform: 'tiktok', fromDate: '2026-08-01', toDate: '2026-08-31' }
});

console.log(analytics.posts);

Response (200), one entry per post:

{
  "posts": [
    {
      "_id": "65f1c0a9e2b5af0012ab34cd",
      "platform": "tiktok",
      "status": "published",
      "publishedAt": "2026-08-14T10:00:05Z",
      "platformPostUrl": "https://www.tiktok.com/@myaccount/video/7300000000000000000",
      "analytics": {

        "comments": 28,
        "shares": 45,
        "views": 15420
      }
    }
  ]
}

Account insights adds account-level counters (follower_count, following_count, likes_count, video_count) plus followers_gained and followers_lost deltas.

Live values come from the user.info.stats scope. The historical series is joined from Zernio's daily snapshotter.

Accounts connected through TikTok's Business app also report:

profileViews: the profile views a post brought in.
completionRate: the share of viewers who watched to the end, as a number from 0 to 1.

Both land 24 to 48 hours after publishing. TikTok reports completion only for posts active in the last 7 days.

Account-level impressions and reach are not available on any public TikTok API.

TikTok's Research API does not expose them either. It is restricted to non-commercial academic use under TikTok's eligibility policy.
