TikTok Hashtag reads the public videos filed under one hashtag and returns each video's caption, link, the creator's display name and handle, likes, comments, shares, views and publish time. It shows what gets posted under a campaign or challenge tag, how much engagement the tag draws and which creators lead it, which serves trend tracking, hashtag campaign reports and finding creators in a niche.

Pass the tag itself, such as fyp; it is not a free-text query, so for phrases that are not a hashtag use TikTok Search instead. Each row's `url` is a video link that TikTok Comments and Transcript accept, which lets you move from a tag to what viewers said and what the video says. Null counts mean TikTok did not disclose the number, not zero.

## Parameters

| name | type | required | default | description |
|---|---|---|---|---|
| hashtag | not declared | yes | not declared | Target hashtag name for the `hashtag` action, with or without the leading `#`. This parameter filters specifically by hashtag and does not function as an arbitrary full-text search term. |
| limit | integer (1–30) | no | 10 | The most rows to return in this call, an integer from 1 to 30. The default applies when you leave it out, and a call can return fewer rows. Larger values return 422 before any charge. |

## FAQ

### How is Hashtag different from TikTok Search?

Hashtag reads the feed of one exact tag. TikTok Search matches a keyword across public videos and can also look for accounts. Use Hashtag to report on a campaign or challenge tag, and Search when your topic is a phrase or a theme that people tag in many different ways.

### Should I include the # in `hashtag`?

Either form works: fyp and #fyp read the same tag. Pass one tag per call, spelled as it appears on TikTok, without spaces. To compare several tags, call once for each and store the tag name with its rows.

### How do I find the creators behind a tag?

Group the rows by `author_username` to see who posts most under the tag and whose videos draw the most likes and views. That handle is also the input TikTok Videos by user takes, so you can go on to read each creator's own videos.
