TikTok Comment Keyword Alerts: Email, Webhook & In-App

You don't want every comment. You want the three that say 'where do I buy this'. Here's how to set keyword alerts so only those reach you — instantly, on the channel you actually check.

Quick answer

On a tracked TikTok video, open the comment alert keywords box, type a word and press Enter to chip it (paste several separated by commas or spaces), then enable a channel in alert settings. Any new comment that matches — built-in buyer phrases plus your own — fires an alert with the keyword, the comment, and the commenter's handle.

A comment section that's doing numbers is mostly noise: emojis, tags, side conversations. Buried in it are the comments that matter to the business — the ones asking how to buy, where to get it, whether it ships. Keyword alerts are how you pull just those out, in real time, without reading the whole thread.

The two kinds of keywords

  • Built-in purchase-intent — phrases like "where to buy", "link", "price", "discount code", and "app" are always scanned, on every tracked video, with no setup.
  • Your custom keywords — product names, your brand, a campaign code, "ship to", a competitor's name. Add them per video; they run on top of the built-ins.

Adding keywords

  1. 1
    Open the keyword box
    On the tracked video's detail page, find comment alert keywords.
  2. 2
    Type and Enter — or paste a batch
    Type a word and press Enter and it chips instantly, like any tag input. Adding several? Paste them comma- or space-separated and they all chip at once.
  3. 3
    Done — it's saved
    Keywords persist on the video and the scanner uses them on the next comment refresh. Remove one by clicking its ×.

Choosing channels

Keyword alerts ride the same delivery system as the rest of KOLens' alerts, so you configure them once in alert settings:

  • Email — the full alert rendered inline, including who commented.
  • Webhook — stable JSON for Slack, Discord, Zapier, or your own endpoint; the one to wire into automation.
  • DingTalk — for teams that live there.
  • In-app feed — always on at /alerts, with keyword chips, the quoted comment, and a one-click link to message the commenter.

A shared per-hour rate limit spans the channels, so a comment section that suddenly catches fire can't nuke your inbox.

Why the signal stays clean

Each comment is scanned for keywords exactly once — when it's first captured. Later re-scrapes refresh like and reply counts but never re-fire an alert for a comment you've already seen. The result is an alert stream that's a list of genuinely new, genuinely relevant comments, not a re-notification treadmill.

The payoff

The highest-value use of this is comment-to-DM — catching a buyer-intent comment and messaging that person while intent is hot. For the delivery internals, see email + webhook delivery.

Frequently asked

How do I add custom comment keywords on TikTok?
On a tracked video's detail page, open the comment alert keywords box, type your keywords, and press Enter — each becomes a chip instantly. You can paste several at once separated by commas or spaces ('where to buy, discount code, ship to UK'). The built-in purchase-intent set runs alongside whatever you add, so you don't have to re-enter the obvious buyer phrases.
What's in a comment keyword alert?
Four things: the keyword(s) the comment matched, the comment text itself, the commenter's @handle (so you know who to reply to or DM), and a link to the tracked video. The email renders all of it inline; the webhook delivers it as stable JSON; the in-app feed shows the keyword chips, the quoted comment, and a one-click 'message them' link to the commenter's profile.
Which notification channels are supported?
Email, a generic webhook (Slack, Discord, Zapier, or your own endpoint), DingTalk, and the always-on in-app /alerts feed. You control which are active in alert settings, and a shared per-hour rate limit keeps a busy comment section from flooding every channel at once.
Will I get re-notified about the same comment?
No. Each comment is scanned for keywords exactly once, when it's first seen. Subsequent re-scrapes of the video update existing comments' like/reply counts but never re-fire an alert for a comment you've already been told about, so the alert stream stays a clean list of genuinely new matches.
