TikTok Webhooks
Webhooks from the TikTok for Developers platform (developers.tiktok.com) —
Login Kit, Content Posting / Video Kit, and Data Portability. These are not
TikTok Shop webhooks, which use a different portal and signature scheme — see
tiktok-shop-webhooks.
When to Use This Skill
- How do I receive TikTok webhooks?
- How do I verify the TikTok-Signature header?
- Why is my TikTok webhook signature verification failing?
- How do I handle authorization.removed, video.upload.failed, video.publish.completed, or portability.download.ready events?
- How do I reject replayed TikTok webhook deliveries?
Verification (core)
TikTok has no webhook SDK — verify manually. The TikTok-Signature header
looks like t=1633174587,s=<hex>. The signature is HMAC-SHA256(client_secret, "<t>.<raw_body>"), hex-encoded. Verify against the raw request body (don't
JSON.parse first) and reject stale timestamps to block replay.
const crypto = require('crypto');
function verifyTikTokWebhook(rawBody, header, clientSecret, toleranceSec = 300) {
if (!header || !clientSecret) return false;
const parts = Object.fromEntries(
header.split(',').map((kv) => kv.split('='))
);
const { t, s } = parts;
if (!t || !s) return false;
const age = Math.abs(Math.floor(Date.now() / 1000) - Number(t));
if (!Number.isFinite(age) || age > toleranceSec) return false;
const raw = Buffer.isBuffer(rawBody) ? rawBody.toString('utf8') : rawBody;
const expected = crypto
.createHmac('sha256', clientSecret)
.update(`.`, )
.();
{
crypto.(.(s, ), .(expected, ));
} {
;
}
}

Common Event Types
TikTok for Developers currently defines four webhook events:
| Event | Triggered When |
|---|
authorization.removed | A user deauthorizes your app (access token already revoked) |
video.upload.failed | A video uploaded via Video Kit fails to upload |
video.publish.completed | A video uploaded via Video Kit is published by the user |
portability.download.ready | Data requested via the Data Portability API is ready to download |
Watch the exact names: it is video.publish.completed (not .complete),
and there is no video.publish.failed. See
references/overview.md for payload details.
Payload Structure
Events are POSTed as JSON:
{
"client_key": "awx4...",
"event": "video.publish.completed",
"create_time": 1633174587,
"user_openid": "0f9c...",
"content": "{\"share_id\":\"video.7107...\"}"
}
content is a serialized JSON string — parse it separately after parsing
the envelope. portability.download.ready has no user_openid.
Environment Variables
TIKTOK_CLIENT_SECRET=your_app_client_secret
The webhook signing key is your app's client secret — the same secret used
for OAuth. There is no separate webhook secret.
Local Development
npx hookdeck-cli listen 3000 tiktok --path /webhooks/tiktok
Register the printed HTTPS URL as your callback URL in the TikTok developer
portal and subscribe to events.

Recommended: webhook-handler-patterns
We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. TikTok retries for up to 72h with exponential backoff and guarantees at-least-once delivery, so handlers must be idempotent. Key references (open on GitHub):
