Call the TikTok API

Publish a video to TikTok

Upload a video, then call POST /v1/posts. SocialAPI.ai validates the post against TikTok's rules before sending it and returns a normalized response once TikTok finishes publishing.

curl -X POST https://api.social-api.ai/v1/posts \
  -H "Authorization: Bearer <your-api-key>" \
  -H "Content-Type: application/json" \
  -d '{
    "targets": [{ "account_id": "<tiktok-account-id>" }],

Comparison: The official API vs one API key

Aspect	The TikTok API for Business (direct)	With SocialAPI.ai
Getting access	The TikTok API for Business (direct)Register an app on the TikTok API for Business portal and pass TikTok's access reviews for the Accounts and Mentions APIs.	With SocialAPI.aiNo application. Connect a TikTok account through OAuth on the free tier today.
Comments and mentions	The TikTok API for Business (direct)Separate endpoints per resource, a video id passed with every comment write, and errors returned as HTTP 200 with a code in the body.	With SocialAPI.aiThe same inbox endpoints and Interaction shape as Instagram and YouTube, with standard HTTP status codes.
Uploading video	The TikTok API for Business (direct)Chunked upload protocol with initialization, ranged PUTs, and status polling.	With SocialAPI.aiUpload once through the unified media endpoint; chunking and polling happen behind it.
Multi-platform	The TikTok API for Business (direct)A TikTok-only integration with its own auth, retries, and data shapes.	With SocialAPI.aiThe same POST /v1/posts call that publishes to Instagram, Threads, and LinkedIn.

In depth: How the TikTok API works on SocialAPI.ai

Publish videos and photo posts to TikTok, read and reply to the comments they get, and track the posts and comments that mention you, without registering a TikTok app or passing TikTok's access reviews. SocialAPI.ai's managed app covers you, and the same /v1/posts and inbox endpoints you use for every other platform cover TikTok.

TikTok comment management

Read every comment on your TikTok posts through the same inbox endpoint you use for Instagram and YouTube, with each comment's replies one call away. Reply to a comment, post a new top-level comment, hide or like comments, and delete your own comments. New comments also arrive at your webhook endpoint as comment.received events, so a support tool or agent can answer them as they come in.

Mention tracking and replies

Fetch the TikTok posts whose captions mention your account and the comments that mention it, merged into one list in the unified Interaction shape. Reply to a comment mention through the same reply call used for Instagram and Facebook mentions, to build brand monitoring, UGC collection, or response workflows.

No TikTok developer account required

SocialAPI.ai's managed TikTok app already holds TikTok's Accounts and Mentions permissions, covering profile, posts, comments, and mentions. Connect a TikTok account through OAuth and start publishing and replying without registering your own app or waiting on TikTok's reviews.

Video and photo publishing

Publish a video by uploading the file once, then calling POST /v1/posts, or publish a photo post of 2 to 35 JPEG or WebP images with media_type set to photo. Videos publish publicly, and photo posts take a privacy_level under platform_data.tiktok. SocialAPI.ai checks captions, image counts, formats, and privacy values before the request reaches TikTok and returns a clear error when one is off.

List published videos

Fetch a connected account's published TikTok videos through GET /v1/posts, the same endpoint used for every other platform. Posts published through SocialAPI.ai are stored immediately, and background sync also pulls in videos published natively on TikTok, including view, like, comment, and share counts.

The same endpoint as every other platform

Publishing to TikTok uses the same POST /v1/posts call, with targets and media_ids, that already publishes to Instagram, LinkedIn, and every other connected platform. TikTok-specific fields like privacy_level live under platform_data.tiktok, so the core of your integration code doesn't change per platform.

Good to know

TikTok's API does not support editing or deleting a post after it's published. PATCH and DELETE requests to /v1/posts/:pid return 501 Not Supported for TikTok targets.
Videos publish publicly: a privacy_level other than PUBLIC_TO_EVERYONE on a video is refused before the request reaches TikTok. Photo posts take a privacy_level, and the allowed values depend on the connected creator's account settings.
Mentions are available for TikTok Business Accounts. TikTok surfaces a mention 24 to 48 hours after it happens and asks integrations to pull mentions at most once a day per account.
TikTok accounts connected before October 13, 2026 keep publishing as before. Reconnect them once to enable comments, mentions, and comment webhooks; each account keeps its ID and post history.
Comment replies are limited to 1,200 characters, and TikTok has no private reply to a comment.
TikTok video posts recommend MP4 files, and the maximum duration is set per creator by TikTok rather than a fixed limit for every account.
Photo post captions are limited to 90 characters, and photo posts accept JPEG and WebP images only.

Simple, honest pricing.

Reading comments, DMs, and mentions is free and unlimited on every plan. Paid plans start at $29/mo with unlimited posts and interactions. The free tier needs no credit card.

Frequently asked questions

What developers ask before they ship TikTok.

Does TikTok have a public API?

Yes. The TikTok API for Business lets approved apps publish posts, read and reply to comments, and track mentions. Getting direct access means registering an app on TikTok's Business portal and passing TikTok's access reviews; SocialAPI.ai's managed app has already done both.

Is the TikTok API free?

TikTok does not charge for API access, but using it through your own app requires passing TikTok's access reviews first. SocialAPI.ai's managed connector skips that: start on the free tier, or move to a paid plan from $29/mo for higher volume.

Can I post videos to TikTok through an API?

Yes. POST /v1/posts publishes a video or a photo post to a connected TikTok account using pre-uploaded media IDs. SocialAPI.ai validates the post against TikTok's rules before the request reaches TikTok.

Can I read TikTok comments through the API?

Yes. List the comments on any of your TikTok posts and their replies, reply, hide or like comments, and delete your own comments through the same inbox endpoints used for every other platform. New comments also arrive as comment.received webhook events.

Can I track TikTok mentions through the API?

Yes, for TikTok Business Accounts. The mentions endpoint returns the posts and comments that mention your account in one list, and you can reply to a comment mention. TikTok surfaces a mention 24 to 48 hours after it happens.

Do I need a TikTok developer account?

No. SocialAPI.ai's managed connector already registered a TikTok app and passed TikTok's access reviews, so you connect a TikTok account through OAuth without registering or reviewing your own app.

Can AI agents post to TikTok?

Yes. The built-in MCP server exposes publishing, comments, and mentions as tools, so Claude and other MCP-capable agents can publish TikTok posts and answer comments inside your existing approval flow.
