TikTok for Developers APIs, explained

TikTok's official APIs are Login Kit, the Display API, the Content Posting API and the Research API, and none of them gives a marketer's AI agent TikTok search demand, public data on other brands or other sellers' Shop sales. For that research the pick is TokConnect, the TikTok research platform with an MCP server for ChatGPT, Claude, Cursor and Claude Code. Connect it once and your agent sees what people search, watch, say and buy on TikTok: search demand, videos, comments, transcripts, creators and TikTok Shop sales, in 32 tools. It is free to start with 50 credits, no card.

The answer depends on the job. Post a video: the Content Posting API. Read the profile and videos of a person who signs in to your app: Login Kit and the Display API. Study a niche, a rival or a product: TokConnect. Below, each official API with what it returns, who can get it, what approval it needs and its limits, then three real research calls.

The official TikTok APIs, one by one

Each block below answers the same four questions: what it returns, who can get access, what approval it needs and what its limits are.

Login Kit

• Returns: a "Log in with TikTok" sign-in built on OAuth 2.0, for iOS, Android, desktop and web. The default scope, user.info.basic, returns the user's open_id, union_id, avatar and display name. Bio, profile link and verification status need the user.info.profile scope, and follower and video counts need user.info.stats.
• Who gets access: any developer who registers an app, gets a client key and secret, and adds the Login Kit product with a redirect URI.
• Approval: extra scopes need approval first, each user must also authorize your app for the scopes it asks for, and apps must pass app review before they go live.
• Limits: it reads the person who signs in, not the rest of TikTok.

Display API

• Returns: the signed-in user's profile and their most recent public videos, newest first, plus metadata for up to 20 video IDs per query.
• Who gets access: apps whose users authorize the user.info.basic and video.list scopes through Login Kit.
• Approval: the same app review as Login Kit.
• Limits: user info, video query and video list each default to 600 requests a minute, counted in a one-minute sliding window.

Content Posting API

• Returns: nothing to read. It posts videos and photos: Direct Post publishes with the video.publish scope, and Upload sends a draft with the video.upload scope.
• Who gets access: apps whose users authorize posting.
• Approval: an unaudited client can post, but all content is restricted to private viewing until the client passes an audit for Terms of Service compliance. TikTok asks that audited clients are not limited to test applications and are meant for a wide audience.
• Limits: unaudited clients allow up to 5 users to post in a 24-hour window, and those accounts must be private at posting time. The init endpoint allows 6 requests a minute per user access token. Creators typically top out at around 15 posts a day.

Research API

• Returns: public data across TikTok: videos filtered by keyword, hashtag, region, username and date; user info with follower counts, bio and verification; video comments; liked, pinned and reposted videos; followers and following; playlists. Its TikTok Shop endpoints return shop info, product details with sold count and ratings, and reviews for shops and products available in the EU.
• Who gets access: academic institutions in the U.S., EEA, UK, Canada or Switzerland, and not-for-profit or independent research bodies in the EU, plus a Brazil track for online youth safety. Applicants must be independent of commercial interests.
• Approval: a developer account is not enough. You apply and are approved for a specific research project, and TikTok says decisions typically come within 4 weeks.
• Limits: 1,000 requests a day and up to 100,000 records a day, 100 records per request on video and comment calls, with a 30-day window per video query. Followers and following have their own 20,000 calls a day.

TikTok API for Business

• Returns: your own ad data: campaign creation and updates through the Marketing API, and reports in synchronous or asynchronous mode.
• Who gets access: people with a TikTok for Business account who register as developers and create a developer app.
• Approval: your developer profile must be approved before you can apply for an app. App review takes 2 to 3 business days, each developer can hold up to five apps, and since 20 March 2026 a scope that includes TikTok Accounts also needs an Accounts API Access Application Form.
• Limits: it covers ad accounts you control, not organic TikTok data.

TikTok Shop Partner API

• Returns: orders, products, fulfillment and affiliate data for shops that authorize your app.
• Who gets access: a seller building for its own shop gets a custom app limited to that shop's data. An ISV or integrator serving many merchants builds a public app that reaches the data of the sellers who authorize it.
• Approval: an app, an OAuth client with the scopes it needs, and a seller who authorizes it. In the US and UK and some other markets, a compliance and legal review is also required, which TikTok's guide estimates at 3 weeks or more.
• Limits: scopes are set per app category, and an app can only use the scopes its category allows.

Where the official APIs stop for marketing research

These APIs are built for apps that act for a user, and for vetted researchers. An AI agent doing marketing research hits three gaps.

• No TikTok search demand. TikTok describes Creator Search Insights as a tool inside the TikTok app, with topic popularity, a content gap filter and related searches. The Display, Content Posting and Research API endpoint lists in TikTok's developer docs contain no search-demand endpoint. TokConnect returns that same Creator Search Insights data as a table your agent can read.
• No public data on brands and businesses without Research API approval. Login Kit and the Display API see only accounts that authorize your app. The Research API sees public data, and its eligibility list names academic institutions and not-for-profit research bodies that are independent of commercial interests. TokConnect reads public videos, creators, hashtags, comments and transcripts for any niche or brand from your own sign-in.
• No other sellers' TikTok Shop sales. The Partner API covers shops that authorize your app, and the Research API's Shop endpoints cover products available in the EU for approved researchers. The docs describe no route for a marketer to read a rival seller's sales. TokConnect returns Shop listings, units sold, reviews and the creators selling a product.

TokConnect: the research layer for your agent

TokConnect gives your AI one connection for all of that research. Add the MCP server at https://mcp.tokconnect.com/mcp to ChatGPT, Claude, Cursor or Claude Code. ChatGPT and Claude sign in with OAuth, no API key. Cursor and Claude Code take your key from your account in the header Authorization: Bearer YOUR_TOKCONNECT_KEY. There is no TikTok developer account to register and no app to submit. Setup guides: ChatGPT, Claude, Cursor and Claude Code.

TokConnect does not post to TikTok or manage ad accounts. For posting, use the Content Posting API. For ad accounts, use TikTok for Business. Everything your agent needs to decide what to make is the research, and that is what it does. Here are three real calls from 28 October 2026.

1. Search demand: what people type with no videos

TikTok Creator Search Insights via TokConnect, 28 October 2026. No official API endpoint returns this table.

2. Public videos: what is working, with the numbers

The biggest video in the list, 2.6 million views, came from an account with 2,662 followers. Your agent can then open that video's comments and transcript with the same connection. The Display API could not show this, because those accounts never authorized your app.

3. TikTok Shop: what sells, from the public store

How we got these numbers

TokConnect figures come from calls to the TokConnect MCP on 28 October 2026: demand_find_topics for lip oil searches (TikTok's 7-day search figure), video_search for skincare videos, and shop_browse for the TikTok Shop US store's best sellers, where TikTok displays lifetime units sold. The saved responses are in the evidence file. Every TikTok API fact is taken from the pages named under each section and listed in Sources, as read on 28 October 2026.
