TikTok is no longer just an entertainment platform. It has become a core ecosystem that connects content, brands, and commerce.
According to data cited by multiple third-party analytics firms, TikTok users now spend over 90 minutes per day on the app on average across several overseas markets (DataReportal, Sensor Tower, 2024). In many regions, TikTok plays a direct role in how users discover brands, evaluate products, and make purchase decisions.

What is the TikTok API?

What types of official TikTok APIs are available?
-
How do you apply for a TikTok API key?
-
How can SaleSmartly enhance TikTok operations without custom development?
What Is the TikTok API?
The TikTok API is a set of official programming interfaces provided by TikTok for developers and businesses. With user authorization and policy compliance, third-party systems can:
-
Access TikTok account, content, data, or commercial features
-
Connect TikTok user interactions with internal business systems
-
Build deeper customer journeys and operational workflows
With TikTok APIs, businesses can read public data and trigger platform actions such as content publishing or sharing. This turns TikTok from a standalone traffic pool into an integrated growth channel within a broader marketing system.
In short, TikTok APIs allow TikTok to function as a core node in a company’s digital operations rather than just a source of views.
What Types of TikTok APIs Are Available?
TikTok offers several APIs designed for different business and development needs. Below is a practical breakdown.
1. TikTok Login Kit
The TikTok Login Kit is a secure authentication system. It reduces friction during sign-up and provides a unified authorization layer for other APIs.
Key Capabilities
-
One-click login using a TikTok account
-
Fewer registration steps, higher conversion rates
-
Access to public profile data after user consent
Business Use Case
Apps and platforms that want fast access to TikTok’s global user base often use Login Kit.
For example, an eCommerce app can enable one-tap TikTok login, then personalize product recommendations based on user interests, improving engagement and conversion.
2. TikTok Share Kit
The Share Kit improves content distribution by allowing seamless sharing from third-party apps to TikTok.
Key Capabilities
-
One-click sharing of videos or images to TikTok
-
Redirects users to TikTok’s editor for effects, music, and hashtags
Business Use Case
Brands can encourage user-generated content. By pre-filling brand hashtags, each share helps expand reach, attract new users, and generate organic engagement.
3. Content Posting API
The Content Posting API allows compliant publishing and management of TikTok content through external systems.
Key Capabilities
-
Upload content directly from the web or apps
-
Sync content across platforms
-
Continue editing before final publishing on TikTok
Business Use Case
Marketing teams managing multiple TikTok accounts can streamline operations. This is especially useful for cross-border brands that publish content at scale.
4. Display API
The Display API allows third-party apps to show TikTok content and performance data.
Key Capabilities
-
Access public creator profiles
-
Retrieve video metrics such as views, likes, and shares
Business Use Case
Brands can analyze competitor or partner performance. These insights help optimize content strategy and ad planning with real platform data.
5. Data Portability API
Available to users in the EEA and the UK, this API allows users to transfer their data to third-party apps.
Key Capabilities
-
Secure transfer of profile and content data with user consent
Business Use Case
Used mainly by data management or content backup tools that help users migrate or manage their social data.
6. Research API
Designed for academic institutions and approved researchers.
Key Capabilities
-
Access public data for trend and content ecosystem research
-
Analyze topic diffusion and platform dynamics
Business Use Case
Used for:
-
Social research
-
Content ecosystem analysis
This API has strict requirements and a high approval threshold.
7. Commercial Content API
This API increases transparency around branded and paid content.
Key Capabilities
Public access to:
-
Paid ad data such as launch dates, targeting info, and reach
-
Advertiser identity and registration country
-
Commercial video links and performance metrics
Business Use Case
Brands can analyze industry ad trends.
For example, searching TikTok ads in the US between June and December 2022 using keywords like “chatbot” helps teams refine creative strategy.
8. TikTok Business API
This is TikTok’s core API for advertising and commercial operations.
Key Capabilities
-
Campaign creation and management
-
Audience segmentation and targeting
-
Webhooks for real-time updates
-
Lead generation ads and data retrieval
Business Use Case
The Business API connects ads, content exposure, and sales outcomes. It enables precise targeting and advanced performance analysis.
How to Apply for a TikTok API Key
The standard process includes:
-
-
Create an app and submit API requests
Provide use cases, system details, and privacy policies. -
Wait for TikTok review
Select required APIs and submit for approval. -
Receive API credentials
Approved apps receive API keys and secrets.
Important Notes
-
Review standards are strict, especially for Research and Data Portability APIs
-
Ongoing development and maintenance require long-term engineering resources
For this reason, TikTok APIs are not the best fit for every business.
Most companies want a simpler outcome: convert TikTok traffic into conversations and sales. In many cases, using a mature SaaS platform is more efficient and cost-effective than building API integrations from scratch.
