TikTok Minis SDK In-App Ads Documentation
TikTok's developer documentation for the Minis SDK details APIs and examples for integrating in-app monetization into mini apps on TikTok. The page documents rewarded video and interstitial ad support via TTMinis methods (e.g., TTMinis.createRewardedVideoAd and TTMinis.createInterstitialAd), the rewardedVideoAd and interstitialAd objects (methods: show, onClose, onError, offClose, offError), SDK compatibility notes (interstitials supported from SDK v0.3.0), usage examples in TypeScript, and a comprehensive list of error codes for create and show ad operations. The page is part of the broader TikTok for Developers portal covering Minis platform setup, monetization, APIs, and related SDK guides.
Provides SDK-level monetization APIs for TikTok mini apps (rewarded and interstitial ads), which affects developers and ad inventory on a major social platform but is a routine documentation update rather than an industry-shifting policy change.

The changelog targets developers building TikTok Minis and Mini Games and documents specific API names and client version mappings for each release.
TikTok Minis SDK Basic Utility Documentation
TikTok's developer documentation page describes the Minis SDK basic utility APIs and the broader developer product surface. It lists integration resources (Mobile SDKs for iOS/Android, Server APIs, Webhooks), developer kits (Login Kit, Share Kit, Display API), content and commerce APIs (Content Posting API, Commercial Content API, Monetization, Data Portability API), and Minis-specific tooling for Mini Games and Mini Dramas. The page documents core Minis utility calls: TTMinis.init (requires a clientKey and must be called before other SDK methods), TTMinis.canIUse (a granular runtime API compatibility checker), and env runtime fields (e.g., USER_DATA_PATH). The docs are published on TikTok’s Developers site and present examples, parameter definitions, and links to related guides and changelogs.
TikTok Minis SDK UI Documentation
TikTok's Developer Portal documents the Minis SDK UI APIs used by HTML-runtime mini-games and mini-apps on the TikTok platform. The page describes TTMinis methods such as getMenuButtonBoundingClientRect (returns menu button layout: width, height, top, right, bottom, left in pixels) and setNavigationBarColor (accepts frontColor and backgroundColor; callback returns is_success and error). The portal also enumerates related developer products and APIs — Mobile SDKs (iOS/Android), Server API, Webhooks, Login Kit, Share Kit, Content Posting API, Data Portability API, Display API, Research Tools, Commercial Content API, Monetization, TikTok Minis (mini-games/mini dramas) and Mini Games SDK — and links to guides, changelogs and monetization/in-app ad references.
