TikTok Research API: Query Commercial Content
TikTok’s developer documentation describes a Research API POST endpoint (POST /v2/research/adlib/commercial_content/query/) that lets authorized clients query commercial or sponsored content metadata. Calls require an OAuth Bearer client access token and the research.adlib.basic scope, a comma-separated fields query parameter to select returned fields, and a JSON body with filters such as content_published_date_range, creator_country_code, and creator_usernames. Pagination is supported via max_count (default 10, max 50) and an optional search_id for cached searches. Responses return data.commercial_contents (objects with id, create_date, create_timestamp, label, brand_names, creator and videos), has_more, search_id, and an error struct. The docs include request/response examples and validation rules (e.g., date ranges must be after Oct 1, 2022).
Technical documentation from a major platform (TikTok) that enables programmatic access to commercial content metadata, affecting measurement, compliance, and ad transparency workflows across the advertising ecosystem.

TikTok Content Posting API Developer Guide
TikTok’s developer documentation explains how to use the Content Posting API to post videos and photos directly to creators’ TikTok accounts. The guide lists prerequisites (registered app, Content Posting API product, Direct Post configuration, and approval for the video.publish OAuth scope), describes creator-info querying, and details video upload flows (FILE_UPLOAD or PULL_FROM_URL) with example endpoints (/v2/post/publish/video/init/, upload PUT, and status fetch). It also documents a separate photo upload endpoint (/v2/post/publish/content/init/) with required post_mode and media_type fields. The docs note that content posted by unaudited clients is restricted to private viewing until the client completes an audit and that both app- and user-level authorization are required to publish.
