Post vertical videos to TikTok through the Content Posting API — direct publish or draft upload.
TikTok integration
TikTok Content Posting API integration: direct-to-feed publishing and draft uploads with caption control.
Key capabilities
- Direct publish — video posts straight to the creator's feed.
- Draft upload — send to TikTok drafts for manual finishing touches.
- Caption control — post text with hashtag support.
- Audience settings — public, friends, or private visibility.
Use cases
- Publish vertical cuts immediately after render.
- Push drafts so creators can add sounds and effects natively.
- Cross-post the same render to TikTok and YouTube Shorts.

Frequently Asked Questions
Why can I only post privately?+
Unaudited TikTok developer apps are restricted to SELF_ONLY posts until TikTok approves the app for public posting.
Video requirements?+
MP4 or WebM, 3 seconds to 10 minutes. Vertical 9:16 recommended — other ratios are letterboxed.
Can I set a thumbnail?+
TikTok auto-generates the cover frame; custom covers aren't exposed through the posting API.
Best practices
- Use draft uploads when the creator wants to add native sounds.
- Keep videos under 60 seconds for best completion rates.
- Expect unaudited apps to be limited to SELF_ONLY — plan QA accordingly.
