Publishing to TikTok
Video and photo posts, per-post settings, and TikTok's own limits.
Post shapes
- Video: one MP4, MOV, or WebM
- Photo post: a carousel of up to 35 JPEG, PNG, or WebP images
Limits
| Limit | Value |
|---|---|
| Caption | 2,200 characters, hashtags appended |
| Title | Up to 150 characters (from the post title, or the start of the caption) |
| Video size | Up to 4 GB |
| Video length | Up to 10 minutes, but your creator account's own ceiling governs (TikTok grants 3, 5, or 10 minutes per account), and FoPost reads it before publishing |
| Image size | 20 MB each |
| Links | Not supported in posts |
Per-post settings
The settings TikTok requires a posting tool to expose:
- Privacy: who can view the post
- Allow comments, and for video allow Duet and allow Stitch
- AI-generated content label
- Commercial content disclosure: your brand, branded content, or both
TikTok's guardrails
TikTok enforces its own posting pace. Too many posts in a day, or too many still processing, and TikTok refuses with a clear reason; FoPost backs off and the post retries rather than dying. If a video's format is refused, TikTok wants MP4 or MOV with H.264, 3 seconds to 10 minutes.
Deleting
TikTok's posting API cannot delete. Remove the post in the TikTok app; FoPost keeps its record either way.
