Publishing to TikTok

Post shapes

• Video: one MP4, MOV, or WebM
• Photo post: a carousel of up to 35 JPEG, PNG, or WebP images

Limits

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

Creator limits

Several posting switches are set on the TikTok account itself, not in FoPost: whether comments, Duet and Stitch are allowed, which privacy levels are open, and how long a video the account may post. The composer reads them and disables anything TikTok has turned off, rather than offering a toggle that will be refused.

curl https://api.fopost.com/v1/accounts/{account_id}/tiktok/creator-info \
  -H "X-API-Key: $FOPOST_API_KEY"

Change any of them in the TikTok app and the composer picks it up on the next load.

Music and places

The composer searches TikTok's Commercial Music Library and TikTok's places, and stores the picked track and place on the post as music_id and location_id.

curl "https://api.fopost.com/v1/accounts/{account_id}/tiktok/music?q=sunrise" \
  -H "X-API-Key: $FOPOST_API_KEY"

curl "https://api.fopost.com/v1/accounts/{account_id}/tiktok/locations?q=blue%20bottle" \
  -H "X-API-Key: $FOPOST_API_KEY"

Both searches run on TikTok's Business API, behind its Marketing API product. Until that product is granted to the app, they answer 403 naming what to enable rather than an empty list that would read as no matches.

Repurposing a TikTok video

Resolve a share link to one of the connected account's own videos and hand the result to repurposing.

curl -X POST https://api.fopost.com/v1/accounts/{account_id}/tiktok/video-download \
  -H "X-API-Key: $FOPOST_API_KEY" -H "Content-Type: application/json" \
  -d '{"url": "https://www.tiktok.com/@you/video/7300000000000000000"}'

TikTok serves no raw media file, so download_url is the share address, which is what the transcript step reads. A link to a video the connection does not own answers 404, and a vm.tiktok.com short link carries no id, so open it once and pass the full link.

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.
