TikTok

Publish video to TikTok from a URL. We call the Content Posting API's init endpoint, pull your file, and track the publish status — you send a caption and a link.

Connect TikTok

TikTok connects over OAuth. Complete the network’s OAuth to mint an access token, then connect TikTok from the dashboard’s Accounts page. These are the fields it needs:

FieldSend asRequiredWhere to find it
Access tokensecretaccessTokenRequiredvideo.publish scope

Everything marked secret is sealed with AES-256-GCM before storage — see Connecting accounts.

Publish to TikTok

Once connected, TikTok is just another id in your platforms array. One call publishes:

curl https://postmyish.com/api/v1/posts \
  -H "Authorization: Bearer $POSTMYISH_KEY" \
  -H "Content-Type: application/json" \
  -d '{"caption":"wait for it… 👀 #buildinpublic","platforms":["tiktok"]}'

The same request can fan out to Instagram, YouTube and more — add their ids to the array. See Publish everywhere at once.

What you can do

  • Video from a URL. PULL_FROM_URL — TikTok fetches the file you host; no multipart upload.
  • Captions to 2,200. Title/caption with hashtags, delivered with the post.
  • Status tracking. We keep the publish_id and can poll delivery status.
  • Fan-out. The same call lands on Instagram and YouTube too.

Setup & review

The Content Posting API requires an app audit before public posting. Until it clears, posts go out private (SELF_ONLY) to the creator — we set that automatically so nothing posts publicly by accident.

FAQ

Is this the official TikTok API?

Yes — the TikTok Content Posting API with the video.publish scope.

Can I post publicly?

Direct public posting unlocks after TikTok's app audit. Before that, the API only allows private (SELF_ONLY) posts to the creator's own account — a TikTok rule, not ours.

How is the video sent?

Via PULL_FROM_URL: you host the file and pass its URL as media; TikTok fetches it. Hosting uploaded files is the one prerequisite.

Can I schedule?

Yes — schedule_at queues it and we run the init/upload/poll flow when it fires.
