TikTok Publishing

This page contains high-level specifications for scheduling and publishing TikTok posts through Publisher.

If your post does not meet the requirements to publish, Publisher informs you so you can correct the post.

The TikTok API allows only 20 posts within 24 hours. This period of time starts from when the first post is published to the target account. Publisher keeps track of your publishing history and will warn you when the limit is reached.
