TikTok

Connect your TikTok account to publish videos and photo posts.

OmniSocials publishes videos and photo posts to TikTok through TikTok's official API. This article covers what you can publish, how to connect your account and the TikTok settings you choose for every post.

What you can publish

FormatDetails
Photo postUp to 35 photos, with a title and a caption. Create it with the Post type.
VideoOne video, created with the Reel type or the Post type. Duet, stitch and AI settings are only available with the Reel type.

Comments on your TikTok videos can also come into your Social Inbox once you enable comments, see below.

Requirements

  • A TikTok account.
  • The Manage social channels permission in your OmniSocials workspace.

Each workspace connects one TikTok account.

Connect TikTok

  1. Click the workspace name at the top of the sidebar, then click the channels button under the workspace. The Channels window opens.
  2. Under Add a channel, click TikTok.
  3. Sign in to TikTok and allow OmniSocials access.

Enable comments

Comments in the Social Inbox and the first comment need a second TikTok authorization.

  1. In the Channels window, click Enable comments in the connected TikTok row.
  2. Sign in to TikTok with the same account you connected for posting, and allow access.

The row then shows Comments on. If the row shows Unlock analytics permissions, click it once to allow the newer analytics permissions.

TikTok options in the editor

Click the TikTok icon in the channel bar to see and edit the TikTok version of your post. For a photo post you can add a title and a caption. A video has only a caption.

TikTok's settings are post options. The bar under the editor has chips for who can view the post (for example Public), Comments, Promotional content and, once comments are enabled, First comment. Click the arrow at the end of the bar to see all of them on TikTok's page in the options panel. See Set post options.

SettingForWhat it does
Who can viewAll postsPublic, Friends, Followers or Private. The choices depend on your TikTok account. Required.
Allow commentsAll postsLets people comment
Add music automaticallyPhoto postsLets TikTok pick a soundtrack. Off by default.
Allow duetsVideos (Reel type)Lets people make duets with your video
Allow stitchesVideos (Reel type)Lets people stitch your video
AI-generated contentVideos (Reel type)Marks the video as made with AI
Promotional contentAll postsMarks the post as promoting a brand, a product or a service. Then, under This post promotes, turn on Your brand, Branded content (another brand) or both. With Branded content, TikTok labels the post "Paid partnership", otherwise "Promotional content".
First commentAll postsPosted after the post goes live. Shows once comments are enabled. The video must be public and allow comments.

Under the settings, TikTok's posting declaration names the TikTok policies you agree to by posting. If comments, duets or stitches are turned off in your TikTok settings, those switches can't be turned on here.

TikTok doesn't accept a custom cover image. A TikTok video uses a frame from the video, which you choose under Thumbnail with Select from video.

Limits

Limit
Caption2,200 characters for videos, 4,000 for photo posts
Photo post title90 characters
First comment150 characters
PhotosUp to 35 per post. Photos and video can't be mixed.
Image filesJPEG, PNG or WebP, up to 20 MB
Video lengthUp to 10 minutes, or the lower limit TikTok sets for your account (3 or 5 minutes)
Video filesUp to 1 GB, the OmniSocials upload limit

When you open the TikTok version of a reel, the editor shows the maximum video length for your account.

Troubleshooting

You can't schedule the post. Choose who can view the post under Who can view in the TikTok options. If Promotional content is on, also turn on Your brand, Branded content or both.

The TikTok version says Cannot Post Right Now. Your account reached TikTok's posting limit. Try again later.

Comments don't show up in the Social Inbox. Click Enable comments in the TikTok row of the Channels window and authorize the same TikTok account. If the row says Re-enable comments, click it to renew the authorization.

The video is too long. TikTok sets the maximum length per account. Trim the video, or turn TikTok off for this post.
