TikTok

Register a TikTok app with Login Kit and Direct Post, connect creators, and publish videos and photo posts with privacy, disclosure and cover options.

MagicPost posts to TikTok with the Content Posting API in Direct Post mode. You register one app in TikTok for Developers, and each creator connects their own TikTok account through it.

​

What you need

• A TikTok for Developers account.
• Your site served over HTTPS.
• For photo posts, a site that TikTok can reach from the internet, and a verified domain (see below).
• Access to Admin → Publishing → Platforms.

​

Register the app on TikTok

1. Create the app

   Create an app in TikTok for Developers and fill in its details, including links to your terms and privacy policy.

2. Get the redirect URI from MagicPost

   In MagicPost, go to Admin → Publishing → Platforms and click Add credentials on the TikTok card. Under What to register, copy the Redirect URI:

   https://your-domain.com/publishing/tiktok/callback
   
3. Add Login Kit

   In the TikTok app, add Login Kit and register the redirect URI for the web.

4. Add the Content Posting API

   Add the Content Posting API, switch on Direct Post, and add each scope listed in the table below.

5. Verify your site address

   TikTok downloads photo posts from your site. Verify the site’s address under URL properties in the app.

6. Submit the app for review

   Submit the app for review, then copy the Client key and the Client secret.

7. Store them in MagicPost

   Paste the key into Client ID and the secret into Client secret. The hint under the field reminds you that TikTok calls it Client key. Tick Available to users, click Save, then Run checks.

​

Permissions MagicPost asks for

Scope	Used for
user.info.basic	The account’s display name and picture.
user.info.stats	Follower, following, like and video counts for analytics.
video.publish	Direct posting.
video.upload	Uploading the video file.
video.list	Reading a published video’s figures for analytics.

Until TikTok audits the app, everything it posts is visible only to the account that posted it, and at most 5 accounts a day can post through it. Apply for the audit before your users rely on TikTok.

​

Connect a TikTok account

1. Open Channels

   Under Publishing in the sidebar, click Channels.

2. Add the account

   In Add a channel, click TikTok. Sign in on TikTok and approve access.

3. Confirm

   You return to Channels with one Profile channel. Its handle comes from TikTok.

At connection time MagicPost asks TikTok what the creator may currently do: which audiences are allowed, whether comments, Duet and Stitch are switched off, and the longest video allowed. The composer offers only those choices. TikTok answers again before every post and on every connection check, and MagicPost keeps the latest answer.

​

What you can publish

TikTok has two post types: Video and Photo.

Setting	Video	Photo
Media required	Yes	Yes
Text	2,200 characters, used as the title.	4,000 characters, used as the description.

Mixed media	Not allowed.	Not allowed.
First comment	No.	No.

The video length is also capped by the creator’s own limit from TikTok. The connection check shows it as Videos up to N minutes long.

Both post types show this notice in the composer, linked to TikTok’s page: By posting, you agree to TikTok’s Music Usage Confirmation.

​

​

How media is delivered

• A video is uploaded as bytes in chunks of up to 10 MB. Your site does not need to be reachable from the internet for this, and an upload that is cut short carries on from the last chunk TikTok confirmed.
• A photo post is different. TikTok downloads the pictures itself from a web address, so the address must be reachable from the internet and on a domain verified in the TikTok app. When it is not, the post fails with a message that names the address.

​

Connection check

Common errors

TikTok has not audited this app yet, so it can only post for Only me

The app is unaudited. Choose Only me under Who can view, or complete TikTok’s app audit.

TikTok limits how many people can post through this app each day

Until the audit passes, only a few accounts a day can post. The post is tried again later.

This account has reached TikTok's daily posting limit

The post is retried about an hour later and goes out once there is room again.

TikTok only pulls photos from a domain verified for this app

Verify the site under URL properties in the TikTok developer portal.

TikTok fetches photos over the internet, and the address cannot be reached

The site runs on an address only your own machine can reach, such as localhost. Photo posts need a public address.

This TikTok account cannot post for that audience

TikTok no longer allows the chosen audience for this account. Pick another under Who can view.

TikTok does not allow branded content to be visible to Only me

Paid partnership needs a wider audience than Only me.

This TikTok account can post videos up to a length, and this one is longer

The creator’s own limit is shorter than the general 10 minutes. Trim the video.

TikTok could not read the file

Use an MP4 or MOV with H.264 video. TikTok takes videos between 23 and 60 frames per second, and pictures between 360 and 4096 pixels on each side.

TikTok flagged the caption

Edit the caption and try again.

TikTok access was removed for this app

TikTok no longer accepts the connection. Reconnect the channel from Channels.
