TikTok posting API via an audited app for social media agents
Blotato's TikTok posting API publishes videos and photo posts from one request, through an app TikTok has already audited.
That audit is the part most builders discover late. Until your own app passes it, TikTok restricts what it publishes to private visibility.

What the TikTok posting API does in Blotato
POST /v2/posts with targetType tiktok takes a video or a set of images plus seven required target fields, the same privacy and disclosure settings TikTok's Content Posting API demands. Captions run to 2,200 characters. Video is up to 10 minutes and 4 GB in MP4, WebM, or MOV. Photo posts take images at a maximum resolution of 1080 pixels and 20 MB each, with an optional 90-character title and autoAddMusic.
Videos and photo carousels
One video URL publishes a video. Several image URLs publish a photo post, with imageCoverIndex choosing the cover.
Drafts and cover frames
isDraft saves to TikTok drafts instead of publishing. videoCoverTimestamp picks the cover frame in milliseconds.
Analytics on published videos
GET /analytics ranks your TikTok posts by views, reach, likes, or comments, and GET /posts/:id/analytics returns one post over time.
Scheduling into the calendar
scheduledTime queues the post. useNextFreeSlot takes the next open TikTok slot in your calendar.
The seven fields TikTok will not publish without
privacyLevel, disabledComments, disabledDuet, disabledStitch, isBrandedContent, isYourBrand, and isAiGenerated are required on every call. TikTok requires these disclosures from any app, and Blotato passes them through rather than guessing on your behalf.
privacyLevel takes SELF_ONLY, PUBLIC_TO_EVERYONE, MUTUAL_FOLLOW_FRIENDS, or FOLLOWER_OF_CREATOR. Set isAiGenerated to true for AI-generated video, the disclosure TikTok requires.

Audited app, written-down warm-up: the TikTok case for Blotato
- The warm-up rules are written down. Blotato's rule: a TikTok account is warmed up by a human for at least four weeks before you connect it. It costs nothing if you read it first and a flagged account if you do not.
- Nine platforms, one envelope. The same request posts to Instagram, YouTube, LinkedIn, X, Facebook, Threads, Bluesky, and Pinterest once you swap targetType and the target fields.
- The app is already audited. TikTok's Content Posting API keeps unaudited apps in a mode where posts are visible only to the poster. Blotato's app passed the audit, so your posts are public from the first call.
How to post to TikTok through the API
- Connect a warmed-up TikTok account. At least four weeks of normal human use before you connect it, per the warm-up guide.
- Generate an API key. The API tab under Settings generates the key. Paid Starter begins the moment the key exists, since the trial excludes API access.
- Fetch the accountId. GET /users/me/accounts?platform=tiktok.
- POST with all seven fields and poll. Send the request above. Poll GET /posts/:postSubmissionId, and if it reads failed, the error message usually names the missing disclosure field.
An agent can send the seven fields for you: the TikTok tools are on the MCP server at https://mcp.blotato.com/mcp.
Setup per client is on the TikTok MCP server page, and the walkthrough of
posting to TikTok from Claude shows the prompt-to-post flow. A prompt like
"Post this video to TikTok, public, comments on, and mark it as AI-generated." calls the same endpoint this page documents.
TikTok posting caps and pricing
On Starter, Blotato limits you to 3 unique TikTok accounts per 24 hours at 10 posts per account. You can connect more than 3, but only 3 can receive posts in any 24-hour window. That is where the illustrative 900 uploads a month figure on the pricing page comes from, and the limit does not apply on Creator or Agency.
| TikTok limit | Value through Blotato |
|---|---|
| Blotato daily cap | Starter: 3 unique accounts, 10 posts each, per 24 hours; not applied on Creator or Agency |
| Caption | 2,200 characters |
| Video | MP4, WebM or MOV, up to 10 minutes and 4 GB, 23 to 60 fps |
| Images | maximum resolution 1,080 pixels, up to 20 MB each |
| Warm-up | 4 weeks of human use before connecting |
| Off-spec video | converted by Blotato only under 120 seconds |
TikTok publishes no per-call price for its API. What the audit takes and where going direct still makes sense is covered in the TikTok API pricing guide.
On TikTok, this API covers publishing, scheduling and analytics. Comments, DMs and DM automation are Instagram and Facebook only. Caps are listed at help.blotato.com/settings/social-accounts.
MCP tools that reach TikTok
The tool names an agent calls on the MCP server for this platform, verbatim from the server's tool list. The REST endpoint behind each one is in the API reference.
