Making an AI UGC video is the easy half. Getting it onto TikTok, Instagram or Facebook from software, rather than by downloading a file and uploading it by hand, runs into each platform's own approval process, account rules and consent screens, and those are the part most tools skip.
This page covers what each platform's developer documentation said on 2026-10-19 about posting video on a person's behalf, and what that means for any product that promises to post for you.
Posting a video for an account you own, in order
- Label the video firstAdd a visible AI-generated label to the video and use the platform's own AI label where it offers one. TikTok asks creators to label realistic AI-generated content; Meta labels content disclosed or detected as AI-generated.
- Use an account type that can publishInstagram publishing through its API is for professional accounts; a personal account cannot be posted to this way.
- Connect the account to the posting toolEach platform uses its own OAuth sign-in. You grant the tool permission to publish; you can revoke it from the platform at any time.
- Check the tool's approval statusA posting tool's app must be approved by the platform. On TikTok, content posted by an unaudited app is restricted to private viewing until the app passes TikTok's audit.
- Confirm the post where the platform requires itTikTok's Direct Post rules require the person to choose the privacy level, see a preview and explicitly agree before anything is sent.
- Watch the post's statusProcessing can take minutes. A good tool polls the platform for the post's status rather than assuming it went live.
TikTok
Audit before public posts
TikTok's Content Posting API docs say all content posted by unaudited clients is restricted to private viewing mode, and an app must pass an audit to lift that (Content Posting API, get started).
No default privacy level
Its content sharing guidelines say the person picks the privacy status from the options TikTok returns, and there should be no default value (Content sharing guidelines).
Interactions off until chosen
Comment, Duet and Stitch are not checked by default; the person turns each one on.
Commercial content disclosure
A disclosure toggle, off by default, for promotional content about your own brand or branded content for someone else; branded content cannot be private.
Explicit consent and a preview
The app shows the creator's nickname and a preview, and sends nothing to TikTok until the person explicitly agrees. That is why a tool posting to TikTok asks you to confirm each post.
Professional accounts only
Meta's content publishing guide says content can be published on Instagram professional accounts, and a Page that requires Page Publishing Authorization blocks publishing until it is completed (Instagram content publishing).
Permissions
Publishing needs the instagram_business_content_publish permission with Instagram Login, or instagram_content_publish with Facebook Login, at Advanced or Standard Access.
Reels
A Reel is published by creating a container with the REELS media type and a video URL, then publishing it.
A daily limit
There is a limit on API-published posts in a moving 24-hour window. The guide states it in two places with different numbers, so read the account's current figure from the content_publishing_limit endpoint rather than assuming one.
Pages, not personal profiles
Software posts video to a Facebook Page the person manages, through Meta's Graph API with the Page permissions a Page admin grants.
Meta's app review
Permissions beyond a developer's own test accounts go through Meta's review of the app before real Pages can be posted to.
The AI info label
Meta applies AI info to content it detects or that is disclosed as AI-generated (Meta newsroom).
What this means for any tool that says it posts for you
Ask which platforms have approved the tool, not just which ones it supports. Until TikTok's audit passes, a tool can post to TikTok only privately; until Meta has approved the permissions involved, it can post only to its own test accounts. A tool that says a channel is pending platform approval is describing this honestly.
Ask whose account the video lands on. Posting to your own connected accounts keeps the audience, the history and the ability to revoke access with you.
Ask how it handles per-post consent on TikTok. If a tool claims fully automatic TikTok posting with no confirmation, ask how it meets TikTok's requirement that the person explicitly agrees before content is sent.
Common questions
Can software post to TikTok automatically?
Only through TikTok's Content Posting API, and only publicly once the app has passed TikTok's audit. TikTok's guidelines also require the person to choose the privacy level and explicitly agree to each upload.
Can I post Reels to a personal Instagram account through an API?
No. Meta's content publishing guide covers Instagram professional accounts.
Do I have to label AI UGC videos?
TikTok asks creators to label realistic AI-generated content, Meta labels content disclosed or detected as AI-generated, and in the EU Article 50 of the AI Act applies from 2 August 2026. Labelling every AI UGC video is the simple rule.
Why does a tool say a channel is pending platform approval?
Because the platform has not yet approved that tool's app for public posting. On TikTok, unaudited apps can post only in private viewing mode.
