TikTok API audit rejected: reason 40

TikTok's Developer Guidelines describe the categories of behavior that get an app rejected or removed — fake or incomplete submission data, unreliable performance, requesting scopes you do not use, and failing to respond to TikTok's correspondence — but they do not enumerate a numbered list of rejection reasons. Rejection emails reportedly include an internal reason identifier, but TikTok has not published what each number maps to, and we did not find a credible developer report that reliably decodes "40" specifically. If your rejection email includes free-text explanation alongside the number, that text is the more reliable signal — read it literally rather than searching for what the number means.

Audit reviewers use your app the way a real creator would: the OAuth consent screen, the scopes you request, the composer UI built from creator_info/query, and what happens after the creator hits publish. They are checking that your app's actual behavior — not your written description of it — matches what you told TikTok you would do with the permission you requested, most commonly video.publish. See TikTok API Audit Requirements for the full breakdown of what changes once you pass.

These are not a decoder ring for a specific numbered reason, but they are the categories TikTok's own guidelines and repeated developer reports (including public issue trackers on Content Posting API integrations) point to most often:

• Incomplete demo flow. Reviewers need to see the full path: login, the consent screen, the composer built from creator_info, and the post actually appearing. A demo that skips straight to "and then it posts" without showing the creator-facing steps in between is a common rejection trigger.
• UX guideline violations. TikTok's Content Posting API has specific required UX elements — for example, the privacy-level selector must not have a pre-selected default value; the creator has to actively choose it. Submissions that default this field, or otherwise diverge from TikTok's documented UX requirements, get rejected on that basis alone.
• Disrespecting creator settings. If creator_info/query reports a setting the creator has disabled (duet, stitch, comments, and so on) and your UI still offers it, that mismatch between what the API told you and what your UI shows is a documented rejection trigger.
• Missing approval confirmation. TikTok expects the creator to see and explicitly approve the exact caption, privacy level, and interaction settings before the post goes out — not a generic "Post" button with no confirmation of what is actually being published.
• Scope overreach. Requesting permissions your submitted demo does not actually use. Ask for only what the reviewer can see you doing.
• Unreachable or inaccurate policies. Your privacy policy and terms of service links need to load and need to accurately describe what your app does with TikTok data.

A rejection restarts a meaningful chunk of the review clock, so treat the resubmission as a full re-check rather than a quick patch:

• Re-read the rejection email's free-text explanation literally, not just the reason number.
• Re-record your demo end to end, including the parts that feel obvious to you — the login, the consent screen, and the creator explicitly approving what will be posted.
• Cross-check your composer against the current privacy-level and interaction-setting requirements in TikTok's own Content Sharing Guidelines, since these are the specific, documented rules UX-based rejections trace back to most often.
• Drop any requested scope your demo does not visibly exercise.
• If you are genuinely unsure what a specific reason code in your rejection means, ask TikTok directly through the developer support channel referenced in your rejection email rather than guessing from a public forum.

If a resubmission cycle is not something you want to run against your own launch timeline, PostGate's default TikTok integration connects your customers through PostGate's own developer app, which has already passed this audit. You get already-audited posting caps and public visibility from day one, and you can still bring your own audited app later once it has cleared review — see TikTok API Audit Requirements for how that works.
