# Connecting TikTok

TikTok OAuth setup, video upload behavior, and known limitations.

TikTok's OAuth is straightforward, but the posting behavior has a quirk you need to know about.

## Connecting

Social Hub → Connect Accounts → TikTok → Connect. Browser opens to TikTok's OAuth page. Sign in with your TikTok account, approve permissions, browser returns to MusicLaunch.

## Important: uploads arrive as a notification in TikTok's Inbox

When you post to TikTok from the composer, the video arrives as a notification in your TikTok Inbox — not directly on your feed, and not in your Drafts folder. You then open the TikTok mobile app, tap the notification in Inbox, add any final touches (sounds, effects, captions), and post it there. A video's caption doesn't carry over, so paste it in TikTok. Create Post says this under the platforms whenever TikTok is checked.

In MusicLaunch, a TikTok post that went out reads "Sent to TikTok", not Published: it is waiting for you in the TikTok app. If TikTok was still processing it when MusicLaunch stopped checking, the result says so; if it isn't in your TikTok Inbox a few minutes later, check that TikTok on your phone is signed in to the account shown in Connect Accounts, then post it again. If TikTok refuses an upload, the post is marked Failed with TikTok's reason.

MusicLaunch connects through TikTok's upload option rather than direct publishing, which needs a separate TikTok approval that MusicLaunch doesn't have. The upside: you review every post in the TikTok app's editor before it goes live.

## Photo posts

Photo posts work the same way. The image is placed at a temporary public link (deleted automatically within about two days) so TikTok can fetch it, and arrives in your TikTok Inbox as a photo post, with your caption, for you to finish and publish in the TikTok app.

TikTok shows posts full screen at 9:16 (tall). With TikTok checked, Create Post shows the photo or video TikTok gets on a 9:16 phone screen; a file of another shape shows with black bars, the way TikTok shows it. A video over 200 MB is too big to preview there; TikTok still gets the whole file. For full screen, record with Take a Video at 9:16, or use a 9:16 photo such as 1080×1920.

> Because you finish every upload in TikTok, the audience (public, friends, or only you) is whatever you pick in the TikTok app's editor when you publish it — MusicLaunch doesn't set it.
