access_token_invalidAuthenticationTikTok rejected the access token.
- Why it happens
- TikTok tokens expire 24 hours after issue. If the refresh token is also gone or stale, the integration is bricked.
- How to fix
- Reconnect the TikTok account to mint a new token pair.
- How PostPeer handles it
- PostPeer refreshes TikTok tokens preemptively and persists the rotated refresh token immediately, since TikTok refresh tokens are single-use.
