Tik Tok shop disconnected from shopify app

Topic summary

Multiple Shopify merchants experienced a sudden disconnection between their TikTok Shop and Shopify integration, preventing order syncing. The error message indicated an expired access token that couldn’t be refreshed through normal means.

Initial troubleshooting attempts failed:

  • Clearing cookies and cache
  • Reinstalling the app
  • Contacting support (both TikTok and Shopify provided unhelpful responses, with each blaming the other platform)

Root cause identified:
One user discovered the issue was related to a recent Chrome browser update that blocks third-party cookies by default.

Solution:
Change Chrome settings to “always allow” third-party cookies and delete cookie data for the TikTok app.

Current status:
Most users report the connection issue resolved either through the Chrome fix or automatically on its own. However, a new problem emerged: tracking information no longer syncs from Shopify to TikTok Shop after creating shipping labels.

Temporary workaround mentioned:
Some merchants used AfterShip for TikTok Shop as an interim solution to maintain order flow during the outage.

I guess for some people it worked. For me it started working on its own, however now my tracking information does not sync from shopify to tts after creating labels.

Same here. The orders sync into shopify now, but my tracking info doesn’t sync from Shopify to tts anymore. Are you having this issue too?

It sounds like you’re encountering an issue with the access token for your TikTok shop integration, which can cause syncing errors between Shopify and TikTok. To resolve this, try re-authenticating your TikTok Shop account through the Shopify app by disconnecting and reconnecting it. If that doesn’t work, check if there are any updates for the TikTok app in Shopify, or try resetting the integration by removing and re-adding the app. If the problem persists, contacting both Shopify and TikTok support again may be necessary for further troubleshooting, as it might involve permissions or backend syncing issues.
