Getting a warning when trying to sync to Tik Tok Shop

Topic summary

Main issue: Merchants receive a warning that connecting the TikTok Sales Channel will overwrite existing TikTok Shop product data, and some encounter errors when linking or relinking accounts.

Key points and limits:

  • One-to-one sync: Only one Shopify store can connect to one TikTok account via the TikTok Sales Channel.
  • Overwrite behavior: Syncing from Shopify overwrites products on TikTok; updates made on TikTok are overwritten by Shopify data.
  • Existing TikTok Shop: The app cannot link pre-existing TikTok products to matching Shopify products without overwriting TikTok data and history.

Recent developments:

  • A merchant accepted the overwrite and lost manually added TikTok products; afterward, products were disapproved due to missing weights. Fixing weights in Shopify should auto-resync; approval status and reasons show under “Status for Shop.”
  • Multiple users report connection/reconnection errors after account resets; a Loom video shows a red error during TikTok Shop setup.

Support and next steps:

  • Shopify notes the channel is managed by TikTok; use TikTok’s support portal for troubleshooting. Shopify can assist only with API-related issues.
  • One user suggests AfterShip may help map existing TikTok products without overwrite (unverified by Shopify).

Status: Ongoing, no definitive resolution. Attachments: screenshot and Loom video illustrate the errors.
