1. TikTok only lets the shop's main account (the owner) approve apps — team sub-accounts get “Sub-accounts are unable to authorize.”
2. If you are the owner, click Connect TikTok Shop and log in to TikTok.
3. If someone else owns the shop, click Copy link for shop owner and send it to them. When they approve, the shop is linked to your ItemIQ account.
