Tiktok Shop does not connect to Shopify. Stalls at 3/8

At the beginning, when try to Connect, there was this error message: “rpc call error, underlying err: RPCError{PSM:[ad.platform.commerce_partner_gw] Method:[MakeHTTPCall] ErrType:[RPC_FAILED] OriginalErr:[remote or network error[remote]: biz error: Error 1105: psm/db/finger/keyword throttled] BizStatusCode:[0] BizStatusMessage:} copy log info”

According to Copilot AI “To resolve this, I will need to reach out to TikTok Seller Support so their technical team can adjust the backend flags for your account or migrate your integration to the new Seller Center API.” I have contacted many agents on seller-us.tiktok.com but they don’t have a clue what is going on, so I opened a ticket and since May 2 I haven’t get a real answer on how to install TiKtoK Shop in Shopify. If anyone in this community could point me in the right direction, I would be greatly appreciated.

Can you share the link to your stor, so we can see how this affect it

My Shopify store is nesthomemarket.com

I have had my tiktok shop linked with my shopify store..it was easy. i don’t see reason why it shouldn’t connect, i’d suggest you keep trying, it might just be a glitch

I have tried more than 25 times, uninstalling it and reinstalling it, disabling all chrome and edge extensions. credentials for both are set the same. done it in incognito mode, and always the same, stalls at 3/8 completed.

I finally, after 6 weeks of making posts at business tiktok com and seller-us.tiktok.com and chatting with many TikTok Shop agents, I could connect the TikTok Shop app to the Shopify Store. It finally went to 8/8, and now I have to connect it to an add.tiktok.com account that I created, and that is still pending. The main issue has been solved; I get the Shopify products synced with the TikTok Shop.

Hi @NestHomeMarket,

That specific “Error 1105 throttled” message means TikTok’s automated security system temporarily blocked your connection attempt, usually because it flagged your browser fingerprint, IP address, or too many connection attempts at once.

Since waiting on support is taking forever, your best immediate workaround is to uninstall the TikTok app from Shopify, wait a full 24 hours to let the throttle limit reset, and then try connecting again using a completely fresh incognito window or a different device and Wi-Fi network. If it still fails and you have to reply to your TikTok ticket, explicitly ask them to escalate it to their “API Integration Engineering” team because this is an RPC server-side block, which regular front-line agents do not have the clearance to fix. Hang in there!

First, which app are you using to connect, the official TikTok sales channel, the TikTok Shop app, or a third party one? That alone can cause the stall at 3/8. The error itself, throttled and finger, means TikTok’s security system has temporarily locked your IP or fingerprint after too many attempts, so the 25 plus retries are likely keeping you stuck.

Hi @NestHomeMarket .
Doing well, I hope.

This issue is on the TikTok site, not Shopify’s.
That’s their reason support can not fix it.

Try these alternatives instantly;

Post in the TikTok shop seller forum
Disconnect and reconnect the TikTok in your Shopify admin.
This sometimes fixes it.
Since it’s been stuck for a while,
then ask them to send your ticket to the technical team.

The issue has been resolved, thanks for your advice

Glad that helps,
