Solving the TikTok Shop & Shopify Connection Stall: A Community Deep Dive into Error 1105

Hey everyone,

As a Shopify expert and someone who spends a lot of time sifting through our amazing community forums, I often see recurring themes. One of the most frustrating, hands down, is when a vital app just won't connect. It's like your digital storefront has a stubborn door, and no matter how many times you jiggle the key, it just won't open. Recently, a thread popped up that perfectly illustrates this pain point, and it's all about connecting TikTok Shop to Shopify.

The Frustration of the '3/8 Stall'

Our story starts with a store owner, NestHomeMarket, who was at their wit's end. They were trying to link their TikTok Shop to their Shopify store, nesthomemarket.com, but the connection process kept stalling out at '3/8 completed'. Can you imagine? They tried everything: uninstalling and reinstalling the app over 25 times, disabling all browser extensions (both Chrome and Edge), making sure credentials were identical, and even trying in incognito mode. Each attempt met the same frustrating wall.

Initially, another community member, vicky32, chimed in, mentioning their own smooth connection experience and suggesting it might just be a 'glitch' and to keep trying. While persistence is often key in tech, NestHomeMarket's extensive efforts clearly showed this was more than just a fleeting hiccup. This wasn't a simple 'try again later' situation.

Uncovering the Real Culprit: The 'Error 1105'

This is where the thread got really interesting and where the true problem surfaced. After some back and forth, NestHomeMarket shared the specific error message they were getting at the start of the connection attempt. This is crucial, folks, because a vague 'it's not working' doesn't help anyone. The detailed error message was:

“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”

Now, that's a mouthful of technical jargon, but one part stands out like a neon sign: Error 1105: psm/db/finger/keyword throttled. This isn't a Shopify error; it points directly to an issue on TikTok's backend. The term 'throttled' often means that the system is limiting requests, or there's some kind of rate limit or resource constraint affecting the connection for that specific account. It's like TikTok's system is saying, 'Whoa there, slow down!' or 'Something's not quite right with this specific connection attempt from our end.'

The AI's Clue and the Support Dead End

NestHomeMarket wisely took this error message to Copilot AI, which provided a very insightful suggestion: “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.”

This is the golden nugget! It confirms the issue is on TikTok's side and suggests specific technical actions. However, here's where the frustration truly compounds. NestHomeMarket reported contacting multiple agents on seller-us.tiktok.com, only to find they “don’t have a clue what is going on.” They opened a ticket on May 2nd and, at the time of their post, still hadn't received a real answer.

What to Do When You Hit 'Error 1105' with TikTok Shop

This whole scenario highlights a critical point: sometimes the problem isn't with your Shopify settings or even the app itself, but with the backend of the platform you're trying to connect to. When you're facing a similar situation, here's my advice, drawing from NestHomeMarket's experience and what we've learned:

1. Pinpoint the Exact Error Message

Just like NestHomeMarket did, if your connection stalls, dig for the specific error message. It's your most powerful piece of evidence. Don't just say 'it's not connecting'; provide the full, unedited error.

2. Engage TikTok Seller Support with Precision

This is where you need to be persistent and precise. When you contact TikTok Seller Support, don't just ask them to fix the connection. Refer to the specific

Error 1105: psm/db/finger/keyword throttled
message. Crucially, mention what Copilot AI suggested:

  • Ask them to check and “adjust the backend flags for your account.”
  • Inquire if your “integration needs to be migrated to the new Seller Center API.”

These are specific, actionable requests that should guide them to the right technical team, rather than a general support agent who might not understand the underlying issue.

3. Document Everything and Escalate

  • Keep a detailed log of every interaction: dates, times, agent names (if possible), ticket numbers, and screenshots of the error.
  • If the initial agents are unhelpful, politely but firmly ask for your ticket to be escalated to a technical support team or a specialist who can address API integration issues.
  • Mention the specific error and the AI's suggestions again during escalation.

4. Double-Check Your TikTok Shop Account Status

Before assuming it's a deep technical glitch, quickly verify that your TikTok Shop account itself is fully set up, verified, and has no pending issues or flags on their platform that might prevent integration. Sometimes a small detail there can block the connection.

5. Consider the 'Waiting Game' (But with Active Follow-Up)

Unfortunately, as NestHomeMarket experienced, sometimes you're left waiting. However, don't wait passively. Follow up on your ticket regularly, referencing the specific error and the technical actions you've requested. The more informed and precise you are, the better your chances of getting a resolution.

The takeaway from this community discussion is clear: while Shopify offers incredible tools, integrating with external platforms can sometimes reveal their own unique backend challenges. When you hit a wall, the community can help diagnose, but for platform-specific errors like 'Error 1105' from TikTok, you ultimately need to arm yourself with specific information and relentlessly pursue their technical support. It's not always easy, but knowing exactly what to ask for can make all the difference.
