Shopify Marketplace Connect

The app simply does not work anymore. Since their latest update none of my listings from shopify can be listed on Amazon. None of the settings or mapped fields have changed. Just an endless list of error codes. I have contacted support who suggest I manually import all my listings on seller central which is exactly what I am trying to avoid. They admit that the app won't upload products, say they are working on it but cannot give any timescale for a solution. The support staff are very helpful, although that doesn't do much good if the product doesn't work.

The most annoying thing is it worked perfectly before the 'update'

After a call with support I was assured daily updates, unsurprisingly that hasn't materialised and I am left chasing for any update at all.

In short the support staff are great, the product seems to be useless

The app worked really well for us initially, but we ran into a major issue when all of our Etsy listings were suddenly deactivated without warning. It took four days of back-and-forth with support to finally be told it was due to a SKU-to-Etsy ID mapping issue — something we had never changed or touched ourselves.

While the support team were polite and tried to help, the issue should have been escalated much sooner. We lost valuable time and sales while waiting for a proper explanation. In the end, we had to uninstall and reinstall the app just to get our listings live again.

This experience was frustrating and stressful, especially for a small business relying on consistent visibility. If you're using the app, keep an eye on your listings and be aware that any sudden change might be related to hidden mapping settings or renewal of the app. A quicker response and clearer guidance would have made a big difference.

Support is just awful. Since they were acquired by Shopify they blame everything on Shopify and close the case while acting rude. Then you have to reach out to Shopify support who are friendly and helpful, and confirm that it's a Marketplace Connect problem. Then you have to reach back out to MC with a case number from Shopify before they'll do anything.

Marketplace Connect has a lot of bugs and is lacking in a lot of really basic features. Doesn't feel like the engineers really know how their customers are using the tool. We pay almost $100/mo in charges yet it has less features than alternatives like Veeqo which is free. In fact, Veeqo will offer 5% back on any shipping labels purchased, and can predict how many units you need to re-order based on previous sales.

I just can't understand why anyone would still use this app when the Marketplace Connect team cares so little about it themselves.

As others have noted in their reviews, this app's functionality has significantly declined since Shopify acquired Codisto. The app overrides your existing eBay or Etsy data, which can damage your store and even lead to policy violations that may result in a suspension.

The support and development teams work closely together in the same office, yet they present themselves as if they operate from multiple locations and departments. This creates a false impression that resolving issues will take a long time.

The support team consistently refuses to acknowledge problems with their application, instead blaming platforms like Etsy, Amazon, or eBay for any issues. We also use other apps without experiencing problems, which we find depend on our clients’ preferences and budgets.

Lastly, I would advise caution when believing everything they say. There are online threads that highlight deceptive tactics they use to discourage users from uninstalling the app or leaving negative reviews.

didnt work for my listings as they were customized. I did say that in the beginning and was assured it would work. Then when i linked the listings it erased data from my etsy store, I had to remove the app and now my etsy listings are not allowing me to edit them. extremely disappointed, and potentially ruined my etsy store.

After the first sync on tracking number failed, you can't re-sync. And there fore you lose that order and penalty on you.

Support is very bad and not willing to solve the problem. They only advise to change tracking and fulfill again, which I did. But they can't do anything about it.

A very bad app and support, be aware

What's the point of this app if you own a store in Canada?

Link it with Wal-Mart, Target, Ebay, Amazon, etc. in Canada!

Nope, the services available on this crappy app are not available in Canada, and they have no time frame for that availability.

Now you'll need search around on the craptacular app store to find an app that will give you the ability to sell on these platforms, forcing you to pay a middleman that literally just stands there opening and closing a gate.

Thanks Shopify! you truly are the worst.

Update 1/24/25: I wish i could go negative stars, I have reached back out and now we are supposed to re add items that their team has removed in the file. To me they have no idea what they are talking about as we are just running in circles at this point. Each day is a new person that does not read the issues and we have to explain the issue again. At this point they are throwing crap on the wall to see if it sticks. I would stay for away from this app.

Original: By far the worst app i have used. it's a 50/50 shot of even getting it to load. Filled with errors. 5+ hours with support and still at square one with them only saying "Walmart API Issues" Does not seem to have the accontability that needs to be there for a successful app. I would take positive reviews with a grain of salt and explore even paid options that might work better.

Be Aware of malicious activities. they gained access to our account and changed product prices causing us to sell a lot of units at a very low price, which had a negative profit, and we lost money. They also tried to change our bank account details to steal our money.

we reported this app to Amazon and asked to remove authorization.

if you read this review, please don't make the mistake of authorizing access to this app on Amazon, it was the worst decision we made. We could have lost complete access to our Amazon account. fortunately, only lost a few products instead of the whole account.

Not worth it. The amount of time I spend talking with support because it's so buggy fully negates the benefits. I wish I'd just set each marketplace up seperately for all the issues that would have given me than using this terrible app.
