Shopify Marketplace Connect

Marketplace Connect (Codisto) is a system that I am happy to review and give 5 stars to - but what I will say is that this could have EASILY been a 1 star.

Here's the thing, if you use the system with existing listings like I did, you are almost certainly going to have the odd issue that makes no sense. You are also going to tear your hair out trying to fix it.

But that’s where support comes in. Live chat is one of the best I have dealt with. Mark L (who I was very grumpy with to start), Mark M, and today Michael have been outstanding. Nothing is too much trouble, nothing is a silly question, and I can’t fault the support.

So here is my review. If everything works great out of the box, that's brilliant - but if you need help, then just ask.

You will NOT be disappointed.

Using PIMs across my career, it is nice to have a native app in Shopify that provides you with similar control of your products and how they display on top online Marketplaces. Easy setup, Marketplace syndication, and activation.

We are experiencing a critical issue with Shopify Marketplace Connect where inventory synchronization between Shopify and eBay is not functioning reliably.

Despite multiple support requests over an extended period, we have not received a resolution timeline or effective mitigation. This creates a significant risk of overselling and directly impacts our marketplace performance and seller account health.

For a core infrastructure connector, we expect a higher level of reliability and transparent communication regarding critical production issues.

We reinstalled this app in April 2026 having previously used it in 2019. Upon reinstallation the app merged our new eBay account with our defunct 2019 legacy account and published our entire product catalogue of 1,000+ products to eBay without our authorisation, including brands we are not licensed to sell on eBay, putting our seller account at risk of suspension. We had to manually emergency-end all listings ourselves.

Three weeks later, after dealing with multiple support agents who repeatedly suggested the same failed fixes, the legacy account data is still present in their system. We have also discovered that a former employee who left our business in 2020 still has active credentials stored within the app, representing a serious data security risk.

We have now been forced to file a formal complaint with the ICO regarding the unlawful retention of personal data.

The app itself may work well for new users, but if you have any history with it under a previous account or trading name, be warned that your old data is never deleted and can cause serious problems when you return.

We would not recommend this app to any business until their data retention and account management processes are significantly improved.

Die App bildet die Anbinund von Amazon via Shopify ab.

Es ist keine "leichte" Software , wenn man einmal den Bogen raushaut läuft alles.

Der Kundenservice , gerade "Aldrian" ist beeindruckend gut.

App comoda ed efficace. La utilizzo per collegare Shopify a Ebay

Numerous issues arose a month ago using with eBay and haven't been fixed and with no timeframe.

Patient and very helpful. I received great help today!

This ap has just randomly stopped working with no word from the developer. What used to be an awesome ap has turned into a nightmare.

Die App funktioniert leider wohl nur bei kleinen Sortimenten. Die Synchronisation der bestehenden Ebay-Listings konnte bei mir trotz Eskalation des Support Tickets an die Entwicklerabteilung nicht durchgeführt werden. Ich habe 18 Tage auf eine Lösung gewartet.
