Shopify Marketplace Connect

I spent a great deal of time trying to make marketplace work with Ebay...I think it should be made clear inside marketplace that an Ebay connection only works one way from Ebay to Shopify!!! Not from Shopify to an Ebay listings, this frustrating and disappointing to say the lease!

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.

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.

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.

Die App wird damit beworben, auch für die Intgration von etsy geeignet zu sein. Für Neukunden ist jedoch nicht einmal mehr eine Verbindung zu etsy möglich., da laut Support die Unterstützung von etsy schrittweise abgebaut wird. Absolut unbrauchbar.

Slow support.
Engineers are unable to fix faulty images issues on Ebay for 1year+
Plenty of minor issues.

Terrible Customer Service - If you have an outage they don't fix it. Tried for 2 days couldnt list anything anywhere and there answer was our team is in Australia and they are sleeping.

I spent more than 10 hours try to listing the products, and then i got a bulk of errors, required field should be filled not included in the bulk listing...

Etsy does not show up as an option. Only amazon, Ebay and walmart

Worst Expierience so far. App on phone is not useable. Plenty of errors while importing products to Stores. Hard to figure out what the problem is.

Randomly killed my Etsy Store last week. Lost all my listings and Ranks on Etsy. Since 1 week they keep telling me they trying to figure out what happend and the team is working on it. Nothing happens. I did lost a lot of money to them and also had to pay 0,20$ for any new listing i had to do without them. Support takes days to answer and you get these no sense answer that they are aware of the problem and trying to help.

If you dont wanna loose everything you build up, dont use this app. At least not for Etsy...
