Imported orders from eBay: adding new SKUs breaks eBay marketplace updates

[anonbear]

Hello all,

We are currently importing orders from eBay Amazon WooCommerce Walmart into ShipStation.

For most orders, after they are imported into ShipStation, we have to add new SKUs inside ShipStation.

For example a new order gets imported into ShipStation from eBay, and then we manually open the order in ShipStation and add a new additional SKU and then we process the order.

In this case, ShipStation will no longer be able to update the eBay order with tracking number (Notify marketplace call fails) - so the only option is to manually enter the tracking numbers 1 by 1 in eBay.

There are no issues with Amazon Walmart or Woocommerce as this action does not cause any issues for those channels.

I spent alot of time with ShipStation Support Team and it was very difficult to get any help but we were finally told that this is a limitation and there are no solutions for eBay when a SKU is added to the order (marketplace will no longer be able to update with track #).

Does anyone have any work arounds for this issue? TIA

Hello @anonbear!

First, welcome to the Community! We’re so glad you’re here. This space is a great resource for finding answers, sharing feedback, and suggesting new product features—we hope you find it both helpful and inspiring!

Regarding the issue you’re experiencing, I can see that you were previously working with our Support Team, which was absolutely the right step. In ticket 9003968, Support shared the following:

“This appears to be a limitation on eBay’s side. eBay expects the SKUs (or lack of SKUs) in our ShipNotify request to match exactly what was included in the original order feed sent to ShipStation. To ensure your ShipNotify requests are accepted by eBay, please avoid modifying order items or changing SKUs within ShipStation.”

Before they can escalate this further, Support requested that you complete the following steps:

1. Create a test order on eBay
2. Import it into ShipStation
3. Make no changes to the items or SKUs
4. Ship the order typically (or mark it as shipped)
5. Confirm whether the same ShipNotify error occurs

They also outlined two potential alternatives to help your workflow:

Updating your SKUs directly in eBay

Using Alias SKUs within ShipStation

If you haven’t had a chance to run through that test yet, completing those steps will give Support what they need to continue investigating. And of course, if you have any questions along the way, we’re here to help!

I will monitor that ticket and communicate any resolution provided so the rest of the Community can stay informed.

Happy Shipping and Holidays!
