Amazon sales channel stopped sending shipping info back to Amazon

Shopify Discussion

Topic summary

Starting July 5th, Shopify’s Amazon sales channel stopped transmitting fulfillment and tracking information back to Amazon, affecting hundreds of sellers with thousands of orders.

Core Issues:

  • Fulfilled orders in Shopify not updating to Amazon as shipped
  • Tracking numbers not syncing, causing late shipment penalties
  • New inventory listings failing to publish to Amazon
  • Inventory quantity syncs also affected, creating overselling risks

Impact on Sellers:

  • Late Shipment Rate (LSR) violations reaching 27%+ despite on-time shipping
  • Risk of account suspension and deactivation threats
  • Dramatic sales drops (up to 95% reported)
  • Manual workarounds requiring hours daily to copy/paste tracking data

Root Cause:

  • Amazon reportedly changed API requirements in February; Shopify failed to update
  • Both companies blaming each other when contacted for support
  • Shopify provided no timeline for fixes, suggesting paid third-party apps instead

Temporary Solutions Used:

  • Manual tracking entry via Amazon’s bulk upload spreadsheet
  • Shipping directly through Amazon to keep data on one platform
  • Using apps like Matrixify to export tracking data

Resolution:

  • Issue fixed after approximately one week (mid-July)
  • However, LSR damage persists as Amazon refuses to adjust metrics retroactively

Future Concern:
Shopify announced discontinuation of the Amazon sales channel effective September 20-27, 2021, requiring migration to paid partner apps ($600-800/year). Sellers exploring alternatives like Amazon Integration Plus ($20/month), Sellbright, and other multi-channel solutions.

I received this from Shopify support. Thought I would share for possible interim solutions.

I received a response from our tech team. They said the following:

““Our Amazon channel is experiencing a few technical issues and we aren’t able to provide a timeframe for resolution at the moment. Given the importance of this integration, I’d recommend looking at some of our apps supported by third party developers. Our partners have teams dedicated to working with Amazon’s updates, so they are less likely to run into similar issues”. We are currently working with few partners on new Amazon sales channels and we would be happy to offer you early access. You can find these partners here:
