How this service works
Instant, low-cost Amazon, Walmart, Shopify, and eBay listing, upload-preparation, advertising, and image-brief deliverables.
Output
Returns a job ID and queued status immediately upon submission; the completed analysis identifies the specific root cause(s) of the FBA inbound shipment issue (e.g. receiving errors, labeling problems, quantity mismatches), along with diagnostic details and recommended resolution steps to help the seller address or dispute the issue with Amazon.
Example use cases
Diagnosing FBA quantity discrepancy
“Amazon says they received 80 units but I shipped 100 — can you run a root cause analysis on my FBA inbound shipment to figure out what caused the discrepancy and what I should do next?”
Investigating rejected FBA shipment
“My FBA inbound shipment got rejected at the Amazon fulfillment center — can you analyze what the root cause was so I know whether it was a labeling issue, a packing issue, or something else?”
Building a dispute case for Amazon
“I need to build a case to dispute a short-receive on my FBA shipment — can you run the inbound root cause analysis so I have a documented explanation of what happened to submit to Seller Support?”

POSThttps://friday-seller-tools-production.up.railway.app/v1/amazon/fba/inbound-root-cause?utm_source=zero.xyzWhen to prefer
Choose this endpoint when a seller needs to diagnose why an Amazon FBA inbound shipment was flagged, short-received, rejected, or shows inventory discrepancies — especially when preparing to file a dispute or corrective action with Amazon Seller Support. It is purpose-built for FBA inbound logistics troubleshooting rather than general listing creation or advertising tasks.

- Shipment data not yet available in Amazon's system returns a not-found error
