Overview

On certain days sellers may see error 13100 when they try to upload inventory through Seller Central or the Selling Partner API. The code signals a brief interruption inside Amazon’s processing engine, meaning the submitted data never reached the catalog. Promptly addressing the issue is essential to keep stock levels, prices, and product details accurate for shoppers.

Key Points

• System‑originated error — The fault is generated by Amazon’s backend, not by malformed files, missing columns, or any seller action.
• Uncertain data receipt — When 13100 appears, Amazon does not confirm whether any rows of the feed were stored; the entire batch may be lost.
• First‑line fix is a quick retry — Amazon advises waiting a few minutes and then resubmitting the same file or API call.
• Escalate only if it repeats — If the error persists after several attempts and no other error codes are reported, open a case with Seller Support and provide the error code, timestamps, and feed identifiers.
• Build resilience into bulk uploads — Automated pipelines should include logic to detect transient codes like 13100 and automatically retry after a short pause.

How Error 13100 Occurs

1. Submission launch — A seller initiates a bulk upload, for example a flat‑file CSV containing 5,000 SKUs, via the “Add Inventory” page.
2. Backend interruption — While Amazon’s ingestion service parses the file, an unexpected service outage (e.g., a database node restart) halts processing, triggering error 13100.
3. No acknowledgment returned — The system returns a failure response to the seller’s browser or API client, indicating that the feed was not accepted.
4. Temporary recovery — After the internal outage resolves—usually within a few minutes—subsequent submissions are processed normally.

Before / After Comparison

• Before: A seller uploads a 10 MB inventory feed at 02:15 UTC during a routine night‑time window. The feed is accepted, processing completes in 3 minutes, and the seller sees a “Success” status in the processing report.
