Overview

Amazon sellers who upload promotions via inventory feeds may see error code 30010 when the promotion type field contains an invalid value. The error signals that the “Type” entry does not align with any of the promotion types Amazon’s feed processor recognizes. Fixing the value is essential because a rejected feed postpones the activation of time‑sensitive deals and can cost sellers sales during peak traffic periods.

Key Points

• Error 30010 definition — The feed processor flags the record when the “Type” column contains a string that Amazon does not list as a valid promotion type. For example, entering “DiscountPurchase” instead of the exact term triggers the error.
• Only two feed‑compatible types — Amazon currently accepts PurchaseDiscount and PurchaseDiscountShipping as the sole promotion types in feed uploads. Any other label, such as “FreeShip” or “BuyOneGetOne,” will be rejected.
• Case‑sensitivity and spacing matter — The feed parser treats “purchasediscount” and “PurchaseDiscount ” (with a trailing space) as incorrect, even though the meaning appears identical to a human reviewer.
• Common sources of the mistake — Manual edits, outdated third‑party templates, or copy‑pasting from old documentation often introduce hidden characters or subtle typos that cause the mismatch.
• Impact on promotion timing — Because the feed is rejected, the promotion never appears on the marketplace until the seller corrects the type and resubmits, potentially missing holiday spikes or Lightning Deal windows.

How Promotion Feed Validation Works

1. Feed ingestion — Amazon’s backend reads each line of the uploaded promotion file and extracts the “Type” field. Example: A seller submits a CSV row with Type=PurchaseDiscount.
2. Value comparison — The system checks the extracted string against a whitelist that contains only “PurchaseDiscount” and “PurchaseDiscountShipping.” Example: The same row is compared; if the value matches exactly, the check passes.
