Overview

Amazon has revised the rate limit for the getItemOffersBatch call in its Product Pricing API. The change, effective July 10 2023, reduces how many bulk pricing requests sellers can send per second. Sellers who pull large volumes of pricing data must adjust their code now to keep listings accurate and avoid throttling.

Key Points

• New Effective Date — The limit change takes effect on July 10 2023, giving developers an extra month beyond the original May 1 announcement to test and adapt.
• Reduced Throughput — Calls per second for getItemOffersBatch will drop from the previous 10 to 5, halving the speed at which bulk pricing can be retrieved.
• Batch Size Unchanged — Each request can still include up to 50 ASINs, but the overall number of ASINs processed per minute will be lower because of the throttled cadence.
• Documentation Updated — The Product Pricing API reference now lists the new limit and includes guidance on handling throttling responses, ensuring developers have the latest information.
• Pricing Feed Lag — Slower data pulls may delay updates to your pricing feed, potentially leaving some listings behind competitors if not scheduled carefully.
• Developer Alert — Amazon will notify registered developers via email when the new limit is enforced, so you can confirm that your integration is compliant.
• Extended Testing Window — The shift to July 10 allows you to run integration tests against the new constraints before the final cut‑over, reducing the risk of outages.
• 429 Status Code — Exceeding the limit will return a 429 Too Many Requests response, requiring your application to implement retry logic to stay within bounds.
• Monitoring Recommendations — Amazon suggests using CloudWatch metrics to track API usage and detect throttling events early, helping you maintain smooth operations.
• Support Availability — Seller Support will be on hand during the transition period to answer migration questions and troubleshoot issues related to the new limit.
