SP-API Throttling Adjustments

Vendre sur Amazon MWS Announcements
1

Effective August 31, 2022, we will be adjusting the rates across select API operations within the Catalog Items API, Product Fees API, and Product Pricing API. These adjustments will lower the rates of the 1x1 APIs. We encourage you to call the equivalent batch APIs for use cases requiring a higher volume of data.

What is changing?

  • listCatalogCategories will change from rate/burst of 1/40 to 1/2.
  • getCatalogItem (GET /catalog/2020-12-01/items/{asin} and GET /catalog/2022-04-01/items/{asin}) will change from rate/burst of 5/5 to 2/2.
  • searchCatalogItems (GET /catalog/2020-12-01/items and GET /catalog/2022-04-01/items) will change from rate/burst of 5/5 to 2/2. For high-volume use cases, use the multi-query capability in GET /catalog/2022-04-01/items.
  • getMyFeesEstimateForSKU and getMyFeesEstimateForASIN will change from rate/burst of 10/20 to 1/2. For high-volume use cases, use getMyFeesEstimates, which accepts batch sizes up to 20.
  • getPricing and getCompetitivePricing will change from rate/burst of 10/20 to 0.5/1. These operations accept a list of up to 20 items.
  • getListingOffers and getItemOffers will change from rate/burst of 5/10 to 1/2. For high-volume use cases, use getListingOffersBatch and getItemOffersBatch, which accepts batch sizes up to 20.
  • The Catalog Items v0 operations listCatalogItems (GET /catalog/v0/items) and getCatalogItem (GET /catalog/v0/items/{asin}) will be deprecated on September 30, 2022.
