October 2023 SP-API Release Announcement

Introducing Version 2.0 of the Java and C# SDKs

On October 2, 2023, we announced that SP-API no longer requires AWS IAM or AWS Signature Version 4, which means that developers no longer need to register for IAM resources or sign SP-API requests with AWS Signature Version 4.

Along with this announcement, we launched Version 2.0 of the Java and C# Software Development Kits. Version 2.0 saves request signing time and provides more details about the errors returned during LWA authorization through the new custom LWAException. SDK Version 1.0 for Java and C#, with optional AWS signing, are still available but will be deprecated by the end of 2023.

For more information on connecting to SP-APIs using SDKs, refer to Automate your SP-API calls using Java SDK and Automate your SP-API calls using C# SDK.

SP-API documentation is now available in multiple languages

We launched multi-language content on the SP-API Documentation site! Developer documentation, including announcements and migration content, is now available in English, Japanese, and Simplified Chinese with plans for future language expansion. The SP-API Blog is now available in German, Spanish, French, Italian, Portuguese, Turkish. You can toggle between different languages and the page will automatically refresh and display the new language.

A+ Content API v2020-11-01 usage rate changes

The A+ Content API v2020-11-01 usage rates will be lowered from a rate of 10 to a rate of 1 in late December. This change improves the experience and reduces instances where throttling is applied to requests due to uneven call patterns.

Update to getItemOffers in Product Pricing API v0

The listingPrice attribute in the getItemOffers response was renamed to help developers avoid errors when extending their code for business-to-business use cases. The Landedprice and Shipping sub-fields are no longer required, but optional.

Listings Items API 2021-08-01 ItemProcurement element updated from an object to an array

The ItemProcurement data element was updated from an object to an array. This update does not change the API response.

Updated response for getOrderItems in Orders API v0

A list of associated items was added to the response for the getOrderItems operation. An associated item is an item such as a value added service purchased with a product. For example, a tire installation service purchased with tires.

Known Issue Fix for Sales and Traffic report in BE

A known issue for customers in the Belgium marketplace requesting the GET_SALES_AND_TRAFFIC_REPORT has been fixed. Integrators can now successfully request the Sales and Traffic report in BE.
