The Application Management API is now available for Amazon Business developers. With this API, you can programmatically rotate your Login with Amazon (LWA) credentials (client secrets). This change applies to all Amazon Business stores/geographies. For more information about how to rotate your client secret with the Application Management API, see How to rotate your app's LWA client secret. For any questions about client secret rotation, please reach out to your Amazon Business contact.

We are excited to share the latest updates to our APIs and documentation for October 2024:

On August 9th, Amazon Business launched enhanced seller fields for the Reporting API. These fields give business customers more information about a seller’s diversity certifications, including the issuing agency and expiration date for each certificate. The API has also been updated to return a detailed physical address for each seller. For more information, see Release Notes 2024.

Effective immediately, a new identity verification step has been added to the developer onboarding process.

On May 10th, Amazon Business launched support of credit memo PDF documents via Document API for EU and JP. This gives business customers flexibility to view their credit memo PDF’s for their returns or expected refunds from their seller (Supports IBA, Retail, VCS, VCS-lite credit memos in EU) and retail credit memos in JP.

Three Amazon Business APIs have been enhanced with new features and one guide has been updated since the last release.

Starting November 1, 2023, Amazon Business APIs no longer require the use of AWS Identity and Access Management (IAM) or AWS Signature Version 4. This means developers don’t need to register for IAM resources or sign an Amazon Business API request with AWS Signature Version 4.

On September 12, we launched Ratings and Reviews feature on Amazon Business App Center. This will help app developers and partners like you to gather valuable customer feedback on app’s overall customer experience, well-used functionalities, and desired features. This feature helps businesses decide which app to connect and use based on the ratings and reviews.

Product Search API has been enhanced with two features. Refer to 2023 August release notes.
The content on Amazon Business Developer Hub is now available in Japanese language. Two guides, Product Search API customer experience guidelines and Integrated Quoting workflow, have been updated. Refer to Documentation updates.

By October 31, Amazon Business Developers, must rotate their applications (apps) Login With Amazon (LWA) credentials (client secret). Rotation of the LWA client secret is required every 180 days thereafter. Your LWA client secret will stop working after 180 days, causing the app to lose access to Amazon Business APIs. This includes the inability to make successful API calls, which may directly impact any customers who authorized your app.
