Important! EU and NA Marketplace - Rotate your LWA client secret for all apps every 180 days

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.

All Amazon Business apps that have client secret older than 180 days are affected. This change applies to EU and NA Amazon Business marketplaces.

For guidance on rotating a client secret, refer to How to rotate your app’s LWA client secret.
