As we start the new year, we want to share an additional important migration date that will affect all third-party developed applications that are authorized by Selling Partners, and are in the Amazon Selling Partner Appstore (“public applications”).

On January 20, 2022, an escaping issue was identified affecting most Selling Partner API operations resulting in escape characters, such as quotes (") and backslashes (\), being double-escaped in API request and response payloads. This issue has been resolved. Please review the remainder of this announcement to determine if your application was impacted by this issue and if any follow up actions are necessary.

We're excited to launch this new documentation site for English Selling Partner API documentation.

We are looking forward to serving you new and improved products and services this year. Today, January, 19, 2022, is our first release of the year.
