Today, AWS Marketplace launched fine-grained IAM permissions to enable AWS Marketplace sellers to precisely control access to various features in AWS Marketplace Management Portal (AMMP). AWS Marketplace sellers, including Independent Software Vendors (ISVs) and channel partners, can now provide granular access to data and various features such as controlling which users can update tax information in AMMP within their organizations. This launch will enable granular permissions management for sellers in AMMP and will have a consistent authorization model across all AWS services that work with IAM.
