Installed Package Types

Marketing Cloud has two types of installed packages: packages with enhanced functionality and packages with legacy functionality. Various details make it easy to tell whether you’re looking at a legacy package or enhanced package. All legacy packages have a banner at the top indicating that it’s a legacy package and a Licenses tab. Enhanced packages have an Access tab.

We recommend creating packages with enhanced functionality to use the latest updates and enhancements, including OAuth 2.0 functionality.

As of August 1, 2019, Marketing Cloud has removed the ability to create legacy packages. All new packages are enhanced packages.
