Publish Extensions to Managed Packages
An extension is any package, component, or set of components that adds to the functionality of a managed package. An extension requires that the base managed package is installed in the org. For example, if you have built a recruiting app, an extension to this app can include a component for performing background checks on candidates.

Building a new app? Have you considered using second-generation managed packages? Flexible versioning and the ability to share a namespace across packages are just two reasons why developers love creating second-generation managed packages. We think you’d love it, too. To learn more, see: Why Switch to Second-Generation Managed Packages, and Comparison of First- and Second-Generation Managed Packages.
The community of developers, users, and visionaries building and publishing apps on AgentExchange is part of what makes Salesforce Platform such a rich development platform. Use this community to build extensions to other apps and encourage them to build extensions to your apps.
When working with both first-generation (1GP) and second-generation (2GP) managed packages, only certain combinations of packages are supported. See: Which Package Types Can Your Package Depend On?
To publish extensions to a managed package:
-
Install the base package in the Salesforce org that you plan to use to upload the extension.
-
Build your extension components.
To build an extension, install the base package and include a dependency to that base package in your package. The extension attribute automatically becomes active.
-
Create a package and add your extension components. Salesforce automatically includes some related components.
-
Upload the new package that contains the extension components.
-
Proceed with the publishing process as usual. For information on creating a test drive or registering and publishing your app, go to Salesforce Partner Community.
Packages can’t be upgraded to Managed - Beta if they’re used within the same org as an extension.
