First-Generation Managed Packaging Developer Guide
jPublish 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.

The community of developers, users, and visionaries building and publishing apps on AppExchange 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.
- 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.
