Available Extensions

This page lists all the extensions that are available for Salesforce Commerce. New extensions are added as they become available.

To create an extension provider, you must know which base Apex class to extend and the extension point name for mapping. Both the the base Apex class name and extension point name are listed for each extension.

This page lists two types of extensions: domain and endpoint.

Domain extensions extend functional domains, such as cart calculation. In contrast, endpoint extensions extend selected Connect API endpoints.

important: The release status and availability varies from extension to extension. This page is updated to reflect the latest release status of each extension.
