# Installed Add-ons Extensions Subresource

> \[!WARNING]
>
> The Preview API for this resource is deprecated. To migrate from Preview to V1, refer to the Marketplace API migration guide for [users](/docs/marketplace/listings/api-migration-users) or [publishers](/docs/marketplace/publishers/api-migration-publishers).

This subresource of the [Installed Add-ons resource](/docs/marketplace/api/installed-add-ons) allows users to fetch an Extension, view a list of Extensions, or update an Extension associated with an Installed Add-on Listing. An Extension describes the specific feature or API endpoint of a Twilio product in which an Add-on Listing can be used. Extensions are disabled by default, and can be enabled using Update endpoint.

> \[!NOTE]
>
> This API only supports Add-on Listings that are in General Availability (GA) or Beta state. Listings that are labeled as Coming Soon or Developer Preview are not accessible via the API and must be managed in the Console.
