# InstalledAddOns Resource

> \[!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).

The InstalledAddOns resource allows you to install, configure, and manage installed Add-on Listings for an Account. Multiple instances of an Add-on Listing can be installed on an Account, each with a different configuration.

> \[!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.

## Install an Add-on Listing

`POST https://marketplace.twilio.com/v1/InstalledAddOns`

To install an Add-on Listing within your Account, you need to find its AvailableAddOn SID. You can do this by [listing all AvailableAddOn resources](/docs/marketplace/api/available-add-ons#list-all-availableaddon-resources) and finding the SID of the one you wish to install. The AvailableAddOn resource also shows the information required for installing the Add-on Listing.
