# About Velo APIs and the SDK

You can now use the [Wix JavaScript SDK](https://dev.wix.com/docs/sdk.md) instead of Velo APIs for most functionality when developing sites or building apps with Blocks. This marks the beginning of a gradual transition from using Velo APIs to using the next generation SDK. You are encouraged to start using the SDK in all new and ongoing development projects.

The APIs listed in this section of the Velo reference have SDK counterparts that you can start using now. Although you can continue to use the Velo versions of these APIs, they will not receive any future updates. 

For more information about how to migrate existing Velo code to use the SDK, see [Migrate from Velo to the SDK](https://dev.wix.com/docs/develop-websites/articles/coding-with-velo/develop-with-the-sdk/migrate-from-velo-to-the-sdk.md).
