Furthermore, Tooling API provides both SOAP and REST interfaces.

With Tooling API, you can add features and functionality to your existing Lightning Platform tools or build dynamic modules for Lightning Platform development into your enterprise integration tools. 

It also allows you to build specialized development tools for a specific application or service. 

Overall, Tooling API exposes metadata used in developer tooling, which you can access through REST or SOAP. 

By leveraging its features, you can streamline your development process and improve the functionality of your Lightning Platform applications.
