Metadata Namespace

The Metadata namespace provides classes and methods for working with custom metadata in Salesforce

Salesforce uses metadata types and components to represent org configuration and customization. Metadata is used for org settings that admins control or configuration information applied by installed apps and packages. Use the classes in the Metadata namespace to access metadata from within Apex code.

Metadata access in Apex is available for Apex classes using API version 40.0 and later.

For more information, see Metadata.

The following are the classes in the Metadata namespace.
