To access custom metadata types in Flow Builder, which option should you use?

To access custom metadata types in Flow Builder, the most appropriate way is to use the Get Records element. This element is specifically designed to retrieve records of any kind, including custom objects and custom metadata types.

When you utilize the Get Records element, you can specify the API name of the custom metadata type you want to access and create filters relevant to your needs. This allows you to retrieve specific fields from the custom metadata records and utilize them within your flow logic.

The other options, while they might sound relevant, do not specifically provide a straightforward means of accessing custom metadata records within Flow Builder. The $Metadata global action is intended for accessing metadata about various components in your Salesforce environment but does not directly fetch record data required for flow. The Custom Metadata resource type is not an existing option within Flow Builder as of the latest training. The Get Metadata action is typically not used within Flow Builder to access standard or custom metadata records directly.

Thus, the Get Records element stands out as the correct and preferred approach for accessing custom metadata types within Flow Builder, offering a clear, functional method to work with those records in your automation processes.
