+## **Understanding Data-Source and Data-Sink types**
+
+When working with transfer types, it’s important not to confuse transfer types with data-source and data-sink types. For example, `HttpData` refers to REST APIs typically used as data-sources or data-sinks for transfer types like `HttpData-Push`, while `AmazonS3` is the typical data-sink type for the `AmazonS3-Push` transfer type.
