REST (Representational State Transfer) API allows you to use HTTP requests to GET, PUT, POST, and DELETE data.
Through the user interface of Talend Data Mapper, you can easily import a REST API description from a REST API metadata node and immediately view the content of the node.
After you import a REST API description using the REST API Definitions option, Talend Data Mapper extracts the descriptions of the data structures and creates a Structure with a default JSON representation.
