# REST Client

The REST client transformation step enables you to consume RESTful services. Representational State Transfer (REST) is a key design idiom that embraces a stateless client-server architecture in which web services are viewed as resources and can be identified by their URLs.

**Note:** The data of the input fields can be escaped by the Calculator step and the function **Mask XML content from string A** or **Escape HTML content**.
