 # Hurl Client
 
-> This extension was developed to serve as the HTTP client for the [WSO2 Integrator](https://marketplace.visualstudio.com/items?itemName=WSO2.wso2-integrator).
-
 Open, edit, and execute `.hurl` files as interactive notebooks in VS Code.
 
 Each HTTP request in a `.hurl` file becomes a runnable notebook cell. Responses are displayed inline as formatted Markdown — status code, response body (pretty-printed JSON), and assertion results. Markdown cells provide rich documentation between requests.
