RESTful web service
Briefly

Representational State Transfer (REST) is a widely accepted architectural style for creating web services, recognized for its simplicity compared to alternatives like SOAP and WSDL. It utilizes the Hypertext Transfer Protocol (HTTP) for communication among connected devices in a network, utilizing standard HTTP verbs (GET, POST, PUT, DELETE) for data retrieval and manipulation. RESTful services typically return data in XML or JSON format, with JSON becoming increasingly popular. It offers a structured approach that promotes efficient interaction among Internet of Things (IoT) devices and applications, as it is built on existing web architecture.
REST has gained widespread acceptance across the Web as a simpler alternative to other Web services like SOAP and WSDL.
By leveraging a lightweight and universal protocol like HTTP, engineers are guided to create RESTful web services.
