Rest api testing using Postman tool

Explore soap and rest as web service models: soap uses XML with WSDL descriptions, while rest is a lightweight, resource-based approach with multiple formats.

Soap is heavy and defines its own security and standards, exposing business logic via a service interface; rest is lighter and enables access with multiple formats.
