Which Chrome application is used to interact with APIC-EM via REST APIs?

Postman is a powerful and user-friendly application designed for interacting with REST APIs, including the Application Policy Infrastructure Controller Enterprise Module (APIC-EM). It allows users to construct and send HTTP requests to APIs, as well as view the responses in a structured format. This makes it particularly suitable for developers and network engineers who need to test, debug, and explore API functionalities.

In the context of APIC-EM, which provides a centralized controller for managing and automating network services, Postman simplifies the process of working with the various RESTful APIs exposed by the controller. Users can easily configure parameters, headers, and body content for their requests, making it an effective tool for interacting with the APIC-EM's capabilities, such as network automation, policy management, and monitoring.

The other options, while relevant in different contexts, do not serve the same purpose as Postman. IWAN is related to Intelligent WAN solutions, Network Plug and Play focuses on device provisioning and onboarding, and Python 3 is a programming language that can be used for API interactions but requires coding. None of these alternatives provide the straightforward interface and functionality that Postman delivers specifically for REST API interactions with APIC-EM.
