OUR TAKE
Network is now programmable, making coding a valuable skill for network engineers. Network APIs have effectively replaced the traditional CLI. Those who embrace automation will thrive in the evolving tech industry, while those who neglect this opportunity risk becoming irrelevant in some companies.

An API enables communication between two applications, while a network API provides communication between the network infrastructure — and its protocols — and applications.
what is an API?
APIs play a crucial role in streamlining application and software development by enabling the integration of data, services, and functionalities from existing applications, thus eliminating the need to build them from the ground up. They also offer a secure and straightforward method for application owners to share their application data and capabilities with internal departments, as well as with external business partners and third parties. This selective information sharing capability ensures system security by concealing internal system details while allowing the exchange of specific data packets relevant to each request. Moreover, comprehensive API documentation serves as a technical guide for developers, empowering them to effectively utilise the API’s services, ultimately contributing to a more seamless and successful API experience for users.
How do APIs work?
API communication can be understood as a request and response interaction between a client, the application submitting the request, and a server which provides the response, with the API acting as the bridge between them. For instance, in third-party payment processing on an e-commerce site, when a user opts to “Pay with PayPal”, APIs facilitate this connection. When the buyer clicks the payment button, an API call, known as the request, is sent to retrieve necessary information from the web server through the API’s Uniform Resource Identifier (URI), including a request verb, headers, and sometimes a request body. Upon receiving a valid request, the API forwards it to the external program or web server—in this case, the third-party payment system. The server then responds with the requested information, which the API transfers back to the initial requesting application, such as the product website. Despite variations in data transfer methods depending on the web service, all requests and responses occur via the API, ensuring a seamless connection that remains invisible to the user.

Why are APIs important?
APIs offer numerous benefits that simplify the design, development, integration, and management of applications. They foster improved collaboration by enabling seamless communication between various platforms and apps, automating workflows, and enhancing workplace productivity. APIs also drive accelerated innovation as they facilitate connections with new business partners, opening up opportunities for expanding services and accessing new markets. Additionally, APIs can be monetised by selling access to valuable digital assets, thereby creating an API economy. From a security perspective, APIs provide layers of protection by separating the requesting application from the responding service and implementing authentication credentials and additional security measures during data exchange. Moreover, APIs contribute to user security and privacy by allowing users to control access to their personal information and granting permissions based on their preferences and consent. Overall, APIs play a pivotal role in enhancing collaboration, driving innovation, monetising data, ensuring system security, and safeguarding user privacy.
APIs are foundational to the functioning of networks by enabling robust communication, integration, automation, scalability, security, and innovation. They are indispensable tools for building connected, efficient, and secure digital ecosystems.
A web service is an internet software component that facilitates data transfers over a network, effectively making every web service an API since it exposes an application’s data and functionality to other applications. However, not all APIs are web services because APIs serve as intermediaries between any two disconnected applications, while web services specifically require a network connection and are typically private, accessible only to approved users. In the context of microservices and cloud-native development, microservices architecture divides an application into smaller, independent components often connected by REST APIs. This approach allows developers to work on individual components independently, enhancing testing, maintenance, and scalability. The prevalence of microservices has grown alongside cloud computing, and together with containers and Kubernetes, it forms the foundation of cloud-native application development.
