Additionally, it has the ability to peek inside the HTTP headers and data payloads to perform additional checks and transformations. Therefore this building block is also responsible for authentication and authorization. It also guards against abuse of the API.Įven more important is the handling of unauthorized access to API. This is to ensure that the client applications do not misuse the API. Some of the most apparent control mechanisms include rate limiting, throttling, blacklisting. This is where the API request and responses are interpreted, and additional control mechanisms are applied via the Controller block. API Controller Blockīeyond the interface, an API needs to control the ingress and egress traffic. In this case, the API endpoints are identified by a topic name instead of the URL. It is based on the publish-subscribe pattern and makes it easy to build async APIs. One of the other popular protocols is MQTT.

The API interface also defines additional HTTP headers. Therefore the API interface is defined in terms of the API endpoint URL, the port number, and the HTTP method. HTTP is the most ubiquitous protocol that carries the API payload. In most cases, these specifications are governed by the application layer protocol that hosts the API. This is important for the external world to access the API. The Interface block is responsible for defining the specifications for the API. In this way, we stitch the building blocks that define the generic API architecture. To better understand the API architecture, let us split the API responsibilities into individual entities accountable for them.

Data Processing: All applications rely on some data store that necessitates transfer, dump, or fetching of loads of data.

Therefore it requires a computing environment.

Computing: As part of its core function, an API executes a business logic.

This is done to take additional actions or translate between human and machine, user and platform interpretable data formats. Interpretation: The data sent as part of an API request and response is subjected to interpretation.In the context of a web API, this interface defines the protocol specifications for accessing the API over the Internet. Interfacing: The interface defines the specifications for accessing the API.There are four primary responsibilities of an API. However, before getting to that, defining the core responsibilities of an API is crucial.Īs evident from its acronym, an API provides a mechanism for invoking a task on another system. It is possible to envisage an API architecture in the same way. But, collectively, they achieve the transmission of data between two devices through the Internet. Individually, they perform a single, well-defined responsibility. They are all arranged in a specific order. For example, if we look at the TCP/IP protocol, many layers form the building block of this protocol stack.

What is API Architecture?ĪPI architecture refers to a software building block that implements an API. We cover the innards and also delve further into the guidelines for building robust APIs. Through this blog post, we intend to build a technical awareness of API architecture. This architectural shift brings in new opportunities and challenges for software developers. Instead of embedding a bunch of APIs within, entire software systems are being conceptualized as APIs. Therefore, we are witnessing a radical shift in the evolution of software architecture. With the rise of the “as-a-service” model of software delivery, APIs also offer a consistent pattern for building modular and scalable systems.

APIs represent a significant part of any web-enabled software.
