Today we know about interesting topic what is an API? and How it works? Is APIs Useful to build a great architecture? These all thing covered in this blog. So, Guys take an attention to know all these things. Explain about APIs and it’s Architecture let’s check it.

What is an API:

Application Programming Interface (API). It is a Software mediator that allows two applications to meet each other.  In another way, API is a messenger type that supplies you information to the supplier that you are requesting it from and supplies the answer we need back to you.  API contains a combination of protocols, routines, and tools for building the software application. It is like a method for products and services to interact with each other through a documented interface. App developers can grasp an API with no difficulty and call it via a mobile application, web browser.

Let’s see a perfect example of API that will easily understand what is an API?

How do APIs work?

 To understand clearly about an API, let’s us take the familiar case in our daily life?

Form a mental image, you are in the restaurant sitting on the table with a menu of choice order from. Imagine “system” in the place of Kitchen that will arrange your order. Some critical link is missing right! to exchange your information i.e. your order to the kitchen and supply your food back to your table. The server(or) waiter is the messenger-or API- that takes your appeal or order and tells the kitchen what you want-the system-what to do. Then the server supplies the response back to you what you want: in this example, it is food. I think this example is enough to understand the what is an API?Explain about APIs and it's Architecture

Types of API’s:

There are numerous types of APIs. Web APIs the common one these APIs are also known as Web services, it provides to communicate the web applications. In public APIs the count will be in thousands that can be used to do everything from updating your social media, checking traffic and make payments.

Private APIs are more Compare to public APIs. These API’s used by the companies to increase their services. These APIs are not available to be consumed by public services.

More advanced Web APIs are there such as Remote Procedure Call (RPC), Simple Object Access Protocol (SOAP), and maybe the most famous -at the very least name-As Representational State Transfer (REST) or RESTful become most popular.

 Is API’s is Useful to Build a Great Architecture?

We generally say that APIs are the technique to communicate data, applications that will give your company greater flexibility. But how an APIs work from an architecture viewpoint? Focus attention on three layers

  1. System APIs
  2. Process APIs
  3. Experience APIs

In APIs, architecture system APIs is used to create building blocks that can reuse by anyone in the company focus on the opportunity to approach to use same data. System APIs reveal data through a combination of RESTful services that designed in RAML, making it very easily intended to used up and then replaced by any developer within the company. Process APIs implement a specific function, give access to non-central data. Coming to the Experience APIs are the means by which data can be configured differently so it is very easily taken by its studies audience, all from a common data source.

Generally three-layered construction allows for a smooth and continuous flow of data from systems of record to a new experience. This approach provides greater flexibility through loose connections.

MuleSoft identifies top 5 reasons why APIs are taking center stage for the organization

  1. Enabling applications (71%)
  2. Sharpness (67%)
  3. Ability to enable partners and affiliates (56%)
  4. Driving new ideas (47%)
  5. Charming and developing new channels (47%)

For above those reasons APIs play a major role in MuleSoft

Recommended audience:

Software developers

Project managers

Non- technical people


It’s good to have knowledge on programming languages like JAVA and a basic understanding of data formats such as XML, CSV, JSON and typical integration technologies such as  HTTP, JMS, JDBC, REST and SOAP. But it is not mandatory skills. Trainers will teach you if you don’t have knowledge of above-mentioned technologies.
