Disadvantages of APIs

  • Cost: Developing and implementing API is costly at times and requires high maintenance and support from developers.
  • Security issues: Using API adds another layer of surface which is then prone to attacks, and hence the security risk problem is common in APIs.

What is an API (Application Programming Interface)

Everyone is in search of the highest-paying job so as to get into it. And, in the list, the web developer has been on the top for years and will remain in the same place due to its demand. If you’re the one who’s looking to get into it. you must be aware of the most important terms used in it. Out of all the terms, API is yet another term that plays a very important role in building a website. Now, what is an API – (Application Programming Interface)?

To make you clear with the diagram of what is API, let’s take a real-life example of an API, you can think of an API as a waiter in a restaurant who listens to your order request, goes to the chef, takes the food items ordered and gets back to you with the order. Also, if you want to look for the working of an API with the example, here’s one. You’re searching for a course(let’s say DSA-Self Paced) on the XYZ website, you send a request(product search requested) through an API, and the database searches for the course and checks if it’s available, the API is responsible here to send your request to the database (in search of the course) and responds with the output(best DSA courses).

What is an API?

API full form is an Application Programming Interface that is a collection of communication protocols and subroutines used by various programs to communicate between them. A programmer can make use of various API tools to make their program easier and simpler. Also, an API facilitates programmers with an efficient way to develop their software programs. Thus api meaning is when an API helps two programs or applications to communicate with each other by providing them with the necessary tools and functions. It takes the request from the user and sends it to the service provider and then again sends the result generated from the service provider to the desired user....

How do APIs Work?

The working of an API can be clearly explained with a few simple steps. Think of a client-server architecture where the client sends the request via a medium to the server and receives the response through the same medium. An API acts as a communication medium between two programs or systems for functioning. The client is the user/customer (who sends the request), the medium is the application interface programming, and the server is the backend (where the request is accepted and a response is provided). Steps followed in the working of APIs –...

Advantages of APIs

Efficiency: API produces efficient, quicker, and more reliable results than the outputs produced by human beings in an organization. Flexible delivery of services: API provides fast and flexible delivery of services according to developers’ requirements. Integration: The best feature of API is that it allows the movement of data between various sites and thus enhances the integrated user experience. Automation: As API makes use of robotic computers rather than humans, it produces better and more automated results. New functionality: While using API the developers find new tools and functionality for API exchanges....
