Introduction
What is an API? An API is a mechanism that enables two components to communicate with each other using a set of protocols.
API stands for Application Programming Interface. They can simplify app development saving time and money. Using API you can send and receive messages on your device frequently. When you use an app like facebook, you are using API. The application connects to the Internet and sends data to a server.
The server then retrieves that data, interprets it, performs the necessary actions and sends it back to your phone. APIs are a simplified way to connect your own infrastructure through cloud-native app development, but they also allow you to share your data with customers and other external users. API further simplifies how a developer integrates a new application into an existing architecture.
How does an API works?
- A client application requests an API call to retrieve information.
- After receiving a valid request, the API makes call to the external program.
- The server sends a response to the API with the requested information.
- The API transfers the data to the initial requesting application.
Why do we need APIs?
- APIs can help with your business strategy.
- APIs assist in data management.
- Promotes business growth.
- Enables data integration across multiple platforms.
- Makes fata accessible and has 3rd party integration.
- Simplicity, Efficiency and customization
