What is an API?
An "application programming interface," or API, is a software bridge that enables communication between two applications and exchanges data with each other.
An example to understand an API :
Consider that you are going to a restaurant where the "waiter" plays a vital role, since you won't go to the kitchen to get your order or tell the kitchen crew what you want; instead, the waiter will handle all of this for you. The API performs a similar function by receiving your request, informing the system of what you want, and responding to you.
Features of an API:
- It provides a useful service (data, function, audience, etc.).
- It provides excellent developer support.
- Not only that, but it helps you plan a business model.
- Simple, flexible, quickly adopted.
Types of API:
- Open or Public API: These APIs are accessible to the public. Additionally, it has not imposed any limitations on their use.
- Partner APIs: Since they are not accessible to the public, specific rights or licenses are required to access this kind of API.
- Internal APIs: Companies create these APIs to use in their internal systems. You can use it to increase your teams' output.
- Composite APIs: These APIs mix several data and service APIs.
Examples of Web APIs:
- The YouTube API enables developers to incorporate YouTube functionality and videos into websites and applications.
- Developers can access Amazon's product choices through the Amazon API.
