Application program interface (API)
Application program interface (API) is a software that allows applications to communicate with each other. Its methods include sending and receiving data and performing other tasks.
Application Program Interface(API) software enables communication between applications. Applications communicate with each other using a set of definitions and protocols. Whenever API is used, data is sent to the server, which sends back the data after performing its actions. Some instances where API is used are using a rideshare app, adjusting the thermostat from your phone, and making a mobile payment.
This satisfies the query of receiving what you ask. Modern APIs are equipped with HTML and REST standards that are easy for developers to use, understand, and maintain. Thus, they focus on security and performance, and share the necessary data.
There are generally four types of APIs;
- Public APIs- available publicly to developers and other users in a moderate way.
- Partner APIs- not available publicly and require specific access to use.
- Internal APIs are used within an enterprise and are also limited to itself.
- Composite APIs- combine two or more APIs, which can solve complex API behaviours.
