What is API?
An API (Application Programming Interface) is an application programming interface that enables communication between different systems, applications, and services. It is a set of rules, protocols, and methods that define how data is exchanged and software interacts.
An API acts as an intermediary, allowing applications to access the functions and data of other systems without needing to know their internal architecture. In practice, this means that programs can use pre-built API methods to send and receive information, greatly simplifying the integration of different technologies.
APIs are widely used in the modern digital world—from mobile apps and websites to IoT systems and artificial intelligence. Their applications include retrieving weather data, processing online payments, and communicating between cloud services.
Thanks to the API, it is possible to automate processes, extend application functionality and integrate various platforms quickly and efficiently.
How does the API work?
An API operates on a set of rules and protocols that define how systems interact. Key elements of an API include:
- Requests – The application sends a request to the API with specific parameters.
- Responses – The API returns the appropriate data or operation results.
- Communication protocol – The most commonly used are REST (HTTP) and SOAP.
Types of APIs on the market
APIs can be divided into several categories based on their function and use. Here are the most important API types available on the market:
1. Public APIs (Open APIs)
Public APIs are available to all users and can be used by any company or developer. Examples include the Google Maps API, OpenWeather, and Twitter API.
2. Private APIs
Private APIs are used internally by organizations and are used to integrate different systems within a single company. They enable better automation of business processes.
3. Partner APIs
Partner APIs are made available to selected business partners based on an agreement. They enable the integration of services between companies, for example, online payment systems provide APIs to selected merchants.
4. System APIs
System APIs enable communication between different modules of the same application or system. They are used, for example, in ERP or CRM systems.
5. REST APIs
REST (Representational State Transfer) APIs are widely used in web and mobile applications. They use the HTTP protocol and either JSON or XML formats.
6. SOAP API
SOAP (Simple Object Access Protocol) is an older API standard that is often used in enterprise systems requiring a high level of security.
7. GraphQL API
GraphQL is a modern alternative to REST, allowing you to retrieve only the data you need, which increases the efficiency of your queries.
8. WebSocket API The
WebSocket API enables real-time, two-way communication between a client and a server. It is used in applications such as web chats and stock market applications.
Thanks to various types of APIs, it is possible to effectively connect systems and applications, which improves the operation of the digital world.
Why is API important?
APIs play a key role in the digital world, enabling:
- Process automation – elimination of manual activities.
- System integration – combining different applications into a coherent ecosystem.
- Scalability – the ability to easily expand functionality.
- Security – control of access to data and functions.
API is the foundation of modern IT solutions, enabling efficient exchange of data and functionality between systems.

API FAQ – Frequently Asked Questions and Answers
What is API?
An API (Application Programming Interface) is an interface that enables communication between different applications. It allows programs to exchange data and use the functions of other systems without needing to know their internal structure.
How does the API work?
An API works by sending requests and receiving responses. The application sends a request to the API with specified parameters, and the API returns the appropriate data or operation results.
Why use API?
APIs facilitate the integration of various systems, automate processes, and enable the rapid development of application functionality. APIs enable companies to effectively connect various services and optimize the performance of their systems.
What types of APIs are there?
APIs are divided into public (available to everyone), private (used internally by the company), partner (available to specific partners) and system (for communication between application modules).
What is the difference between REST API and SOAP API?
REST is a lightweight and popular HTTP-based API often used in web applications. SOAP is an older standard that offers greater security and structure but requires more complex processing.
What are some examples of popular APIs?
Popular APIs include Google Maps API (maps), Facebook Graph API (social media integration), Stripe API (online payments), and OpenWeather API (weather data).
What methods are used in the API?
The most commonly used methods in the REST API are GET (retrieving data), POST (sending data), PUT (updating data) and DELETE (deleting data).
Is the API secure?
API security depends on the security measures used, such as API key authentication , OAuth , or SSL/TLS . Restricting API access and monitoring requests are also important.
How to start using the API?
To use the API, you must register for the service , obtain an API key (if required), read the documentation, and perform your first test queries.
What tools help you work with the API?
API testing uses tools like Postman (for sending requests), Swagger (for API documentation), and cURL (for interacting with the API in the terminal).
