What is an API?
Last Updated 2025-03-06 UTC+8.
An Application Programming Interface (API) serves as a protocol that facilitates communication between various software components. It outlines the methods through which data can be requested and exchanged, providing a standardized interface for different systems to interact seamlessly.
For instance, when Developer A creates a module, they define the API specifications that Developer B can utilize. These specifications encompass the properties, methods available for use, the purpose of the API, and instructions on how Developer B can seamlessly integrate these APIs into their system.
The advantages and disadvantages of APIs share similarities with those of SDKs. For more detailed insights, please refer to this webpage.
