Laajennusrajapinnat, known in English as extension interfaces or plugin APIs, are designed sets of rules and protocols that allow third-party software components, often called extensions or plugins, to interact with and enhance the functionality of a larger host application. These interfaces define how extensions can access the host's features, data, and user interface, as well as how they can contribute their own capabilities.

The primary purpose of extension interfaces is to promote modularity and extensibility. By abstracting the internal workings of the host application, developers can create new features or integrate external services without needing to modify the core codebase. This fosters an ecosystem where developers can specialize and innovate, leading to richer and more versatile applications.

Common elements of an extension interface include methods for registering extensions, communicating events between the host and extensions, providing access to application data structures, and defining how extensions can present their own user interface elements. The design of an extension interface is crucial for its usability and security, ensuring that extensions can be reliably integrated and do not compromise the stability or integrity of the host application.

Examples of applications that commonly utilize extension interfaces include web browsers (for add-ons and extensions), integrated development environments (IDEs) (for plugins), and content management systems (for themes and plugins). The availability and quality of an extension interface significantly impact the adaptability and longevity of the host software.
