APIversioinnilla, or API versioning, is a strategy used in software development to manage changes to Application Programming Interfaces (APIs) over time. As APIs evolve, new features are added, existing ones are modified, or bugs are fixed. Versioning ensures that existing applications and services that rely on an older version of the API can continue to function without breaking, while also allowing for the introduction of new functionalities or breaking changes in newer versions.

There are several common approaches to API versioning. One is URI versioning, where the version number is included directly in the API endpoint's Uniform Resource Identifier (URI), such as `/v1/users` or `/v2/users`. Another method is header versioning, where the version information is passed in HTTP headers, for example, using a custom header like `X-API-Version: 1`. Query parameter versioning is also used, where the version is specified as a query parameter in the URL, like `/users?version=1`.

Choosing an appropriate versioning strategy is crucial for maintaining backward compatibility and providing a stable developer experience. It allows developers to gradually migrate to newer API versions at their own pace, reducing the risk of unexpected disruptions. Effective versioning also helps in deprecating older API versions gracefully, communicating changes clearly to users, and managing the lifecycle of an API. Without proper versioning, API updates could lead to widespread compatibility issues and negatively impact user adoption and trust.
