XAPIVersion

XAPIVersion is a mechanism used to manage and identify different iterations of an API. It allows developers to evolve their APIs over time without breaking existing applications that rely on older versions. By incorporating versioning, changes can be introduced incrementally, ensuring backward compatibility or providing clear upgrade paths for users. Typically, API versions are represented by a number, such as 1.0, 1.1, or 2.0, and are often included in the API's URL or as a header. This approach helps in maintaining stability for clients while enabling the server-side to implement new features or fix issues. When an API version is updated, it signifies a potentially significant change, and applications may need to be modified to work with the new version. This is crucial for businesses and developers who depend on the reliable functioning of their integrated systems. XAPIVersion, in essence, is a contract between the API provider and its consumers, delineating the expected behavior and structure of the API at a specific point in its development lifecycle.
