API versioning

API versioning is the practice of managing changes to an application programming interface (API) over time. Just like software updates, APIs can evolve with new features or improvements. Versioning ensures that developers using the API can still work with older versions without breaking their applications. By assigning a version number—such as v1, v2, etc.—API providers signal to users which version they’re accessing and can maintain compatibility as they introduce changes. This way, users can upgrade at their own pace while developers can innovate without disrupting existing services.
