APIs need to change over time. Features are added, bugs are fixed, and changes are made. How can you introduce and track changes without breaking client applications? API versioning is the answer. By versioning your API, you work toward building a robust and scalable product.
What Is API Versioning?
Versioning an API is the process that allows tracking changes and managing the API's various iterations. Essentially, versioning allows you to create multiple API versions that that coexist but operate independently of each other. That way, new features can be added, updates can be made, and old features can be removed with minimal disruption of service to the user.
