How are APIs versioned in the Anypoint Platform?

APIs are versioned in the Anypoint Platform primarily by appending version numbers in the API URL or by utilizing versioning in RAML (RESTful API Modeling Language). This method allows developers and consumers to easily identify and access different versions of an API, ensuring that each version can evolve independently without impacting existing clients that may depend on earlier iterations.

Versioning in the URL is a common practice, making it straightforward for users to understand which version they are working with. For example, an API might be structured as https://api.example.com/v1/resource for version 1 and https://api.example.com/v2/resource for version 2. This clear delineation helps prevent conflicts and confusion among API consumers.

Using RAML for versioning provides a structured way to define different behaviors, methods, and resource representations for each API version. RAML allows for robust documentation that keeps the versioning and changes in the API transparent and well-managed.

The other choices suggest methods not typically relied upon for versioning APIs directly. Separate environments can manage various instances or deployments but do not inherently address the distinct functionality of different API versions. Rollbacks address reverting to a previous state of an API rather than establishing multiple versions for ongoing use. Lastly
