Some API vendors choose a combination of URI versioning and HTTP header versioning approaches, where the major version information is kept along with the URI and the minor version information for subresources is stored in the custom header field. In this case, the major version information indicates the structural stability of the API as a whole, while the minor versions indicate smaller changes at the implementation level.

To summarize the discussion, there is no wrong and right approach for versioning APIs. You can choose one of the options that we have discussed here for your application as long as it meets your application's needs.
