Web Services API Versioning

Question

I offer a small Web Services API to my clients which I plan to evolve over time. So I need some sort of versioning, but I can\'t find any information about how you do someth

Answer 1

I generally add the version string to the web service URL, giving me "versioned endpoints". The code implementing those endpoints can either be shared, if the differences are trivial and can be handled by the same code, or the code can be cloned, or somewhere in between.

The different versioned endpoints could also use versioned XML Schemas, if that's what you need.
