On: Ask HN: Version numbers in a REST API

[shib71]

You should incorporate the API version.

  - you're developing a service would typically be a core part of your client's businesses
  - the API will almost certainly need be revised after you release it
  - even if you choose not to support deprecated versions, you will need to give your clients enough time to switch
  - that means that there will be periods where at least two versions of the API will be live
  - and both versions will need to be live on their final endpoints
