Verb Data Access APIs can be versioned to help your end users keep up with schema changes at their own pace.
To create a new Version of a Data Access API Collection you will edit the current API version. When your changes are ready for production you'll publish the API. During the publish process you'll have the option to overwrite the current version or create and number the new version.
When creating a new collection version, Data Access Keys with permissions will automatically have access to the new version. Their documentation will be automatically updated and available at the same link to make it simple for your end user to see the changes. You will need to notify the end user of the new version or share the key with them again.
