It is important that you consider the lifecycle of an API. This will involve deprecation and incremental deployment of endpoint upgrades. This will ultimately mean that you will need to keep legacy endpoints alive at the same time as newer ones.
To do this, the standard is to apply a version number to the URL, for example:
When you deign youe resources in OpenAPI and create your resources in ApiOpenStudio, you should remember to prefix each resource with a version tag, which will make finding them in the Admin GUI easy, along with deprecation, tracking, etc.
