API v2 Demo Portal OpenAPI v2 specification

Please consider that API /v2/ is now the preferred version to be used. The old API will remain fully functional until July 1, 2023.

We’re aimed to give our existing customers enough time to switch to the new API version and will notify them in advance once we know the exact deprecation date for the old API.
