When we release backward incompatible features, we release a new dated version of our API. We configure versions for each individual API user, so when you're ready to upgrade to a new version, let us know.
You can tell which API version you're on by looking at the
response header of any authenticated request you send:
curl --head "https://app.herondata.io/api/hello_world/authenticated" --user "<your-authorisation>" ... Api-Version: 2021-04-01 ...
