The documentation says:
In addition, the Oracle, MySQL, and DB2 implementations support versioning to some level, in that it keeps older versions. However this is not visible at the level of the REST API. If all you need is keep older versions in the database, what the Oracle, MySQL, and DB2 implementation does might be sufficient. The best will be for Form Runner and Form Builder to handle versioning natively.
Does this mean we can't see form versions at all in the REST API?
Also, I would like to access the USERNAME of the form data owner via the REST API.
