There is no REST API to create a Board. A create API may be included as part of the work for Flow Board import/copy operations, eg:
https://appfire.atlassian.net/browse/FB-111 "Import JSON to a single board"
https://appfire.atlassian.net/browse/FB-85 "Copy board"
Feel free to add your vote or comments to any of our Jira items for Flow Board (https://appfire.atlassian.net/wiki/spaces/SUP/pages/147358291/Vote+on+Jira+Issues)
Security
The REST APIs verify access is permitted to the resources being operated upon by the caller. Some APIs are admin-only and those are identified as such.
