The Groups APIs are part of the Security APIs.
The Security APIs, available from Artifactory release 7.49.3, replace the previous Security APIs, which are planned to be deprecated at a later stage. The new APIs address all aspects of JFrog Platform security and access.
New Security APIs
JFrog is currently exposing the new Security REST APIs that are already available; these APIs are being modified and in the coming periods will be added to and will replace the previous APIs, but will remain backward-compatible.
