Group creation is available to org administrators from within Manager.
See User and Group APIs for information creating groups programmatically.
To create a group:
The Group name may contain UTF-8 alphanumeric characters, space, and dash "-" only, and other the punctuation characters such as !"#$%&'()*+,.:;<=>?@[]^_`{|}~ are not supported. |
The group will be added to the current organization you are logged in under. Groups cannot be shared across organizations.
When modifying the permissions of a project, you can add groups as well as individual users.
