A user is an individual’s login to iPaaS.com
In order for them to access pieces of the platform, they need to be assigned to a role.
If a user is deleted you can not undo this action but recreating the user with the same email address will re-enable it.
A role is a grouping of permissions
Permissions are grouped by section of the site, and for each permission, you can have rights to view, create, edit, delete or administer.
You might have a role that is able to view items in iPaaS but not edit or delete them. You also might have a role that can only view and troubleshoot errors.
If a role is deleted it can not be recovered.
