Scoped to this specific organization for a given Product, this API allows you to create custom Roles that only those in the Organization will be able to see. Be careful not to use this API when you intend to create a Global Role. If the specified product is not associated to the Organization, this returns a 404. There is a non-standard way of associating a permission to a Role. The property "permissions" takes an array of strings comprised of a concat of the Permission Ids and the Permission code. As an example, "3fa85f64-5717-4562-b3fc-2c963f66afa6 user::read:own" would be one string entry.
