Create a user object.
What is a user?
A BILL organization user can perform operations depending on their user role profile (Administrator, Accountant, Approver, Clerk, Payer, Custom).
You can create a new user object with /Crud/Create/User.json. The user role profileId is required for creating and managing users. Retrieve id values for all user role profiles with /List/Profile.json.
