When you log in to the Provider Network, you will see that you have options to add both Contacts and Users. The Contacts listed, including their name, role, email, and phone number, will be shown to agencies. Agencies may add any Contact to a case, but this does not necessarily give these contacts access to your Provider Network system.
Users are people you have added who will be logging into your Provider Network system. You can connect Users and Contacts. In that case, when a contact has an attached user, that user will be automatically added to the case at the same time as its contact. A Manager User can also manually connect a User with a case.
