# Customers API

The Customers API allows you to view information about SAS Customers. A SAS Customer is defined
by the following parameters:

- A unique name, which is assigned by the server.
- A display name
- All of the SAS user IDs that are associated with that customer.

> [!NOTE]
> **Note:** User IDs must be unique. A given user ID can only be associated with one Customer.

The API defines methods to list the Customers visible to you or to get information about a
specific Customer.
