## Step 3: Attribute Mapping

From your application, click the **Parameters** tab on the left.

You have to configure the following attributes:

| SAML Custom Connector Field | Value      |
| --------------------------- | ---------- |
| id                          | UUID       |
| email                       | Email      |
| firstName                   | First Name |
| lastName                    | Last Name  |

See the below screenshot to see how to map the **id** attribute to **UUID**.

Enter **id** in the **Field name** input and check the **Include in SAML assertion** checkbox. Click **Save** to continue.
