Don't get the completed shipping contact after authorizaiton

We have get the response from Apple pay after the the customer doing the face ID & touch ID authorization. But the shiping contact is not complete, for examble:

` {
        "addressLines": [
            "1************ kwy"
        ],
        "administrativeArea": "FL",
        "country": "",
        "countryCode": "",
        "emailAddress": "S*********le.com",
        "familyName": "******i",
        "givenName": "******m",
        "locality": "*******s",
        "phoneNumber": "+*******79",
        "phoneticFamilyName": "",
        "phoneticGivenName": "",
        "postalCode": "*****3",
        "subAdministrativeArea": "",
        "subLocality": ""
    },`
