Hello there,

I want to validate phone number field based on Lookup Api JSON response. I have used the below code but this is not working. Anyone can help me to work it?

window.ub.form.customValidators.usPhoneNumber = {

    isValid: function(value) {

    var country_code;

    var uName="API Key SID";

    var passwrd="API Key Secret";

    var apiUrl = 'https://lookups.twilio.com/v1/PhoneNumbers/'+value;

    var auth = btoa(uName+":"+passwrd);

    $.ajax({

    type: 'GET',

    url: apiUrl,

    headers: {

      "Authorization": "Basic " + auth

    },

    success : function(data) {

      country_code = data.country_code;

      console.log(country_code);

    },

  });

  return country_code === 'US';

},

message: 'Please enter a valid US Phone Number',

};

window.ub.form.validationRules.cellphone_number.usPhoneNumber = true;
