input.catalogCode = "Phones"; // use your Catalog Code
input.offerCode = "iPhoneX"; // use your Offer Code

// input.offerConfiguration: use digitalCommerce.getSelectedOffer(offerCode)
input.offerConfiguration = digitalCommerce.getSelectedOffer(offerCode);
input.customFields = ["customAttribute__c"]; // optional field which returns your custom attributes or any given keys
// Invoke ConfigureOfferDetails API via method validateOffer()
digitalCommerce
  .validateOffer(input)
  .then(response => {
    Logger.info(
      "vlocity validate offer for anonymous user" + JSON.stringify(response)
