How to Retrieve Gift Certificate Internal IDs from NetSuite Web Store Transactions

While certain line item values like 'giftcertredemption' and 'authcode_display' may be accessible via the NetSuite UI, their direct availability or population within the web store context can vary or be limited. The 'authcode' line item value, however, is a consistent identifier for gift certificates, accessible through both the web store and NetSuite UI. This value can be used to identify the Gift Certificate's internal ID, which then allows for obtaining the authentication code display and performing further validations using SuiteScript 2.x methods. For example, to look up fields based on the Gift Certificate internal ID, the following SuiteScript 2.x approach can be used:

javascript
var giftCertInternalId = authcodeLineItemValue; // Assuming 'authcodeLineItemValue' is retrieved from the transaction line item
var giftCertFields = N/search.lookupFields({
    type: N/record.Type.GIFTCERTIFICATE,
    id: giftCertInternalId,
    columns: ['authcode'] // 'authcode' here refers to the field on the Gift Certificate record for its display value
});
var authCodeDisplay = giftCertFields.authcode;
