POST, PUT, or PATCH when adding an address to a subcustomer that has no address?

AI generated answer (using internal Slack threads):

When adding an address to a subcustomer that has no address, you would typically use a POST method if you are creating a new record. However, in the context of NetSuite, you would use the SuiteScript API to add an address to a subcustomer. Here is a sample code snippet based on the conversations:

javascript
var customerRec = record.load({
    type: record.Type.CUSTOMER,
    id: 'yourCustomerId'
});

var myaddressSubrecord = customerRec.getCurrentSublistSubrecord({
    sublistId : "addressbook",
    fieldId : "addressbookaddress"
});

// Set the address fields
myaddressSubrecord.setValue({
    fieldId: 'addr1',
    value: '123 Main St'
});
myaddressSubrecord.setValue({
    fieldId: 'city',
    value: 'Anytown'
});
myaddressSubrecord.setValue({
    fieldId: 'state',
    value: 'CA'
});
myaddressSubrecord.setValue({
    fieldId: 'zip',
    value: '98765'
});

// Commit the changes
customerRec.commitLine({
    sublistId: 'addressbook'
});

// Save the record
var customerId = customerRec.save();
