Code Node: Normalize Data

const raw = $input.item.json;

// Normalize phone
let phone = (raw.phone || '').replace(/\D/g, '');
if (phone.startsWith('0')) phone = '62' + phone.substring(1);

// Normalize tier
const tier = (raw.tier || 'regular').toLowerCase().trim();

// Validate amount
const amount = Number(raw.amount) || 0;

// Generate order ID
const orderId = 'ORD-' + Date.now();

return {
  json: {
    orderId,
    nama: raw.nama || 'Unknown',
    email: raw.email || '',
    phone_formatted: phone,
    tier,
    amount,
    product: raw.product || '',
    source: raw.source || 'unknown',
    timestamp: new Date().toISOString()
  }
};
