Migration Guide

const response = await fetch(`/wallets/${walletId}/virtual-accounts`);
const account = await response.json();

console.log(account.accountNumber);
console.log(account.bankName);

const response = await fetch(`/wallets/${walletId}/virtual-accounts`);
const { data, meta } = await response.json();

// Handle empty array case
if (data.length === 0) {
  console.log('No virtual accounts found');
  return;
}

// Get the first account (equivalent to old behavior)
const account = data[0];
console.log(account.accountNumber);
console.log(account.bankName);

// Or iterate through all accounts
for (const account of data) {
  console.log(account.accountNumber);
}

// Pagination info available in meta
console.log(`Page ${meta.currentPage} of ${meta.totalPages}`);

const response = await fetch(`/wallets/${walletId}/virtual-accounts/${virtualAccountId}`);

if (!response.ok) {
  console.log('Virtual account not found');
  return;
}

const { data } = await response.json();
console.log(data.accountNumber);
