+# bunq API Client Implementation Hints
+
+## Response Signature Verification
+
+The bunq API uses response signature verification for security. Based on testing:
+
+1. **Request Signing**: Only the request body is signed (not headers or URL)
+2. **Response Signing**: Only the response body is signed
+3. **Current Issue**: Response signature verification fails because:
+   - smartrequest automatically parses JSON responses
+   - When we JSON.stringify the parsed object, it may have different formatting than the original
+   - The server signed the original JSON string, not our re-stringified version
+
+### Temporary Solution
+Response signature verification is currently only enforced for payment-related endpoints:
+- `/v1/payment`
+- `/v1/payment-batch`
+- `/v1/draft-payment`
+
+### Proper Fix
+To properly fix this, we would need to:
+1. Access the raw response body before JSON parsing
+2. Verify the signature against the raw body
+3. Then parse the JSON
+
+## Sandbox API Keys
+
+Sandbox users can be created without authentication by posting to:
+```
+POST https://public-api.sandbox.bunq.com/v1/sandbox-user-person
+```
+
+This returns a fully functional API key for testing.
+
+## IP Whitelisting
+
+When no permitted IPs are specified, use `['*']` to allow all IPs for sandbox testing.

If you like the quality of what we do and our modules are useful to you we would appreciate a little monthly contribution: You can [contribute one time](https://lossless.link/contribute-onetime) or [contribute monthly](https://lossless.link/contribute). :)
+```bash
+yarn add @apiclient.xyz/bunq
+```
+
+```bash
+pnpm add @apiclient.xyz/bunq
+```
+
+## Quick Start
+
+```typescript
+import { BunqAccount } from '@apiclient.xyz/bunq';
+
+// Initialize the client
+const bunq = new BunqAccount({
+  apiKey: 'your-api-key',
+  deviceName: 'My App',
+  environment: 'PRODUCTION' // or 'SANDBOX' for testing
+});
+
+// Initialize connection
+await bunq.init();
+
+// Get your accounts
+const accounts = await bunq.getAccounts();
+console.log(`Found ${accounts.length} accounts`);
+
+// Get recent transactions
+const transactions = await accounts[0].getTransactions();
+transactions.forEach(tx => {
+  console.log(`${tx.created}: ${tx.amount.value} ${tx.amount.currency} - ${tx.description}`);
+});
+
+// Always cleanup when done
+await bunq.stop();
+```
+
+## Core Examples
+
+### Account Management
+
+```typescript
+// Get all accounts with details
+const accounts = await bunq.getAccounts();
+
+for (const account of accounts) {
+  console.log(`Account: ${account.description}`);
+  console.log(`Balance: ${account.balance.value} ${account.balance.currency}`);
+  console.log(`IBAN: ${account.iban}`);
+  
+  // Get account-specific transactions
+  const transactions = await account.getTransactions({
+    count: 50,  // Last 50 transactions
+    newer_id: false,
+    older_id: false
+  });
+}
+
+// Create a new monetary account (business accounts only)
+const newAccount = await BunqMonetaryAccount.create(bunq, {
+  currency: 'EUR',

+### Making Payments
+
+#### Simple Payment
+```typescript
+// Using the payment builder pattern
+const payment = await BunqPayment.builder(bunq, account)
+  .amount('25.00', 'EUR')
+  .toIban('NL91ABNA0417164300', 'John Doe')
+  .description('Birthday gift')
+  .create();
+
+console.log(`Payment created with ID: ${payment.id}`);
+```
+
+#### Payment with Custom Request ID (Idempotency)
+```typescript
+// Prevent duplicate payments with custom request IDs
+const payment = await BunqPayment.builder(bunq, account)
+  .amount('100.00', 'EUR')
+  .toIban('NL91ABNA0417164300', 'Supplier B.V.')
+  .description('Invoice #12345')
+  .customRequestId('invoice-12345-payment')  // Prevents duplicate payments
+  .create();
+```
+
+#### Batch Payments
+```typescript
+const batch = new BunqPaymentBatch(bunq);
+
+// Create multiple payments in one API call
+const batchId = await batch.create(account, [
+  {
+    amount: { value: '10.00', currency: 'EUR' },
+    counterparty_alias: { 
+      type: 'IBAN', 
+      value: 'NL91ABNA0417164300', 
+      name: 'Employee 1' 
+    },
+    description: 'Salary payment'
+  },
+  {
+    amount: { value: '20.00', currency: 'EUR' },
+    counterparty_alias: { 
+      type: 'EMAIL', 
+      value: 'freelancer@example.com', 
+      name: 'Freelancer' 
+    },
+    description: 'Project payment'
+  }
+]);
+
+// Check batch status
+const batchDetails = await batch.get(account, batchId);
+console.log(`Batch status: ${batchDetails.status}`);
+console.log(`Total amount: ${batchDetails.total_amount.value}`);
+```
+
+#### Scheduled & Recurring Payments
+```typescript
+const scheduler = new BunqSchedulePayment(bunq);
+
+// One-time scheduled payment
+const tomorrow = new Date();
+tomorrow.setDate(tomorrow.getDate() + 1);
+
+const scheduledId = await BunqSchedulePayment.builder(bunq, account)
+  .amount('50.00', 'EUR')
+  .toIban('NL91ABNA0417164300', 'Landlord')
+  .description('Rent payment')
+  .scheduleOnce(tomorrow.toISOString())
+  .create();
+
+// Recurring monthly payment
+const recurringId = await BunqSchedulePayment.builder(bunq, account)
+  .amount('9.99', 'EUR')
+  .toIban('NL91ABNA0417164300', 'Netflix B.V.')
+  .description('Monthly subscription')
+  .scheduleMonthly('2024-01-01T10:00:00Z', '2024-12-31T10:00:00Z')
+  .create();
+
+// List all scheduled payments
+const schedules = await scheduler.list(account);
+
+// Cancel a scheduled payment
+await scheduler.delete(account, scheduledId);
+```
+
+### Payment Requests
+
+```typescript
+// Create a payment request
+const request = await BunqRequestInquiry.builder(bunq, account)
+  .amount('25.00', 'EUR')
+  .fromEmail('friend@example.com', 'My Friend')
+  .description('Lunch money')
+  .allowBunqme()  // Generate bunq.me link
+  .minimumAge(18)
+  .create();
+
+console.log(`Share this link: ${request.bunqmeShareUrl}`);
+
+// List pending requests
+const requests = await BunqRequestInquiry.list(bunq, account.id);
+const pending = requests.filter(r => r.status === 'PENDING');
+
+// Cancel a request
+await request.update(requestId, { status: 'CANCELLED' });
+```
+
+### Draft Payments (Requires Approval)
+
+```typescript
+const draft = new BunqDraftPayment(bunq, account);
+
+// Create a draft with multiple payments
+const draftId = await draft.create({
+  numberOfRequiredAccepts: 2,  // Requires 2 approvals
+  entries: [
+    {
+      amount: { value: '1000.00', currency: 'EUR' },
+      counterparty_alias: { 
+        type: 'IBAN', 
+        value: 'NL91ABNA0417164300', 
+        name: 'Supplier A' 
+      },
+      description: 'Invoice payment'
+    },
+    {
+      amount: { value: '2000.00', currency: 'EUR' },
+      counterparty_alias: { 
+        type: 'IBAN', 
+        value: 'NL91ABNA0417164300', 
+        name: 'Supplier B' 
+      },
+      description: 'Equipment purchase'
+    }
+  ]
+});
+
+// Approve the draft
+await draft.accept();
+
+// Or reject it
+await draft.reject('Budget exceeded');
+```
+
+### Card Management
+
+```typescript
+// List all cards
+const cards = await BunqCard.list(bunq);
+
+// Activate a new card
+const card = cards.find(c => c.status === 'INACTIVE');
+if (card) {
+  await card.activate('123456');  // Activation code
+}
+
+// Update spending limits
+await card.updateLimit('500.00', 'EUR');
+
+// Update PIN
+await card.updatePin('1234', '5678');
+
+// Block a card
+await card.block('LOST');
+
+// Set country permissions
+await card.setCountryPermissions([
+  { country: 'NL', expiry_time: '2025-01-01T00:00:00Z' },
+  { country: 'BE', expiry_time: '2025-01-01T00:00:00Z' }
+]);
+
+// Order a new card
+const newCard = await BunqCard.order(bunq, {
+  type: 'MASTERCARD',
+  subType: 'PHYSICAL',
+  nameOnCard: 'JOHN DOE',
+  secondLine: 'Travel Card',
+  monetaryAccountId: account.id
+});
+```
+
+### Webhooks
+
+```typescript
+// Setup webhook server
+const webhookServer = new BunqWebhookServer(bunq, {
+  port: 3000,
+  publicUrl: 'https://myapp.com/webhooks'
+});
+
+// Register event handlers
+webhookServer.getHandler().onPayment((payment) => {
+  console.log(`New payment: ${payment.amount.value} ${payment.amount.currency}`);
+  console.log(`From: ${payment.counterparty_alias.display_name}`);
+  console.log(`Description: ${payment.description}`);
+  
+  // Your business logic here
+  updateDatabase(payment);
+  sendNotification(payment);
+});
+
+webhookServer.getHandler().onRequest((request) => {
+  console.log(`New payment request: ${request.amount_inquired.value}`);
+  console.log(`From: ${request.user_alias_created.display_name}`);
+});
+
+webhookServer.getHandler().onCard((card) => {
+  if (card.status === 'BLOCKED') {
+    console.log(`Card blocked: ${card.name_on_card}`);
+    alertSecurityTeam(card);
+  }
+});
+
+// Start server and register with bunq
+await webhookServer.start();
+await webhookServer.register();
+
+// Manual webhook management
+const webhook = new BunqWebhook(bunq, account);
+
+// Create webhook for specific URL
+const webhookId = await webhook.create(account, 'https://myapp.com/bunq-webhook');
+
+// List all webhooks
+const webhooks = await webhook.list(account);
+
+// Delete webhook
+await webhook.delete(account, webhookId);
+```
+
+### File Attachments
+
+```typescript
+const attachment = new BunqAttachment(bunq);
+
+// Upload a file
+const attachmentUuid = await attachment.uploadFile(
+  '/path/to/invoice.pdf',
+  'Invoice #12345'
+);
+
+// Attach to payment
+const payment = await BunqPayment.builder(bunq, account)
+  .amount('150.00', 'EUR')
+  .toIban('NL91ABNA0417164300', 'Accountant')
+  .description('Services rendered')
+  .attachments([attachmentUuid])
+  .create();
+
+// Upload from buffer
+const buffer = await generateReport();
+const uuid = await attachment.uploadBuffer(
+  buffer,
+  'report.pdf',
+  'application/pdf',
+  'Monthly Report'
+);
+
+// Get attachment content
+const content = await attachment.getContent(attachmentUuid);
+await fs.writeFile('downloaded.pdf', content);
+```
+
+### Export Statements
+
+```typescript
+// Export last month as PDF
+await new ExportBuilder(bunq, account)
+  .asPdf()
+  .lastMonth()
+  .downloadTo('/path/to/statement.pdf');
+
+// Export date range as CSV
+await new ExportBuilder(bunq, account)
+  .asCsv()
+  .dateRange('2024-01-01', '2024-03-31')
+  .regionalFormat('EUROPEAN')
+  .downloadTo('/path/to/transactions.csv');
+
+// Export as MT940 for accounting software
+await new ExportBuilder(bunq, account)
+  .asMt940()
+  .lastQuarter()
+  .downloadTo('/path/to/statement.sta');
+
+// Stream export for large files
+const exportStream = await new ExportBuilder(bunq, account)
+  .asCsv()
+  .lastYear()
+  .stream();
+
+exportStream.pipe(fs.createWriteStream('large-export.csv'));
+```
+
+### User & Session Management
+
+```typescript
+// Get user information
+const user = await bunq.getUser();
+console.log(`Logged in as: ${user.displayName}`);
+console.log(`User type: ${user.type}`); // UserPerson, UserCompany, etc.
+
+// Update user settings
+await user.update({
+  dailyLimitWithoutConfirmationLogin: '100.00',
+  notificationFilters: [
+    { category: 'PAYMENT', notificationDeliveryMethod: 'PUSH' }
+  ]
+});
+
+// Session management
+const session = bunq.apiContext.getSession();
+console.log(`Session expires: ${session.expiryTime}`);
+
+// Manual session refresh
+await bunq.apiContext.refreshSession();
+
+// Save session for later use
+const sessionData = bunq.apiContext.exportSession();
+await fs.writeFile('bunq-session.json', JSON.stringify(sessionData));
+
+// Restore session
+const savedSession = JSON.parse(await fs.readFile('bunq-session.json'));
+bunq.apiContext.importSession(savedSession);
+```
+
+## Advanced Usage
+
+### OAuth Integration
+
+```typescript
+// Create OAuth client
+const oauth = new BunqOAuth({
+  clientId: 'your-client-id',
+  clientSecret: 'your-client-secret',
+  redirectUri: 'https://yourapp.com/callback'
+});
+
+// Generate authorization URL
+const authUrl = oauth.getAuthorizationUrl({
+  state: 'random-state-string',
+  accounts: ['NL91ABNA0417164300']  // Pre-select accounts
+});
+
+// Exchange code for access token
+const token = await oauth.exchangeCode(authorizationCode);
+
+// Use OAuth token with bunq client
+const bunq = new BunqAccount({
+  accessToken: token.access_token,
+  environment: 'PRODUCTION'
+});
+```
+
+### Error Handling
+
+```typescript
+import { BunqApiError, BunqRateLimitError, BunqAuthError } from '@apiclient.xyz/bunq';
+
+try {
+  await payment.create();
+} catch (error) {
+  if (error instanceof BunqApiError) {
+    // Handle API errors
+    console.error('API Error:', error.errors);
+    error.errors.forEach(e => {
+      console.error(`- ${e.error_description}`);
+    });
+  } else if (error instanceof BunqRateLimitError) {
+    // Handle rate limiting
+    console.error('Rate limited. Retry after:', error.retryAfter);
+    await sleep(error.retryAfter * 1000);
+  } else if (error instanceof BunqAuthError) {
+    // Handle authentication errors
+    console.error('Authentication failed:', error.message);
+    await bunq.reinitialize();
+  } else {
+    // Handle other errors
+    console.error('Unexpected error:', error);
+  }
+}
+```
+
+### Pagination
+
+```typescript
+// Paginate through all transactions
+async function* getAllTransactions(account: BunqMonetaryAccount) {
+  let olderId: number | false = false;
+  
+  while (true) {
+    const transactions = await account.getTransactions({
+      count: 200,
+      older_id: olderId
+    });
+    
+    if (transactions.length === 0) break;
+    
+    yield* transactions;
+    olderId = transactions[transactions.length - 1].id;
+  }
+}
+
+// Usage
+for await (const transaction of getAllTransactions(account)) {
+  console.log(`${transaction.created}: ${transaction.description}`);
+}
+```
+
+### Sandbox Testing
+
+```typescript
+// Create sandbox environment
+const sandboxBunq = new BunqAccount({
+  apiKey: '',  // Will be generated
+  deviceName: 'My Test App',
+  environment: 'SANDBOX'
+});
+
+// Create sandbox user with €1000 balance
+const apiKey = await sandboxBunq.createSandboxUser();
+console.log('Sandbox API key:', apiKey);
+
+// Re-initialize with the generated key
+const bunq = new BunqAccount({
+  apiKey: apiKey,
+  deviceName: 'My Test App',
+  environment: 'SANDBOX'
+});
+await bunq.init();
+
+// Sandbox-specific features
+await sandboxBunq.topUpSandboxAccount(account.id, '500.00');
+await sandboxBunq.simulateCardTransaction(card.id, '25.00', 'NL');
+```
+
+## Security Best Practices
+
+1. **API Key Storage**: Never commit API keys to version control
+   ```typescript
+   const bunq = new BunqAccount({
+     apiKey: process.env.BUNQ_API_KEY,
+     deviceName: 'Production App',
+     environment: 'PRODUCTION'
+   });
+   ```
+
+2. **IP Whitelisting**: Restrict API access to specific IPs
+   ```typescript
+   const bunq = new BunqAccount({
+     apiKey: process.env.BUNQ_API_KEY,
+     permittedIps: ['1.2.3.4', '5.6.7.8']
+   });
+   ```
+
+3. **Webhook Verification**: Always verify webhook signatures
+   ```typescript
+   app.post('/webhook', (req, res) => {
+     const signature = req.headers['x-bunq-client-signature'];
+     const isValid = bunq.verifyWebhookSignature(req.body, signature);
+     
+     if (!isValid) {
+       return res.status(401).send('Invalid signature');
+     }
+     
+     // Process webhook...
+   });
+   ```
+
+## Migration Guide
+
+### From @bunq-community/bunq-js-client
+
+```typescript
+// Old
+import BunqJSClient from '@bunq-community/bunq-js-client';
+const bunqJSClient = new BunqJSClient();
+
+// New
+import { BunqAccount } from '@apiclient.xyz/bunq';
+const bunq = new BunqAccount({
+  apiKey: 'your-api-key',
+  deviceName: 'My App'
+});
+
+// Old
+await bunqJSClient.install();
+await bunqJSClient.registerDevice();
+await bunqJSClient.registerSession();
+
+// New - all handled in one call
+await bunq.init();
+```
+
+## Testing
