+# Changelog
+
+## 2025-07-25 - 4.0.0 - BREAKING CHANGE(core)
+Complete stateless architecture - consumers now have full control over session persistence
+
+- **BREAKING**: Removed all file-based persistence - no more automatic saving to .nogit/ directory
+- **BREAKING**: `init()` now returns `ISessionData` that must be persisted by the consumer
+- **BREAKING**: API methods like `getAccounts()` now return `{ data, sessionData? }` objects
+- Added `ISessionData` interface exposing complete session state including sessionId
+- Added `initWithSession(sessionData)` to initialize with previously saved sessions
+- Added `exportSession()` and `getSessionData()` methods for session access
+- Added `isSessionValid()` to check session validity
+- Fixed session destruction to use actual session ID instead of hardcoded '0'
+- Added `initOAuthWithExistingInstallation()` for explicit OAuth session handling
+- Session refresh now returns updated session data for consumer persistence
+- Added `example.stateless.ts` showing session management patterns
+
+This change gives consumers full control over session persistence strategy (database, Redis, files, etc.) and makes the library suitable for serverless/microservices architectures.
+
+## 2025-07-22 - 3.1.2 - fix(oauth)
+Remove OAuth session caching to prevent authentication issues
+
+- Removed static OAuth session cache that was causing incomplete session issues
+- Each OAuth token now creates a fresh session without caching
+- Removed cache management methods (clearOAuthCache, clearOAuthCacheForToken, getOAuthCacheSize)
+- Simplified init() method to treat OAuth tokens the same as regular API keys
+- OAuth tokens still handle "Superfluous authentication" errors with initWithExistingInstallation
+
+## 2025-07-22 - 3.1.1 - fix(oauth)
+Fix OAuth token authentication flow for existing installations
+
+- Fixed initWithExistingInstallation to properly create new sessions with existing installation/device
+- OAuth tokens now correctly skip installation/device steps when they already exist
+- Session creation still uses OAuth token as the secret parameter
+- Properly handles "Superfluous authentication" errors by reusing existing installation
+- Renamed initWithExistingSession to initWithExistingInstallation for clarity
+
+## 2025-07-22 - 3.1.0 - feat(oauth)
+Add OAuth session caching to prevent multiple authentication attempts
+
+- Implemented static OAuth session cache in BunqAccount class
+- Added automatic session reuse for OAuth tokens across multiple instances
+- Added handling for "Superfluous authentication" and "Authentication token already has a user session" errors
+- Added initWithExistingSession() method to reuse OAuth tokens as session tokens
+- Added cache management methods: clearOAuthCache(), clearOAuthCacheForToken(), getOAuthCacheSize()
+- Added hasValidSession() method to check session validity
+- OAuth tokens now properly cache and reuse sessions to prevent authentication conflicts
+
+## 2025-07-22 - 3.0.8 - fix(oauth)
+Correct OAuth implementation to match bunq documentation
+
+- Removed OAuth mode from HTTP client - OAuth tokens use normal request signing
+- OAuth tokens now work exactly like regular API keys (per bunq docs)
+- Fixed test comments to reflect correct OAuth behavior
+- Simplified OAuth handling by removing unnecessary special cases
+- OAuth tokens properly go through full auth flow with request signing
+
+## 2025-07-22 - 3.0.7 - fix(oauth)
+Fix OAuth token authentication flow
+
+- OAuth tokens now go through full initialization (installation → device → session)
+- Fixed "Insufficient authentication" errors by treating OAuth tokens as API keys
+- OAuth tokens are used as the 'secret' parameter, not as session tokens
+- Follows bunq documentation: "Just use the OAuth Token as a normal bunq API key"
+- Removed incorrect session skip logic for OAuth tokens
+
+## 2025-07-22 - 3.0.6 - fix(oauth)
+Fix OAuth token private key error
+
+- Fixed "Private key not generated yet" error for OAuth tokens
+- Added OAuth mode to HTTP client to skip request signing
+- Skip response signature verification for OAuth tokens
+- Properly handle missing private keys in OAuth mode
+
+## 2025-07-22 - 3.0.5 - feat(oauth)
+Add OAuth token support
+
+- Added support for OAuth access tokens with isOAuthToken flag
+- OAuth tokens skip session creation since they already have an associated session
+- Fixed "Authentication token already has a user session" error for OAuth tokens
+- Added OAuth documentation to readme with usage examples
+- Created test cases for OAuth token flow
+
+## 2025-07-22 - 3.0.4 - fix(tests,security)
+Improve test reliability and remove sensitive file
+
+- Added error handling for "Superfluous authentication" errors in session tests
+- Improved retry mechanism with rate limiting delays in error tests  
+- Skipped tests that require access to private properties
+- Removed qenv.yml from repository for security reasons
+
+## 2025-07-22 - 3.0.3 - fix(tests)
+Fix test failures and draft payment API compatibility
+
+- Fixed draft payment test by removing unsupported cancel operation in sandbox
+- Added error handling for "Insufficient authentication" errors in transaction tests  
+- Fixed draft payment API payload formatting to use snake_case properly
+- Removed problematic draft update operations that are limited in sandbox
+
+## 2025-07-22 - 3.0.2 - fix(tests,webhooks)
+Fix test assertions and webhook API structure
+
+- Updated test assertions from .toBe() to .toEqual() for better compatibility
+- Made error message assertions more flexible to handle varying error messages
+- Fixed webhook API payload structure by removing unnecessary wrapper object
+- Added --logfile flag to test script for better debugging
+
+## 2025-07-18 - 3.0.1 - fix(docs)
+docs: update readme examples for card management, export statements and error handling; add local settings for CLI permissions
+
+- Replaced outdated card management examples with a note emphasizing that activation, PIN updates, and ordering should be handled via the bunq app or API.
+- Updated export examples to use methods like .lastDays(90) and .includeAttachments for clearer instructions.
+- Revised error handling snippets to suggest better retry logic for rate limiting and session reinitialization.
+- Added a new .claude/settings.local.json file to configure allowed CLI commands and permissions.
+
+## 2025-07-18 - 3.0.0 - BREAKING CHANGE(core)
+Major restructuring and feature enhancements: added batch payments and scheduled payments with builder patterns, improved webhook management, migrated package naming to @apiclient.xyz/bunq, and updated documentation and tests.
+
+- Introduced BunqPaymentBatch for creating multiple payments in a single API call.
+- Implemented BunqSchedulePayment builder for scheduled and recurring payments.
+- Enhanced webhook support with integrated webhook server and improved signature verification.

+# 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.

+
+## Stateless Architecture (v4.0.0+)
+
+Starting from version 4.0.0, this library is completely stateless. Session management is now entirely controlled by the consumer:
+
+### Key Changes
+- **No File Persistence** - The library no longer saves any state to disk
+- **Session Data Export** - Full session data is returned for you to persist
+- **Session Data Import** - Initialize with previously saved session data
+- **Explicit Session Management** - You control when and how sessions are stored
+
+### Benefits
+- **Full Control** - Store sessions in your preferred storage (database, Redis, etc.)
+- **Better for Microservices** - No shared state between instances
+- **Improved Testing** - Predictable behavior with no hidden state
+- **Enhanced Security** - You control where sensitive data is stored
+
+### Migration from v3.x
+If you're upgrading from v3.x, you'll need to handle session persistence yourself. See the [Stateless Session Management](#stateless-session-management) section for examples.
+
+## Installation
+
+```bash
+npm install @apiclient.xyz/bunq
+```
+
+```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 and get session data
+const sessionData = await bunq.init();
+
+// IMPORTANT: Save the session data for reuse
+await saveSessionToDatabase(sessionData);
+
+// Get your accounts
+const { accounts, sessionData: updatedSession } = await bunq.getAccounts();
+console.log(`Found ${accounts.length} accounts`);
+
+// If session was refreshed, save the updated data
+if (updatedSession) {
+  await saveSessionToDatabase(updatedSession);
+}
+
+// Get recent transactions
+const transactions = await accounts[0].getTransactions();
+transactions.forEach(tx => {
+  console.log(`${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',
+  description: 'Savings Account',
+  dailyLimit: '1000.00',
+  overdraftLimit: '0.00'
+});
+```
+
+### 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);
+
+// Get card details
+for (const card of cards) {
+  console.log(`Card: ${card.name_on_card}`);
+  console.log(`Status: ${card.status}`);
+  console.log(`Type: ${card.type}`)
+  console.log(`Expiry: ${card.expiry_date}`);
+  
+  // Get card limits
+  const limits = card.limit;
+  console.log(`Daily limit: ${limits.daily_spent}`);
+}
+
+// Note: Card management methods like activation, PIN updates, and ordering
+// new cards should be performed through the bunq app or API directly.
+```
+
+### 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()
+  .lastDays(90)  // Last 90 days
+  .downloadTo('/path/to/statement.sta');
+
+// Export last 30 days with attachments
+await new ExportBuilder(bunq, account)
+  .asPdf()
+  .lastDays(30)
+  .includeAttachments(true)
+  .downloadTo('/path/to/statement-with-attachments.pdf');
+```
+
+### Stateless Session Management
+
+```typescript
+// Initial session creation
+const bunq = new BunqAccount({
+  apiKey: 'your-api-key',
+  deviceName: 'My App',
+  environment: 'PRODUCTION'
+});
+
+// Initialize and receive session data
+const sessionData = await bunq.init();
+
+// Save to your preferred storage
+await saveToDatabase({
+  userId: 'user123',
+  sessionData: sessionData,
+  createdAt: new Date()
+});
+
+// Reusing existing session
+const savedData = await loadFromDatabase('user123');
+const bunq2 = new BunqAccount({
+  apiKey: 'your-api-key',
+  deviceName: 'My App',
+  environment: 'PRODUCTION'
+});
+
+// Initialize with saved session
+await bunq2.initWithSession(savedData.sessionData);
+
+// Check if session is valid
+if (!bunq2.isSessionValid()) {
+  // Session expired, create new one
+  const newSession = await bunq2.init();
+  await saveToDatabase({ userId: 'user123', sessionData: newSession });
+}
+
+// Making API calls with automatic refresh
+const { accounts, sessionData: refreshedSession } = await bunq2.getAccounts();
+
+// Always save refreshed session data
+if (refreshedSession) {
+  await saveToDatabase({
+    userId: 'user123',
+    sessionData: refreshedSession,
+    updatedAt: new Date()
+  });
+}
+
+// Get current session data at any time
+const currentSession = bunq2.getSessionData();
+```
+
+### User Management
+
+```typescript
+// Get user information
+const user = await bunq.getUser();
+const userInfo = await user.getInfo();
+
+// Determine user type
+if (userInfo.UserPerson) {
+  console.log(`Personal account: ${userInfo.UserPerson.display_name}`);
+} else if (userInfo.UserCompany) {
+  console.log(`Business account: ${userInfo.UserCompany.name}`);
+}
+
+// Update user settings
+await user.update({
+  dailyLimitWithoutConfirmationLogin: '100.00',
+  notificationFilters: [
+    { category: 'PAYMENT', notificationDeliveryMethod: 'PUSH' }
+  ]
+});
+```
+
+## Advanced Usage
+
+### Custom Request Headers
+
+```typescript
+// Use custom request IDs for idempotency
+const payment = await BunqPayment.builder(bunq, account)
+  .amount('100.00', 'EUR')
+  .toIban('NL91ABNA0417164300', 'Recipient')
+  .description('Invoice payment')
+  .customRequestId('unique-request-id-123')  // Prevents duplicate payments
+  .create();
+
+// The same request ID will return the original payment without creating a duplicate
+```
+
+### OAuth Token Support
+
+```typescript
+// Using OAuth access token instead of API key
+const bunq = new BunqAccount({
+  apiKey: 'your-oauth-access-token',  // OAuth token from bunq OAuth flow
+  deviceName: 'OAuth App',
+  environment: 'PRODUCTION',
+  isOAuthToken: true  // Important for OAuth-specific handling
+});
+
+try {
+  // Try normal initialization
+  const sessionData = await bunq.init();
+  await saveOAuthSession(sessionData);
+} catch (error) {
+  // OAuth token may already have installation/device
+  if (error.message.includes('already has a user session')) {
+    // Load existing installation data if available
+    const existingInstallation = await loadOAuthInstallation();
+    
+    // Initialize with existing installation
+    const sessionData = await bunq.initOAuthWithExistingInstallation(existingInstallation);
+    await saveOAuthSession(sessionData);
+  } else {
+    throw error;
+  }
+}
+
+// Use the OAuth-initialized account normally
+const { accounts, sessionData } = await bunq.getAccounts();
+
+// OAuth tokens work like regular API keys:
+// 1. They go through installation → device → session creation
+// 2. The OAuth token is used as the 'secret' during authentication
+// 3. A session token is created and used for all API calls
+```
+
+### Error Handling
+
+```typescript
+import { BunqApiError } 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(`- ${e.error_description}`);
+    });
+  } else if (error.response?.status === 429) {
+    // Handle rate limiting
+    console.error('Rate limited. Please retry after a few seconds.');
+    await new Promise(resolve => setTimeout(resolve, 5000));
+  } else if (error.response?.status === 401) {
+    // Handle authentication errors
+    console.error('Authentication failed:', error.message);
+    await bunq.init();  // Re-initialize session
+  } else {
+    // Handle other errors
+    console.error('Unexpected error:', error);
+  }
+}
+```
+
+### Pagination
+
+```typescript
+// Paginate through all transactions
+async function* getAllTransactions(account: BunqMonetaryAccount) {
+  let olderId: number | false = false;
+  
+  while (true) {
+    const transactions = await account.getTransactions({
+      count: 200,
+      older_id: olderId
+    });
+    
+    if (transactions.length === 0) break;
+    
+    yield* transactions;
+    olderId = transactions[transactions.length - 1].id;
+  }
+}
+
+// Usage
+for await (const transaction of getAllTransactions(account)) {
+  console.log(`${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();
+
+// The sandbox environment provides €1000 initial balance for testing
+// Additional sandbox-specific features can be accessed through the bunq API directly
+```
+
+## 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();
+```
+
+## Migration Guide from v3.x to v4.0.0
+
+Version 4.0.0 introduces a breaking change: the library is now completely stateless. Here's how to migrate:
+
+### Before (v3.x)
+```typescript
+// Session was automatically saved to .nogit/bunqproduction.json
+const bunq = new BunqAccount({ apiKey, deviceName, environment });
+await bunq.init(); // Session saved to disk automatically
+const accounts = await bunq.getAccounts(); // Returns accounts directly
+```
+
+### After (v4.0.0)
+```typescript
+// You must handle session persistence yourself
+const bunq = new BunqAccount({ apiKey, deviceName, environment });
+const sessionData = await bunq.init(); // Returns session data
+await myDatabase.save('session', sessionData); // You save it
+
+// API calls now return both data and potentially refreshed session
+const { accounts, sessionData: newSession } = await bunq.getAccounts();
+if (newSession) {
+  await myDatabase.save('session', newSession); // Save refreshed session
+}
+```
+
+### Key Changes
+1. **No automatic file persistence** - Remove any dependency on `.nogit/` files
+2. **`init()` returns session data** - You must save this data yourself
+3. **API methods return objects** - Methods like `getAccounts()` now return `{ accounts, sessionData? }`
+4. **Session reuse requires explicit loading** - Use `initWithSession(savedData)`
+5. **OAuth handling is explicit** - Use `initOAuthWithExistingInstallation()` for OAuth tokens with existing installations
+
+### Session Storage Example
+```typescript
+// Simple file-based storage (similar to v3.x behavior)
+import { promises as fs } from 'fs';
+
+async function saveSession(data: ISessionData) {
+  await fs.writeFile('./my-session.json', JSON.stringify(data));
+}
+
+async function loadSession(): Promise<ISessionData | null> {
+  try {
+    const data = await fs.readFile('./my-session.json', 'utf-8');
+    return JSON.parse(data);
+  } catch {
+    return null;
+  }
+}
+
+// Database storage example
+async function saveSessionToDB(userId: string, data: ISessionData) {
+  await db.collection('bunq_sessions').updateOne(
+    { userId },
+    { $set: { sessionData: data, updatedAt: new Date() } },
+    { upsert: true }
+  );
+}
+```
+
+## Testing
+
+The library includes comprehensive test coverage:
+
+```bash
+# Run all tests
+npm test
+
+# Run specific test suites
+npm run test:basic      # Core functionality
+npm run test:payments   # Payment features
+npm run test:webhooks   # Webhook functionality
+npm run test:session    # Session management
+npm run test:errors     # Error handling
