Integration Examples

REST API Integration

// Initialize the WIA-FIN-021 client
const client = new FinancialDataExchangeClient({
  apiKey: 'your-api-key',
  environment: 'production',
  security: {
    protocol: 'oauth2',
    tokenEndpoint: 'https://auth.example.com/token'
  }
});

// Fetch account data
const accounts = await client.accounts.getAll({
  customerId: 'CUST-12345',
  includeTransactions: true
});

console.log(`Retrieved ${accounts.length} accounts`);
                

WebSocket Streaming

// Connect to market data stream
const stream = client.marketData.subscribe({
  symbols: ['AAPL', 'GOOGL', 'MSFT'],
  fields: ['LAST_PRICE', 'VOLUME', 'BID', 'ASK']
});

stream.on('data', (quote) => {
  console.log(`${quote.symbol}: $${quote.lastPrice}`);
});

stream.on('error', (error) => {
  console.error('Stream error:', error);
});
                

Payment Initiation (PSD2)

// Initiate a payment
const payment = await client.payments.initiate({
  debtorAccount: 'DE89370400440532013000',
  creditorAccount: 'GB29NWBK60161331926819',
  amount: 1500.00,
  currency: 'EUR',
  remittanceInformation: 'Invoice #12345'
});

// Get consent URL for SCA
const consentUrl = payment.scaRedirectUrl;
console.log(`Redirect user to: ${consentUrl}`);

// Check payment status
const status = await client.payments.getStatus(payment.id);
console.log(`Payment status: ${status.transactionStatus}`);
