Code Examples

import { HedgePayments } from '@hedgepayments/sdk';

const hedge = new HedgePayments(process.env.HEDGE_API_KEY);

async function processPayment() {
  try {
    const transaction = await hedge.transactions.create({
      amount: 10000, // $100.00
      currency: 'USD',
      method: 'card',
      paymentMethodId: 'pm_card_abc123',
      description: 'Premium Subscription',
      metadata: {
        orderId: 'order_12345',
        customerId: 'cust_abc'
      },
      idempotencyKey: `payment-${Date.now()}`
    });

    if (transaction.status === 'completed') {
      console.log('Payment successful:', transaction.id);
      // Fulfill order
    } else {
      console.log('Payment pending:', transaction.status);
      // Wait for webhook
    }

    return transaction;
  } catch (error) {
    if (error.code === 'INSUFFICIENT_FUNDS') {
      console.log('Payment declined - insufficient funds');
    } else if (error.code === 'CARD_DECLINED') {
      console.log('Card declined by issuer');
    }
    throw error;
  }
}

Payment Methods Comparison

Method	Processing Time	Settlement	Fees	Reversible	Geographic
Card	Instant	T+1 to T+3	~2.9% + $0.30	Yes (chargebacks)	Global
ACH	1-3 days	T+3 to T+5	~1%	Yes (returns)	US only
Wire	1-3 days	Same day	$25 flat	No	Global
Wallet	Instant	Instant	0%	No	Global
Crypto	5-60 min	Instant	Network fees	No	Global
Apple Pay	Instant	T+1 to T+3	~2.9% + $0.30	Yes	Global
Google Pay	Instant	T+1 to T+3	~2.9% + $0.30	Yes	Global

Error Codes

Code	HTTP	Description	Action
`INSUFFICIENT_FUNDS`	402	Not enough balance	Add funds or use different payment method
`CARD_DECLINED`	402	Card issuer declined	Contact card issuer or try different card
`INVALID_PAYMENT_METHOD`	400	Payment method not valid for currency	Use supported method
`PAYMENT_METHOD_NOT_FOUND`	404	Payment method ID doesn’t exist	Verify payment method ID
`AMOUNT_TOO_SMALL`	400	Below minimum amount	Increase amount (min $0.50)
`AMOUNT_TOO_LARGE`	400	Exceeds limits	Split into multiple transactions
`DUPLICATE_TRANSACTION`	409	Idempotency key already used	Use unique key or retrieve existing
`RATE_LIMIT_EXCEEDED`	429	Too many requests	Implement backoff

Webhooks

Transaction events trigger webhooks:

{
  "event": "transaction.completed",
  "data": {
    "id": "txn_abc123",
    "amount": 10000,
    "currency": "USD",
    "status": "completed",
    "completedAt": "2025-11-18T22:30:02Z"
  }
}

Best Practices

1. Always Use Idempotency Keys

// Generate unique key per attempt
const idempotencyKey = `payment-${orderId}-${Date.now()}`;

const transaction = await hedge.transactions.create({
  amount: 10000,
  currency: 'USD',
  idempotencyKey // Prevents duplicate charges
});

2. Handle Async Payments

Some methods (ACH, wire) are asynchronous:

const transaction = await hedge.transactions.create({ ... });

if (transaction.status === 'processing') {
  // Don't fulfill order yet
  // Wait for webhook notification
  console.log('Payment pending, estimated:', transaction.estimatedCompletion);
} else if (transaction.status === 'completed') {
  // Instant payment - fulfill immediately
  fulfillOrder(orderId);
}

3. Implement Retry Logic

async function processPaymentWithRetry(data, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      return await hedge.transactions.create(data);
    } catch (error) {
      if (error.code === 'RATE_LIMIT_EXCEEDED' && i < maxRetries - 1) {
        await sleep(Math.pow(2, i) * 1000); // Exponential backoff
        continue;
      }
      throw error;
    }
  }
}
