Getting Started

import { WaveClient } from 'wave-api-client';

// Initialize the client with your API key
const waveClient = new WaveClient({
  apiKey: 'wave_sn_prod_xxxx', // Replace with your API key

• Checkout API
• Payout API
• Merchants API

Balance & Reconciliation API

// Get current wallet balance
const balance = await waveClient.balance.getBalance();

// Get balance with optional parameters
const balanceWithSubaccounts = await waveClient.balance.getBalance({
  include_subaccounts: true
});

// List transactions
const transactions = await waveClient.balance.listTransactions({
  date: '2023-01-01',
  after: 'cursor_token',
  include_subaccounts: true
});

// Refund a transaction
await waveClient.balance.refundTransaction('transaction_id');
Copy

Checkout API

// Create a checkout session
const session = await waveClient.checkout.createSession({
  amount: '1000',
  currency: 'XOF',
  success_url: 'https://example.com/success',
  error_url: 'https://example.com/error',
  // Optional parameters
  cancel_url: 'https://example.com/cancel',
  client_reference: 'order_12345',
  aggregated_merchant_id: 'merchant_123',
  restrict_payer_mobile: '+221700000000'
});

// Get session details
const sessionDetails = await waveClient.checkout.getSession('session_123');

// Get session by transaction ID
const sessionByTx = await waveClient.checkout.getSessionByTransactionId('transaction_123');

// Search sessions by client reference
const sessions = await waveClient.checkout.searchSessions('order_12345');

// Refund a session
await waveClient.checkout.refundSession('session_123');

// Expire a session
await waveClient.checkout.expireSession('session_123');
Copy

// Send a single payout (requires an idempotency key)
const payout = await waveClient.payout.createPayout({
  receive_amount: '5000',
  currency: 'XOF',

  name: 'John Doe',
  // Optional parameters

// Create a batch of payouts
const batch = await waveClient.payout.createPayoutBatch({
  payouts: [
    {
      receive_amount: '5000',
      currency: 'XOF',
      mobile: '+221700000000',
      name: 'John Doe',

      name: 'Jane Smith',
      client_reference: 'payment_12346'
    },
  ]
}, 'batch-idempotency-key-123');

// Get payout details
const payoutDetails = await waveClient.payout.getPayout('payout_123');

// Get batch details
const batchDetails = await waveClient.payout.getPayoutBatch('batch_123');

// Search payouts by client reference
const payouts = await waveClient.payout.searchPayouts('payment_12345');

// Reverse a payout
await waveClient.payout.reversePayout('payout_123');
Copy

Merchants API

// List merchants
const merchants = await waveClient.merchants.listMerchants();

// List merchants with filters
const filteredMerchants = await waveClient.merchants.listMerchants({
  status: 'active',

Error Handling

The client provides detailed error information with proper typing:

import { WaveApiError, ValidationError } from 'wave-api-client';

try {
  await waveClient.checkout.createSession({
    // Invalid request
  });
} catch (error) {
  if (error instanceof ValidationError) {
    console.error('Validation error:', error.message, error.details);
  } else if (error instanceof WaveApiError) {
    console.error(`API error (${error.statusCode}):`, error.message);
  } else {
    console.error('Unexpected error:', error);
  }
