By the end of this guide, you'll have everything configured to start making transfers between wallets in different currencies. + +> **Developer Insight:** "I remember staring at a blank code editor, knowing I needed to implement cross-border payments but dreading the complexity ahead. This setup guide is exactly what I wish I'd had then – a clear path from zero to your first successful API call." + +## Prerequisites + +Before you begin, make sure you have: + +- Basic understanding of APIs and HTTP requests +- A tool for making API requests (Postman, cURL, or your preferred programming language) +- A Chimoney account (don't worry, we'll cover how to create one—it takes less than 2 minutes and doesn't require a credit card for the sandbox) + +## Step 1: Create a Chimoney Account + +1. Visit [https://sandbox.chimoney.io/](https://sandbox.chimoney.io/) to create a sandbox account +2. Click "Sign Up" and complete the registration process +3. Verify your email address + +The sandbox environment comes with $1,000 of test funds automatically loaded into your account, allowing you to experiment without using real money. This means you can focus on learning and testing without the anxiety of potentially losing funds or needing approval for every test transaction. + +✓ **Achievement unlocked:** You've taken your first step toward frictionless global payments! + +## Step 2: Create an Organization + +1. Log in to your Chimoney sandbox account +2. Navigate to the "Organizations" tab in the dashboard +3. Click "Create Organization" or "Create Team" +4. Fill in the required details: + - Organization name + - Country of operation - (Full address) + - Contact information - (Email of team members) +5. Submit the form to create your organization + +Creating an organization is important as it helps organize your API keys and wallet structures, especially if you're building a platform that will handle payments for multiple users or departments. Think of it as creating a solid foundation for your payment architecture – proper organization now will save you countless headaches as your application scales. + +## Step 3: Generate Your API Key + +1. In your Chimoney dashboard, navigate to the "Developers" tab +2. Click "Create App" to generate a new API key +3. Fill in the application details: + - App name (e.g., "Payment Platform") + - Description (optional) + - Webhook URL (optional) +4. Once created, you'll see your API key displayed +5. Copy and securely store this key—you'll need it for all API requests + +> ⚠️ **Security Note**: Never expose your API key in client-side code or public repositories. Always store it securely as an environment variable or in a secure vault. Many developers have learned this lesson the hard way, with exposed keys leading to unauthorized transactions or account lockouts. + +## Step 4: Understanding the API Environment + +### Sandbox Environment + +- Base URL: `https://sandbox-api.chimoney.io/v0.2.4/` +- Use for development and testing +- Transactions don't involve real money +- Automatically funded with test money +- Perfect for integrating and testing your application + +For this guide, we'll use the sandbox environment to safely experiment with the API. The relief of knowing you can test freely without financial consequences makes the development process much more enjoyable and encourages thorough testing. + +## Step 5: Setting Up Authentication + +All requests to the Chimoney API require authentication using your API key in the request header. + +### Header Format + +``` +Authorization: Bearer YOUR_API_KEY +``` + +Replace `YOUR_API_KEY` with the key you generated in Step 3. + +### Testing Authentication + +Let's verify your API key is working by making a simple request to check your account information: + +```bash +curl -X GET https://sandbox-api.chimoney.io/v0.2.4/info/assets \ + -H "Authorization: Bearer YOUR_API_KEY" +``` + +If successful, you should receive a JSON response with a list of supported assets. + +**Developer Insight:** "The first time I saw a successful response from the API, I felt a surprising sense of relief. That green status code meant I was on the right track, and suddenly the task ahead seemed manageable." + +✓ **Achievement unlocked:** You've successfully authenticated with the Chimoney API! + +## Step 6: Create Multi-Currency Wallets + +Before you can transfer funds between currencies, you need to create wallets for each currency you want to work with. The Chimoney API currently supports USD, CAD, and NGN for multi-currency wallets. + +Imagine these wallets as specialized containers designed to hold different types of currencies – each with its own rules and characteristics, but all managed through a single unified interface. + +### Creating a USD Wallet + +```bash +curl -X POST https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/create \ + -H "Authorization: Bearer YOUR_API_KEY" \ + -H "Content-Type: application/json" \ + -d '{ + "name": "USD Wallet", + "currency": "USD" + }' +``` + +### Creating a NGN Wallet + +```bash +curl -X POST https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/create \ + -H "Authorization: Bearer YOUR_API_KEY" \ + -H "Content-Type: application/json" \ + -d '{ + "name": "NGN Wallet", + "currency": "NGN" + }' +``` + +### Creating a CAD Wallet + +```bash +curl -X POST https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/create \ + -H "Authorization: Bearer YOUR_API_KEY" \ + -H "Content-Type: application/json" \ + -d '{ + "name": "CAD Wallet", + "currency": "CAD" + }' +``` + +### Expected Response + +```json +{ + "status": "success", + "data": { + "id": "wallet_abc123", + "name": "USD Wallet", + "currency": "USD", + "balance": 0, + "createdAt": "2023-07-23T12:34:56.789Z" + } +} +``` + +Save the wallet IDs returned in the responses—you'll need them for transfers. These IDs are your digital keys to access each wallet, so keep them organized and accessible in your code. + +✓ **Achievement unlocked:** You've created multi-currency wallets that can hold different currencies! + +## Step 7: Funding Your Wallets + +In the sandbox environment, your account is automatically funded with test money. You can verify your wallet balances using: + +```bash +curl -X GET https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/list \ + -H "Authorization: Bearer YOUR_API_KEY" +``` + +This will return a list of all your wallets with their current balances. + +## Step 8: Setting Up Webhook Notifications (Recommended) + +It's recommended to set up webhooks to receive real-time notifications about transaction status changes. + +Webhooks are like having a dedicated assistant who taps you on the shoulder the moment something important happens, rather than you having to constantly check for updates. They're especially valuable for payment systems where timely information can make the difference between a good and great user experience. + +1. Create an endpoint in your application that can receive POST requests +2. In your Chimoney dashboard, go to the Developers tab +3. Update your application with the webhook URL +4. Specify the events you want to receive notifications for (e.g., "transfer.completed", "transfer.failed") + +Your webhook endpoint should return a 200 OK response to acknowledge receipt of the notification. + +### Sample Webhook Payload + +```json +{ + "event": "transfer.completed", + "data": { + "id": "transfer_123456", + "fromWallet": "wallet_abc123", + "amount": 100, + "sourceCurrency": "USD", + "destinationAmount": 46000, + "destinationCurrency": "NGN", + "recipient": "recipient@example.com", + "status": "completed", + "createdAt": "2023-07-23T14:25:36.789Z" + } +} +``` + +## Step 9: Making Your First Test Transfer + +Now that everything is set up, let's make a test transfer between your wallets: + +### First, Get a Transfer Quote + +```bash +curl -X POST https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/transfer/quote \ + -H "Authorization: Bearer YOUR_API_KEY" \ + -H "Content-Type: application/json" \ + -d '{ + "fromWallet": "YOUR_USD_WALLET_ID", + "amount": 10, + "destinationCurrency": "NGN" + }' +``` + +This will return a quote with the exchange rate, fees, and final amount: + +```json +{ + "status": "success", + "data": { + "sourceCurrency": "USD", + "sourceAmount": 10, + "destinationCurrency": "NGN", + "destinationAmount": 4600, + "exchangeRate": 460, + "fee": 0.25, + "totalDebit": 10.25, + "estimatedDeliveryTime": "instant" + } +} +``` + +**Developer Insight:** "Seeing the 'estimatedDeliveryTime': 'instant' in my first quote response was eye-opening. After years of building around 3-5 day transfer delays, the possibility of instant cross-border transfers changed my entire approach to the payment flow design." + +### Then, Execute the Transfer + +```bash +curl -X POST https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/transfer \ + -H "Authorization: Bearer YOUR_API_KEY" \ + -H "Content-Type: application/json" \ + -d '{ + "fromWallet": "YOUR_USD_WALLET_ID", + "toWallet": "YOUR_NGN_WALLET_ID", + "amount": 10, + "destinationCurrency": "NGN", + "description": "Test transfer" + }' +``` + +If successful, you should receive a response with the transfer details, including the converted amount and transaction ID. + +✓ **Achievement unlocked:** You've successfully executed your first cross-currency transfer! + +## Step 10: Verifying the Transfer + +Check that the transfer was successful by getting the details of your wallets: + +```bash +curl -X GET https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/get?id=YOUR_USD_WALLET_ID \ + -H "Authorization: Bearer YOUR_API_KEY" +``` + +```bash +curl -X GET https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/get?id=YOUR_NGN_WALLET_ID \ + -H "Authorization: Bearer YOUR_API_KEY" +``` + +You should see the updated balances reflecting the transfer you made. + +## Step 11: Sending Money to Email or Phone Number + +One of the powerful features of the Multi-Currency Wallet Transfer API is the ability to send money to someone using just their email or phone number, even if they don't have a Chimoney account yet. + +This is where the magic of modern fintech truly shines – removing the requirement for recipients to have specific accounts or wallets before they can receive funds. It's like being able to send a package to someone without needing their exact street address – just their name and email. + +### Sending to an Email + +```bash +curl -X POST https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/transfer \ + -H "Authorization: Bearer YOUR_API_KEY" \ + -H "Content-Type: application/json" \ + -d '{ + "fromWallet": "YOUR_USD_WALLET_ID", + "email": "recipient@example.com", + "amount": 10, + "destinationCurrency": "NGN", + "description": "Payment for services" + }' +``` + +### Sending to a Phone Number + +```bash +curl -X POST https://sandbox-api.chimoney.io/v0.2.4/multicurrency-wallets/transfer \ + -H "Authorization: Bearer YOUR_API_KEY" \ + -H "Content-Type: application/json" \ + -d '{ + "fromWallet": "YOUR_USD_WALLET_ID", + "phoneNumber": "+2348012345678", + "amount": 10, + "destinationCurrency": "NGN", + "description": "Payment for services" + }' +``` + +Recipients will receive a notification with instructions on how to claim their funds. + +**Developer Insight:** "When I first implemented the email transfer feature, our customer support tickets for payment issues dropped by nearly 40%. Users no longer needed to navigate complex wallet setups just to receive their money." + +✓ **Achievement unlocked:** You can now send money to anyone with just their email or phone number! + +## Common Setup Issues and Solutions + +We've all experienced that moment of frustration when something doesn't work as expected. Here's how to overcome common obstacles: + +| Issue | Solution | +|-------|----------| +| "Unauthorized" error | Double-check your API key and ensure it's correctly formatted in the Authorization header | +| "Wallet not found" error | Verify the wallet ID is correct and belongs to your account | +| "Insufficient funds" error | Check your wallet balance and ensure you have enough funds for the transfer including fees | +| "Invalid currency" error | Ensure you're using supported currencies (USD, CAD, NGN) | +| Webhook not receiving events | Verify your webhook URL is publicly accessible and returns a 200 OK response | + +## Integration with Programming Languages + +### Node.js Setup + +```javascript +// Install required packages +// npm install axios dotenv + +require('dotenv').config();

Remember: every financial integration expert started exactly where you are now. + +If you haven't set up your Chimoney account and API key yet, please refer to the [Setup Guide](./setup.md) first. + +## Step 1: Create Multi-Currency Wallets + +The first step is to create wallets for each currency you want to work with. For this tutorial, we'll create wallets for USD, NGN, and CAD. + +### Creating a USD Wallet + +```javascript +// Using Node.js with Axios +const axios = require('axios'); + +const API_KEY = 'YOUR_CHIMONEY_API_KEY'; +const BASE_URL = 'https://sandbox-api.chimoney.io/v0.2.4'; + +async function createUSDWallet() { + try { + const response = await axios.post( + `${BASE_URL}/multicurrency-wallets/create`, + { + name: 'USD Wallet', + currency: 'USD' + }, + { + headers: { + 'Authorization': `Bearer ${API_KEY}`, + 'Content-Type': 'application/json' + } + } + ); + + console.log('USD Wallet created:', response.data); + return response.data.data.id; // Save this wallet ID for later use + } catch (error) { + console.error('Error creating USD wallet:', error.response?.data || error.message); + throw error; + } +} +``` + +**Developer Insight:** "There's something deeply satisfying about that first successful API response. It's like the digital equivalent of laying the foundation for a house—not glamorous yet, but essential for everything that follows." + +✓ **Achievement unlocked:** You've created your first digital currency container! + +### Creating an NGN Wallet + +```javascript +async function createNGNWallet() { + try { + const response = await axios.post( + `${BASE_URL}/multicurrency-wallets/create`, + { + name: 'NGN Wallet', + currency: 'NGN' + }, + { + headers: { + 'Authorization': `Bearer ${API_KEY}`, + 'Content-Type': 'application/json' + } + } + ); + + console.log('NGN Wallet created:', response.data); + return response.data.data.id; // Save this wallet ID for later use + } catch (error) { + console.error('Error creating NGN wallet:', error.response?.data || error.message); + throw error; + } +} +``` + +### Creating a CAD Wallet + +```javascript +async function createCADWallet() { + try { + const response = await axios.post( + `${BASE_URL}/multicurrency-wallets/create`, + { + name: 'CAD Wallet', + currency: 'CAD' + }, + { + headers: { + 'Authorization': `Bearer ${API_KEY}`, + 'Content-Type': 'application/json' + } + } + ); + + console.log('CAD Wallet created:', response.data); + return response.data.data.id; // Save this wallet ID for later use + } catch (error) { + console.error('Error creating CAD wallet:', error.response?.data || error.message); + throw error; + } +} +``` + +## Step 2: List Your Wallets + +After creating the wallets, you can list them to verify they were created successfully and check their balances: + +```javascript +async function listWallets() { + try { + const response = await axios.get( + `${BASE_URL}/multicurrency-wallets/list`, + { + headers: { + 'Authorization': `Bearer ${API_KEY}` + } + } + ); + + console.log('Your wallets:', response.data); + return response.data.data; // Array of wallet objects + } catch (error) { + console.error('Error listing wallets:', error.response?.data || error.message); + throw error; + } +} +``` + +## Step 3: Get a Transfer Quote + +Before executing a transfer, it's a good practice to get a quote to show the user the exchange rate, fees, and final amount they'll receive. This step transforms the anxiety-inducing mystery of "How much will this actually cost?" into a transparent transaction where everyone knows exactly what to expect. + +Think of it like checking the weather before going out—it helps you prepare for what's ahead and prevents unpleasant surprises: + +```javascript +async function getTransferQuote(fromWalletId, amount, destinationCurrency) { + try { + const response = await axios.post( + `${BASE_URL}/multicurrency-wallets/transfer/quote`, + { + fromWallet: fromWalletId, + amount: amount, + destinationCurrency: destinationCurrency + }, + { + headers: { + 'Authorization': `Bearer ${API_KEY}`, + 'Content-Type': 'application/json' + } + } + ); + + console.log('Transfer quote:', response.data); + return response.data.data; + } catch (error) { + console.error('Error getting transfer quote:', error.response?.data || error.message); + throw error; + } +} +``` + +Example usage: + +```javascript +// Get a quote for converting 100 USD to NGN +const quote = await getTransferQuote('usd_wallet_id', 100, 'NGN'); +console.log(`100 USD = ${quote.destinationAmount} NGN`); +console.log(`Exchange rate: 1 USD = ${quote.exchangeRate} NGN`); +console.log(`Fee: ${quote.fee} USD`); +console.log(`Total debit: ${quote.totalDebit} USD`); +``` + +## Step 4: Execute a Wallet-to-Wallet Transfer + +Now that we have our wallets and a quote, we can execute a transfer between wallets: + +```javascript +async function transferBetweenWallets(fromWalletId, toWalletId, amount, destinationCurrency, description) { + try { + const response = await axios.post( + `${BASE_URL}/multicurrency-wallets/transfer`, + { + fromWallet: fromWalletId, + toWallet: toWalletId, + amount: amount, + destinationCurrency: destinationCurrency, + description: description || 'Wallet to wallet transfer' + }, + { + headers: { + 'Authorization': `Bearer ${API_KEY}`, + 'Content-Type': 'application/json' + } + } + ); + + console.log('Transfer successful:', response.data); + return response.data.data; + } catch (error) { + console.error('Error transferring funds:', error.response?.data || error.message); + throw error; + } +} +``` + +Example usage: + +```javascript +// Transfer 100 USD to NGN wallet +const transfer = await transferBetweenWallets( + 'usd_wallet_id', + 'ngn_wallet_id', + 100, + 'NGN', + 'Salary payment' +); + +console.log(`Transfer ID: ${transfer.id}`); +console.log(`Amount sent: ${transfer.amount} ${transfer.sourceCurrency}`); +console.log(`Amount received: ${transfer.destinationAmount} ${transfer.destinationCurrency}`); +console.log(`Status: ${transfer.status}`); +``` + +When this code executes successfully, there's a moment of pure developer satisfaction—watching the funds move from one currency to another in seconds rather than days. What might seem like a simple transfer to us represents something much more significant to the recipient: timely access to their earnings, ability to pay bills without delays, or simply the peace of mind that comes with financial stability. + +✓ **Achievement unlocked:** You've successfully moved money across currencies in seconds instead of days! + +## Step 5: Transfer to Email or Phone Number + +One of the powerful features of Chimoney's API is the ability to send money to someone using just their email or phone number, even if they don't have a Chimoney account yet. + +This is where the magic of modern fintech truly shines. It's like being able to deliver a package to someone without needing their exact street address—just their name and email. This seemingly small feature can be transformative for businesses working with freelancers in regions with limited banking infrastructure: + +```javascript +async function transferToEmail(fromWalletId, email, amount, destinationCurrency, description) { + try { + const response = await axios.post( + `${BASE_URL}/multicurrency-wallets/transfer`, + { + fromWallet: fromWalletId, + email: email, + amount: amount, + destinationCurrency: destinationCurrency, + description: description || 'Payment via email' + }, + { + headers: { + 'Authorization': `Bearer ${API_KEY}`, + 'Content-Type': 'application/json' + } + } + ); + + console.log('Transfer to email successful:', response.data); + return response.data.data; + } catch (error) { + console.error('Error transferring to email:', error.response?.data || error.message); + throw error; + } +} +``` + +```javascript +async function transferToPhone(fromWalletId, phoneNumber, amount, destinationCurrency, description) { + try { + const response = await axios.post( + `${BASE_URL}/multicurrency-wallets/transfer`, + { + fromWallet: fromWalletId, + phoneNumber: phoneNumber, + amount: amount, + destinationCurrency: destinationCurrency, + description: description || 'Payment via phone' + }, + { + headers: { + 'Authorization': `Bearer ${API_KEY}`, + 'Content-Type': 'application/json' + } + } + ); + + console.log('Transfer to phone successful:', response.data); + return response.data.data; + } catch (error) { + console.error('Error transferring to phone:', error.response?.data || error.message); + throw error; + } +} +``` + +Example usage: + +```javascript +// Send 50 USD (converted to NGN) to an email +const emailTransfer = await transferToEmail( + 'usd_wallet_id', + 'recipient@example.com', + 50, + 'NGN', + 'Freelance payment' +); + +// Send 75 USD (converted to NGN) to a phone number +const phoneTransfer = await transferToPhone( + 'usd_wallet_id', + '+2348012345678', + 75, + 'NGN', + 'Contract payment' +); +``` + +## Step 6: Check Transfer Status + +After initiating a transfer, you may want to check its status: + +```javascript +async function checkTransferStatus(transferId) { + try { + const response = await axios.get( + `${BASE_URL}/multicurrency-wallets/transfer/status?id=${transferId}`, + { + headers: { + 'Authorization': `Bearer ${API_KEY}` + } + } + ); + + console.log('Transfer status:', response.data); + return response.data.data; + } catch (error) { + console.error('Error checking transfer status:', error.response?.data || error.message); + throw error; + } +} +``` + +Example usage: + +```javascript +// Check the status of a transfer +const status = await checkTransferStatus('transfer_123456'); +console.log(`Transfer status: ${status.status}`); +console.log(`Created at: ${new Date(status.createdAt).toLocaleString()}`); +if (status.completedAt) { + console.log(`Completed at: ${new Date(status.completedAt).toLocaleString()}`); +} +``` + +## Step 7: Implement Error Handling + +We've all felt that moment of panic when a financial transaction fails and we don't know if the money is gone, pending, or refunded. That's why robust error handling isn't just good practice—it's essential for maintaining your users' trust and your own peace of mind. + +Proper error handling transforms a potentially anxiety-inducing experience into a manageable situation where problems have clear solutions. Here's how to handle common errors: + +```javascript +async function safeTransfer(fromWalletId, toWalletId, amount, destinationCurrency, description) { + try { + // First, check if the wallet has sufficient balance + const walletInfo = await axios.get( + `${BASE_URL}/multicurrency-wallets/get?id=${fromWalletId}`, + { + headers: { + 'Authorization': `Bearer ${API_KEY}` + } + } + ); + + const wallet = walletInfo.data.data; + if (wallet.balance < amount) { + throw new Error(`Insufficient balance: ${wallet.balance} ${wallet.currency} available, ${amount} ${wallet.currency} required`); + } + + // Get a quote to check fees + const quote = await getTransferQuote(fromWalletId, amount, destinationCurrency); + const totalRequired = quote.totalDebit; + + if (wallet.balance < totalRequired) { + throw new Error(`Insufficient balance including fees: ${wallet.balance} ${wallet.currency} available, ${totalRequired} ${wallet.currency} required (includes ${quote.fee} fee)`); + } + + // Execute the transfer + const transfer = await transferBetweenWallets( + fromWalletId, + toWalletId, + amount, + destinationCurrency, + description + ); + + return { + success: true, + transfer: transfer, + quote: quote + }; + } catch (error) { + // Handle specific API errors + if (error.response) { + const statusCode = error.response.status; + const errorData = error.response.data; + + if (statusCode === 401) { + return { + success: false, + error: 'Authentication failed. Please check your API key.', + details: errorData + }; + } else if (statusCode === 404) { + return { + success: false, + error: 'Wallet not found. Please check the wallet IDs.', + details: errorData + }; + } else if (statusCode === 400) { + return { + success: false, + error: 'Invalid request.

This is where separate pieces become a cohesive experience—like assembling individual ingredients into a delicious meal that's greater than the sum of its parts. + +Your users won't see the individual API calls; they'll experience the outcome: the delight of sending money across borders without complexity, the relief of knowing exactly what fees to expect, and the satisfaction of seeing the recipient receive funds instantly: + +```javascript +async function completeTransferFlow() { + try { + // Step 1: Create wallets if they don't exist + console.log('Creating wallets...'); + const usdWalletId = await createUSDWallet(); + const ngnWalletId = await createNGNWallet(); + + // Step 2: List wallets to check balances + console.log('Listing wallets...'); + const wallets = await listWallets(); + const usdWallet = wallets.find(w => w.id === usdWalletId); + const ngnWallet = wallets.find(w => w.id === ngnWalletId); + + console.log(`USD Wallet balance: ${usdWallet.balance} USD`); + console.log(`NGN Wallet balance: ${ngnWallet.balance} NGN`); + + // Step 3: Get a transfer quote + console.log('Getting transfer quote...'); + const amount = 100; // USD + const quote = await getTransferQuote(usdWalletId, amount, 'NGN'); + + console.log(`Exchange rate: 1 USD = ${quote.exchangeRate} NGN`); + console.log(`${amount} USD = ${quote.destinationAmount} NGN`); + console.log(`Fee: ${quote.fee} USD`); + console.log(`Total debit: ${quote.totalDebit} USD`); + + // Step 4: Confirm with user (simulated here) + const userConfirmed = true; // In a real app, this would come from user input + + if (userConfirmed) { + // Step 5: Execute the transfer + console.log('Executing transfer...'); + const transfer = await transferBetweenWallets( + usdWalletId, + ngnWalletId, + amount, + 'NGN', + 'Cross-currency transfer demo' + ); + + console.log(`Transfer successful! ID: ${transfer.id}`); + console.log(`Amount sent: ${transfer.amount} ${transfer.sourceCurrency}`); + console.log(`Amount received: ${transfer.destinationAmount} ${transfer.destinationCurrency}`); + + // Step 6: Check updated balances + console.log('Checking updated balances...'); + const updatedWallets = await listWallets(); + const updatedUsdWallet = updatedWallets.find(w => w.id === usdWalletId); + const updatedNgnWallet = updatedWallets.find(w => w.id === ngnWalletId); + + console.log(`New USD Wallet balance: ${updatedUsdWallet.balance} USD`); + console.log(`New NGN Wallet balance: ${updatedNgnWallet.balance} NGN`); + + return { + success: true, + transfer: transfer, + usdBalance: updatedUsdWallet.balance, + ngnBalance: updatedNgnWallet.balance + }; + } else { + console.log('Transfer cancelled by user'); + return { + success: false, + reason: 'cancelled' + }; + } + } catch (error) { + console.error('Error in transfer flow:', error); + return { + success: false, + error: error.message || 'Unknown error occurred', + details: error + }; + } +} +``` + +## Step 9: Implementing a Transfer UI (Web Example) + +The API is powerful, but users interact with interfaces, not endpoints. A thoughtful UI can transform a technical process into an intuitive experience that builds trust and confidence. + +Remember: behind every transfer is a real person with real needs—perhaps a freelancer waiting for payment to buy groceries, or a parent sending money to a child studying abroad. Your interface is the bridge between complex financial operations and human needs: + +Here's a simple HTML and JavaScript example for implementing a transfer UI in a web application: + +```html + + + + + + Multi-Currency Wallet Transfer + + + +

Every month, I spent nearly three full days coordinating with different banks, tracking wire transfers, and answering questions from our team members about delayed payments or unexpected fee deductions. +> +> Our Nigerian developers would typically wait 3-5 business days for their payments to clear, often losing 4-7% in combined bank fees and poor exchange rates. Our Canadian design team faced similar issues, just on a different scale. We tried several other payment platforms before, but each one only solved part of the problem or worked in certain regions. +> +> Since implementing Chimoney six months ago, we've reduced our payroll processing time from three days to just two hours per month. Our team members now receive their full compensation within minutes instead of days, and we're saving approximately $3,200 monthly in fees alone. +> +> What surprised me the most was the positive impact on team morale. During our last quarterly survey, 92% of our international team members specifically mentioned timely and reliable payments as a factor in their job satisfaction, up from just 64% before Chimoney. +> +> The most significant change for me personally? I no longer receive those frustrating 'Where's my payment?' emails that used to flood my inbox every month. Now I can focus on strategic financial planning rather than troubleshooting payment issues. For a growing company with team members across 12 countries, having this level of reliability and efficiency in our payment system has been transformative." + +## Beyond Payroll: Additional Applications + +The Multi-Currency Wallet Transfer functionality extends beyond payroll to other use cases: + +- **Marketplace payouts**: Online platforms can pay sellers across multiple countries +- **Affiliate commissions**: Companies can distribute commission payments to global partners +- **Expense reimbursements**: Businesses can quickly reimburse employee expenses in local currencies +- **Subscription refunds**: Services can process refunds to international customers in their native currency +- **Cross-border supplier payments**: Pay international vendors efficiently +- **Freelancer payments**: Pay remote contractors in their preferred currency +- **Interledger integration**: Connect with the broader Interledger Protocol ecosystem for global payments + +## Technical Integration Points + +The Multi-Currency Wallet Transfer API works seamlessly with other Chimoney endpoints: + +1. **Wallet Creation**: Use the `/multicurrency-wallets/create` endpoint to set up wallets for each currency +2. **Wallet Management**: Monitor and update wallets using the `/multicurrency-wallets/update` endpoint +3. **Transfer Quotes**: Get real-time exchange rates with the `/multicurrency-wallets/transfer/quote` endpoint +4. **Wallet Listing**: View all wallets with the `/multicurrency-wallets/list` endpoint +5. **Wallet Details**: Check balances with the `/multicurrency-wallets/get` endpoint + +## Conclusion + +Chimoney's Multi-Currency Wallet Transfer API represents a significant advancement for businesses operating globally.
