# Mayar Payment Integration

Integrate Mayar.id payment platform via MCP (Model Context Protocol) for Indonesian payment processing.

## Prerequisites

1. **Mayar.id account** - Sign up at https://mayar.id
2. **API Key** - Generate from https://web.mayar.id/api-keys
3. **mcporter configured** - MCP must be set up in Clawdbot

## Setup

### 1. Store API Credentials

```bash
mkdir -p ~/.config/mayar
cat > ~/.config/mayar/credentials << EOF
MAYAR_API_TOKEN="your-jwt-token-here"
EOF
chmod 600 ~/.config/mayar/credentials
```

### 2. Configure MCP Server

Add to `config/mcporter.json`:

```json
{
  "mcpServers": {
    "mayar": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.mayar.id/sse",
        "--header",
        "Authorization:YOUR_API_TOKEN_HERE"
      ]
    }
  }
}
```

Replace `YOUR_API_TOKEN_HERE` with actual token.

### 3. Test Connection

```bash
mcporter list mayar
```

Should show 15+ available tools.

## Core Workflows

### Create Invoice with Payment Link

**Most common use case:** Generate payment link for customer.

```bash
mcporter call mayar.create_invoice \
  name="Customer Name" \
  email="[email protected]" \
  mobile="\"628xxx\"" \
  description="Order description" \
  redirectURL="https://yoursite.com/thanks" \
  expiredAt="2026-12-31T23:59:59+07:00" \
  items='[{"quantity":1,"rate":500000,"description":"Product A"}]'
```

**Returns:**
```json
{
  "id": "uuid",
  "transactionId": "uuid", 
  "link": "https://subdomain.myr.id/invoices/slug",
  "expiredAt": 1234567890
}
```

**Key fields:**
- `mobile` - MUST be string with quotes: `"\"628xxx\""`
- `expiredAt` - ISO 8601 format with timezone
- `items` - Array of `{quantity, rate, description}`
- `redirectURL` - Where customer goes after payment

### WhatsApp Integration Pattern

```javascript
// 1. Create invoice
const invoice = /* mcporter call mayar.create_invoice */;

// 2. Format message
const message = `
✅ *Order Confirmed!*

*Items:*
• Product Name
  Rp ${amount.toLocaleString('id-ID')}

*TOTAL: Rp ${total.toLocaleString('id-ID')}*

💳 *Pembayaran:*
${invoice.data.link}

⏰ Berlaku sampai: ${expiryDate}

Terima kasih! 🙏
`.trim();

// 3. Send via WhatsApp
message({
  action: 'send',
  channel: 'whatsapp',
  target: customerPhone,
  message: message
});
```

### Check Payment Status

```bash
# Get latest transactions (check if paid)
mcporter call mayar.get_latest_transactions page:1 pageSize:10

# Get unpaid invoices
mcporter call mayar.get_latest_unpaid_transactions page:1 pageSize:10
```

Filter by status: `"created"` (unpaid) → `"paid"` (success).

### Other Operations

```bash
# Check account balance
mcporter call mayar.get_balance

# Get customer details
mcporter call mayar.get_customer_detail \
  customerName="Name" \
  customerEmail="[email protected]" \
  page:1 pageSize:10

# Filter by time period
mcporter call mayar.get_transactions_by_time_period \
  page:1 pageSize:10 \
  period:"this_month" \
  sortField:"createdAt" \
  sortOrder:"DESC"
```

## Common Patterns

### Multi-Item Invoice

```javascript
items='[
  {"quantity":2,"rate":500000,"description":"Product A"},
  {"quantity":1,"rate":1000000,"description":"Product B"}
]'
// Total: 2M (2×500K + 1×1M)
```

### Subscription/Recurring

Use membership tools:

```bash
mcporter call mayar.get_membership_customer_by_specific_product \
  productName:"Premium Membership" \
  productLink:"your-product-link" \
  productId:"product-uuid" \
  page:1 pageSize:10 \
  memberStatus:"active"
```

### Payment Confirmation Flow

**Option A: Webhook** (Real-time)
- Register webhook URL with Mayar
- Receive instant payment notifications
- Best for production

**Option B: Polling** (Simpler)
- Poll `get_latest_transactions` every 30-60s
- Check for new payments
- Best for MVP/testing

## Troubleshooting

**404 on payment link:**
- Link format: `https://your-subdomain.myr.id/invoices/slug`
- Check dashboard for correct subdomain
- Default may be account name

**Invalid mobile number:**
- Mobile MUST be string: `"\"628xxx\""` (with escaped quotes)
- Format: `628xxxxxxxxxx` (no + or spaces)

**Expired invoice:**
- Default expiry is `expiredAt` timestamp
- Customer can't pay after expiration
- Create new invoice if needed

- Cache responses when possible

## Error Codes

```json
{
  "statusCode": 400,
  "messages": "Invalid request",
  "errors": [
    {
      "field": "email",
      "message": "Invalid email format"

**Response:**
```json
{
  "currentPage": 1,
  "totalPage": 5,

  "data": [...]
}
```

## Filtering & Sorting

**Time-based filtering:**
- `period` - `today`, `this_week`, `this_month`, `this_year`
- `startAt` / `endAt` - Custom date range (ISO 8601)

**Sorting:**
- `sortField` - Field to sort by (`createdAt`, `amount`)
- `sortOrder` - `ASC` or `DESC`

## Best Practices

### 1. Use Idempotency
Store invoice IDs to avoid duplicate invoice creation:

```javascript
const existingInvoice = cache.get(orderId);
if (existingInvoice) {
  return existingInvoice;
}

const newInvoice = await createInvoice(...);
cache.set(orderId, newInvoice);
```

### 2. Handle Webhooks Properly
```javascript
app.post('/webhook', (req, res) => {
  // Respond immediately
  res.status(200).json({ received: true });
  
  // Process async
  processPayment(req.body).catch(console.error);
});
```

### 3. Validate Webhook Signature
(If Mayar provides signature verification - check docs)

### 4. Set Appropriate Expiry
```javascript
// Short for immediate purchase (24h)
const expiry = new Date(Date.now() + 24 * 60 * 60 * 1000);

// Longer for invoices (7-30 days)
const expiry = new Date(Date.now() + 7 * 24 * 60 * 60 * 1000);
```

### 5. Store Transaction Data
```javascript
{
  orderId: "ORD-123",
  invoiceId: "mayar-invoice-uuid",
  transactionId: "mayar-transaction-uuid",
  customerId: "customer-uuid",
  amount: 500000,
  status: "pending",
  createdAt: "2026-01-31T12:00:00Z",
  paidAt: null
}
```

## Sandbox vs Production

**Sandbox:**
- Use for testing
- No real payments
- Separate dashboard (web.mayar.club)
- Separate API keys

**Production:**
- Real payments
- Live dashboard (web.mayar.id)
- Production API keys
- Use after thorough testing

**Migration:**
- Generate new API key from production
- Update base URL
- Test with small amount first

# Mayar Integration Examples

Real-world integration patterns for common use cases.

## WhatsApp E-Commerce Bot

### Complete Order Flow

```javascript
// 1. Customer sends order via WhatsApp
// "Mau order wedding template + maintenance 2 bulan"

// 2. Parse order and create invoice
const items = [
  { quantity: 1, rate: 750000, description: "Wedding Website Template" },
  { quantity: 2, rate: 1000000, description: "Monthly Maintenance" }
];

const total = items.reduce((sum, item) => sum + (item.quantity * item.rate), 0);
// Total: 2,750,000

// 3. Create invoice via mcporter
const invoice = execSync(`
  mcporter call mayar.create_invoice \\
    name="Customer Name" \\
    email="[email protected]" \\
    mobile="\\"6281234567890\\"" \\
    description="Wedding Template + Maintenance Package" \\

    expiredAt="2026-02-07T23:59:59+07:00" \\
    items='${JSON.stringify(items)}' \\
    --output json
`);

const result = JSON.parse(invoice);
const paymentLink = result.data.link.replace('tsrlabs', 'yoursubdomain');

// 4. Format WhatsApp message
const message = `
✅ *Order Confirmed!*

*Package:* Wedding Template + Maintenance

*Items:*
• Wedding Website Template
  Rp 750.000

    period:"today" \
    sortField:"createdAt" \
    sortOrder:"DESC" \

`);

const transactions = JSON.parse(today).data;
const revenue = transactions.reduce((sum, t) => sum + t.amount, 0);
const count = transactions.length;

const report = `
📊 *Daily Revenue Report*
Date: ${new Date().toLocaleDateString('id-ID')}

💰 Total Revenue: Rp ${revenue.toLocaleString('id-ID')}
📦 Transactions: ${count}
💵 Average: Rp ${Math.round(revenue / count).toLocaleString('id-ID')}

Top 5 Sales:

// Send to admin
message({
  action: 'send',

## Error Handling

### Retry Failed Invoices

```javascript
function createInvoiceWithRetry(data, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      const invoice = execSync(`
        mcporter call mayar.create_invoice \
          name="${data.name}" \
          email="${data.email}" \
          mobile="\\"${data.mobile}\\"" \
          description="${data.description}" \
          redirectURL="${data.redirectURL}" \
          expiredAt="${data.expiredAt}" \
          items='${JSON.stringify(data.items)}' \
          --output json
      `);
      
      return JSON.parse(invoice);
    } catch (error) {
      console.error(`Attempt ${i + 1} failed:`, error.message);
      if (i === maxRetries - 1) throw error;
      
      // Wait before retry (exponential backoff)
      await new Promise(resolve => setTimeout(resolve, 1000 * Math.pow(2, i)));
    }
  }
}
```

### Handle Expired Invoices

```javascript
function recreateExpiredInvoice(oldInvoiceId) {
  // Get old invoice details
  const unpaid = execSync(`
    mcporter call mayar.get_latest_unpaid_transactions page:1 pageSize:100 --output json
  `);
  
  const oldInvoice = JSON.parse(unpaid).data.find(t => t.id === oldInvoiceId);
  
  if (!oldInvoice) {
    throw new Error('Invoice not found');
  }
  
  // Create new invoice with same details but new expiry
  const newExpiry = new Date(Date.now() + 7 * 24 * 60 * 60 * 1000).toISOString();
  
  return createInvoice({
    name: oldInvoice.paymentLinkName,
    email: oldInvoice.customer.email,
    mobile: oldInvoice.customer.mobile,
    description: oldInvoice.paymentLinkDescription,
    expiredAt: newExpiry,
    items: oldInvoice.items // Extract from original
  });
}
```

## Best Practices

### 1. Always Store Invoice IDs
```javascript
// Store mapping: customer → invoice ID
const invoiceDB = {
  [customerPhone]: {
    invoiceId: result.data.id,
    transactionId: result.data.transactionId,
    createdAt: Date.now(),
    status: 'pending'
  }
};
```

### 2. Set Reasonable Expiry Times
```javascript
// For immediate purchases: 24 hours
const expiry24h = new Date(Date.now() + 24 * 60 * 60 * 1000);

// For orders: 7 days
const expiry7d = new Date(Date.now() + 7 * 24 * 60 * 60 * 1000);

// For invoices: 30 days
const expiry30d = new Date(Date.now() + 30 * 24 * 60 * 60 * 1000);
```

### 3. Format Phone Numbers Correctly
```javascript
function formatPhoneForMayar(phone) {
  // Remove all non-digits
  let cleaned = phone.replace(/\D/g, '');
  
  // Add country code if missing
  if (!cleaned.startsWith('62')) {
    cleaned = '62' + cleaned.replace(/^0+/, '');
  }
  
  return cleaned;
}
```

### 4. Handle Timezone Correctly
```javascript
// Always use Jakarta timezone for Indonesian customers
const expiry = new Date();
expiry.setDate(expiry.getDate() + 7);
const expiryISO = expiry.toISOString().replace('Z', '+07:00');
```

```
