Satim Payment Gateway Integration

Satim Payment Gateway Integration

A Model Context Protocol (MCP) server for integrating with the SATIM payment gateway system in Algeria. The server provides a structured interface for processing CIB/Edhahabia card payments through the SATIM-ePAY platform. This package enables AI assistants like Cursor, Claude, and Copilot to directly access your Razorpay account data through a standardized interface.

Configuration

MCP Client Configuration

To use this server with an MCP client (like Claude Desktop), add to your configuration:

{
  "mcpServers": {
    "satim-payment": {
      "command": "node",
      "args": [
        "--experimental-strip-types",
        "/path/to/your/satim-mcp-server.ts"
      ],
      "env": {
        "SATIM_USERNAME": "your_test_username",
        "SATIM_PASSWORD": "your_test_password",
        "NODE_ENV": "development"
      }
    }
  }
}

Initial Setup

Before using any payment tools, configure your SATIM credentials:

// Configure credentials
await mcp.callTool("configure_credentials", {
  userName: "your_merchant_username",
  password: "your_merchant_password"
});

Environment Variables

For production, consider using environment variables:

SATIM_USERNAME=your_merchant_username
SATIM_PASSWORD=your_merchant_password
SATIM_TERMINAL_ID=your_terminal_id
SATIM_BASE_URL=https://test.satim.dz/payment/rest  # or https://satim.dz/payment/rest for production

Payment Flow

The complete payment process follows these steps:

1. Order Registration

const registrationResult = await mcp.callTool("register_order", {
  orderNumber: "ORDER_001_2024",
  amountInDA: 1500.50,  // Amount in Algerian Dinars
  returnUrl: "https://yoursite.com/payment/success",
  failUrl: "https://yoursite.com/payment/failure",
  force_terminal_id: "E005005097",
  udf1: "merchant_ref_123",
  language: "FR"
});

// Response includes orderId and formUrl
// Redirect customer to formUrl for payment

2. Customer Payment

• Customer fills CIB/Edhahabia card details on SATIM form
• Customer is redirected back to your returnUrl/failUrl

3. Order Confirmation

const confirmResult = await mcp.callTool("confirm_order", {
  orderId: "received_order_id",
  language: "FR"
});

// Validate the response
const validation = await mcp.callTool("validate_payment_response", {
  response: confirmResult
});

4. Display Results

Based on validation results, display appropriate messages to customers.

Testing

Method 1: Quick Test

Create a simple test file test-simple.js:

import { spawn } from 'child_process';

// Start the MCP server
const server = spawn('npx', ['tsx', 'satim-mcp-server.ts'], {
  stdio: ['pipe', 'pipe', 'inherit']
});

console.log('SATIM MCP Server started for testing');

// Let it run for a few seconds then exit
setTimeout(() => {
  server.kill();
  console.log('Test completed');
}, 5000);

Run with:

node test-simple.js

Method 2: Full Integration Test

Create test-client.ts following the example in the documentation, then run:

npm run test

Method 3: HTTP Wrapper for API Testing

Use the HTTP wrapper example provided in the documentation to create REST API endpoints for easier testing with tools like Postman or curl.

Troubleshooting

Common Issues and Solutions

1. "Cannot use import statement outside a module"

   # Make sure package.json has "type": "module"
   npm pkg set type=module
   

2. "Module not found" errors

   # Reinstall dependencies
   rm -rf node_modules package-lock.json
   npm install
   

3. TypeScript compilation errors

   # Check tsconfig.json configuration
   # Make sure all dependencies are installed
   npm install --save-dev @types/node
   

4. Server connection issues

   # Check if server is running
   ps aux | grep tsx
   
   # Check for port conflicts
   lsof -i :3000  # if using HTTP wrapper
   

Debug Mode

Enable debug logging:

DEBUG=true npx tsx satim-mcp-server.ts

Integration Requirements

SSL Security

• Mandatory: Your website must have SSL certificate
• All API calls must use HTTPS

User Interface Requirements

Payment Page

• Display final amount prominently (bold, larger font)
• Include CAPTCHA to prevent automated submissions
• Show CIB logo on payment button
• Display terms and conditions with customer acknowledgment
• Redirect to SATIM page in independent browser window

Success Page Display

For accepted payments, show:

• Transaction message (respCode_desc)
• Transaction ID (orderId)
• Order number (orderNumber)
• Authorization code (approvalCode)
• Transaction date/time
• Payment amount with currency
• Payment method (CIB/Edhahabia)
• SATIM contact: 3020 3020

Success Page Actions

• Print receipt option
• Download PDF receipt
• Email PDF receipt to third party

Rejection Page

• Display rejection message in three languages
• Show SATIM contact information

Amount Handling

Amounts must be multiplied by 100 when sent to SATIM:

• 50.00 DA → send 5000
• 806.50 DA → send 80650

The MCP server handles this conversion automatically.

Error Handling

Order Registration Errors

• Invalid credentials
• Duplicate order number
• Invalid amount (< 50 DA)
• Missing required parameters

Confirmation Errors

Refund Errors

Examples

Complete Payment Flow

// 1. Configure credentials
await mcp.callTool("configure_credentials", {
  userName: "test_merchant",
  password: "test_password"
});

// 2. Register order
const order = await mcp.callTool("register_order", {
  orderNumber: `ORDER_${Date.now()}`,
  amountInDA: 250.75,
  returnUrl: "https://mystore.dz/payment/success",
  failUrl: "https://mystore.dz/payment/failure",
  force_terminal_id: "E005005097",
  udf1: "customer_ref_456",
  language: "FR",
  description: "Achat produit électronique"
});

// 3. Redirect customer to order.formUrl
// Customer completes payment and returns

// 4. Confirm payment
const confirmation = await mcp.callTool("confirm_order", {
  orderId: order.orderId,
  language: "FR"
});

// 5. Validate response
const validation = await mcp.callTool("validate_payment_response", {
  response: confirmation
});

// 6. Handle result
if (validation.status === "ACCEPTED") {
  // Process successful payment
  console.log("Payment successful:", validation.displayMessage);
} else if (validation.status === "REJECTED") {
  // Handle rejection
  console.log("Payment rejected");
} else {
  // Handle error
  console.log("Payment error:", validation.displayMessage);
}

Processing Refunds

// Full refund
const refund = await mcp.callTool("refund_order", {
  orderId: "123456789AZERTYUIOPL",
  amountInDA: 250.75,  // Full original amount
  language: "FR"
});

// Partial refund
const partialRefund = await mcp.callTool("refund_order", {
  orderId: "123456789AZERTYUIOPL",
  amountInDA: 100.00,  // Partial amount
  language: "FR"
});

Security Considerations

Credentials Management

• Store credentials securely (environment variables, key vault)
• Use HTTPS for all communications
• Implement proper authentication for your API endpoints

Order Number Security

• Use unique, non-sequential order numbers
• Include timestamp or random elements
• Validate order ownership before confirmation

Data Validation

• Always validate amounts on server side
• Verify order status before processing confirmations
• Implement idempotency for refund operations

Logging and Monitoring

• Log all payment transactions
• Monitor for suspicious activities
• Implement rate limiting for API calls

Production Deployment

Environment Configuration

# Production endpoints
SATIM_BASE_URL=https://satim.dz/payment/rest

# Development/Testing endpoints  
SATIM_BASE_URL=https://test.satim.dz/payment/rest

Health Checks

Implement health check endpoints to monitor gateway connectivity:

// Add to your server
app.get('/health/satim', async (req, res) => {
  try {
    // Test connection to SATIM
    const response = await axios.get(`${SATIM_BASE_URL}/health`);
    res.json({ status: 'healthy', satim: 'connected' });
  } catch (error) {
    res.status(503).json({ status: 'unhealthy', error: error.message });
  }
});
