BOG Payment Gateway Integration

This skill provides guidance for integrating with the Bank of Georgia (BOG) Online Payment API.

Quick Reference

IMPORTANT:

• All callback URLs MUST use HTTPS
• All API requests MUST include Accept-Language: ka or Accept-Language: en header

Integration Flow

1. Authenticate - Get access token using client credentials
2. Create Order - Submit order with basket items and callbacks
3. Redirect - Send customer to payment page (URL from response)
4. Handle Callback - Receive payment result at callback URL
5. Verify - Check payment status via API

Authentication

const getAccessToken = async (clientId: string, clientSecret: string) => {
  const credentials = Buffer.from(`${clientId}:${clientSecret}`).toString('base64');

  const response = await fetch(
    'https://oauth2.bog.ge/auth/realms/bog/protocol/openid-connect/token',
    {
      method: 'POST',
      headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'Authorization': `Basic ${credentials}`
      },
      body: 'grant_type=client_credentials'
    }
  );

  const { access_token, expires_in } = await response.json();
  return { access_token, expires_in };
};

Core Endpoints

Create Order

POST https://api.bog.ge/payments/v1/ecommerce/orders
Authorization: Bearer {access_token}
Content-Type: application/json

Request body:

{
  "callback_url": "https://example.com/callback",
  "external_order_id": "ORDER-123",
  "purchase_units": {
    "currency": "GEL",
    "total_amount": 100.00,
    "basket": [
      {
        "product_id": "PROD-1",
        "quantity": 1,
        "unit_price": 100.00
      }
    ]
  },
  "redirect_urls": {
    "success": "https://example.com/success",
    "fail": "https://example.com/fail"
  }
}

Response includes _links.redirect.href for payment page URL.

Get Payment Details

GET https://api.bog.ge/payments/v1/receipt/{order_id}
Authorization: Bearer {access_token}

Implementation Checklist

1. Store client_id and client_secret securely (env vars)
2. Implement token caching with expiry handling
3. Use HTTPS for all callback URLs
4. Implement idempotency keys for order creation
5. Handle all response codes appropriately
6. Log transaction IDs for debugging
