### Using Node.js/Axios (Recommended)
#### Simple Usage
```javascript
const { ERPNextSecureClient } = require('./secure_api_client');
async function example() {
const client = new ERPNextSecureClient('http://localhost:8080');
// Authenticate with API token (uses environment variables)
await client.authenticateWithToken();
// Get customers
const customers = await client.get('/api/resource/Customer');
console.log(customers.data);
// Create new customer
const newCustomer = await client.post('/api/resource/Customer', {
customer_name: 'API Test Customer',
customer_type: 'Individual'
});
await client.logout();
}
example().catch(console.error);
```
#### Advanced Usage with Caching and Retry
```javascript
const { ERPNextAdvancedSecureClient } = require('./secure_api_client');
async function advancedExample() {
const client = new ERPNextAdvancedSecureClient('http://localhost:8080', {
enableCache: true, // Response caching
retryAttempts: 3, // Auto-retry failures
rateLimitPerMinute: 60 // Rate limiting
});
await client.authenticateWithToken();
// First call hits API
const customers = await client.get('/api/resource/Customer');
// Second call uses cache (faster)
const cachedCustomers = await client.get('/api/resource/Customer');
await client.logout();
}
```
#### Environment Variables Setup
```bash
# Create .env file
echo 'ERPNEXT_API_KEY="your_key_here"' > .env
echo 'ERPNEXT_API_SECRET="your_secret_here"' >> .env
# Test environment variables
node test_env_vars.js
```

# ERPNext API Security Guide
## Authentication Methods
ERPNext supports multiple authentication methods, each with different use cases and security implications:
## 1. Session-Based Authentication (Cookies)
### How it works:
```bash
# Login and get session cookie
curl -c cookies.txt -X POST \
-H "Content-Type: application/json" \
-d '{"usr":"Administrator","pwd":"LocalDev123!"}' \
http://localhost:8080/api/method/login
# Use cookie for subsequent requests
curl -b cookies.txt http://localhost:8080/api/resource/Customer
```
### Pros:
- ✅ Simple to implement
- ✅ Works well for browser-based applications
- ✅ Session management handled by server
- ✅ Can implement session timeout
### Cons:
- ❌ Vulnerable to CSRF attacks without proper tokens
- ❌ Not ideal for mobile/API clients
- ❌ Requires cookie storage
- ❌ Session state on server
### Security Best Practices:
- Use HTTPS only
- Set HttpOnly flag
- Set Secure flag
- Implement CSRF tokens
- Set appropriate session timeouts
## 2. API Key & Secret (Token Authentication)
### How it works:
```bash
# Use API key and secret in Authorization header
curl -H "Authorization: token api_key:api_secret" \
http://localhost:8080/api/resource/Customer
```
### Setup:
1. Login to ERPNext UI
2. Go to User Settings → API Access
3. Generate API Key and Secret
4. Store securely
### Example Implementation:
```python
import requests
headers = {
'Authorization': 'token abc123:xyz789'
}
response = requests.get('http://localhost:8080/api/resource/Customer', headers=headers)
```
### Pros:
- ✅ Stateless authentication
- ✅ Better for API/mobile clients
- ✅ No CSRF vulnerability
- ✅ Can be revoked easily
- ✅ Per-user access control
### Cons:
- ❌ Keys must be stored securely
- ❌ No automatic expiration (unless implemented)
- ❌ Transmitted with every request
### Security Best Practices:
- **Never** commit API keys to version control
- Use environment variables
- Rotate keys regularly
- Use HTTPS only
- Implement IP whitelisting
## 3. OAuth 2.0 (Most Secure for Third-Party Apps)
### How it works:
ERPNext supports OAuth 2.0 for third-party integrations.
### Setup:
1. Register OAuth client in ERPNext
2. Implement OAuth flow
3. Use access tokens for API calls
### Example Flow:
```python
# 1. Redirect user to authorize
authorize_url = "http://localhost:8080/api/method/frappe.integrations.oauth2.authorize"
# 2. Exchange code for token
token_url = "http://localhost:8080/api/method/frappe.integrations.oauth2.get_token"
# 3. Use access token
headers = {'Authorization': 'Bearer access_token_here'}
```
### Pros:
- ✅ Industry standard
- ✅ Granular permissions
- ✅ Token expiration
- ✅ Refresh tokens
- ✅ No password sharing
### Cons:
- ❌ More complex to implement
- ❌ Requires OAuth server setup
## 4. Basic Authentication (Not Recommended)
### How it works:
```bash
curl -u Administrator:LocalDev123! \
http://localhost:8080/api/resource/Customer
```
### Pros:
- ✅ Simple
### Cons:
- ❌ Credentials sent with every request
- ❌ Base64 encoding (not encryption)
- ❌ No session management
- ❌ Security risk
## Security Comparison Matrix
| Method | Security Level | Use Case | Implementation Complexity |
|--------|---------------|----------|--------------------------|
| OAuth 2.0 | ⭐⭐⭐⭐⭐ | Third-party apps, Mobile apps | High |
| API Key/Secret | ⭐⭐⭐⭐ | Server-to-server, CLI tools | Low |
| Session/Cookies | ⭐⭐⭐ | Web applications | Low |
| Basic Auth | ⭐⭐ | Testing only | Very Low |
## Recommended Security Architecture
### For Web Applications:
```javascript
// Use session cookies with CSRF tokens
fetch('/api/resource/Customer', {
credentials: 'include',
headers: {
'X-CSRF-Token': getCsrfToken()
}
})
```
### For Mobile Applications:
```swift
// Use API tokens with secure storage
let headers = [
"Authorization": "token \(secureStorage.getApiKey()):\(secureStorage.getApiSecret())"
]
```
### For Server-to-Server:
```python
# Use API tokens with environment variables
import os
import requests
headers = {
'Authorization': f'token {os.environ["ERPNEXT_API_KEY"]}:{os.environ["ERPNEXT_API_SECRET"]}'
}
```
### For Third-Party Integrations:
```javascript
// Implement OAuth 2.0 flow
const accessToken = await getOAuthToken();
const response = await fetch('/api/resource/Customer', {
headers: {
'Authorization': `Bearer ${accessToken}`
}
});
```
## Additional Security Measures
### 1. Rate Limiting
```nginx
# nginx configuration
limit_req_zone $binary_remote_addr zone=api:10m rate=60r/m;
location /api {
limit_req zone=api burst=10 nodelay;
}
```
### 2. IP Whitelisting
```python
# In ERPNext site_config.json
{
"api_ip_whitelist": ["192.168.1.0/24", "10.0.0.0/8"]
}
```
### 3. HTTPS Configuration
```nginx
server {
listen 443 ssl http2;
ssl_certificate /path/to/cert.pem;
ssl_certificate_key /path/to/key.pem;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers HIGH:!aNULL:!MD5;
}
```
### 4. API Monitoring
```python
# Log all API access
import frappe
@frappe.whitelist()
def log_api_access():
frappe.log_error(
title="API Access",
message=f"User: {frappe.session.user}, IP: {frappe.request.remote_addr}"
)
```
### 5. Field-Level Permissions
```python
# Restrict sensitive fields
{
"doctype": "Customer",
"field_permissions": {
"credit_limit": ["Sales Manager"],
"tax_id": ["Accounts Manager"]
}
}
```

### Advanced Security Features (Node.js)
```javascript
/**
* Advanced Security Features for ERPNext API Client
*/
// 1. Rate Limiting Implementation
class RateLimitedClient extends SecureERPNextClient {
constructor(baseUrl, options = {}) {
super(baseUrl);
this.requestsPerMinute = options.requestsPerMinute || 60;
this.requestQueue = [];
this.setupRateLimit();
}
setupRateLimit() {
this.client.interceptors.request.use(async (config) => {
await this.checkRateLimit();
return config;
});
}
async checkRateLimit() {
const now = Date.now();
const oneMinuteAgo = now - 60000;
// Remove old requests
this.requestQueue = this.requestQueue.filter(time => time > oneMinuteAgo);
// Check if we're at the limit
if (this.requestQueue.length >= this.requestsPerMinute) {
const waitTime = this.requestQueue[0] + 60000 - now;
console.log(`⏳ Rate limit reached. Waiting ${waitTime}ms...`);
await new Promise(resolve => setTimeout(resolve, waitTime));
}
this.requestQueue.push(now);
}
}
// 2. Request Retry with Exponential Backoff
class RetryClient extends RateLimitedClient {
constructor(baseUrl, options = {}) {
super(baseUrl, options);
this.maxRetries = options.maxRetries || 3;
this.retryDelay = options.retryDelay || 1000;
this.setupRetry();
}
setupRetry() {
this.client.interceptors.response.use(
response => response,
async (error) => {
const config = error.config;
if (!config || config.retry >= this.maxRetries) {
return Promise.reject(error);
}
// Only retry on network errors or 5xx responses
const shouldRetry = !error.response ||
(error.response.status >= 500 && error.response.status < 600);
if (!shouldRetry) {
return Promise.reject(error);
}
config.retry = (config.retry || 0) + 1;
const delay = this.retryDelay * Math.pow(2, config.retry - 1);
console.log(`🔄 Retrying request (${config.retry}/${this.maxRetries}) in ${delay}ms`);
await new Promise(resolve => setTimeout(resolve, delay));
return this.client(config);
}
);
}
}
// 3. Request Caching
class CachedClient extends RetryClient {
constructor(baseUrl, options = {}) {
super(baseUrl, options);
this.cache = new Map();
this.cacheTimeout = options.cacheTimeout || 300000; // 5 minutes
}
async get(endpoint, params = {}) {
const cacheKey = `GET:${endpoint}:${JSON.stringify(params)}`;
const cached = this.cache.get(cacheKey);
if (cached && Date.now() - cached.timestamp < this.cacheTimeout) {
console.log('📦 Cache hit:', endpoint);
return cached.data;
}
const result = await super.get(endpoint, params);
this.cache.set(cacheKey, {
data: result,
timestamp: Date.now()
});
return result;
}
clearCache() {
this.cache.clear();
console.log('🗑️ Cache cleared');
}
}
```
## Docker Security Configuration
### Environment Variables (.env)
```bash
# Never commit .env files
ERPNEXT_API_KEY=your_api_key_here
ERPNEXT_API_SECRET=your_api_secret_here
ERPNEXT_URL=https://localhost:8080
# Use Docker secrets in production
docker secret create erpnext_api_key api_key.txt
docker secret create erpnext_api_secret api_secret.txt
```
### Docker Compose with Secrets
```yaml
version: '3.8'
services:
app:
image: frappe/erpnext:v14
secrets:
- erpnext_api_key
- erpnext_api_secret
environment:
API_KEY_FILE: /run/secrets/erpnext_api_key
API_SECRET_FILE: /run/secrets/erpnext_api_secret
secrets:
erpnext_api_key:
external: true
erpnext_api_secret:
external: true
```
## Conclusion
### Best Practices Summary:
1. **For Production APIs**: Use API Key/Secret or OAuth 2.0
2. **For Web Apps**: Use session cookies with CSRF protection
3. **For Mobile Apps**: Use OAuth 2.0 with secure token storage
4. **For Testing**: Use session cookies (never Basic Auth in production)
### Security Priority:
1. Always use HTTPS
2. Implement rate limiting
3. Use strong authentication
4. Monitor and log access
5. Regular security audits
### Remember:
- **Cookies alone are NOT the most secure** - they need CSRF protection
- **API tokens are better for APIs** - stateless and no CSRF risk
- **OAuth 2.0 is best for third-party** - industry standard
- **Never use Basic Auth in production** - credentials exposed
The choice depends on your use case, but for pure API access, **token-based authentication (API Key/Secret or OAuth)** is generally more secure than cookies.

## API Development ## API Development
### Accessing APIs ### Complete API Ecosystem
ERPNext provides REST APIs accessible at `http://localhost:8080/api/` ERPNext provides comprehensive REST APIs with **771 documented DocTypes** across all modules.
### Common API Endpoints ### API Documentation Files
- **Login**: `POST /api/method/login` - **[API_ENDPOINTS.md](API_ENDPOINTS.md)** - Complete documentation of all 771 DocTypes
- **Resources**: `/api/resource/{DocType}` - **[API_GUIDE.md](API_GUIDE.md)** - Comprehensive usage guide with examples
- **Methods**: `/api/method/{method_path}` - **[API_SECURITY.md](API_SECURITY.md)** - Security best practices and authentication methods
- **[NODEJS_API_CLIENT.md](NODEJS_API_CLIENT.md)** - Node.js/Axios client documentation
### Testing APIs ### Secure API Clients
Two production-ready API clients are available:
#### Python Client (`secure_api_client.py`)
```bash ```bash
# Login and get session # Test Python client
curl -c cookies.txt -X POST \ python3 secure_api_client.py
-H "Content-Type: application/json" \
-d '{"usr":"Administrator","pwd":"LocalDev123!"}' \
http://localhost:8080/api/method/login
# Use session for API calls # Generate API documentation
curl -b cookies.txt http://localhost:8080/api/resource/Item python3 generate_api_docs.py
``` ```
### API Documentation #### Node.js/Axios Client (`secure_api_client.js`)
See [API_GUIDE.md](API_GUIDE.md) for comprehensive API documentation. ```bash
# Install dependencies
npm install axios dotenv
# Test Node.js client
node secure_api_client.js
# Run examples
node examples/api_examples.js
```
### Authentication Methods (Security Ranked)
1. **OAuth 2.0** (Best for third-party apps)
2. **API Tokens** (Recommended for APIs) - `Authorization: token key:secret`
3. **Session Cookies** (Web apps only, with CSRF protection)
4. **Basic Auth** (Testing only, never production)
### Quick API Testing
```bash
# Environment setup
export ERPNEXT_API_KEY="your_key_here"
export ERPNEXT_API_SECRET="your_secret_here"
# Test with built-in scripts
./test_api.sh # Basic cURL tests
node test_env_vars.js # Node.js environment test
python3 secure_api_client.py # Python secure client
```
### Common API Patterns
- **List all**: `GET /api/resource/{DocType}`
- **Get one**: `GET /api/resource/{DocType}/{name}`
- **Create**: `POST /api/resource/{DocType}`
- **Update**: `PUT /api/resource/{DocType}/{name}`
- **Delete**: `DELETE /api/resource/{DocType}/{name}`
### API Discovery Tools
```bash
# Generate/update complete API documentation
python3 generate_api_docs.py
# Discover endpoints
./discover_api_endpoints.sh
```

const customers = await client.get('/api/resource/Customer', {
filters: JSON.stringify([['disabled', '=', 0]]),
fields: JSON.stringify(['name', 'customer_name', 'customer_type']),
limit_page_length: 10
});
// Create new customer
const newCustomer = await client.post('/api/resource/Customer', {
customer_name: 'API Test Customer',
customer_type: 'Company',
customer_group: 'All Customer Groups',
territory: 'All Territories'
});
// Update customer
await client.put(`/api/resource/Customer/${newCustomer.data.name}`, {
customer_type: 'Individual'
});
```
### Item Management
```javascript
// Get items with stock info
const items = await client.get('/api/resource/Item', {
fields: JSON.stringify(['item_code', 'item_name', 'standard_rate']),
filters: JSON.stringify([['is_stock_item', '=', 1]]),
order_by: 'item_name asc'
});
// Create new item
const newItem = await client.post('/api/resource/Item', {
item_code: 'API-ITEM-001',
item_name: 'API Test Item',
item_group: 'All Item Groups',
stock_uom: 'Nos',
standard_rate: 100.00
});
```
### Sales Orders
```javascript
// Get recent sales orders
const salesOrders = await client.get('/api/resource/Sales Order', {
fields: JSON.stringify(['name', 'customer', 'status', 'grand_total']),
filters: JSON.stringify([['docstatus', '=', 1]]),
order_by: 'creation desc',
limit_page_length: 5
});
// Create sales order
const salesOrder = await client.post('/api/resource/Sales Order', {
customer: 'CUST-00001',
delivery_date: '2024-12-31',
items: [{
item_code: 'ITEM-001',
qty: 10,
rate: 100.00
}]
});
```
## 🎯 Error Handling
### Comprehensive Error Handling
```javascript
try {
const result = await client.get('/api/resource/Customer');
console.log(result.data);
} catch (error) {
if (error.response) {
// Server responded with error status
const status = error.response.status;
const message = error.response.data.message;
switch (status) {
case 401:
console.error('Authentication failed');
break;
case 403:
console.error('Access forbidden');
break;
case 404:
console.error('Resource not found');
break;
case 429:
console.error('Rate limit exceeded');
break;
default:
console.error(`API error: ${status} - ${message}`);
}
} else if (error.request) {
// Network error
console.error('Network error:', error.message);
} else {
// Other error
console.error('Error:', error.message);
}
}
```
### Built-in Error Handling
The client automatically handles:
- **401 Unauthorized**: Token expired/invalid
- **403 Forbidden**: Insufficient permissions
- **429 Rate Limited**: Automatic retry after delay
- **5xx Server Errors**: Automatic retry with backoff
- **Network Timeouts**: Configurable timeout handling

```
### Performance Monitoring
```javascript
// Track request performance
console.time('API Request');
const result = await client.get('/api/resource/Customer');
console.timeEnd('API Request');
// Cache hit/miss tracking
const cachedResult = await client.get('/api/resource/Customer'); // Cache hit logged
```
## 🚨 Security Best Practices
### Production Checklist
- [ ] ✅ Use HTTPS URLs only
- [ ] ✅ Store API keys in environment variables
- [ ] ✅ Enable request logging for audit trails
- [ ] ✅ Implement rate limiting
- [ ] ✅ Use token authentication (not sessions)
- [ ] ✅ Set appropriate timeouts
- [ ] ✅ Handle errors gracefully
- [ ] ✅ Monitor API usage patterns
- [ ] ✅ Rotate API keys regularly
- [ ] ✅ Validate all inputs
### Development Tips
```javascript
// ✅ Good: Use environment variables
const client = new ERPNextSecureClient(process.env.ERPNEXT_URL);
await client.authenticateWithToken(); // Uses env vars
// ❌ Bad: Hardcode credentials
const client = new ERPNextSecureClient('http://localhost:8080');
await client.authenticateWithToken('hardcoded-key', 'hardcoded-secret');
// ✅ Good: Handle errors
try {
const result = await client.get('/api/resource/Customer');
return result.data;
} catch (error) {
logger.error('Customer fetch failed:', error.message);
throw new APIError('Failed to fetch customers');
}
// ❌ Bad: Ignore errors
const result = await client.get('/api/resource/Customer');
return result.data; // Will crash if API fails
```
## 📖 Integration Examples
### Express.js API
```javascript
const express = require('express');
const { ERPNextSecureClient } = require('./secure_api_client');
const app = express();
const erpClient = new ERPNextSecureClient();
app.get('/customers', async (req, res) => {
try {
await erpClient.authenticateWithToken();
const customers = await erpClient.get('/api/resource/Customer', {
limit_page_length: 10
});
res.json(customers.data);
} catch (error) {
res.status(500).json({ error: 'Failed to fetch customers' });
} finally {
await erpClient.logout();
}
});
```
### React/Next.js Frontend
```javascript
// api/erpnext.js
import { ERPNextSecureClient } from '../lib/secure_api_client';
export async function getCustomers() {
const client = new ERPNextSecureClient(process.env.NEXT_PUBLIC_ERPNEXT_URL);
await client.authenticateWithToken(
process.env.ERPNEXT_API_KEY,
process.env.ERPNEXT_API_SECRET
);
const customers = await client.get('/api/resource/Customer');
await client.logout();
return customers.data;
}
```

const items = await client.get('/api/resource/Item');
console.table(items.data);
break;
default:
console.log('Available commands: customers, items');
}
await client.logout();
}
cli().catch(console.error);
```
## 🔧 Troubleshooting
### Common Issues
**Authentication Failed**
```bash
# Check API key generation
# 1. Login to ERPNext → Settings → My Settings

### Common Operations ### 📚 Documentation Files:
- **[API_ENDPOINTS.md](API_ENDPOINTS.md)** - Complete list of all API endpoints (771 DocTypes)
- **[API_GUIDE.md](API_GUIDE.md)** - Detailed usage guide with examples
- **[API_SECURITY.md](API_SECURITY.md)** - Security best practices and authentication methods
- **[NODEJS_API_CLIENT.md](NODEJS_API_CLIENT.md)** - Complete Node.js/Axios client guide
### 🔐 Security Recommendations:
- **Production**: Use API tokens (not cookies) - `Authorization: token key:secret`
- **Web Apps**: Use session cookies with CSRF protection
- **Mobile Apps**: Use OAuth 2.0
- **Always**: Use HTTPS, never HTTP
### 🚀 API Client Quick Start:
#### **Python Client:**
```bash
# Test secure API access (Python)
python3 secure_api_client.py
# Generate complete API documentation
python3 generate_api_docs.py
# Basic API testing
./test_api.sh
```
#### **Node.js/Axios Client:**
```bash
# Install dependencies
npm install axios dotenv
# Setup environment
cp .env.example .env # Edit with your API keys
# Test secure API access (Node.js)
node secure_api_client.js
# Run practical examples
node examples/api_examples.js
# Test environment variables
node test_env_vars.js
```
### 🔑 **API Authentication Setup:**
1. **Generate API Keys:**
- Login to ERPNext → Settings → My Settings
- Scroll to "API Access" section → Generate Keys
- Copy API Key and Secret
2. **Set Environment Variables:**
```bash
# Method 1: .env file (recommended)
echo 'ERPNEXT_API_KEY="your_key_here"' > .env
echo 'ERPNEXT_API_SECRET="your_secret_here"' >> .env
# Method 2: Export in terminal
export ERPNEXT_API_KEY="your_key_here"
export ERPNEXT_API_SECRET="your_secret_here"
```
3. **Use in your code:**
```javascript
// Node.js with Axios
const { ERPNextSecureClient } = require('./secure_api_client');
const client = new ERPNextSecureClient();
await client.authenticateWithToken(); // Uses env vars automatically
const customers = await client.get('/api/resource/Customer');
```
```python
# Python with requests
from secure_api_client import ERPNextSecureClient
client = ERPNextSecureClient()
client.authenticate_with_token() # Uses env vars automatically
customers = client.get('/api/resource/Customer')
```

This deployment uses a microservices architecture with the following containers:
### 🐳 **Docker Services:**
- **backend**: Main ERPNext/Frappe worker service
- **frontend**: Nginx service for serving static assets
- **db**: MariaDB 10.6 database
- **redis**: Redis cache and queue management
- **websocket**: Socket.io for real-time features
- **queue-default/long/short**: Background job workers
- **scheduler**: Scheduled tasks
- **configurator**: Initial configuration (runs once)
- **create-site**: Site creation (runs once)
All services communicate through the `erpnext-local` Docker network.
### 📡 **API Architecture:**

## Troubleshooting ### API Operations
### Container fails to start #### Quick API Tests
Check if the network exists:
```bash ```bash
# Test authentication
curl -c cookies.txt -X POST \
-H "Content-Type: application/json" \
-d '{"usr":"Administrator","pwd":"LocalDev123!"}' \
http://localhost:8080/api/method/login
# Get customers
curl -b cookies.txt http://localhost:8080/api/resource/Customer
# Get items with filters
curl -b cookies.txt \
"http://localhost:8080/api/resource/Item?filters=[[\"disabled\",\"=\",0]]&limit_page_length=5"
```
## 🛠️ Troubleshooting
### Container Issues
**Container fails to start:**
```bash
# Check if network exists
docker network ls | grep erpnext-local docker network ls | grep erpnext-local
```
If not found, create it: # Create network if missing
```bash
docker network create erpnext-local docker network create erpnext-local
# Check container status
docker-compose ps
``` ```
### Cannot access the application **Cannot access the application:**
- Verify all containers are running: `docker-compose ps` - Verify all containers are running: `docker-compose ps`
- Check logs for errors: `docker-compose logs` - Check logs for errors: `docker-compose logs`
- Ensure port 8080 is not blocked by firewall - Ensure port 8080 is not blocked by firewall
## FAQ ### API Issues
**Authentication failed:**
```bash
# Generate new API keys in ERPNext UI
# Settings → My Settings → API Access → Generate Keys
# Test API keys
node test_env_vars.js
python3 secure_api_client.py
```
**404 errors on API calls:**
- Remember: No browsable API at `/api/`
- Use specific endpoints: `/api/resource/DocType`
- Check [API_ENDPOINTS.md](API_ENDPOINTS.md) for available DocTypes
