Implement License Validation in 5 Minutes

Two simple steps to protect your software

Vanilla REST API

Step 1

Get user's license key

// License key provided by your end user
                        const userLicenseKey = getUserLicenseKey(); 
                        const productName = 'Your Product Name';
                        const instanceId = generateInstanceId();
Step 2

Validate the license

fetch('https://api.licenflow.com/api/v1/validate-license', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    license_key: userLicenseKey,
    product: productName,
    instance_id: instanceId,
    feature_used: 'Core Application'  // Optional: Track which feature is being used
  })
})
.then(res => res.json())
.then(data => {
  if (data.valid) {
    // License is valid - start your application
    startApplication();
  } else {
    // Show error to user
    showLicenseError(data.message);
  }
});

Node.js

Step 1

Get user's license key

const axios = require('axios');

// Get license key from your end user
const userLicenseKey = getUserLicenseKey();
const productName = 'Your Product Name';
const instanceId = generateInstanceId();
Step 2

Validate the license

const response = await axios.post(
  'https://api.licenflow.com/api/v1/validate-license',
  {
    license_key: userLicenseKey,
    product: productName,
    instance_id: instanceId,
    feature_used: 'Core Application'  // Optional: Track which feature is being used
  }
);

if (response.data.valid) {
  // License is valid - start your application
  startApplication();
} else {
  // Show error to user
  showLicenseError(response.data.message);
}

PHP

Step 1

Prepare the request data

// Get license key from your end user
$userLicenseKey = getUserLicenseKey();
$productName = 'Your Product Name';
$instanceId = generateInstanceId();

$data = [
    'license_key' => $userLicenseKey,
    'product' => $productName,
    'instance_id' => $instanceId,
    'feature_used' => 'Core Application'  // Optional: Track which feature is being used
];
Step 2

Validate the license

$ch = curl_init('https://api.licenflow.com/api/v1/validate-license');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);

$response = curl_exec($ch);
$result = json_decode($response, true);

if ($result['valid']) {
    // License is valid - start your application
    startApplication();
} else {
    // Show error to user
    showLicenseError($result['message']);
}

Python

Step 1

Prepare the request data

import requests

# Get license key from your end user
user_license_key = get_user_license_key()
product_name = 'Your Product Name'
instance_id = generate_instance_id()

data = {
    'license_key': user_license_key,
    'product': product_name,
    'instance_id': instance_id,
    'feature_used': 'Core Application'  # Optional: Track which feature is being used
}
Step 2

Validate the license

response = requests.post(
    'https://api.licenflow.com/api/v1/validate-license',
    json=data
)

result = response.json()

if result['valid']:
    # License is valid - start your application
    start_application()
else:
    # Show error to user
    show_license_error(result['message'])

Go

Step 1

Prepare the request

import (
    "bytes"
    "encoding/json"
    "net/http"
)

// Get license key from your end user
userLicenseKey := getUserLicenseKey()

data := map[string]string{
    "license_key": userLicenseKey,
    "product":     "Your Product Name",
    "instance_id": generateInstanceId(),
    "feature_used": "Core Application",  // Optional: Track which feature is being used
}
Step 2

Validate the license

jsonData, _ := json.Marshal(data)
resp, err := http.Post(
    "https://api.licenflow.com/api/v1/validate-license",
    "application/json",
    bytes.NewBuffer(jsonData),
)
defer resp.Body.Close()

var result map[string]interface{}
json.NewDecoder(resp.Body).Decode(&result)

if result["valid"].(bool) {
    // License is valid - start your application
    startApplication()
} else {
    // Show error to user
    showLicenseError(result["message"].(string))
}

Java

Step 1

Prepare the request

import java.net.http.*;
import java.net.URI;
import org.json.JSONObject;

// Get license key from your end user
String userLicenseKey = getUserLicenseKey();

JSONObject data = new JSONObject();
data.put("license_key", userLicenseKey);
data.put("product", "Your Product Name");
data.put("instance_id", generateInstanceId());
data.put("feature_used", "Core Application");  // Optional: Track which feature is being used
Step 2

Validate the license

HttpClient client = HttpClient.newHttpClient();
HttpRequest request = HttpRequest.newBuilder()
    .uri(URI.create("https://api.licenflow.com/api/v1/validate-license"))
    .header("Content-Type", "application/json")
    .POST(HttpRequest.BodyPublishers.ofString(data.toString()))
    .build();

HttpResponse<String> response = client.send(request, 
    HttpResponse.BodyHandlers.ofString());

JSONObject result = new JSONObject(response.body());

if (result.getBoolean("valid")) {
    // License is valid - start your application
    startApplication();
} else {
    // Show error to user
    showLicenseError(result.getString("message"));
}

Complete Flow - Pseudo-code

Understanding the complete license validation flow:

// ═══════════════════════════════════════════════════════
// COMPLETE LICENSE VALIDATION FLOW
// ═══════════════════════════════════════════════════════

// 1. End user purchases a license
//    ↳ Receives: "ABCD-1234-EFGH-5678"

// 2. End user installs your software
//    ↳ Software prompts: "Enter your license key"

// 3. User enters: "ABCD-1234-EFGH-5678"
//    ↳ getUserLicenseKey() returns this value

// 4. Your software validates the license:

POST https://api.licenflow.com/api/v1/validate-license

Request Body:
{
  "license_key": "ABCD-1234-EFGH-5678",  ← from end user
  "product": "SuperCRM",              ← hardcoded in your software
  "instance_id": "PC-JohnDoe-12345"   ← auto-generated from system
}

// 5. LicenFlow API responds:

Response (Success):
{
  "valid": true,
  "expires_at": "2025-12-31T23:59:59Z",
  "activations": {
    "current": 1,
    "maximum": 5
  }
}

// 6. Your software checks the response:

if (response.valid === true) {
    // ✅ License is valid
    // → Start application normally
    // → User can use all features
    startApplication();
} else {
    // ❌ License is invalid
    // → Show error message to user
    // → Don't start application
    showLicenseError(response.message);
}

// ═══════════════════════════════════════════════════════
// IMPORTANT SECURITY NOTES
// ═══════════════════════════════════════════════════════

// ✅ INCLUDED in your distributed software:
//    • Validation endpoint URL (it's public)
//    • Your product name (it's public)
//    • Logic to prompt user for license key

// ❌ NEVER include in your distributed software:
//    • Your LicenFlow API keys
//    • Authentication tokens
//    • Customer management credentials

// ═══════════════════════════════════════════════════════
// ACTIVATION LIMITS EXAMPLE
// ═══════════════════════════════════════════════════════

// Same license key used on different devices:
// Device 1 (PC-JohnDoe-12345):
// → First activation → activations: 1/5 ✅

// Device 2 (LAPTOP-JohnDoe-67890):
// → Second activation → activations: 2/5 ✅

// Device 6 (TABLET-JohnDoe-99999):
// → Exceeds limit → activations: 6/5 ❌
// → Response: { "valid": false, "message": "Activation limit exceeded" }

Command Line / cURL

Step 1

Validate license with one command

# Simple one-line license validation
curl -X POST "https://api.licenflow.com/api/v1/validate-license" \
  -H "Content-Type: application/json" \
  -d '{"license_key":"ABCD-1234-EFGH-5678","product":"YourProduct","instance_id":"device-001","feature_used":"Core Application"}'
Step 2

Check the response

# Success response:
{
  "valid": true,
  "expires_at": "2025-12-31T23:59:59Z",
  "activations": {
    "current": 1,
    "maximum": 5
  },
  "status_code": 200
}

# Error response:
{
  "valid": false,
  "message": "License key has expired",
  "status_code": 400
}

Pay As You Go

Pay as you go is a flexible pricing model that allows customers to pay only for the resources they use. It is particularly popular in cloud computing, where customers pay for the services they actually use, rather than paying for a large bucket of unused licenses for example.

icenFlow LicenFlow - Software License Management

🚀 Efficient Alternative Functionality

To further optimize the process and improve user experience, we implement additional methods:

  • Local Validation with JWT Tokens: Upon license activation, a digitally signed JWT token is generated and stored on the user's device. This allows license validation locally, reducing the need for constant server calls. Our systems support several thousand calls per minute, but on the other hand, reducing communications from the lean application design perspective in certain scenarios helps with lightweight usage on the user side.
  • License Cache with Validity Period: The JWT token includes a short expiration time, allowing the application to function efficiently even with limited connectivity, renewing the license only when necessary.
  • Real-Time Notifications via Webhooks: With webhooks, any changes in license status (renewals, revocations, or updates) are immediately notified to the application, ensuring the user always has the most up-to-date status.
