Dodo Payments License Keys

Reference:docs.dodopayments.com/features/license-keys

License keys authorize access to your digital products. Use them for software licensing, per-seat controls, and gating premium features.

Overview

License keys are unique tokens that:

• Authorize access to software, plugins, CLIs
• Limit activations per user or device
• Gate downloads, updates, or premium features
• Can be linked to subscriptions or one-time purchases

Creating License Keys

In Dashboard

1. Go to Dashboard → License Keys

2. Click "Create License Key"

3. Configure settings:

   • Expiry Date : Duration or "no expiry" for perpetual
   • Activation Limit : Max concurrent activations (1, 5, unlimited)
   • Activation Instructions : Steps for customers

4. Save the license key configuration

Auto-Generation on Purchase

License keys can be automatically generated when a product is purchased:

1. Configure your product with license key settings
2. When purchased, a key is generated and emailed to customer
3. license_key.created webhook is fired

API Reference

Public Endpoints (No API Key Required)

These endpoints can be called directly from client applications:

Authenticated Endpoints (API Key Required)

Implementation Examples

Activate a License Key

import DodoPayments from 'dodopayments';

// No API key needed for public endpoints
const client = new DodoPayments();

async function activateLicense(licenseKey: string, deviceName: string) {
  try {
    const response = await client.licenses.activate({
      license_key: licenseKey,
      name: deviceName, // e.g., "John's MacBook Pro"
    });

    return {
      success: true,
      instanceId: response.id,
      message: 'License activated successfully',
    };
  } catch (error: any) {
    return {
      success: false,
      message: error.message || 'Activation failed',
    };
  }
}

Validate a License Key

import DodoPayments from 'dodopayments';

const client = new DodoPayments();

async function validateLicense(licenseKey: string) {
  try {
    const response = await client.licenses.validate({
      license_key: licenseKey,
    });

    return {
      valid: response.valid,
      activations: response.activations_count,
      maxActivations: response.activations_limit,
      expiresAt: response.expires_at,
    };
  } catch (error) {
    return { valid: false };
  }
}

Deactivate a License

import DodoPayments from 'dodopayments';

const client = new DodoPayments();

async function deactivateLicense(licenseKey: string, instanceId: string) {
  try {
    await client.licenses.deactivate({
      license_key: licenseKey,
      license_key_instance_id: instanceId,
    });

    return { success: true, message: 'License deactivated' };
  } catch (error: any) {
    return { success: false, message: error.message };
  }
}

Desktop App Integration

Electron App Example

// main/license.ts
import Store from 'electron-store';
import DodoPayments from 'dodopayments';

const store = new Store();
const client = new DodoPayments();

interface LicenseInfo {
  key: string;
  instanceId: string;
  activatedAt: string;
}

export async function activateLicense(licenseKey: string): Promise<boolean> {
  try {
    // Get device identifier
    const deviceName = `${os.hostname()} - ${os.platform()}`;
    
    const response = await client.licenses.activate({
      license_key: licenseKey,
      name: deviceName,
    });

    // Store license info locally
    const licenseInfo: LicenseInfo = {
      key: licenseKey,
      instanceId: response.id,
      activatedAt: new Date().toISOString(),
    };
    
    store.set('license', licenseInfo);
    return true;
  } catch (error) {
    console.error('Activation failed:', error);
    return false;
  }
}

export async function checkLicense(): Promise<boolean> {
  const license = store.get('license') as LicenseInfo | undefined;
  
  if (!license) {
    return false;
  }

  try {
    const response = await client.licenses.validate({
      license_key: license.key,
    });

    return response.valid;
  } catch (error) {
    // If offline, trust local license (with optional grace period)
    const activatedAt = new Date(license.activatedAt);
    const daysSinceActivation = (Date.now() - activatedAt.getTime()) / (1000 * 60 * 60 * 24);
    
    // Allow 30-day offline grace period
    return daysSinceActivation < 30;
  }
}

export async function deactivateLicense(): Promise<boolean> {
  const license = store.get('license') as LicenseInfo | undefined;
  
  if (!license) {
    return true;
  }

  try {
    await client.licenses.deactivate({
      license_key: license.key,
      license_key_instance_id: license.instanceId,
    });

    store.delete('license');
    return true;
  } catch (error) {
    console.error('Deactivation failed:', error);
    return false;
  }
}

React Component for License Input

// components/LicenseActivation.tsx
import { useState } from 'react';

interface Props {
  onActivated: () => void;
}

export function LicenseActivation({ onActivated }: Props) {
  const [licenseKey, setLicenseKey] = useState('');
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const handleActivate = async () => {
    setLoading(true);
    setError(null);

    try {
      // Call main process (Electron IPC)
      const success = await window.electronAPI.activateLicense(licenseKey);
      
      if (success) {
        onActivated();
      } else {
        setError('Invalid license key. Please check and try again.');
      }
    } catch (err) {
      setError('Activation failed. Please try again.');
    } finally {
      setLoading(false);
    }
  };

  return (
    <div className="license-form">
      <h2>Activate Your License</h2>
      <p>Enter your license key to unlock all features.</p>
      
      <input
        type="text"
        value={licenseKey}
        onChange={(e) => setLicenseKey(e.target.value)}
        placeholder="XXXX-XXXX-XXXX-XXXX"
        disabled={loading}
      />
      
      {error && <p className="error">{error}</p>}
      
      <button onClick={handleActivate} disabled={loading || !licenseKey}>
        {loading ? 'Activating...' : 'Activate License'}
      </button>
      
      <a href="https://yoursite.com/purchase" target="_blank">
        Don't have a license? Purchase here
      </a>
    </div>
  );
}

CLI Tool Integration

Node.js CLI Example

// src/license.ts
import Conf from 'conf';
import DodoPayments from 'dodopayments';
import { machineIdSync } from 'node-machine-id';

const config = new Conf({ projectName: 'your-cli' });
const client = new DodoPayments();

export async function activate(licenseKey: string): Promise<void> {
  const machineId = machineIdSync();
  const deviceName = `CLI - ${process.platform} - ${machineId.substring(0, 8)}`;

  try {
    const response = await client.licenses.activate({
      license_key: licenseKey,
      name: deviceName,
    });

    config.set('license', {
      key: licenseKey,
      instanceId: response.id,
      machineId,
    });

    console.log('License activated successfully!');
  } catch (error: any) {
    if (error.status === 400) {
      console.error('Invalid license key.');
    } else if (error.status === 403) {
      console.error('Activation limit reached. Deactivate another device first.');
    } else {
      console.error('Activation failed:', error.message);
    }
    process.exit(1);
  }
}

export async function checkLicense(): Promise<boolean> {
  const license = config.get('license') as any;

  if (!license) {
    return false;
  }

  try {
    const response = await client.licenses.validate({
      license_key: license.key,
    });

    return response.valid;
  } catch {
    return false;
  }
}

export async function deactivate(): Promise<void> {
  const license = config.get('license') as any;

  if (!license) {
    console.log('No active license found.');
    return;
  }

  try {
    await client.licenses.deactivate({
      license_key: license.key,
      license_key_instance_id: license.instanceId,
    });

    config.delete('license');
    console.log('License deactivated.');
  } catch (error: any) {
    console.error('Deactivation failed:', error.message);
  }
}

// Middleware to check license before commands
export function requireLicense() {
  return async () => {
    const valid = await checkLicense();
    if (!valid) {
      console.error('This command requires a valid license.');
      console.error('Run: your-cli activate <license-key>');
      process.exit(1);
    }
  };
}

CLI Commands

// src/cli.ts
import { Command } from 'commander';
import { activate, deactivate, checkLicense, requireLicense } from './license';

const program = new Command();

program
  .command('activate <license-key>')
  .description('Activate your license')
  .action(activate);

program
  .command('deactivate')
  .description('Deactivate license on this device')
  .action(deactivate);

program
  .command('status')
  .description('Check license status')
  .action(async () => {
    const valid = await checkLicense();
    console.log(valid ? 'License: Active' : 'License: Not activated');
  });

// Protected command example
program
  .command('generate')
  .description('Generate something (requires license)')
  .hook('preAction', requireLicense())
  .action(async () => {
    // Premium feature
  });

program.parse();

Webhook Integration

Handle License Key Creation

// app/api/webhooks/dodo/route.ts
export async function POST(req: NextRequest) {
  const event = await req.json();

  if (event.type === 'license_key.created') {
    const { id, key, product_id, customer_id, expires_at } = event.data;

    // Store in your database
    await prisma.license.create({
      data: {
        externalId: id,
        key: key,
        productId: product_id,
        customerId: customer_id,
        expiresAt: expires_at ? new Date(expires_at) : null,
        status: 'active',
      },
    });

    // Optional: Send custom email with activation instructions
    await sendLicenseEmail(customer_id, key, product_id);
  }

  return NextResponse.json({ received: true });
}

Server-Side Validation

For sensitive operations, validate server-side with your API key:

// app/api/validate-license/route.ts
import { NextRequest, NextResponse } from 'next/server';
import DodoPayments from 'dodopayments';

const client = new DodoPayments({
  bearerToken: process.env.DODO_PAYMENTS_API_KEY!,
});

export async function POST(req: NextRequest) {
  const { licenseKey } = await req.json();

  try {
    // Get detailed license info (requires API key)
    const licenses = await client.licenseKeys.list({
      license_key: licenseKey,
    });

    if (licenses.items.length === 0) {
      return NextResponse.json({ valid: false, error: 'License not found' });
    }

    const license = licenses.items[0];

    // Check various conditions
    const valid = 
      license.status === 'active' &&
      (!license.expires_at || new Date(license.expires_at) > new Date());

    return NextResponse.json({
      valid,
      status: license.status,
      activationsUsed: license.activations_count,
      activationsLimit: license.activations_limit,
      expiresAt: license.expires_at,
    });
  } catch (error: any) {
    return NextResponse.json({ valid: false, error: error.message }, { status: 500 });
  }
}

Best Practices

1. Keep Limits Clear

Choose sensible defaults for expiry and activations based on your product type.

2. Guide Users

Provide precise activation instructions:

• "Paste the key in Settings → License"
• "Run: mycli activate <key>"
• Include self-serve documentation links

3. Validate Server-Side

For critical access control, always validate on your server before granting access.

4. Handle Offline Gracefully

Allow a grace period for offline use in desktop/CLI apps.

5. Monitor Events

Use webhooks to detect abuse patterns and automate revocations.

6. Provide Easy Deactivation

Let users deactivate devices themselves to manage their activation slots.

Common Patterns

Feature Gating

async function canAccessFeature(feature: string, licenseKey: string) {
  const { valid } = await validateLicense(licenseKey);
  
  if (!valid) return false;

  // Map features to license tiers
  const featureTiers = {
    'basic-export': ['starter', 'pro', 'enterprise'],
    'advanced-export': ['pro', 'enterprise'],
    'api-access': ['enterprise'],
  };

  const license = await getLicenseDetails(licenseKey);
  return featureTiers[feature]?.includes(license.tier);
}

Subscription-Linked Licenses

When license is linked to a subscription:

// Handle subscription.cancelled webhook
if (event.type === 'subscription.cancelled') {
  const { customer_id } = event.data;
  
  // Disable associated license keys
  const licenses = await client.licenseKeys.list({ customer_id });
  
  for (const license of licenses.items) {
    await client.licenseKeys.update(license.id, {
      status: 'disabled',
    });
  }
}
