WooCommerce License Manager MT4 + MT5

🧩 MAIN OBJECTIVE

I want to set up an automated licensing system for MT4 and MT5 EAs using WooCommerce and the plugin License Manager for WooCommerce. The system should:

• Generate license keys automatically after purchase

• Bind the license to the customer’s specific computer (Windows or Mac)

• Verify the license each time the EA is loaded

• Include a “Clear Activations” button in the user’s account to allow resetting the device binding

✅ DETAILED REQUIREMENTS

1. WEBSITE INTEGRATION (WOOCOMMERCE)

• Use the License Manager for WooCommerce plugin to issue and manage license keys.

• After purchase, the system automatically generates and sends a license key to the customer.

• Each license key must be bound to only one device (using a combination of hardware info such as HDD serial, computer name, MAC address, etc.).

• MT4 and MT5 licenses must be separated:

  • Each EA version (MT4 and MT5) is sold as a separate WooCommerce product.

  • MT4 EAs should only accept MT4 keys, and MT5 EAs should only accept MT5 keys.

• Add a “Clear Activations” button next to each license key in the user’s “My Account” page, allowing the customer to unbind the license from the current device and activate it on a new one.

2. EA-SIDE REQUIREMENTS (MQL4 & MQL5)

• When first loaded, the EA will ask the user to enter their license key.

• The EA should:

  • Save the license key locally (so the user doesn’t need to re-enter it).

  • Collect device info and send it with the license key to the server for verification.

  • If the key is valid and the device matches → EA runs as normal.

  • If the key is invalid or the device doesn't match → show an error message (easy to customize) and automatically remove the EA from the chart.

• The system must support both Windows and Mac users (including Mac users running Windows via virtual machines).

• Optionally, the EA may continue running for a short period if the user loses internet connection (e.g., 24h offline grace period).

3. SECURITY & SAFEGUARDS

• The system must ensure that license keys are only valid for the correct product (MT4/MT5).

• Device binding should use a secure fingerprint created using hashed values (e.g., SHA256) of multiple hardware identifiers.

• API requests should be protected with a shared secret (API key) to prevent abuse.

• The system should prevent brute-force or license sharing (limit requests per IP, etc.).

• Advice needed on how to protect the system in case the website is hacked, such as:

  • Using a firewall plugin (e.g., Wordfence)

  • Disabling XML-RPC

  • Isolating the license API on a subdomain (e.g., api.mysite.com )

  • Backing up regularly

🔧 DELIVERABLES

You (the developer) should provide:

A. WEBSITE SIDE (WordPress/WooCommerce)

• Custom plugin code or add-on to:

  • Store device information upon first activation

  • Verify the license key and device with each EA request

  • Add the “Clear Activations” button to the user’s account page

• Clear instructions on how to install and use the plugin on my live site

B. EA SIDE (MT4 & MT5)

• Sample code to be integrated into both MT4 and MT5 EAs

• Features:

  • Request license verification from the server

  • Store and load the key from local cache

  • Show customizable error messages

• Easy-to-follow instructions for integration

✅ SUMMARY

The whole system must be:

• Simple and seamless for end users

• Highly secure and resistant to abuse

• Easy to update and maintain
