This is the recommended way of installing any WordPress plugin available on the official repository.

• Open the WordPress Dashboard of your website
• Navigate to Plugins → Add new
• Search for License Manager  using the search bar located on the top-right side of the screen
• In the displayed search results, click on Install Now on the License Manager
• Click on Activate if you wish to activate the plugin immediately

To manually install the plugin, follow these steps:

• Open the plugin website on WordPress.org
• Download the plugin by clicking the Download button located on the top-right side of the screen
• Open your WordPress Dashboard
• Navigate to Plugins → Add new
• At the top of the screen, click  Upload plugin
• Click on Browse… and select the plugin file you previously downloaded, then click on Install Now
• Click on Activate plugin if you wish to activate it immediately

The plugin stores all license keys in an encrypted fashion inside the database. During activation, the plugin will create the following directory.

wp-content/uploads/lmfwc-files

Inside this directory, the plugin creates two files (defuse.txt and secret.txt). The contents of these files are used to encrypt, decrypt, and hash all license keys.

Before doing anything else, please create a backup of these two files and store them somewhere safe. If anything happens, and these files are deleted or overwritten, you will permanently lose all license keys stored in your database!

The plugin will also create a .htaccess file in the above-mentioned directory. This file disables direct browser access to the folder, preventing unwanted visitors from seeing your cryptographic secrets.

However, if your server runs NGINX instead of Apache, the file is completely ignored. In this case, you can either manually create a NGINX directive or follow the guide in the optimization subsection (recommended).

We recommend that you move the cryptographic secrets into the configuration file of your WordPress website, also known as „wp-config.php“. This will reduce the amount of requests to the server file system and move the cryptographic secrets to a safer place.

To do this, open the wp-config.php file and add the following lines to it:

[php] define('LMFWC_PLUGIN_SECRET', 'secret.txt');
define('LMFWC_PLUGIN_DEFUSE', 'defuse.txt'); [/php]

Replace secret.txt and defuse.txt with their file contents, respectively. Afterward, create a backup of these two files somewhere safe (if you haven’t already) and delete the lmfwc-files directory completely.

If your license keys are not visible anymore, then something went wrong. You can always restore the files and remove the two added lines to revert the changes.

The general settings section has been divided into three sub-sections: License keys, My account, and REST API.

Go to WooCommerce > Settings > License Manager > General

License Keys

The “license keys” settings section

The “Obscure licenses” setting allows users to configure whether license keys will be hidden in the administrator interface (backend). This will prevent anyone from directly looking at the plain-text, decrypted license keys.

Backend Configuration:

Obscure licenses impact:

The “Allow duplicates” setting allows the user to add duplicate license keys to the database. When adding a license key, the plugin will no longer check if said license key is already present inside the database.

The Product downloads allow you to enter the changelog and product version from settings (Pro)

The Download expires  allows you to download the digital/virtual products when the license has expired (Pro)

The License Expiration Format allows you to format the date and time of license expiry shown on the order and my account pages.

REST API

The “REST API” settings section

The “API & SSL” setting determines whether the REST API will be accessible over insecure HTTP connections instead of the secure HTTPS channel. This should only be used in development or testing/staging environments, never in a productive environment. Leaving this setting on a productive website exposes your API calls to man-in-the-middle attacks.

The “Enable/disable API routes” allows users to enable and disable API routes individually. Always turn off the REST API routes that your application does not use.

The WooCommerce settings section has been divided into three sub-sections: License key delivery, Branding, and My account.

Go to Dashboard > WooCommerce > Settings > License Manager > WooCommerce

License Key Delivery

The “license key delivery” settings section

The “Automatic delivery” setting determines whether license keys will be automatically delivered after the triggered order delivery. This is great if you want to run manual checks on the orders before sending out your licenses, however in most scenarios you will probably want to have this setting turned on.

The “Define license key delivery” setting allows the user to individually enable the order status on which the license key would be delivered.

The “Stock management” setting enables automatic stock management for WooCommerce products 

Backend Configuration:

Stock Synchronize in Products:

Go to Dashboard > Products > Inventory Tab and enable the track stock quantity option.

Go to License Manager Tab, enable sell license keys for this product, and sell license keys from available stock options to enable automatic stock sync.

Branding

The “Company Logo” setting allows the user to upload an image that will be displayed on a License Certificate when it is downloaded by the end-user.

Company Logo impact:

Navigate to My Account > License keys and click on view

Click the Download button next to the certificate to download the product license certificate.

Now your Company Logo will appear inside the pdf certificate downloaded

If a WooCommerce order contains licensed products, then the corresponding license keys will be used/generated once the order status is set to “Completed”. These license keys will then be visibly marked as sold/delivered in the license key overview, and inside their corresponding orders. An example of this is shown below; an order which contains two licensed products.

License keys sold by a WooCommerce order are displayed inside the order itself

If you had to edit or replace the license keys for an existing order you can easily email the customer their new license keys. When editing an order, check out the “Send license key(s) to customer” order action on the right-hand side of the screen, as shown below.

Validating Custom Request Data

This tutorial will demonstrate how you can perform additional request data validation, and abort a REST API call if your validation did not pass. In this specific tutorial we will pass an additional UUID to the license activation request, then check if the license has previously been activated using that UUID, if that’s the case we will return an error.

To sum everything up, we will demonstrate the following:

1. Adding additional parameters to the activation request
2. Validating the additional parameters on server-side
3. Returning an error if validation did not pass

The first thing you need to do, is to modify your REST API license activation request. Simply add a JSON object with a key named uuid and its value. It’s also important to set the Content-Type header to application/json.

Then, you will need to pass a function to the lmfwc_rest_api_validation filter. This filter takes 3 arguments. The function in that filter will look something like this:

[php]function lmfwc_tutorial_check_uuid($result, $server, $request) {
    // Not our route, nothing to do...
    if (strpos($request->get_route(), '/lmfwc/v2/licenses/activate') === false) {
        return true;
    }
​
    // Retrieve the body parameters
    $body = $request->get_json_params();
​
    // The request body was empty, or the "uuid" property is missing.
    if (!$body || !array_key_exists('uuid', $body)) {
        return new WP_Error(
            'lmfwc_rest_data_error',
            'The UUID is missing from the request.',
            array('status' => 400)
        );
    }
​
    // Obtain the license key from the request URL
    $licenseKey = explode('/lmfwc/v2/licenses/activate/', $request->get_route())[1];
​
    // Retrieve the license object
    $license = lmfwc_get_license($licenseKey);
​
    // The license was not found
    if (!$license) {
        return new WP_Error(
            'lmfwc_rest_validation_error',
            'The license was not found.',
            array('status' => 404)
        );
    }
​
    // Check if the license key already has this UUID
    $previousActivation = lmfwc_get_license_meta($license->getId(), 'activation_uuid', true);
​
    // Throw an error if that's the case
    if ($previousActivation && $previousActivation === $body['uuid']) {
        return new WP_Error(
            'lmfwc_rest_validation_error',
            'The license was already activated using this UUID.',
            array('status' => 403)
        );
    }
​
    // Hasn't been used before, proceed
    return true;
}
add_filter('lmfwc_rest_api_validation', 'lmfwc_tutorial_check_uuid', 10, 3);[/php]

We first must check if we are on the correct route. If so, the function will then retrieve all needed variables and check if they are correct. Lastly, we obtain the activation_uuid meta key from the license, and check its value against the value provided in the request body. Please note, that the meta key name can be anything, it’s up to you to define it.

Modifying Response Data

This tutorial will demonstrate how you can modify the REST API response. In this example, we will create an activation object consisting of an ID, the client proxy (should the client be using one), and the client IP address. This activation object will be stored in the license meta when the “Activate license” request has been made. The same methods and techniques shown here can be used to modify any other response. You can even remove response data, by using the PHP unset() method.

To sum everything up, we will demonstrate the following:

1. Hooking into the lmfwc_rest_api_pre_response filter.
2. Creating an activation object
3. Storing our activation object inside the license meta
4. Adding our activation object back to the response.

The process is rather simple, you need to hook into the lmfwc_rest_api_pre_response filter by using the WordPress method add_filter(). This filter takes 3 arguments. Your code would then look something like this:

[php]function lmfwc_tutorial_modify_response($method, $route, $data) {
    // First check if we are on the correct route
    if ($route !== 'v2/licenses/activate/{license_key}') {
        return $data;
    }
​
    // Now we will save an activation object for this license/activation. The
    // activation object will be an array consisting of an ID, the proxy (if
    // The remote party is using a proxy), and the user's remote address (IP).
    // Please note that we're just using the PHP "uniqid()" method for the ID,
    // you can of course use something more appropriate.
    $activation = array(
        'id' => uniqid(),
        'http_x_forwarded_for' => $_SERVER['HTTP_X_FORWARDED_FOR'],
        'remote_addr' => $_SERVER['REMOTE_ADDR']
    );
​
    // Save to the license meta
    lmfwc_add_license_meta($data['id'], 'activation', $activation);
​
    // Add the $activation variable to the response
    $data['activation'] = $activation;
​
    // Return the result
    return $data;
}
add_filter('lmfwc_rest_api_pre_response', 'lmfwc_tutorial_modify_response', 10,

Template Structure & Overriding Templates Via a Theme

License Manager template files contain the markup and template structure for frontend and HTML emails of your store.

How to Edit Template Files

Edit files in an upgrade-safe way using overrides. Copy the template into a directory within your theme named /woocommerce keeping the same file structure but removing the /templates/ subdirectory.

Example: To change the Your license key(s) heading text in the license delivery email, copy: wp-content/plugins/license-manager-for-woocommerce/templates/emails/lmfwc-email-order-license-keys.php to wp-content/themes/yourtheme/woocommerce/emails/emails/lmfwc-email-order-license-keys.php

The copied file is safe to edit and will now override the default template file.

Do not edit these files within the core plugin itself as they are overwritten during the upgrade process and any customizations will be lost.

Rest API

WordPress permalinks must be enabled at: Settings > Permalinks

To access the REST API routes, you will first need to create a pair of API keys. These API keys are used to access the REST API routes as a specific user.

Navigate to the  WooCommerce >  Settings > License Manager  > REST API keys. Here you will be presented with the following screen:

Overview of REST API keys

On this screen, press the “Add key” button at the top of the page. From here on, you will be redirected to the following form:

“Create REST API keys” form

All fields are required. The “Description” field provides a name for this REST API key pair, which should summarize what it is the keys are being used for. The “User” field is a searchable dropdown field which determines to whom these keys will be assigned to. The “Permissions” field grants the REST API keys either read, write, or read/write permissions.

After filling out the form and pressing the “Generate API key” button, you will be redirected to the following page:

REST API keys have been created

As the success message instructs, you should now store these keys somewhere safe, as this is the last time you will see the secret key. If you do not save the REST API keys, or lose them, you will not be able to recover them. Because the consumer secret is stored as a hash inside the database, it is impossible to revert. Should this occur, you will need to generate a pair of new REST API keys.

Making a Basic Request

The request URL we’ll test is wp-json/lmfwc/v2/generators. On localhost the full URL may look something like this: http://dev.wordpress.local/wp-json/lmfwc/v2/orders. Modify this to use your own site URL.

In Postman, you need to set the fields for request type, request URL, and the settings on the authorization tab. For Authorization, choose basic auth and enter your consumer key and consumer secret keys from the License Manager for WooCommerce into the username and password fields.

Once you’re done, hit send, and you’ll see the JSON response from the API if everything went well. The response should look like this:

POSTMAN window

That’s it! The API is working.

If you have problems connecting, you may need to disable SSL verification – see the connection issues section below.

401 Unauthorized

Your API keys or signature is wrong. Ensure that:

• The user you generated API keys for actually has access to those resources.
• The username when authenticating is your consumer key.
• The password when authenticating is your consumer secret.
• Make a new set of keys to be sure.

If your server utilizes FastCGI, check that your authorization headers are properly read.

Consumer Key is Missing

If you are receiving the 403 HTTP status, coupled with the lmfwc_rest_no_ssl_error error message, the plugin is refusing the request because you are not using a secure (SSL) connection. You can use the plugin settings to allow the REST API to function on insecure HTTP connections. To do so, go to License Manager > Settings

Do not disable this setting on a productive environment. Allowing the REST API to be used on insecure connections will expose your license keys to Man-in-the-Middle attacks.

Description

This route is used to retrieve all license keys from the database. Be very careful, if you do not need to use this API route in your productive environment then it is best to disable the route altogether via the settings page. The response contains an array of license key data objects.
