{eac}SoftwareRegistry is a derivative plugin of and requires installation and registration of {eac}Doojigger.


{eac}SoftwareRegistry is a WordPress software licensing and registration server with an easy to use API for creating, activating, deactivating, and verifying software registration keys.

Registration keys may be created and updated through the administrator pages in WordPress, but the system is far more complete when your software package implements the {eac}SoftwareRegistry API to manage the registration.

One of two scenarios typically occur when a client receives your software:

  1. The client purchases your software, registers your software, then installs your software.

    With {eac}SoftwareRegistry, a new registration key may be created through the purchase process (or manually by the administrator) and then the client may enter the registration key and activate the registration when installing the software.

  2. The client downloads your software, installs your software, and then registers your software.

    The client is presented with a "new registration" screen when installing the software and may request a new registration key through the API which will automatically generate the key and activated the registration.

Registration keys may be verified via API on a scheduled basis so that any updates made by the administrator, via other transaction, or due to renewal or expiration, are updated in the client software.

Registration status may be:

  • Pending (awaiting approval)
  • Trial (limited time trial period)
  • Active
  • Inactive
  • Expired
  • Terminated

Registrations may include (but do not require):

  • Valid domain(s).
  • Valid site URL(s).
  • Number of users/sites/devices.
  • License level (i.e. 'basic', 'pro').
  • Software product-specific options and variations.

{eac}SoftwareRegistry API

The built-in Application Program Interface (API) is a relatively simple method for your software package to communicate with your software registration server ({eac}SoftwareRegistry).

See the API Details section.

{eac}SoftwareRegistry Distribution SDK

The added {eac}SoftwareRegistry Software Distribution Development Kit (SDK) extension makes it even easier to implement software registrations in your software package.

With the inclusion of the SDK generated for your package, you may be able to implement the APIs for {eac}SoftwareRegistry with only a small amount of code.

The SDK includes everything needed to create, activate, deactivate, revise, and refresh a registration. It also includes the storing of the registration key, the caching of the registration data, and the scheduling of verification requests.

Both WordPress and non-WordPress projects are supported by the SDK.

{eac}SoftwareRegistry Custom Hooks

With the {eac}SoftwareRegistry Custom Hooks extension, you can add custom PHP code for the many hooks (filters and actions) available in the server software. With these hooks you can customize the registry server options, incoming API requests, outgoing API responses, and client emails and notifications.

{eac}SoftwareRegistry and WooCommerce

With the added {eac}SoftwareRegistry WebHooks for WooCommerce extension, software registrations can be created, updated, and/or terminated via WebHooks from WooCommerce.

A Webhook is an event notification sent to a URL of your choice. Users can configure them to trigger events on one site to invoke behavior on another.

Simply create the needed webhooks in the WooCommerce administration (order created, order updated, order deleted, order restored) and enable the corresponding end-points in {eac}SoftwareRegistry.

When an order placed on your WooCommerce site is created, the registration will be created on your software registration server. If the customer updates or cancels their order, their registration will also be updated or cancelled.

Your WooCommerce and registration server do not need to be the same server and neither needs to be running the other software. In fact, you can have multiple WooCommerce sites all sending webhook updates to your registration server.

{eac}SoftwareRegistry Subscriptions for WooCommerce

Go one step further by adding the {eac}SoftwareRegistry Subscriptions for WooCommerce plugin to your WooCommerce store site and subscription updates will also be passed to your registration server keeping your registrations updated by your subscription renewals.

API Details

First, from the Distribution tab of the Software Registry Settings, you will need your API keys and Endpoint URL.

API parameters

API parameters are passed as an array:

$apiParams =
    'registry_key'          => 'unique ID',                     // * registration key (assigned by registry server)
    'registry_name'         => 'Firstname Lastname',            //   registrant's full name
    'registry_email'        => 'email@domain.com',              // * registrant's email address
    'registry_company'      => 'Comapny/Organization Name',     //   registrant's company name
    'registry_address'      => 'Street\n City St Zip',          //   registrant's full address (textarea)
    'registry_phone'        => 'nnnnnnnnnn',                    //   registrant's phone
    'registry_product'      => 'productId',                     // * your product name/id ((your_productid))

    'registry_license'      => 'Lx',                            //   'L1'(Lite), 'L2'(Basic), 'L3'(Standard), 'L4'(Professional), 'L5'(Enterprise), 'LD'(Developer)
    'registry_count'        => int,                             //   Number of licenses (users/seats/devices)
    'registry_variations'   => array('name'=>'value',...),      //   array of name/value pairs
    'registry_options'      => array('value',...),              //   array of registry options
    'registry_domains'      => array('domain',...),             //   array of valid/registered domains
    'registry_sites'        => array('url',...),                //   array of valid/registered sites/uris
    'registry_transid'      => '',                              //   external transaction id
    'registry_timezone'     => '',                              //   standard timezone string (client timezone)

API Remote Request

Example code to execute the remote request

 * remote API request - builds request array and calls api_remote_request
 * @param   string  $endpoint create, activate, deactivate, revise, verify
 * @param   array   $params api parameters
 * @return  object api response (decoded)
public function registryApiRequest($endpoint,$params)
    $endpoint = strtolower($endpoint);
    switch ($endpoint)
        case 'create':
            $apiKey = "<Registration Creation Key>";
            $method = 'PUT';
        case 'activate':
        case 'revise':
            $apiKey = "<Registration Update Key>";
            $method = (count($params) > 1) ? 'POST' : 'GET';
        case 'deactivate':
            $apiKey = "<Registration Update Key>";
            $method = 'DELETE';
        case 'verify':
            $apiKey = "<Registration Read Key>";
            $method = (count($params) > 1) ? 'POST' : 'GET';

    $request = [
        'method'        => $method,

    $request['headers'] = [
        'Accept'        => 'application/json',
        'Referer'       =>  sprintf('%s://%s%s', isset($_SERVER['HTTPS']) ? 'https' : 'http', $_SERVER['HTTP_HOST'], $_SERVER['REQUEST_URI']),
        'Authorization' => 'Bearer '.base64_encode($apiKey),
    if (in_array($method,['GET','HEAD','DELETE'])) {
        $request['headers']['Content-Type'] = 'text/plain';
        $remoteUrl = "<API Endpoint URL>".'/'.$endpoint .'?'. http_build_query($params);
    } else {
        $request['headers']['Content-Type'] = 'application/json';
        $request['body'] = json_encode($params);
        $remoteUrl = "<API Endpoint URL>".'/'.$endpoint;

    $response =  $this->api_remote_request($endpoint,$remoteUrl,$request);

    if ($response->status->code == '200') && $endpoint != 'deactivate' && isset($response->registration))
        // update the current registration cache (save the registration object and key)
        // schedule the next refresh event
    return $response;

 * API remote request - remote http request (wp_remote_request or curl)
 * @param   string  $endpoint create, activate, deactivate, verify
 * @param   string  $remoteUrl remote Url
 * @param   array   $request api request
 * @return  object api response (decoded)
public function api_remote_request($endpoint,$remoteUrl,$request)
    $result = wp_remote_request($remoteUrl,$request);
    $body   = json_decode(wp_remote_retrieve_body($result));
    if (!empty($body) && isset($body->code) && isset($body->message)) {
        $result = new \wp_error($body->code,$body->message,$body->data);

    if (is_wp_error($result))
        $code   = $result->get_error_data() ?: [];
        $code   = $code->status ?? $result->get_error_code();
        $msg    = $result->get_error_message();
        $error  = json_decode('{"status":{"code":"'.$code.'","message":"'.$msg.'"},'.
        return $error;

    return $body;

Using registryApiRequest()

Create/request a new registration...

$response = $this->registryApiRequest('create',$apiParams);

Activate an existing registration...

$response = $this->registryApiRequest('activate',['registry_key' => "<registration_key>"]);

Deactivate an existing registration...

$response = $this->registryApiRequest('deactivate',['registry_key' => "<registration_key>"]);

Verify/Refresh an existing registration...

$response = $this->registryApiRequest('verify',['registry_key' => "<registration_key>"]);

Revise an existing registration...

$response = $this->registryApiRequest('revise',$apiParams);

API Remote Response

The API response is a standard object. status->code is an http status, 200 indicating success.

status      ->
    'code'                  -> 200,             // HTTP status code
    'message'               -> '(action) ok'    // (action) = 'create', 'activate', 'deactivate', 'verify', 'revise'
