Software API Integration code example

Any software can use API functionality. We can provide full code in a form of WordPress plugin which can be used as staring base for further implementation.

This is a sample usage on a licence key activation call:

The first part of the code consist of few constants definition which are being used later within the code.

//the url where the WooCommerce Software License plugin is being installed
define('SL_APP_API_URL',      '');

//the Software Unique ID as defined within product admin page
define('SL_PRODUCT_ID',           'APTO');

$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";
define('SL_INSTANCE',             str_replace($protocol, "", get_bloginfo('wpurl')));

A simple activation calls will looks like this:

$args = array(
                    'woo_sl_action'         => 'activate',
                    'licence_key'       => $license_key,
                    'product_unique_id'        => SL_PRODUCT_ID,
                    'domain'          => SL_INSTANCE
$request_uri    = SL_APP_API_URL . '?' . http_build_query( $args );
$data           = wp_remote_get( $request_uri );

if(is_wp_error( $data ) || $data['response']['code'] != 200)
        //there was a problem establishing a connection to the API server

$data_body = json_decode($data['body']);
        if( $response_block->status == 'success' && ( $response_block->status_code == 's100' || $response_block->status_code == 's101' ) )
                //the license is active and the software is active
                //doing further actions like saving the license and allow the plugin to run

                //there was a problem activating the license
        //there was a problem establishing a connection to the API server

The API $data_body response include also a ‘message’ argument with detailed text information of the response. This is always an English text, which can be translated to the local site language using _e, __ and other WordPress translation functions.
