Rough outline of installing transport packages via the CLI

modx.package-install.php

<?php
        $path_to_modx = '/var/www/modx';
        define('MODX_API_MODE',true);
        require $path_to_modx."/index.php";
        /** @var \modX $modx */
        
        // Download Details
        /** @var string $package_url  - URL from the orange 'Download' button on the MODx Extras website */
        $package_url = 'http://modx.com/extras/download/?id=512403a2f245547611000025'
        $package_signature = 'getresources-1.6.0-pl'
        
        // Download the package
        $modx->runProcessor('workspace/packages/rest/download',array(
                        'info' => $package_url.'::'.$package_signature
                ));

        // Create modTransportPackage object in new modx install
        $scan = $modx->runProcessor('workspace/packages/scanlocal');

        // Run install command
        $response = $modx->runProcessor('workspace/packages/install',array(
                'signature' => $package_signature
            ));

Hi @alanpich, thx for that snippet of code, it was useful ;)
