Any help is highly appreciated

please follow this guide for creating a new UI component backend. https://www.mageplaza.com/devdocs/creat-a-ui-form-in-magento-2.html

Once the UI component is created, check here how you create your custom source data: https://devdocs.magento.com/guides/v2.4/ui_comp_guide/concepts/ui_comp_data_source.html

Your custom suorce data should not be a standard collection, but it will have to call a class that executes the specific curl call you need. This data will then be injected through the dataProvider.

It is not easy to explain it is a complex process if developed according to magento specifications


  • yes this seems to be the right approach have implemented something similar Aug 5, 2020 at 17:55

For this you had to install a module. Declare a public URL in the module. access that URL and inside the "execute" function of controller, call external rest API with curl command.


namespace vendorname\modulname\Controller;

class Fetchdata extends \Magento\Framework\App\Action\Action
    protected $_pageFactory;

    public function __construct(
        \Magento\Framework\App\Action\Context $context,
        \Magento\Framework\View\Result\PageFactory $pageFactory)
        $this->_pageFactory = $pageFactory;
        return parent::__construct($context);

    public function execute()
        //execute Curl call to external rest api here.
        $curl = curl_init();
        curl_setopt_array($curl, array(
          CURLOPT_URL => "http://api.minetools.eu/ping/play.desnia.net/25565",
          CURLOPT_TIMEOUT => 30,
          CURLOPT_HTTPHEADER => array(
          "cache-control: no-cache"

       $response = curl_exec($curl);
       $err = curl_error($curl);


        //than push response from curl call to insert data into grid table 
        //using mysql query

        $this->_resources = \Magento\Framework\App\ObjectManager::getInstance()
       $connection= $this->_resources->getConnection();

       $themeTable = $this->_resources->getTableName('yourtablename');
       $sql = "INSERT INTO " . $themeTable . "(field1, field2) VALUES ('1', 'NameABC')";

for publick URL, you can use this file.


<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
    <router id="standard">
        <route id="fetch_rest_api_data" frontName="fetch_rest_api_data">
            <module name="vendorname_modulename" />

Now in browser, run this url http://yourmagentourl.com/fetch_rest_api_data/fetchdata i-e http://yourmagentourl.com/RoutFrontName/ControllerName
