How should I change?
you have a solution for this code:

<?php
define('YOUR_LICENSE_SERVER_URL','https://localhost');
$api_params=array('slm_action'=>'slm_check','secret_key'=>'245454545445','license_key'=>get_option('sample_license_key'),);
$response=wp_remote_get(add_query_arg($api_params,YOUR_LICENSE_SERVER_URL),array('timeout'=>20,'sslverify'=>false));
$license_data=json_decode(wp_remote_retrieve_body($response));
global $active,$message;if($license_data->result=='success'){
?>
<?php }
else{?>
<?php wp_die(__('No License'));?><?php }?>

This is the same as the license receipt form and its validation or deactivation:

function sample_license_management_page () {
    echo '<div class = "wrap">';
    echo '<h2> Manage Template Licensing </ h2>';
    if (isset ($ _ REQUEST ['activate_license'])) {
        $ license_key = $ _REQUEST ['sample_license_key'];
        $ api_params = array (
            'slm_action' => 'slm_activate'
            'secret_key' => YOUR_SPECIAL_SECRET_KEY
            'license_key' => $ license_key
            'registered_domain' => $ _SERVER ['SERVER_NAME'],
            'item_reference' => urlencode (YOUR_ITEM_REFERENCE)
        );
        $ query = esc_url_raw (add_query_arg ($ api_params, YOUR_LICENSE_SERVER_URL));
        $ response = wp_remote_get ($ query, array ('timeout' => 20, 'sslverify' => false));
        if (is_wp_error ($ response)) {
            echo "Unexpected error! Query sent with an error.";
        }
        $ license_data = json_decode (wp_remote_retrieve_body ($ response));
        if ($ license_data-> result == 'success') {
            echo '<br /> The following message was returned from the server:'. $ license_data-> message;
echo '<br /> Licensed successfully. ';
            update_option ('sample_license_key', $ license_key);
        }
        else {
            echo '<br /> The following message was returned from the server:'. $ license_data-> message;
        }
    }
    if (isset ($ _ REQUEST ['deactivate_license'])) {
        $ license_key = $ _REQUEST ['sample_license_key'];
        $ api_params = array (
            'slm_action' => 'slm_deactivate'
            'secret_key' => YOUR_SPECIAL_SECRET_KEY
            'license_key' => $ license_key
            'registered_domain' => $ _SERVER ['SERVER_NAME'],
            'item_reference' => urlencode (YOUR_ITEM_REFERENCE)
        );
        $ query = esc_url_raw (add_query_arg ($ api_params, YOUR_LICENSE_SERVER_URL));
        $ response = wp_remote_get ($ query, array ('timeout' => 20, 'sslverify' => false));
        if (is_wp_error ($ response)) {
            echo "Unexpected error! Query sent with an error.";
        }

        $ license_data = json_decode (wp_remote_retrieve_body ($ response));

        
        if ($ license_data-> result == 'success') {// Success was returned for the license activation
            echo '<br /> The following message was returned from the server:'. $ license_data-> message;
            echo '<br /> Licensed successfully. ';
            update_option ('sample_license_key', '');
        }
        else {
            echo '<br /> The following message was returned from the server:'. $ license_data-> message;
        }
        
    }
    ?>

Please guide me

Hello
Thank you for the answer
Yes, that’s right
I want a solution after the first activation of the license
Until I send a message from my side to the customer’s site, it will not be disabled so that it will apply for approval at any time.

As long as the site (license server) is disconnected for any reason, other customer sites (WordPress template) will not be disconnected.

Thank you
