Hello again @drazenbebic.
With the code I gave you as an example, it works for me, but I wanted to know if there is any other way to make it safer.

Thank you!????

If you can give me an example of the best form of implementation, it would be helpful

hello again @drazenbebic
I hope you’re well, I still need your help, I’m a little stuck with the plugin

And to verify the license I have something like that

$msg ='';
$result = '';
$api_params = array(
    'consumer_key' => WFS_CONSUMER_KEY,
    'consumer_secret' => WFS_CONSUMER_SECRET,
);

$url_params = WFS_LICENSE_SERVER_URL;
$url_params .= urlencode( get_option( 'wfs_license_key' ) );

$query = esc_url_raw( add_query_arg( $api_params, $url_params ) );
$response = wp_remote_get($query, array('timeout' => 20, 'sslverify' => true));

if ( is_array( $response ) && ! is_wp_error( $response ) ) {

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

    if( isset( $license_data->success ) &&  $license_data->success == 1 ) {

        $current_date = strtotime(date("Y-m-d H:i:00",time()));
        $expires_date = strtotime($license_data->data->expiresAt);

        if ( isset( $license_data->data->licenseKey) && strcmp ( $license_data->data->licenseKey, get_option('wfs_license_key') ) == 0 && $current_date < $expires_date ) {

            $result .= $license_data->data->licenseKey;

            $msg .= __( 'your license will be active until:' );
            $msg .= ' '. $license_data->data->expiresAt;

        }

    } else{

        $msg .= __( 'Invalid License' );
    
    } 

} else {

    $msg .=  __( 'something did not go well when reading the license' );

}

Hello again @drazenbebic.
Thank you for responding so quickly, the idea is to make a freemium add-on. I am new to this world, so I cannot think of another way to do a verification, I know it is very easy to avoid, is there any other way to make it more difficult?
would something like this be activated or deactivated?

 <?php 

if ( isset( $_REQUEST['activate_license'] ) || isset( $_REQUEST['deactivate_license'] ) ) {

    if ( ! wp_verify_nonce(  $_REQUEST['wfs_license_nonce'], 'wfs_license_nonce' ) ) {

        wp_die("Error - Invalid nonce verification ?");

    }else {

        $license_key = sanitize_text_field( $_REQUEST['wfs_license_key'] );             

        if ( isset( $_REQUEST['activate_license'] ) ) {

            $license_action = 'activate/';

        }elseif ( isset( $_REQUEST['deactivate_license'] ) ) {

            $license_action = 'deactivate/';
        }

        $api_params = array(
            
            'consumer_key' => WFS_CONSUMER_KEY,
            'consumer_secret' => WFS_CONSUMER_SECRET,
        );

        $url_params = WFS_LICENSE_SERVER_URL;
        $url_params .= $license_action;
        $url_params .= urlencode($license_key);

        $query = esc_url_raw( add_query_arg( $api_params, $url_params ) );
        $response = wp_remote_get($query, array('timeout' => 20, 'sslverify' => false));

        if ( is_array( $response ) && ! is_wp_error( $response ) ) {

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

            if( 1 == $license_data->success ){

                if ( isset( $_REQUEST['activate_license'] ) ) {

                    update_option( 'wfs_license_key', $license_key ); 

                }elseif ( isset( $_REQUEST['deactivate_license'] ) ) {

                    update_option( 'wfs_license_key', '' ); 
                }

            }else{

                $msg .= $license_data->message;
            }
        }else {

            _e( 'something did not go well when reading the license');
        }

    }
}

?>
<form action="" method="post" style="width:100%;">
    <?php wp_nonce_field( 'wfs_license_nonce', 'wfs_license_nonce' ); ?>
    <div class="content-label-share">
        <label class="label-share">
            <p class="label-p"><?php _e( 'License Key' ); ?></p>
            <input class="input-share" type="text" id="sample_license_key" name="wfs_license_key"  value="<?php echo get_option('wfs_license_key'); ?>" >
            <?php if ( !empty( $msg ) ) { echo '<p>'.$msg .'</p>'; } ?>
        </label>
    </div>  
    <p class="submit">
        <?php submit_button( __( 'Activate' ), 'primary', 'activate_license', false, array( 'id' => 'wsf-activate-license-id' ) ); ?>
        <?php submit_button( __( 'Deactivate' ), 'delete', 'deactivate_license', false, array( 'id' => 'wsf-deactivate-license-id' ) ); ?>
    </p>
</form>     
<?php 

Thanks for the help
