Make external request after saving

Hi, when user saves changes in visual editor, i need to send a request to external page.

I’m trying this approach but not getting success. Some help?

function elementor_save_camps($post_id, $editor_data){
    $url = 'https://externalsite/?url='.get_permalink($post_id);
    $r = wp_remote_get( $url ); // tried this too wp_remote_head($url)
}
add_action( 'elementor/editor/after_save', 'elementor_save_camps');

I’m adding this to my theme functions.php

When clicking on save button of visual editor, data is saved normally in wp database but the request is not made 🙁

Kind regards.
