function make_charge( $post_id ) {

    require_once('vendor/autoload.php');

    if( is_admin() ) {
        return $post_id;
    }

    Stripe::setApiKey('STRIPE SECRET KEY');
    
    // Get the ACF field(s)
    $cost = $_POST['acf']['REPEATER HEY IF IN A REPEATER']['THE FIELD KEY'];
    
    $token = $_POST['stripeToken'];
    
    $charge = Charge::create([
        'amount' => '$cost',
        'currency' => 'cad',
        'source' => $token,
        'description' => 'CAN BE ANYTHING'
    ]);
    
    // SENDING THE EMAIL
    // Email vars
    $to = 'EMAIL';
    $subject = 'THE SUBJECT';
    $body = 'THE BODY';

    // Send email
    wp_mail($to, $subject, $body);

    return $post_id;
}
add_filter('acf/pre_save_post' , 'make_charge', 10, 1 );

  <!-- A Stripe Element will be inserted here. -->
</div>

<!-- Used to display form errors. -->
<div id="card-errors" role="alert"></div>
