webhook of type space member.remove not working in switch block

Hi

Im am working on a script that creates a logfile of members beeing added an removed from at certain workspace.

I have created a webhook on type space and the code should react and do something when member is added or removed.

It works when I add a new member but it also reads the next lines of code in the 2. Case and sends me an email from that to.

When I try to remove a member. Nothing happens. What am I doing wrong?  Here the code:

try {
 
    switch ($_POST['type']) {
                case 'hook.verify':
    
    // Validate the webhook
                PodioHook::validate($_POST['hook_id'], array('code' => $_POST['code']));
    
             case 'member.add':
                $newSpaceMember = PodioSpaceMember::get( $SPACE_ID,$_POST['user_id']);
                $date= date_create();
               
                mail($email,"Ny bruger er tilføjet",$newSpaceMember->profile->name);
               
             
             case 'member.remove':
                $date= date_create();
                $formatet_date = date_format($date,"d/m/Y");
                $removedSpaceMember = PodioSpaceMember::get( $SPACE_ID, $_POST['user_id']);
                mail("soren.norup@uudanmark.dk","Member is removede","der er blevet lavet en ny status");
                
                
                }
}
              
   catch (PodioError $e) {
    echo $e->body['error_description'];
}
