I wan't to override the app name when posting to facebook (it shown in each post) , I don't wan't to change the app name forever , only for the post. I know that it is possible in some way. If I change the app_name from FB I see that all the post that made with the app are changed , I only wan't to override the name for each post. Please see attached image.
You can update an Application by making a POST request to /{application_id}.

I guess you want to update the "app_name" field. As CBroe commented, it will most likely change the name for ALL posts, so it´s not possible to change it per post. Would be weird anyway.
If you just want to hide it, i suggest using the famous sharer.php - no authorization or App needed for that.
