How do you get deleted text messages from the server
How do you get deleted iMessages back?
You don't. Text messages are not saved on any server. They are only on your phone. If you have iCloud sync for messages enabled when you delete a message from your phone it is also deleted from iCloud. The only possibility is if you do not have iCloud sync enabled for messages. In this one case a backup that contains the deleted texts can be restored to your phone. But that will overwrite everything on your phone, not just the missing texts.
