Monitor HTTPS traffic on an ios device or maybe remotely on the Internet
If you set the IP-address where Charles is running as a proxy on your iPad you should be able to catch all traffic going to your iPad.

For HTTPS you need to install the Charles Certificate on your iPad and let Charles decrypt your HTTPS traffic en encrypt it again before sending it to your iPad (man-in-the-middle). In the Charles application it's called SSL-Proxying.
