|Profiling an application is a technical process. This is best completed by a developer or other technical resource.
|If you are attempting to find Channel IDs and have an Airship account level that includes technical support contact, please contact Airship Support for a token that will allow easier access to the Channel ID with Airship SDK 6.1 or later.
|Because Charles Proxy exposes encrypted traffic to a 3rd party (in this case your computer), there are security concerns inherent in its use. We recommend using only Test Devices with Charles Proxy, and removing the Charles Proxy SSL Certificate after using Charles Proxy. Instructions for certificate removal are included at the bottom of this article.

Removing the Charles Certificate from your device
Charles Proxy is a useful tool because it allows you to view HTTPS encrypted traffic that passes in and out of your device by installing a CA Certificate.
However, this certificate can allow others to view encrypted traffic from your device.
|For security reasons, we highly recommend that you remove the CA Certificate from your device after you are done using Charles Proxy. It is also a Best Practice to use Charles Proxy only with dedicated test devices.
