How to Inspect Live iOS App Network Traffic // Charles Proxy

This video will teach you how to use Charles Proxy to monitor and analyze iOS app network traffic. Charles Proxy is a popular Mac OSX application that can be used for monitoring, intercepting, and modifying HTTP requests. It also monitors HTTPS traffic by decrypting the SSL/TLS connections so it can view both the plaintext data as well as any cookies or passwords in those packets.

It's especially helpful for catching bugs in your code, finding security vulnerabilities before they're exploited, debugging issues with third-party integrations (e.g., ads), and understanding why users are having problems using your app.

Charles is a powerful program that will allow us to see all the data being sent between our device and the internet. We'll be able to identify any issues with security or performance, as well as track down bugs if we've ever been frustrated by something not working before!

For the newer iOS versions, the "Profile" setting is now located inside "VPN & Device Management", in case you can't find it 👍Amazing video my friend, thank you so much!!!!

Great video that demonstrated how to actually use charles, as there are already tons of configuration videos out there, but I couldn't find anything that shows me how to quickly enable SSL proxy for a certain domain, and also how to inspect the responses. Thanks.

[carapungo]

this was good, however you forgot to mention how to configure the charles proxy on the mac itself, this is a very important

[LuisTCarbonell]

Thank you, great video ! it works for me.

Does the app need to in debug mode? Can i get the live app from app store n able to do see http trafic? Needed in sight on it

Hello, thx for the video it really helped me. Though I am trying to analyse requests of one specific app on my iPhone. I can detect everything but as soon as I turn on the ssl proxying for that domain, the app stops working. After some research I have figured out that the app used something called ssl pinning. Is there anyway to bypass it easily without jailbreaking my iPhone or another way of analyzing encrypted requests made by the app on Charles Proxy?

[cristianblanco]

Hey! Nice video.
Do you know if there is anyway to export the traffic in a HAR file or something similar? Or is there any other tool you know that can do it?

[shinaboy]

It’s possible to bypass forced update app using Charles proxy ? Is there a work around . I want to keep my old app but is asking me to update new version in order to go online .

[tzuuyaolee]

thx. but I still seeing "unknown" after "Enable SSL Proxing" + refresh, do u know why?

[bittusharma]

internet is not working on my iphone after adding manual proxy in wifi setting. Any Solution?

[dgamah]

When i close the charles app on my macbook i cannot visit websites on my phone anymore. It says: “Safari can’t open the page because Safari can’t connect to the server.” How can i run the traffic on the app and visit websites on my iphone while the charles app or my macbook is closed?

Hi, so I've been trying to get Charles to work on my Windows computer to pick up iOS network calls. I can get the calls for windows to come through for the web, but I can't get my mobile iOS device calls to come through. It seems like every time I try the manual proxy on my phone, there doesn't seem to be any internet connection in order for me to move further with downloading the appropriate certificate. I downloaded the certificate a different way by downloading it on the computer and sending it to my iOS device and opened it from there. Not sure if this is alright? The lingering issue is still 1)no internet connection 2)calls not coming through from the mobile device. Can you help me?

[anshulbali]

hey i am doing the same as you mentioned on the video but my iPhones internet stops working. i tried many time even i tried automatic proxy configuration mentioned on charles website! could you suggest me what to do?

[kaisertushar]

I want to mention one thing here. You need to have Mac to intercept iPhone requests through Charles. I used Linux PC and my iPhone won't get an internet connection through Proxy.

[ApoorvaDhavale]

How will you reverse engineer this app?
Please explain

You cannot see the path of the encrypted https. The only thing visible is the domain name due to SNI. Also, your request failed because you hasn't put the URL into single quotes.
