PROXYMAN SETUP INSTALL

On the left hand side you can see that Proxyman sorts these connections by app which is really helpful it will also sort your phone traffic into a section of it's own once we connect it.

PROXYMAN SETUP INSTALL

Install Proxyman and launch it for the first time, you will be presented with a flow of network traffic from your own computer at first. You could use more advanced tools like Wireshark for this as well but i'll skip those for now because these are far more user friendly. There's a couple options that I know off hand one is Charles Proxy and the other, which I will use for this article is Proxyman. This is like adding a third person to the phone call that can hear what is being said. The first step is to find the right tool for inspecting traffic you will want something that can setup a proxy for your local network so that you can connect your phone to it and show your phone's network traffic. I'm going to assume that you are connected to a home internet network, you should not do this on a network you don't own, although we will only be looking for your own traffic this could be considered illegal in some areas on public networks. Since this communication happens over the internet it must bounce through several networks to get where it's going, starting with the network that your phone is connected to. You say 'I want a large cheese pizza' (request) and the person on the other end replies 'Okay that will be $20' (response). Both the request and response can contain data it's easy to visualize thinking like a phone call where you are ordering food. The typical way for this communication to happen is via HTTP requests where the app will send the backend a request and the backend will send a response. These two components are separate from each other and must communicate with each other over the interent. Today I want to dive deeper in to how this kind of thing is done to provide more of an understanding of the process.ДЇocusing specifically on mobile apps we can say that at a high level there are two components: the app and the backend.

Recently I wrote an article talking about inspecting traffic between the app for a game that I play and it's server and writing an API library to cover it's undocumented 'private' API.
