Q) How can I capture the API URL of smartphone application ?
A) To capture the API URL of a smartphone application, you will need to use a tool called a network sniffer or packet capture tool.
This type of tool intercepts and captures the network traffic between your smartphone and the application's server, allowing you to inspect the requests and responses that are sent and received.
There are many network sniffer and packet capture tools available, both for desktop and mobile platforms. Here are some popular options:
- Wireshark: a desktop tool that can capture network traffic on a variety of platforms, including Windows, macOS, and Linux.
- Fiddler: a desktop tool that can capture and analyze HTTP and HTTPS traffic on Windows.
- Charles Proxy: a desktop tool that can capture and analyze HTTP and HTTPS traffic on macOS, Windows, and Linux.
- Burp Suite: a desktop tool designed for web application security testing, but can also be used to capture and analyze network traffic on Windows, macOS, and Linux.
- mitmproxy: a command-line tool that can capture and intercept HTTP and HTTPS traffic on a variety of platforms, including Windows, macOS, and Linux.
To use these tools, you will need to set up a proxy on your smartphone that directs all network traffic through the tool. This can be done by configuring the Wi-Fi settings on your smartphone to use a manual proxy configuration and specifying the IP address and port of the tool.
Once you have set up the tool and captured the network traffic, you can inspect the requests and responses to identify the API URL used by the application.
This may involve looking for specific patterns in the network traffic, such as requests to a particular domain or requests that contain certain headers or parameters.
