    I am very new to Fiddler and am needing some help monitoring some JSON messages. I normally use a test client from my pc to send json messages to a rest api endpoint on azure. There are various other applications sending messages to that endpoint too. How do i capture all the messages that reach the endpoint?

    Hello, Noah--

    Fiddler is a proxy; it captures everything that's sent to it. By default, it registers as the system proxy for your local PC, so that applications (like browsers, Office, etC) that use the system proxy will automatically send their traffic to Fiddler when Fiddler is "attached." Some clients (e.g. Opera, CURL, Java, etc) require manual configuration to set their traffic to proxy to

    It sounds like you might be saying: "How can I see all of the traffic received by my endpoint on Azure, including traffic on machines that haven't been configured to run Fiddler?"

    To do that, you must configure Fiddler as a reverse proxy and run it on the target server; see
