I'm trying to learn about the API that my Amazon Echo device uses when I ask Alexa for information.

So I'd like to be able to run my Echo traffic through Fiddler (classic or everywhere).

But everything I've read requires using a browser or configuring a proxy on the remote device or some other step that I can't do on my Amazon Echo.

So is there some way to configure Fiddler to work in the scenario where I can only do stuff (e.g., VLANs, port mirroring) on an AP/PC-as-hotspot/gateway/router?

Im supporting multiple users who are all reporting that something has changed recently and while they can capture network traffic in Google Chrome and Microsoft Outlook they only get network calls from Fiddler. Tested with VPN and endpoint protection enabled/disabled. Logs captured, screen recordings available if needed.

Environment - Fiddler is deployed using Jamf with extension and proxy.

MacOS - Multiple versions 14.7.X and 15.X

Logs have multiple entries like this

error 09:22:08.150612+0000 com.progress-telerik.fiddler.fiddler-extension (3348778651): No interface found for (edited IP removed), not re-setting the interface

error 09:22:08.242428+0000 com.progress-telerik.fiddler.fiddler-extension (1259812390): No interface found for (edited IP removed), not re-setting the interface

There are some sites like this https://vk.com/ that just because fiddler is open makes the site loop the capcha challenge and not stop doing it. How to resolve this? Thanks.

Video Explaining My Issue


I was trying, as a test run, to capture the traffic from Facebook. I did what someone suggested in my previous post about removing the "https" and just using "facebook." I did that, clicked "Actions," and selected "Run Filter Set Now." I then refreshed the tab I was currently on, which was Facebook, and as you can see in the video link, no traffic was captured.

So, what am I supposed to do if I want to capture only the tab with Facebook traffic ? Do I really have to close my Firefox window, reopen Firefox, and have just one tab open with Facebook? Then, I would use Fiddler Classic. How is this realistic at all?

If anyone can please inform me how I can capture all of Facebook's traffic in the session list without any other traffic being captured-thus sparing me the hassle of sorting through the list to identify which traffic belongs to Facebook- that would be great. Otherwise, I see no reason to continue using Fiddler Classic or to subscribe.

I filtered to show only if the URL contains, as you can see in the image, but no URLs from Facebook are being listed when I refresh the tab that's currently on the Facebook URL.

Here's the error message it told me to paste onto here. I have tried uninstalling and reinstalling Fiddler but nothing changed.

I have tried editing the rules on fiddler script editor
static function OnBeforeRequest(oSession: Session) {
// Check if the request URL matches a pattern (for example, you can forward requests to a specific domain)
if (oSession.url.Contains("example.com")) {
// Get the request body (as a string)
var requestBody = oSession.GetRequestBodyAsString();

// Parse the request body as JSON
var data = parseJSON(requestBody);

if (data == null) {
// If the data is not valid JSON, handle the error
oSession.ResponseBody = "Invalid JSON received";
oSession.oResponse.headers["Content-Type"] = "text/plain";
return;
}

// Prepare the data to send to the PHP server
var dataToSend = {
"method": oSession.oRequest.headers["Method"],
"url": oSession.url,
"headers": oSession.oRequest.headers.ToString(),
"body": data
};

// Define the PHP server URL (running on localhost:8000)
var phpServerUrl = "http://localhost:8000/process_request.php";

// Prepare HTTP request to send to the PHP server
var oHTTP = new HTTPRequest(phpServerUrl, "POST", stringifyJSON(dataToSend));

// Send the request
var oResponse = oHTTP.Send();

// Handle the PHP server's response
if (oResponse.StatusCode == 200) {
oSession.ResponseBody = oResponse.Body;
oSession.oResponse.headers["Content-Type"] = "application/json";
}
}
}

But the code doesnt work because JSON object is not recordgnized.
Is there any waY I can broadcast/forward all requests captured that belong to example.com domain?>

i can't find snapshots menu in mac fiddler app. where is it?

i'm using free account now.

I disabled System proxy and tried to enable "Network Capture" with basic settings, but it's keep spinning and not enabling this feature.

If anyone can help me figure this out that will be so helpful.

Thank you

I often change computers at work, when I installed fiddler everywhere on the new computer, I saw a warning about the increase in the number of installations. How to reset it?
