transparently capture web rest api requests and responses

[John]

I'm testing a .net service (asp mvc iis) that makes Rest API calls in https.
I would like to
1. decrypt each request and response and copy both onto disk for later searching.
2. I don't want to disrupt traffic. I want this to be transparent to the .net service and rest api service provider

Is there an extension that does this? If not, can I get pointers on what I can do to get started.

I've just completed configuring the machine.config file so that fiddler can capture all outgoing rest api requests.

nvm.

Hi John, John also here.

I have a similar quest. Not a .NET application though - but an old Delphi desktop app that has been retrofitted to make a few REST calls. I cannot figure out how to get Fiddler to capture what comes off the client. It has SOAP calls that are captured just fine - but not the REST calls. Did you find out anything on this? Thanks in advance.

Hello,

Jungwoo, I am not aware of an extension doing all that. You can do it manually by setting Fiddler as reverse proxy to capture the incoming traffic, too and then export sessions as SAZ files.

John, I am not sure I completely understand your situation. Were you successful in configuring Fiddler as a proxy to your Delphi app? I am not really an expert in Delphi but what is the chance that your app uses different APIs to make the SOAP and REST calls and the REST calls API doesn't use Fiddler as a proxy?
