     Dear all,

I downloaded now fre (without paying) Fiddler to do some post tests, but as now I don't know how to enter username and password to authenticate to web service address, that was given to me. As I'm new completely to Fiddler, can anyone help me, please? I read that I need to enter Tools and something else, but I don't find it. Is tools menu under payments?

 

Thanks

 

Francesco

Hi,

 

The classic Fiddler is a free tool, and there are no paid functionalities. The new Fiddler Everywhere has a PRO plan which provides sharing/collaboration capabilities, but again the core functionalities are available with the free tier (there are some quotas). From your post, it looks like you are trying to compose a request to an endpoint that requires authentication. If that is the case, you could use this KB article to see how you could achieve that with Fiddler Everywhere (the article is for Fiddler Eevrywhere but the same concept can be applied in the classic Fiddler).

Thanks for your reply. But I have a question: how can I use NTLM authentication? Even because I need to do a post

 

Best regards

Hello Fra,

 

You could try the approach described in this blog post  (for the classic Fiddler)

As I know I can't use NTLM auth using only Fiddler everywhere. And I don't think that curl is usable using Fiddler

Hi Fra,

 

Indeed, the NTLM uses UPD while Fiddler is a tool that is working over TCP and more specifically can capture only HTTP/HTTPS/FTP traffic.
