Fiddler 401 error /_api/web

Question

I am requesting this url with fiddler: http://sitecollectionUrl/_api/web

With the header of:

Accept:   application/json;odata=verbose

But I am getting 401 error code when doing so. I am on SharePoint Server 2013.

Have you checked Automatically Authenticate option or you have key in the Authorization in header? — Mark L, Dec 16, 2015 at 2:21
How do I check the authentication automatically? No I don't have a header for authentication. — Brittany Rutherford, Dec 16, 2015 at 6:06
Thank you Mark, I found the automate authentication, and it worked. Please add it as answer so I can mark it :) thank you a lot — Brittany Rutherford, Dec 16, 2015 at 6:11

You can enable the Automatically Authenticate option in Fiddler. It will use your current Windows logon account to send the request.

The option can be found under Composer tab > Options tab
