I have created a WCF RESTful service in SharePoint 2010 and it's working as expected for all the POST methods in Postman, whereas the same run from Fiddler generates authentication error.
I have searched on a couple of forums for the solution and one of the solutions was to go with Form Digest value via the following POST call :
<>/_api/contextinfo with header values as
ACCEPT: application/json;odata=verbose Content-Type: application/json;odata=verbose Host: sitename Content-Length: 196
Ths issue here is this call itself is rendering a 404 not found exception. Unable to find an appropriate solution to the actual issue.
Please help me out !!
