check POST request with Fiddler

Question

How can I use Fiddler to check the response from a web server. I could easily check the GET method by pasting the url to the field in Request Builder and get the response back in xml/json. There is an option POST, however I don't know how can I pass the parameters to the POST.

For example:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.google.com/accounts/ClientLogin");
request.Method = "POST";

string postData = "accountType=HOSTED_OR_GOOGLE";
postData += "&Email=yourusername@gmail.com";
postData += "&Passwd=yourpassword";
postData += "&service=finance";
postData += "&source=test-test-.01";

How can I pass my Data into this POST method in Fiddler to get the response?

Answer 1

The simplest way to do this is to have Fiddler capture an instance of this request and drag/drop that session onto the Request builder.

But generating a post yourself isn't hard. Set the RequestBuilder's method to POST, add a header:

Content-Type: application/x-www-form-urlencoded

And put in the Request Body the text of the post:

accountType=HOSTED_OR_GOOGLE&Email=yourusername@gmail.com&Passwd=yourpassword&service=finance&source=test-test-.01
