please do yourself a favor and remove yourself your credentials for accessing the service. change the password. best regards.

You set the method to POST, but that looks rather like a GET.
On the other hand, many web servers do not care for the method...

if you see at api defination it is type of POST.

The 400 Bad Request error is an HTTP status code that means that the request you sent to the website server (e.g. a request to load a web page) was somehow malformed therefore the server was unable to understand or process the request.

Check for errors in the URL. The most common reason for a 400 Bad Request error is because the URL was typed wrong or the link that was clicked on points to a URL with some kind of mistake in it.

I would go with the following below, and test sBaseUrl in the browser address bar, I think it's the encoding needs to be encoding.utf8, and perhaps the folder token doesn't have a default page for the querystring to attach to.

C#

sBaseUrl = httputility.Urlencode(sBaseUrl + sParameter, encoding.utf8);

Solution 3

400 Bad request exception will cause due to the wrong authentication.
1. check the url which you are sending is valid.
2. check the username and password is write.

note: check whether your leaving any spaces. while copying the contents
