Sending parameters to /autocomplete endpoint

[tavisca-ysant]

As per the test cases for Autocomplete, we need a multiline string as input. However, I am facing issues in sending multiline WordToComplete. PFB json object:

{ "WordToComplete":"public class A { public A() { string s; s.Leng$; } }", "ForceSemanticCompletion":"true", "WantDocumentationForEveryCompletionResult":"true", "WantImportableTypes":"true", "WantMethodHeader":"true", "WantSnippet":"true", "WantReturnType":"true" }

Any help would be appreciated. I have already tried using \n and \n but with no success, it still gives as line = 0.
