Created Unassigned: Cannot Parse JSON From SpringPad [24573]

I have successfully connect to SpringPad API through OAuth for my C# application, the return json were escaped by DeDefined.OAuth library based on my observation. I have escape the string and below json string (in pastebin) have been produce except the " (double quotation) were not escape because its nature of C# string to aware of the double quote. But im still got below error:

> Error reading JObject from JsonReader. Current JsonReader item is not an object: StartArray. Path '', line 1, position 1.

Return JSON

Is there a proper way to handle deserialize json from server response?
