How to write json body for multiple list items to write in a list.

Question

Hi,
I am trying to create list items using REST API, and I am reading the data from Sales force and writing it to the list. For wring sigle item its working fine, but if i am trying to insert multiple data to the list using rest API I am getting bad server requesrt
status code as 400.
 HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(args[0] + "/_api/web/lists/GetByTitle('Contacts')/items");
            request.Method = "POST";
            request.Accept = "application/json;odata=verbose";
            request.ContentType = "application/json;odata=verbose";
            request.Headers.Add("X-RequestDigest: " + requestDigest);
            request.Headers.Add("Cookie: " + cookies);
            string body = "{ '__metadata': { 'type': 'SP.Data.ContactsListItem' }, 'Title': 'Ravish', 'FirstName': 'Verma'}";
            byte[] buf = Encoding.UTF8.GetBytes(body); 
            request.ContentLength = buf.Length;
            request.GetRequestStream().Write(buf, 0, buf.Length);
            var response = (HttpWebResponse)request.GetResponse();
In the above code highlighted, line of code works fine, for single item, but if I am giving string values as 
            string body = "{ '__metadata': { 'type': 'SP.Data.ContactsListItem' }, [{'Title': 'Ravish', 'FirstName': 'Verma'},{'Title': 'Verma', 'FirstName': 'Ravish'}]}";
            string body = "{ '__metadata': { 'type': 'SP.Data.ContactsListItem' }, [{'Title': 'Amireddy', 'FirstName': 'Kishore'},{'Title': 'Amireddy', 'FirstName': 'Kishore'}]}";
            string test = "{ '__metadata': { 'type': 'SP.Data.ContactsListItem' }, 'Title': 'Amireddy', 'FirstName': 'Kishore'}";
            string body = "{ '__metadata': { 'type': 'SP.Data.ContactsListItem' }, 'Title': 'Ravish', 'FirstName': 'Verma'}";
All the above format give bad server request.
if any one has the idea to send multiple items in the request body, please provide me the sample code.
Thanks in Advance.

The SharePoint 2013 REST API does not support "batch" or multiple inserts in one call at this time.
