square Connect API Batch - square-connect

Question

I am using .NET to list the payments from my square account.
I am able to get a list of the payments, but to get the description field I have to go one level deeper and make http end point calls for each payment. This is time consuming.
Question: Can anyone provide me with a sample in Visual C# or Java to make batch calls for retrieving payments (using multiple payment id's)?
Your help is greatly appreciated.
Thanks,
Prashant
#Andrew - Here's what I am using, I am just not sure how to add the headers for batch payments retrieval.
string res = string.Empty;
string qs = string.Empty;
foreach (string s in parameters.Keys)
{
if (qs == string.Empty)
qs = "?";
else
qs += "&";
qs += s + "=" + parameters[s];
}
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(_connectUrl + "/" + command + qs); ///
request.Proxy = null;
request.Headers.Add("Authorization", "Bearer " + _accessToken);// ");
request.ContentType = "application/json";
request.Method = method; // "GET";
try { HttpWebResponse responseGet = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(responseGet.GetResponseStream());
StringBuilder output = new StringBuilder();
output.Append(reader.ReadToEnd());
responseGet.Close();
request = null;
return output.ToString();
}
catch (Exception exp)

Looks like I've been able to answer my own query.
We need to be able to send the following POST to the HTTP Endpoint
{"requests":[{"method":"GET","relative_path":"/v1/me/payments/<payment_id>","access_token":"XXXX","request_id":"1"},{"method":"GET","relative_path":"/v1/me/payments/<payment_id>","access_token":"XXXX","request_id":"2"}]}
the following code in .NET achieves the above
//Convert the body of request into a byte array
byte[] byteArray = Encoding.UTF8.GetBytes(body);
//Set the length
request.ContentLength = byteArray.Length;
//Write the body to the request by using a datastream
//This line never returns....
Stream datastream = request.GetRequestStream();
datastream.Write(byteArray, 0, byteArray.Length);
datastream.Close();
And that's all there is to it.
Hope this helps anyone is is set out to use the batch mode.
Thanks
