Close Payment Batch Synchronously not working properly

I am new to SAP Concur Expense service. I am trying to close Payment Batches by calling the Concur API through my ASP.NET C# project. I am trying to do this in 3 steps by following the documentation 


  1. Close a Payment Batch Asynchronously ( POST /api/expense/paymentbatch/v1.2/batch/{BatchID}/close )
  2. Then close the Payment Batch Synchronously ( POST /api/expense/paymentbatch/v1.1/batch/{BatchID}/close )
  3. Finally, Retrieve the Payment Batch File ( By calling the File-Url returned by the Close Batches 1.1 API response from the 2nd step )

Sometimes, I face problems from step 2 (Close Payment Batch Synchronously). In this step, I don't get any successful response (response doesn't contain file URL), but the Payment Batch status changes and shows CLOSED. I can get SUCCESS status when I call the same API multiple times (2-10 times). 


Following are the two ways I tried to perform step 2:

string url = "{UrlPrefix}/api/expense/paymentbatch/v1.1/batch/{batchId}/close";
Client = new HttpClient(); //HttpClient declared globally
Client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
Client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", {accessToken});
var body = new List<KeyValuePair<string, string>>();
HttpContent content = new FormUrlEncodedContent(body);
HttpResponseMessage postResponse = await Client.PostAsync(url, content);


string url = "{UrlPrefix}/api/expense/paymentbatch/v1.1/batch/{batchId}/close";
HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Post, url);
requestMessage.Headers.Add("Authorization", "Bearer " + {accessToken});
requestMessage.Headers.Add("Accept", "application/json");
HttpResponseMessage postResponse = await Client.SendAsync(requestMessage); //HttpClient Client = new HttpClient() declared globally


In both scenarios, sometimes I get [postResponse.IsSuccessStatusCode = false] response. I tried to find the root cause of this problem but didn't find any.


If anyone has faced the same problem or knows any solution to the problem, please let me know.
