I am trying to Query for all invoices with open balances using IPP but I keep on getting 0 results back. Am I doing something wrong in code?
Here is my C# code snippet that I am trying to do with the applied Filtering
InvoiceQuery qboInvoiceQuery = new InvoiceQuery();
int iMaxPageNumber = QUERY_MAX_PAGE_NUMBER; // A Constant with the Maximum Page Number allowed in a query
int iResultsPerPage = QUERY_MAX_NUM_PER_PAGE_INVOICE; // A Constant with the Maximum Results per page
// Paging Information
qboInvoiceQuery.PageNumber = QUERY_START_PAGE_NUMBER;
qboInvoiceQuery.ResultsPerPage = iResultsPerPage;
#region Query Filtering
//////////////////////////////////////////////
// initial filtering via Query Criteria //
//////////////////////////////////////////////
// Get only Open (Unpaid) Invoices
qboInvoiceQuery.OpenBalance = (decimal)0.00;
qboInvoiceQuery.SpecifyOperatorOption(FilterProperty.OpenBalance, FilterOperatorType.AFTER);
//////////////////////////////////////////////
// END initial filtering via Query Criteria //
//////////////////////////////////////////////
#endregion
// Complete the Query calls to build the list
IEnumerable<Invoice> results = qboInvoiceQuery.ExecuteQuery<Invoice>(_ServiceContext);
IEnumerable<Invoice> qboInvoices = results;
int iCount = results.Count();
while (iCount > 0 && iCount == iResultsPerPage && qboInvoiceQuery.PageNumber <= iMaxPageNumber)
{
qboInvoiceQuery.PageNumber++;
results = qboInvoiceQuery.ExecuteQuery<Invoice>(_ServiceContext);
iCount = results.Count();
qboInvoices = qboInvoices.Concat(results);
}
*** UPDATE ***
I have implemented peterl's answer and now have the following code. However I am now running into a new problem that my code is always returning the default of 10 invoices and is not taking into consideration my body. Even if i set it to a different page number or ResultsPerPage value I was get back the first page and 10 results. Any ideas?
private Dictionary<string, Invoice> GetUnpaidInvoicesDictionary(IdType CustomerId, bool bById = true)
{
Dictionary<string, Invoice> dictionary = new Dictionary<string, Invoice>();
int iMaxPageNumber = 100;
int iResultsPerPage = 100;
try
{
OAuthConsumerContext consumerContext = new OAuthConsumerContext
{
ConsumerKey = _sConsumerKey,
SignatureMethod = SignatureMethod.HmacSha1,
ConsumerSecret = _sConsumerSecret
};
string sBaseURL = "https://oauth.intuit.com/oauth/v1";
string sUrlRequestToken = "/get_request_token";
string sUrlAccessToken = "/get_access_token";
OAuthSession oSession = new OAuthSession(consumerContext,
sBaseURL + sUrlRequestToken,
sBaseURL,
sBaseURL + sUrlAccessToken);
oSession.AccessToken = new TokenBase
{
Token = _sAccessToken,
ConsumerKey = _sConsumerKey,
TokenSecret = _sAccessTokenSecret
};
int iPageNumber = QUERY_START_PAGE_NUMBER;
string sCustomerId = CustomerId.Value;
string sBodyBase = "PageNum={0}&ResultsPerPage={1}&Filter=OpenBalance :GreaterThan: 0.00 :AND: CustomerId :EQUALS: {2}";
string sBody = String.Format(sBodyBase, iPageNumber, iResultsPerPage, sCustomerId);
IConsumerRequest conReq = oSession.Request();
conReq = conReq.Post().WithRawContentType("application/x-www-form-urlencoded").WithRawContent(System.Text.Encoding.ASCII.GetBytes(sBody)); ;
conReq = conReq.ForUrl(_DataService.ServiceContext.BaseUrl + "invoices/v2/" + _DataService.ServiceContext.RealmId);
conReq = conReq.SignWithToken();
// Complete the Query calls to build the list
SearchResults searchResults = (SearchResults)_DataService.ServiceContext.Serializer.Deserialize<SearchResults>(conReq.ReadBody());
IEnumerable<Invoice> results = ((Invoices)searchResults.CdmCollections).Invoice;
IEnumerable<Invoice> qboInvoices = results;
int iCount = searchResults.Count;
while (iCount > 0 && iCount == iResultsPerPage && iPageNumber <= iMaxPageNumber)
{
iPageNumber++;
sBody = String.Format(sBodyBase, iPageNumber, iResultsPerPage, sCustomerId);
conReq = oSession.Request();
conReq = conReq.Post().WithRawContentType("application/x-www-form-urlencoded").WithRawContent(System.Text.Encoding.ASCII.GetBytes(sBody)); ;
conReq = conReq.ForUrl(_DataService.ServiceContext.BaseUrl + "invoices/v2/" + _DataService.ServiceContext.RealmId);
conReq = conReq.SignWithToken();
searchResults = (SearchResults)_DataService.ServiceContext.Serializer.Deserialize<SearchResults>(conReq.ReadBody());
results = ((Invoices)searchResults.CdmCollections).Invoice;
qboInvoices = qboInvoices.Concat(results);
iCount = searchResults.Count;
}
if (bById)
foreach (Invoice Inv in qboInvoices)
dictionary.Add(Inv.Id.Value, Inv);
else
foreach (Invoice Inv in qboInvoices)
dictionary.Add(Inv.Header.DocNumber, Inv);
return dictionary;
}
catch (Exception)
{
return null;
}
}
* UPDATE *
There is a similar issue out there that involves the new api tester. This could be related to this issue and they are currently looking into it.
Stack Overflow: QuickBooks Online querying with filter returns 401 everytime
回答1:
This is a bug in the DevKit. The OpenBalance filter defaults to :EQUALS: and does not support :GreaterThan:.

Here is a workaround using DevDefined to construct the OAuth header:
public List<Intuit.Ipp.Data.Qbo.Invoice> GetQboUnpaidInvoices(DataServices dataServices, int startPage, int resultsPerPage, IdType CustomerId)
{
StringBuilder requestXML = new StringBuilder();
StringBuilder responseXML = new StringBuilder();
var requestBody = String.Format("PageNum={0}&ResultsPerPage={1}&Filter=OpenBalance :GreaterThan: 0.00 :AND: CustomerId :EQUALS: {2}", startPage, resultsPerPage, CustomerId.Value);
HttpWebRequest httpWebRequest = WebRequest.Create(dataServices.ServiceContext.BaseUrl + "invoices/v2/" + dataServices.ServiceContext.RealmId) as HttpWebRequest;
httpWebRequest.Method = "POST";
httpWebRequest.ContentType = "application/x-www-form-urlencoded";
httpWebRequest.Headers.Add("Authorization", GetDevDefinedOAuthHeader(httpWebRequest, requestBody));
requestXML.Append(requestBody);
UTF8Encoding encoding = new UTF8Encoding();
byte[] content = encoding.GetBytes(requestXML.ToString());
using (var stream = httpWebRequest.GetRequestStream())
{
stream.Write(content, 0, content.Length);
}
HttpWebResponse httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse;
using (Stream data = httpWebResponse.GetResponseStream())
{
Intuit.Ipp.Data.Qbo.SearchResults searchResults = (Intuit.Ipp.Data.Qbo.SearchResults)dataServices.ServiceContext.Serializer.Deserialize<Intuit.Ipp.Data.Qbo.SearchResults>(new StreamReader(data).ReadToEnd());
return ((Intuit.Ipp.Data.Qbo.Invoices)searchResults.CdmCollections).Invoice.ToList();
}
}
protected string GetDevDefinedOAuthHeader(HttpWebRequest webRequest, string requestBody)
{
OAuthConsumerContext consumerContext = new OAuthConsumerContext
{
ConsumerKey = consumerKey,
ConsumerSecret = consumerSecret,
SignatureMethod = SignatureMethod.HmacSha1,
UseHeaderForOAuthParameters = true
};
consumerContext.UseHeaderForOAuthParameters = true;
//URIs not used - we already have Oauth tokens
OAuthSession oSession = new OAuthSession(consumerContext, "https://www.example.com",
"https://www.example.com",
"https://www.example.com");
oSession.AccessToken = new TokenBase
{
Token = accessToken,
ConsumerKey = consumerKey,
TokenSecret = accessTokenSecret
};
IConsumerRequest consumerRequest = oSession.Request();
consumerRequest = ConsumerRequestExtensions.ForMethod(consumerRequest, webRequest.Method);
consumerRequest = ConsumerRequestExtensions.ForUri(consumerRequest, webRequest.RequestUri);
if (webRequest.Headers.Count > 0)
{
ConsumerRequestExtensions.AlterContext(consumerRequest, context => context.Headers = webRequest.Headers);
if (webRequest.Headers[HttpRequestHeader.ContentType] == "application/x-www-form-urlencoded")
{
Dictionary<string, string> formParameters = new Dictionary<string, string>();
foreach (string formParameter in requestBody.Split('&'))
{
formParameters.Add(formParameter.Split('=')[0], formParameter.Split('=')[1]);
}
consumerRequest = consumerRequest.WithFormParameters(formParameters);
}
}
consumerRequest = consumerRequest.SignWithToken();
return consumerRequest.Context.GenerateOAuthParametersForHeader();
}
