3.2.1.2 GetInvoiceByID
This method allows to download a single signed invoice or a PDF billdetail by its TransactionID. It replaces
the omitted method GetInvoces, GetInvoicesArchive, GetPDF and GetPDFArchive. For obtaining the
BilerID and TransactionID, the GetInvoiceListWithID method has to be called first.
DownloadFile GetInvoiceByID( string eBillAccountID, string BillerID, string
TransactionID, string FileType );
The eBillAccountID, BillerID, TransactionID and FileType are expected as parameters to be passed.
The downloaded file is returned in a structure of the type DownloadFile.
public class DownloadFile
{
public byte[] Data;
public String Filename;
}
It contains the Filename and the content in the form of a binary stream (Data). Now you can save it into
a file. Any further processing of the invoice is the responsibility of the payer.
3.2.1.3 The GetOpenList / GetArchiveList methods (omitted)
These methods are omitted. It’s recommended to use the GetInvoiceWithIDs method instead.
Both methods return a list of available downloads with the most important details. The interfaces are as
follows:
Report[] GetOpenList( String eBillAccountID );
Report[] GetArchiveList( String eBillAccountID );
They expect the eBillAccountID parameter (unique identifier of payer) to be passed. The result is returned
in the form of an array of type Report with the following structure.
public class Report
{
public DateTime DeliveryDate;
public String FileType;
public int Count;
}
This type of report entry corresponds to a daily report for each file type. The DeliveryDate is the invoice
date supplied by the biller when uploading it. The FileType may be "PDF", "RGXMLSIG" or "EDIFACT".
Count contains the number of downloadable files with the same DeliveryDate. This information may be
used for the download methods.
