3.2.1.4 The GetInvoices/GetInvoicesArchive methods
These methods are omitted. It’s recommended to use the GetInvoiceByID method instead.
These methods allow signed invoices to be downloaded. The yellowbill system considers any bill collected
using GetInvoices as paid from this moment onwards. The payer is then responsible for settling the
amount through the usual payment channels.
DownloadFile[] GetInvoices( String eBillAccountID, DateTime DeliveryDate );
DownloadFile[] GetInvoicesArchive( String eBillAccountID, DateTime DeliveryDate );
Not only the eBillAccountID but also a DeliveryDate is supplied, as already mentioned above. It can be
taken from the response above. Each 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 contents in the form of a binary stream (Data). You now save it into a
file. Any further processing of the invoice is the payer’s responsibility.
3.2.1.5 The GetPDF / GetPDFArchive methods
These methods are omitted. It’s recommended to use the GetInvoiceByID method instead.
These methods enable the invoice details to be downloaded as a PDF file (in print format). The bill
recipient can then archive these details electronically. These methods are used in the same way as those
above.
DownloadFile[] GetPDF( String eBillAccountID, DateTime DeliveryDate );
DownloadFile[] GetPDFArchive( String eBillAccountID, DateTime DeliveryDate
);
