Company builds invoices using its sodftware program and currently the user selects each invoice with credit card and sends request for that invoice to Authorize.net for processing. Currently using AUTH_CAPTURE for the individual transaction. Since the volume of invoices with credit card payments has increased, the company wants to send all the invoices at once to Authorize.net for processing. Does Authorize.net support a batch of invoices in a single transaction? If yes, where should I find the sample code.
