Batch Transaction Processing

Batch processing involves a group of transactions submitted in a single file. In the case of a cnpAPI Batch, the parent or root element is the <cnpRequest> element. A single <cnpRequest>, referred to as a Session, can contain many batches and each batch can contain multiple transactions. We recommend that you use Batch processing for all transaction types except Authorizations and Voids (Online only).

Some of the advantages of using Batch processing are:

• Better Performance - We optimize batch processing by processing multiple transactions in the batch simultaneously. This allows you to process thousands of transactions quickly without writing complicated logic or managing complicated processes.

• Easier Reconciliation - When processing a batch, all transactions within that batch post on the same day. In the case of Online transactions, you could submit two transactions at the same time and one could post today and the other tomorrow. This can cause confusion in your accounting process.

• Easier Error Recovery - A batch processes as a single unit, thus if you experience any system or communication issue while processing a batch, you can easily determine if the file was processed. With Online transactions, determining which individual transactions were not processed can be more difficult.
