A batch payment is a transaction submitted as part of a payment batch. Payment batches allow the submission of large volumes of transactions in a single file. This file will have a specific format which is referred to as the batch schema, and can be submitted manually via BackOffice or via API. Transactions submitted as part of a payment batch are submitted to the bank link as recurring payments (not to be confused with a recurring payment schedule in BackOffice). This means that the CVV and expiry are not submitted to the bank.
A single payment is a transaction submitted via BackOffice, API, or Internet Portal (Hosted Payment Page, Integrated Payment Page, Custom Checkout). Single payments are submitted to the bank link with the expiry date and if specified the CVV.
