When a customer has paid and the transaction has been closed, POS sends a request to finish the transaction with Liquid Barcodes.
Confirm the transaction
POS uses the finalizing request POST /applicator/sale/{SaleId}/finalization to confirm the transaction.
Cancel transaction
If a customer wants to add products or on unsuccessful payment, POS sends a cancel request to Liquid Barcodes, also using POST /applicator/sale/{SaleId}/finalization and Cancel = TRUE.
