Signature Transactions

As part of Spice integration the POS needs to support signature transactions. These transaction involve a response that is sent back to the POS which includes the merchant receipt with cardholder signature line. The POS is then responsible for printing the receipt and the cardholder needs to sign. The merchant will then select if the signature is Accepted or Declined on Spice pop-up and the transaction is finalised.

This workflow requires a slight change in the messaging from a POS perspective. Once the POS receives the merchant receipt for printing it needs to complete a HTTP GET. This GET request will return the outcome of the transaction once the merchant has selected Accept or Decline.
