"I'm integrating card-present transactions using a MagTek DynaFlex II SCR (SRED/DUKPT encrypted). I want to send the encrypted payload via createTransactionRequest using opaqueData. Can someone confirm: (1) what dataDescriptor value to use for MagTek DUKPT-encrypted data, (2) whether the encrypted track data from MagneSafe goes in dataValue as-is or needs reformatting, and (3) whether sandbox accepts test encrypted payloads or only works with live reader output? I have a sandbox account and the MagTek SDK."
Thanks in advance for any help.
