Simplify-Generated Messages

On this page:

Simplify-generated response messages are sent to the POS in API 1010 for transactions processed offline. This will occur if a transaction is declined locally (no host message) or if the host is unavailable. These messages begin with *SLR (for Simplify Local Response). A Simplify-generated response message will also be sent if a transaction is declined due to a MAC error.


If On-Device SAF is enabled, a different set of Simplify-generated messages will be used for offline situations. See Simplify-Generated Messages for On-Device SAF.

For EMV, Simplify will also generate a response message if the chip declines a host-approved transaction or the customer removes the card before the transaction is completed. These messages begin with *ICC (referring to the chip card).
