C SDK Simulator

Suggest Edits

The Nayax Marshall SDK includes a simulator to help developers test and debug their device integration with the Nayax payment system. The simulator replicates the behaviour of the actual hardware and software interactions, allowing you to validate the vending process without needing physical hardware.

Simulator

When the C SDK simulator is started on a terminal, its menu will look like this:

[0]: start session 0
[1]: close session 0
[2]: start session 1
[3]: close session 1
[4]: info session
[5]: cancel session
[6]: query sessions
[7]: reader state
[8]: link stats
[9]: quit

The table below describes each option on the simulator terminal.

CommandDescription
Start session 0Starts a session (a transaction).
Close Session 0Only relevant in multisession. Closes the session at the end of a transaction.
