API Reference

Auth

post
https://testpayarcconnectapi.payarc.net/v3/transactions/postauth

This API endpoint finalizes a pre-authorization command to a terminal. The final approval/decline result is delivered asynchronously to the callbackURL. Terminal connectivity gate: the request returns immediately; before dispatching, the endpoint verifies the terminal is connected to Payarc Connect and, if it is not, responds immediately with 409 TERMINAL_OFFLINE without sending any command to the terminal.
