Simulate PIN-debit authorization
Use this endpoint to simulate PIN-debit authorization transactions. The typical use case for dual-message PIN-debit transactions is automated fuel dispenser transactions. The pump sends an initial authorization message to the card issuer. When fueling completes, a clearing message is sent with the final amount. You can view the full request body structure on the Simulations 2.0 — Card Transactions page.
