A timeout means unknown, not failed

Keep confirming

Context

Checkout’s authored 10-second deadline can expire before the processor outcome is known. Starting another payment would risk charging twice if the unanswered operation succeeded.

Options

  • Keep confirming

    Retain the same logical payment and key while seeking its existing outcome. Identical retries inside the fictional 24-hour window refer to that operation.

  • Start another payment immediately

    Treat a missing answer as failure and create another payment with a new operation key. The first payment may already have succeeded. A new operation permits a possible duplicate charge.
