What to build
Run the processor failover blueprint. It gives the sandbox merchant a second processor profile, makes the first refuse to process, and runs both outcomes. The exhausted case is the one to write code for.
What this means for PCI
This is guidance rather than a compliance determination. Which questionnaire you are eligible for depends on your full environment, so confirm it with your QSA or your acquirer before you rely on it.
Worth knowing
- Only a processor answering that it didn't process the payment triggers failover, and it happens once. A decline, a timeout, or a transport failure is final, because it's ambiguous about whether money moved.
