What to build
Run the partial approval blueprint, and decide what your checkout does with the shortfall: collect the rest on another payment method, or cancel the partial approval and ask for a different card.
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
- A partial approval that nobody acknowledges is voided automatically. Treat it as a state your checkout has to resolve, not as an approval.
