What to build
Call the merchant summary report for totals over a period, and the payment type summary when the split by card, ACH, and the rest is what you are reporting. Run it on the cadence your report is published on. Don't build a webhook receiver for this: you would be accumulating a number this platform will hand you in one call.
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
- Ask for a closed period. A total over a window that includes the current hour changes between two runs, which reads as a discrepancy in a report that's behaving correctly.
- Settlement, refunds, and chargebacks move a figure after the payment. Decide which of those your total is supposed to reflect before you compare two runs against each other.
