Money moves through a third-party processor's webhooks, which retry and arrive out of order, so you risk double-provisioning and failing to reverse on refund, and auditors need every discrepancy visible. The data is regulated: it can't leave an approved region and secrets can't sit in the build artifact.

How we would approach it

Claim an idempotency ledger keyed on (order, event) atomically before any side effect so a grant can never double-run, revoke on refund by reason code, and when a paid amount doesn't match the expected price still provision but record the discrepancy for reconciliation instead of silently failing a paying customer, plus alert on the silent-failure class where you correctly return 200 to the processor but a downstream step failed and no 5xx exists to catch it. For the data itself: verified TLS with a pinned CA and a startup check that reads the actually-negotiated cipher rather than trusting config, secrets fetched at runtime from a secret manager, and any automated state change gated behind human approval.
