Boring software, on purpose
Every write endpoint takes an idempotency key. Retry a payment safely after a timeout. Endpoints are versioned, so a new field never breaks your build. We hold a 99.9%+ uptime target on the payment path.
Webhooks are signed and replayable. Decline reasons come back raw from the issuer. Payment and shopper data stays in the EU. The team's background is EU payments rules, scheme requirements and merchant operations. That shows up in the defaults we ship, not in a slide deck.
