Strengths and weaknesses
- +Single unified API and integration across online, in-app, and in-store (POS) with consistent shopper recognition
- +Interchange++ transparent pricing rather than blended rates, clear visibility into interchange, scheme fees, and markup
- +Strong developer experience: OpenAPI specs, interactive API Explorer, generated SDKs, sandbox with test cards, short release cycles
- –Pricing and minimum monthly invoice make it expensive/opaque for small and low-volume merchants
- –Aggressive automated risk/fraud blocks with no clear appeal process, and reports of frozen or held funds
- –Email-only support with no phone line; slow IT/support responsiveness is a recurring complaint
- +Best-in-class developer experience: clean versioned REST API, idempotency keys, webhooks, and full-parity test/sandbox mode
- +Documentation is an industry gold standard, interactive API reference with per-language snippets
- +First-party SDKs for every major server language plus mobile/JS clients, minimizing boilerplate
- –Flat 2.9% + 30¢ rate is expensive for low-ticket and high-volume merchants vs. negotiated interchange-plus
- –Costs stack quickly: +1.5% international cards, +1% currency conversion, $15 disputes, plus add-on product fees (Billing 0.7%, Tax 0.5%)
- –Risk engine can freeze funds or terminate accounts abruptly with opaque explanations
