Partner API platform для банка

Зачем банку partner API platform

Telecom хочет issue cards. Маркетплейс хочет split payments. Госпортал хочет verify accounts. Каждый partner integration без platform layer — отдельный snowflake.

Partner API platform consolidates: единая точка входа, predictable contracts, scalable onboarding partners.

Структурные компоненты

API Gateway. Auth (OAuth, mTLS), rate limiting, monitoring.

Developer Portal. Documentation, sandbox, code samples, status pages.

API catalog по доменам: Accounts, Payments, Cards, Lending, KYC, FX.

Contracts and SLAs. Per partner tier. Differentiated.

Monetization layer. Per-call billing, subscription, revenue share.

Security. Beyond auth: scopes, data masking, consent enforcement, audit.

Onboarding flow. Self-service registration, contract acceptance, sandbox access.

Banking-specific concerns

Regulatory licensing. BaaS требует regulatory framework — partner может или не может consume specific APIs.

PCI compliance. Card APIs — strict scope requirements.

PII в response — minimization principle, never expose more, чем partner needs.

Rate limiting strict — partner abuse может cascade в core systems.

Sandbox isolated от production — никаких real customer data.

Где обычно ломается

API design legacy-driven. Endpoints возвращают raw АБС data в 1990s format. Partners не могут consume.

Versioning отсутствует. Change breaks partners synchronously.

Monetization добавлена позже — partners упсет.

Sandbox = production confusion — testing on real customers.

Compliance не верified per partner — regulator audit fails.

Operating model

Owner — Head of Open Banking / Head of Platform.

Teams: API product, API engineering, developer relations, partner success.

Routine — quarterly partner advisory board.
