API design для игровых платформ

Grand API — foundation для всей платформы. Bad API design — technical debt на годы.

Principles

RESTful: resources, HTTP verbs. Consistent: naming, pagination, errors. Versioning: /v1/, /v2/ для evolution. Documentation: OpenAPI spec. Idempotency: safe retries. Rate limiting: fair use enforcement. Backward compatibility: no breaking changes без deprecation period.

Common patterns

Cursor pagination для больших lists. Sparse fieldsets: return только требуемое. Filtering, sorting standardized. Bulk operations: batch endpoints. HATEOAS: discovery через links. ETag для caching.

Security

OAuth2 + PKCE. mTLS для internal APIs. Rate limiting по multiple dimensions. Input validation. Output encoding. CORS правильно настроен. HTTPS everywhere. API keys audit trail.

Gaming-specific

Game aggregators: standard API (ONE Game aPI, SFT Games API). Payment providers: PSP APIs. KYC integrations: Onfido, Sumsub. Regulator reporting: automated feeds. Idempotency обязательно для payment operations.
