Frequently Asked Questions: Enterprise API
How do you ensure API security?
We implement multiple security layers: OAuth 2.0 and API key authentication, JWT token management, TLS 1.3 encryption for all communications, rate limiting to prevent abuse, IP whitelisting options, and comprehensive audit logging. All APIs undergo security testing and comply with OWASP API Security Top 10. For enterprise clients, we support SAML SSO integration and custom security requirements.
How is API versioning handled?
We use semantic versioning (v1, v2, etc.) with clear versioning strategies in the URL path or headers. Old API versions remain available with guaranteed backward compatibility for at least 12 months. Breaking changes are only introduced in major version updates, with 6-month advance notice, detailed migration guides, and a parallel operation period where both versions run simultaneously.
What documentation do we receive?
You receive comprehensive API documentation including complete OpenAPI/Swagger specifications, interactive API explorer for testing endpoints, code examples in multiple languages (JavaScript, Python, Java, C#), detailed authentication guides, webhook integration documentation, error code reference, and rate limiting guidelines. Plus video tutorials for your development team and a dedicated onboarding session.
How do you handle breaking changes?
Breaking changes follow a strict governance process: 6-month deprecation notice via email and API response headers, detailed migration documentation with code examples, new version released in parallel (no forced upgrades), dedicated support channel during migration period, and automated compatibility testing tools. We ensure zero-downtime transitions with gradual rollout strategies.
What about monitoring and observability?
Every API includes enterprise-grade monitoring: real-time performance metrics (latency, throughput, error rates), distributed tracing for request flows, custom dashboards with business-relevant KPIs, automated alerting for anomalies, detailed logging with correlation IDs, and API health checks. You get access to Grafana/Datadog dashboards and can integrate with your existing monitoring stack via webhooks or API.
How is the API tested before go-live?
We follow a comprehensive testing strategy: unit tests for all endpoints (90%+ coverage), integration tests with dependent systems, load testing to verify performance under expected traffic (and 3x peak load), security penetration testing, contract testing to ensure compatibility, and chaos engineering to test resilience. You receive a dedicated staging environment that mirrors production for your own testing, plus a sandbox with mock data for parallel development.
