Frequently Asked Questions

What is the best API management tool for small development teams?

Postman is the best API management tool for small development teams due to its free plan that supports individual developers with API testing, documentation, and collaboration features. For teams needing a lightweight API gateway, Kong open-source version or AWS API Gateway with pay-as-you-go pricing provide cost-effective options. RapidAPI free plan is ideal for teams that primarily consume third-party APIs rather than publish their own. The right choice depends on whether your team primarily develops APIs, consumes APIs, or needs gateway infrastructure for production traffic.

What is the difference between an API gateway and an API management platform?

An API gateway is a runtime component that sits between API consumers and backend services, handling cross-cutting concerns like authentication, rate limiting, traffic routing, and request transformation. An API management platform encompasses the full API lifecycle including design, testing, documentation, gateway, analytics, developer portal, and monetization. API gateways like Kong and AWS API Gateway focus on runtime performance, while comprehensive platforms like Apigee and MuleSoft provide end-to-end lifecycle management. Many organizations start with a gateway and add management capabilities as their API program matures. Tools like Postman cover the development side without providing a runtime gateway.

How do API management platforms handle API security?

API management platforms handle security through multiple layers including authentication via API keys, OAuth 2.0, JWT tokens, and mutual TLS, authorization through role-based access control and scope-based permissions, rate limiting and throttling to prevent abuse and DDoS attacks, request validation against OpenAPI schemas to reject malformed requests, IP filtering and geoblocking, bot detection and threat protection against common attack vectors, and encryption of data in transit via TLS. Enterprise platforms like Apigee add advanced capabilities including anomaly detection, sensitive data filtering, and compliance with standards like PCI DSS and HIPAA. Security configuration should be applied at the gateway layer rather than in individual backend services to ensure consistent enforcement across all APIs.
