Frequently asked questions

Does an API gateway handle requests from external users?

An API gateway handles north-south traffic – that’s the flow of requests from clients to backend services. It provides essential features like authentication, routing, and rate limiting for external access.

How can I manage different versions of my APIs?

You can manage API versions using URL paths (like /api/v1/), HTTP headers specifying the version, or query parameters. URL versioning is generally preferred due to its clarity and ease of implementation.

What does rate limiting protect against?

Rate limiting protects your APIs from abuse, ensures fair usage by clients, and prevents services from being overwhelmed with requests. It’s a crucial layer for maintaining stability and performance.

What are the different methods for securing API access?

Several methods can secure your APIs, including OAuth 2.0 for user authentication, JWT (JSON Web Tokens) for stateless access control, API keys for simple authorization, and mutual TLS (mTLS) for strong, service-to-service security.
