Methods for Authenticating Devices on a Network

This article introduces API testing fundamentals, emphasizing functional testing (status codes, payload integrity), performance testing (throughput, latency, load/stress considerations and avoiding production), and security testing (separating authentication from authorization, guarding against BOLA, injection, and enforcing rate limits). It provides practical examples and tooling tips (e.g., Postman, Fiddler), highlighting that combining these approaches is essential to build reliable and secure APIs.
