    The Architecture of Professional REST APIs

    HTTP Contracts & Status Codes: The podcast will cover why returning a 200 OK for an error is a massive anti-pattern. Jenny explains the exact contract of 2xx, 4xx, and 5xx status codes, and emphasizes the use of trace IDs and machine-readable error envelopes so clients know exactly what went wrong and how to fix it. Versioning & Pagination: They will discuss the trade-offs of URI, Header, and Query Parameter versioning, with Jenny recommending URI versioning (/v1/users) for public APIs. For pagination, the episode will strongly contrast Offset Pagination (which can skip records or show duplicates during mutations) with Cursor-Based Pagination (which uses an opaque token for stable, high-performance data fetching). Idempotency & Safe Operations: You will learn how to design systems for network failures. The hosts clarify the difference between a safe operation (like GET) and an idempotent one (like PUT or DELETE), and how to implement client-supplied Idempotency-Key headers for POST requests so you never accidentally double-charge a user. Performance Levers: Jenny walks through using Cache-Control and ETag headers for conditional requests, sparse fieldsets to save bandwidth, and standardizing rate limits using algorithms like the Token Bucket or Leaky Bucket. Expert Territory (HATEOAS & Governance): To close out, they will discuss the Richardson Maturity Model, defining Level 3 (HATEOAS) where the server dictates the next possible actions via hypermedia links. The episode ends with the philosophy that API documentation (via OpenAPI) and contract testing are first-class engineering concerns, because breaking an API is a "social contract violation".
