A practical guide to designing HTTP APIs that hold up over years of change — naming, versioning, error shapes, pagination, and the small choices that compound.
Read articleHow to think about service boundaries, data ownership, communication patterns, and the failure modes that distributed systems force you to design around.
Read articleToken bucket, leaky bucket, fixed window, sliding window — what each algorithm gets right, what it gets wrong, and how to pick the one that fits the API you're protecting.
Read articleHow idempotency keys make API retries safe — the contract between client and server, where to store the key, how long to keep it, and the corner cases that catch real implementations out.
Read articleDesigning webhooks that survive contact with the real internet — signing, retries, ordering, replay protection, and the failure modes that catch new implementations.
Read articleOffset, cursor, and keyset pagination compared — how each behaves under inserts, the storage they need, and the API shape that exposes them well.
Read articleStatus codes, problem-details envelopes (RFC 7807), partial-success patterns, and what separates an actionable error response from a useless one.
Read articleThe blog focuses on the parts of API work that don't fit cleanly into reference documentation: the design decisions, the trade-offs, the patterns that show up across different stacks, and the failure modes you only learn about by running things in production.
Each article is paired with the relevant pages elsewhere on the site. Articles on REST design link back to the REST reference; pieces on authentication tie into the auth reference and the authentication guide; architecture pieces reference the integration guide.
