REST APIs Development

Versioned, documented APIs with predictable error contracts.

Most APIs are not hard to build and are very hard to live with. The difficulty is not the endpoints; it is everything around them — what happens when a field is added, how a client tells a validation failure from an outage, whether an integration written last year still works today. A REST API is a contract with people you will never meet. We design them that way: resources modelled around the domain rather than the database tables, versioning decided before the first consumer exists, and errors that carry a machine-readable code alongside the human sentence.

Why we use it

REST remains our default for integration work, because it is universally understood, cacheable, debuggable with tools every developer already has, and readable in a log without special tooling. When a partner's team has to integrate in a week, that familiarity is worth more than elegance. We move to GraphQL when clients genuinely need to shape their own queries, and to gRPC for internal service-to-service traffic where payload size and latency dominate. For a public API consumed by third parties, REST is almost always the right answer.
