GET – Retrieve Data

Safe and idempotent reads that never modify server state. Ideal for listings, single‑record fetches, and health checks.

POST – Create Resources

Non‑idempotent operation for adding new records, handling validation, and returning 201 with a Location header.

PUT / PATCH – Update Resources

PUT fully replaces a resource (idempotent) while PATCH applies partial updates. Both benefit from ETag‑based concurrency control.

Your API Can Use the Right HTTP Verb and Still Be Wrong

GET, POST, PUT, PATCH, and DELETE only work well when resource design, status codes, validation, idempotency, caching, concurrency, versioning, and observability are consistent. Moltech Solutions helps turn basic CRUD endpoints into secure, predictable APIs that clients can trust and teams can maintain as traffic and integrations grow.

Scale APIs With Confidence
Are Small API Design Mistakes Creating Bigger Integration Problems?

Moltech Solutions can review routes, HTTP semantics, validation, status codes, caching, idempotency, ETags, versioning, OpenAPI, security, and observability. Get a practical Node.js API improvement plan that reduces client confusion, duplicate writes, update conflicts, and maintenance risk.
