# Building a Seam-Compatible Smart Lock API

This guide outlines the technical expectations for building a smart-lock API that integrates cleanly with Seam. It covers authentication, API behavior, events, device reporting, and lock-specific features. Use this as a reference when designing or updating your API.

A Seam-compatible API delivers consistent, real-time device behavior through a predictable and modern integration surface. The following pages break down how to design each part of your API so Seam can integrate your smart locks reliably at scale.
