Quickstart

Request a remote unlock

Set SEAM_API_KEY and replace the example device ID with a connected Latch device that supports this operation. Check can_remotely_unlock before sending the request. Inspect the action attempt and result.was_confirmed_by_device; success alone does not prove physical-device confirmation or that a door opened.

1// Set SEAM_API_KEY on your server.
2import { Seam } from "seam"
3
4const seam = new Seam()
5
6// Replace with a connected lock's device_id.
7const device = await seam.devices.get({ device_id: "6ba7b811-9dad-11d1-80b4-00c04fd430c8" })
8if (device.can_remotely_unlock !== true) {
9  throw new Error("This lock cannot remotely unlock right now")
10}
11const action = await seam.locks.unlockDoor({ device_id: device.device_id })
12console.log(action) // Check status and result.was_confirmed_by_device.

Fastest path

Build it with your AI agent

Install the Seam plugin and your coding agent picks up three integration skills: Reservation Automations, Access Grants and Access Codes. It then writes the calls the way we would. Paste the prompt below and let it build.

1. Install the plugin

/plugin marketplace add seamapi/seam-plugin
/plugin install seam@seamapi

The Claude Code install also adds our documentation MCP server, so the agent can look up endpoints and device capabilities while it works. Cursor, Codex and other agents get the skills through npx skills add and can add the MCP server there separately.

2. Paste this prompt

Prompt

Using the Seam docs, integrate Latch devices into my app. Confirm the model and system are supported, check whether a sandbox simulation is available, connect a device, confirm can_remotely_unlock is true, and call /locks/unlock_door. Inspect the action attempt and result.was_confirmed_by_device, and read the reported lock state. Explain why this does not prove that the door opened. Then show me how to listen for lock.unlocked events on a webhook.

FAQ

Frequently asked questions

Which Latch devices work with Seam?

The catalog lists 5 Latch models, of which 5 have Live or Beta support. Accessories are excluded from these model counts. Browse the manufacturer catalog for specific models, supported systems and requirements. Catalog inclusion alone does not mean Seam supports a device.

How do I connect Latch devices to my app?

Choose a supported model and connected system in the catalog, then follow its setup guide. Connection steps depend on the system and may use Seam Connect Webview or require additional configuration. Read the connected device's capability flags before offering an action.

Which credentials can Seam issue on Latch devices?

The catalog reports support for mobile keys on qualifying models. Use Access Grants for supported access methods, and check the specific model, connected system and runtime capability flags. Issuance and removal behavior depend on the credential type.

Do I need a Latch account or additional hardware?

Account, permission and hardware requirements depend on the model and the system it connects through. Review the model's catalog entry and the maintained integration guide before choosing hardware or starting the connection flow.

How do I test without hardware?

Use a Seam sandbox workspace with one of its available simulated integrations. Simulator coverage varies by provider and model; confirm availability before planning a hardware-free test, then validate your workflow on the physical system before deployment.
