Quickstart

Unlock a door in 60 seconds

One call to /locks/unlock_door works on every Latch model with can_remotely_unlock. The action attempt in the response reports when the command lands.
1curl -X POST 'https://connect.getseam.com/locks/unlock_door' \
2  -H "Authorization: Bearer ${SEAM_API_KEY}" \
3  -H 'Content-Type: application/json' \
4  -d '{ "device_id": "6ba7b811-9dad-11d1-80b4-00c04fd430c8" }'

6# The response is an action attempt. Poll /action_attempts/get with its id
7# until status is success, or subscribe to lock.unlocked on a webhook.
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. In a sandbox workspace: connect a virtual Latch device, confirm can_remotely_unlock is true on it, call /locks/unlock_door, wait for the action attempt to succeed, and read properties.locked to prove the state changed. Then show me how to listen for lock.unlocked events on a webhook.

FAQ

Frequently asked questions

Which Latch devices work with Seam?

6 Latch models are in Seam's device database today, covering smartlocks and intercoms. The catalog page lists every model with its live integration status and any hardware requirements.

How do I connect Latch devices to my app?

Your user links their Latch account through Seam Connect Webview: one embedded login flow, no Latch-specific code. Every device behind the account comes back with capability flags your app can read before offering an action.

Which credentials can Seam issue on Latch devices?

mobile keys today, through one /access_grants/create call. Support is per model, so check the capability flags on the specific device before offering a credential in your UI.

Do I need a Latch developer account or API keys?

No. Your user signs in with their own Latch account through the Connect Webview, and your app talks only to Seam. You never handle Latch credentials or maintain their API.

How do I test without hardware?

Sandbox workspaces come with virtual Latch devices that behave like the real ones, so you can run the whole flow before anything is installed.
