Seam × 2N

Seam connects 29 2N models to your app: intercoms and smartlocks. Grant access, control devices and read state through one API, with capability flags that tell your app what each model can do.

Quickstart

Create an access code in 60 seconds

One Access Grant issues the code on a connected 2N lock. Seam generates the PIN, programs the device, and removes it when the window closes.

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 Access Grants skill, integrate 2N devices into my app. In a sandbox workspace: connect a virtual 2N device, read its capability flags, create an access grant with requested_access_methods [{ mode: "code" }] for a three-day window, then read the code back once is_issued is true. Explain what Seam did on the device at each step.

FAQ

Frequently asked questions

Which 2N devices work with Seam?

29 2N models are in Seam's device database today, covering intercoms and smartlocks. The catalog page lists every model with its live integration status and any hardware requirements.

How do I connect 2N devices to my app?

Your user links their 2N account through Seam Connect Webview: one embedded login flow, no 2N-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 2N devices?

online access codes 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 2N developer account or API keys?

No. Your user signs in with their own 2N account through the Connect Webview, and your app talks only to Seam. You never handle 2N credentials or maintain their API.

How do I test without hardware?

Sandbox workspaces come with virtual 2N devices that behave like the real ones, so you can run the whole flow before anything is installed.
