Seam × KEYINCODE

Seam connects 13 KEYINCODE smartlock models to your app. 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 KEYINCODE lock. Seam generates the PIN, programs the device, and removes it when the window closes.

1# A three-day window starting now, so a copied snippet is never a dead grant.

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 KEYINCODE devices into my app. In a sandbox workspace: connect a virtual KEYINCODE 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 KEYINCODE devices work with Seam?

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

How do I connect KEYINCODE devices to my app?

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

online access codes, mobile keys and encoded plastic cards 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 KEYINCODE developer account or API keys?

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

How do I test without hardware?

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