Overview

Seam provides a universal API to connect and control many brands of smart locks. This guide provides a rapid introduction to connecting and controlling your Schlage lock using the Seam API. Note that this guide is intended for Schlage Sense locks and Schlage Encode locks that connect to wifi. For Z-Wave Schlage locks such as Schlage Connect, head over to our guide for SmartThings. To learn more about other smart lock brands supported by Seam such as August, Yale, and Salto, head over to our integration page.

​
1 — Install Seam SDK

Seam provides client libraries for many languages, such as JavaScript, Python, Ruby, PHP, and others, as well as a Postman collection and OpenAPI spec. 
npm i seam
Once installed, sign-up for Seam to get your API key, and export it as an environment variable: 
$ export SEAM_API_KEY=seam_test2ZTo_0mEYQW2TvNDCxG5Atpj85Ffw
This guide uses a Sandbox Workspace. Only virtual devices can be connected. If you need to connect a real Schlage Lock, use a non-sandbox workspace and API key.
To control your Schlage lock via the Seam API, you must first authorize your Seam workspace against your Schlage account. To do so, Seam provides Connect Webviews: pre-built UX flows that walk you through authorizing your application to control your Schlage lock.

​
Request a Connect Webview

import { Seam } from 'seam'

const seam = new Seam()

const { connect_webview: connectWebview } = await seam.connectWebviews.create({
accepted_providers: ['schlage'],
})

console.log(connectWebview.login_successful) // false

// Send the webview URL to your user
console.log(connectWebview.url)

​
Authorize Your Workspace

Navigate to the URL returned by the Webview object. Since you are using a sandbox workspace, complete the login flow by entering the Schlage sandbox test accounts credentials below: Confirm the Connect Webview was successful by querying its status: 
const updatedWebview = await seam.connectWebviews.get(
  connectWebview.connect_webview_id,
)

console.log(updatedWebview.login_successful) // true

​
3 — Retrieve Schlage Lock Devices

After a Schlage account is linked with Seam, you can retrieve devices for this Schlage account. The Seam API exposes most of the device’s properties such as battery level or door lock status. 
const allLocks = await seam.locks.list()

const someLock = allLocks[0]

console.log(someLock.properties.online) // true
console.log(someLock.properties.locked) // true

console.log(someLock)
/*
{
  device_id: 'e2d95c42-b2bf-4d07-9211-7407d9c90c73',
  device_type: 'schlage_lock',
  capabilities_supported: [ 'access_code', 'lock' ],
  properties: {
    locked: false,
    online: true,
    manufacturer: 'schlage',
    battery_level: 0.48,
    schlage_metadata: {
      device_id: 'device-1',
      device_name: 'FRONT DOOR',
      access_code_length: 4
    },
    name: 'FRONT DOOR'
  },
  location: null,
  connected_account_id: '1de737bc-12d1-4631-8a56-dbb2e61f1f51',
  workspace_id: 'd7418ff3-a476-4f48-9a4b-211d1d21a03d',
  created_at: '2022-12-16T01:15:17.478Z',
  errors: [],
  warnings: []
}
*/

4 — Locking & Unlocking a Door

Next, you can perform the basic action of locking and unlocking the door.
POST /locks/lock_door See the API Reference for details.

​
Unlock a door

POST https://connect.getseam.com/locks/unlock_door

​
Request Body

NameTypeDescription
device_idString
// lock the door
await seam.locks.lockDoor(someLock.device_id)
const updatedLock = await seam.locks.get(someLock.device_id)
console.log(updatedLock.properties.locked) // true

// unlock the door
await seam.locks.unlockDoor(someLock.device_id)
updatedLock = await seam.locks.get(someLock.device_id)
console.log(updatedLock.properties.locked) // false

​
5 — Setting Access Code on Schlage Lock

All Schlage wifi locks come with a keypad built-in to program access codes. These codes can then be entered to unlock a Schlage lock. The Seam API makes it easy to program both ongoing codes and timebound codes on a Schlage lock. You can find out more about Schlage lock access code in our core concept section on access codes. 
// create an ongoing code
await seam.accessCodes.create({
  device_id: someLock.device_id,
  code: '123456',
  name: 'Personal Access Code',
})

// create a timebound code
await seam.accessCodes.create({
  device_id: someLock.device_id,
  code: '888888',
  name: 'My Temp Access Code',
  starts_at: '2028-11-12T19:23:42+0000',
  ends_at: '2028-11-13T19:23:42+0000',
})

// use a device_id as the "device_id" parameter
await seam.accessCodes.list({
  device_id: someLock.device_id,
})

/*
[
  {
    code: '1988',
    type: 'ongoing',
    status: 'setting',
    created_at: '2022-08-26T12:50:17.858Z',
    access_code_id: '26d6138c-6524-4f3c-ac96-43cc3bea0a8d'
  },
  {
    type: 'timebound',
    code: '888888',
    starts_at: '2028-08-12T19:24:00.000Z',
    ends_at: '2028-08-13T19:24:00.000Z',
    access_code_id: '8c2db4da-b137-4c08-a2c3-d611e6ff91b3',
  }
]
*/

Next Steps

Now that you’ve completed this guide, you can try to connect a real Schlage device. To do so, make sure to switch to a non-sandbox workspace and API key as real devices cannot be connected to sandbox workspaces.
