Get Started with Nuki Locks

Learn how to connect and control your Nuki locks with the Seam API.


Seam provides a universal API to connect and control many brands of locks, including Nuki. This guide provides a rapid introduction to connecting and controlling your Nuki locks using the Seam API. To learn more about other device brands supported by the Seam API, such as Yale, Schlage, and August, 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 Nuki device, use a non-sandbox workspace and API key.

To control your Nuki locks via the Seam API, you must first authorize your Seam workspace against your Nuki KS account. To do so, Seam provides Connect Webviews: pre-built UX flows that walk you through authorizing your application to control your Nuki sites.

Request a Connect Webview

// Use Seam SDK to create a connect webview with the provider nuki
const createdConnectWebview = await seam.connectWebviews.create({
  accepted_providers: ["nuki"]

// Print the created webview 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 Nuki sandbox test accounts credentials below:

  • email:

  • password: 1234

Confirm the Connect Webview was successful by querying its status:

updated_webview = seam.connect_webviews.get(webview.connect_webview_id)

assert updated_webview.login_successful # true

3 — Retrieve Nuki Devices

After a Nuki account is linked with Seam, you can retrieve devices for this Nuki account. The Seam API exposes most of the device's properties such as battery level.

all_locks = seam.locks.list()

some_lock = all_locks[0]

assert["online"] is True
assert["battery_level"] is True

# Device(device_id='60d0f1b6-26ae-4366-8d1b-d20ad0d6a62e', device_type='nuki_lock', location=None, properties={'locked': False, 'online': True, 'manufacturer': 'nuki', 'battery_level': 0.86, 'nuki_metadata': {'device_id': '545636388', 'device_name': 'Office Lock'}, 'max_active_codes_supported': 100, 'supported_code_lengths': [6], 'name': 'Office Lock'}, capabilities_supported=['access_code', 'lock'], errors=[])

4 — Locking & Unlocking a Door

Next, you can perform the basic action of locking and unlocking a door.

Unlock a door


Request Body




# lock the door
updated_lock = seam.locks.get(some_lock.device_id)
assert["locked"] is True

# Now unlock the door
updated_lock = seam.locks.get(some_lock.device_id)
assert["locked"] is False

5 — Setting Access Code on Nuki Lock

Some Nuki locks also have a keypad paired to them to program access codes. These codes can then be entered to unlock a Nuki lock.

The Seam API makes it easy to program both ongoing codes and timebound codes on a Nuki lock. You can find out more about Nuki lock access code in our core concept section on access codes.

Nuki does not let you create a code starting with the digits "12". Codes cannot contain the digit 0.

# create an ongoing code
  name="Personal Access Code")

# create a timebound code
  name="My Temp Access Code",

# you can use a device or a device_id as the "device" parameter

Next Steps

Now that you've completed this guide, you can try to connect a real Nuki 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.
