Get Started with Nuki Locks

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

Nuki Locks

Overview

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.

• JavaScript / TypeScript (npm, GitHub)

• Python (pip, GitHub)

• Ruby Gem (rubygem, GitHub)

• PHP (packagist, GitHub)

• Java (GitHub)

• C# (nuget, GitHub)

• Go (GitHub)

JavaScript

npm i seam

Python

pip install seam
# For some development environments, use pip3 in this command instead of pip.

Ruby

bundle add seam

PHP

composer require seamapi/seam

Java

Gradle:

// build.gradle
dependencies {
    implementation 'io.github.seamapi:java:0.x.x'
}

Maven:

<!-- pom.xml -->
<dependency>
    <groupId>io.github.seamapi</groupId>
    <artifactId>java</artifactId>
    <version>0.x.x</version>
</dependency>

C#

Install using nuget.

Go

go get github.com/seamapi/go

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.

2 — Link Your Nuki Account with Seam

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

Javascript

// 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
console.log(createdConnectWebview.url);

Python

# Create a webview with Nuki as the provider
created_webview = seam.connect_webviews.create(accepted_providers=["nuki"])

# Assert that login is not yet successful
assert created_webview.login_successful is False

# Print the URL of the webview
print(created_webview.url)

Ruby

# Create a connect webview with the provider "nuki"
created_webview = seam.connect_webviews.create(accepted_providers: ["nuki"])

# The webview will not be logged in, which can be confirmed
raise 'Login should not be succesful' unless !created_webview.login_successful

# Retrieve and print out the url of the webview
puts created_webview.url

PHP

<?php
// initiate the SDK client, you should replace this with your SDK client init portion
$seam = new SeamSeamClient("YOUR_API_KEY");

// create a connect webview with provider nuki
$connect_webview = $seam->connect_webviews->create([
  'accepted_providers' => ['nuki']
]);

// check if the login was successful
assert($connect_webview->login_successful === false);

// print the connect webview URL
print($connect_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: [e-mail]

• password: 1234

Seam Connect Webview flow to connect Nuki account with Seam

Confirm the Connect Webview was successful by querying its status:

Python

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

assert updated_webview.login_successful # true

Javascript

const updatedWebview = await seam.connectWebviews.get(
  connectWebview.connect_webview_id
)

console.log(updatedWebview.login_successful) // true

Ruby

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

puts updated_webview.login_successful # true

PHP

$webview = $seam->connect_webviews->get($webview->id);
echo json_encode($webview);

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.

Python

all_locks = seam.locks.list()

some_lock = all_locks[0]

assert some_lock.properties["online"] is True
assert some_lock.properties["battery_level"] is True

print(some_lock)
# 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=[])

Javascript

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: '60d0f1b6-26ae-4366-8d1b-d20ad0d6a62e',
  device_type: 'nuki_lock',
  capabilities_supported: [ 'access_code', 'lock' ],
  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'
  },
  location: null,
  connected_account_id: '32e92b46-7978-4d48-a3e7-9b04662151b3',
  workspace_id: 'd7418ff3-a476-4f48-9a4b-211d1d21a03d',
  created_at: '2023-02-11T00:46:12.940Z',
  errors: [],
  warnings: []
}
*/

Ruby

some_lock = seam.locks.list.first

puts some_lock.properties.online # true
puts some_lock.properties.locked # true

puts some_lock

# <Seam::Device:0x00730
#   device_id="60d0f1b6-26ae-4366-8d1b-d20ad0d6a62e"
#   device_type="nuki_lock"
#   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"}
#   created_at=2023-02-11 00:46:12.94 UTC
#   errors=[]
#   warnings=[]>

PHP

use Seam\SeamClient;

$seam = new SeamClient('YOUR_API_KEY');

$locks = $seam->locks->list();

echo json_encode($locks);
/*
[{"device_id":"60d0f1b6-26ae-4366-8d1b-d20ad0d6a62e","workspace_id":"d7418ff3-a476-4f48-9a4b-211d1d21a03d","connected_account_id":"32e92b46-7978-4d48-a3e7-9b04662151b3","device_type":"nuki_lock","properties":{"online":true,"locked":false,"door_open":null,"battery_level":0.86,"name":"Office Lock","manufacturer":"nuki","august_metadata":null,"schlage_metadata":null,"smartthings_metadata":null},"location":null,"created_at":"2023-02-11T00:46:12.940Z","capabilities_supported":["access_code","lock"],"errors":[]}]
*/

    headers: {
      "Content-Type": "application/json"
    },
    body: JSON.stringify({}),
});
const data = await response.json();

Unlock a door

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

Request Body

Name	Type	Description
device_id	String

Python

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

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

Javascript

// 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

# lock the door
seam.locks.lock_door(device_id: some_lock.device_id)
updated_lock = seam.locks.get(device_id: some_lock.device_id)
puts updated_lock.properties.locked # true

# unlock the door
seam.locks.unlock_door(device_id: some_lock.device_id)
updated_lock = seam.locks.get(device_id: some_lock.device_id)
puts updated_lock.properties.locked # false

PHP

use Seam\SeamClient;

$seam = new SeamClient('YOUR_API_KEY');

$some_lock = $seam->locks->list()[0];

# unlock the door
$seam->locks->unlock_door($lock->device_id);
# lock the door
$seam->locks->lock_door($lock->device_id);

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.

Python

# create an ongoing code
seam.access_codes.create(
  device=some_lock,
  code="492332",
  name="Personal Access Code")

# create a timebound code
seam.access_codes.create(
  device=some_lock,
  code="498882",
  name="My Temp Access Code",
  starts_at="2028-08-12T19:23:42+0000",
  ends_at="2028-08-13T19:23:42+0000")

# you can use a device or a device_id as the "device" parameter
seam.access_codes.list(device=some_lock)

Javascript

// 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,
})

Ruby

# create an ongoing code
seam.access_codes.create(
  device_id: some_lock.device_id, code: '123456', name: 'Personal Access Code'
)

# create a timebound code
seam.access_codes.create(
  device_id: some_lock.device_id,
  code: '888888',
  name: 'My Temp Access Code',
  starts_at: '2028-08-12T19:23:42+0000',
  ends_at: '2028-08-13T19:23:42+0000'
)

seam.access_codes.list(device_id: some_lock.device_id)

PHP

use Seam\SeamClient;

$seam = new SeamClient("YOUR_API_KEY");

$some_lock = $seam->locks->list()[0];
$seam->access_codes->create(
  device_id: $some_lock->device_id, code: '123456', name: 'Personal Access Code'
);

$seam->access_codes->create(
  device_id: $some_lock->device_id,
  name: 'My Temp Access Code',
  code: '888888',
  starts_at: '2028-08-12T19:23:42+0000',
  ends_at: '2028-08-13T19:23:42+0000'
);

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.
