SDK for the Seam API written in Python.
Seam makes it easy to integrate IoT devices with your applications. This is an official SDK for the Seam API. Please refer to the official Seam Docs to get started.
Parts of this SDK are generated from always up-to-date type information provided by @seamapi/types node package. This ensures all API methods, request shapes, and response shapes are accurate and fully typed.
This package is registered on the Python Package Index (PyPI) as seam.
Install it with:
$ pip install seam
Note: These examples assume `SEAM_API_KEY` is set in your environment.
from seam import Seam
seam = Seam()
devices = seam.devices.list()from seam import Seam
seam = Seam()
lock = seam.locks.get(name="Front Door")
seam.locks.unlock_door(device_id=lock.device_id)The SDK supports API key and personal access token authentication mechanisms.
Authentication may be configured by passing the corresponding options directly to the Seam constructor, or with the more ergonomic static factory methods.
An API key is scoped to a single workspace and should only be used on the server. Obtain one from the Seam Console.
# Set the `SEAM_API_KEY` environment variable
seam = Seam()
# Pass as the first argument to the constructor
seam = Seam("your-api-key")
# Pass as a keyword argument to the constructor
seam = Seam(api_key="your-api-key")
# Use the factory method
seam = Seam.from_api_key("your-api-key")A Personal Access Token is scoped to a Seam Console user. Obtain one from the Seam Console. A workspace ID must be provided when using this method and all requests will be scoped to that workspace.
# Pass as an option to the constructor
seam = Seam(
personal_access_token="your-personal-access-token",
workspace_id="your-workspace-id",
)
# Use the factory method
seam = Seam.from_personal_access_token(
"your-personal-access-token",
"your-workspace-id",
)Some asynchronous operations, e.g., unlocking a door, return an action attempt. Seam tracks the progress of the requested operation and updates the action attempt when it succeeds or fails.
To make working with action attempts more convenient for applications,
this library provides the wait_for_action_attempt option and enables it by default.
When the wait_for_action_attempt option is enabled, the SDK:
- Polls the action attempt up to the
timeoutat thepolling_interval(both in seconds). - Resolves with a fresh copy of the successful action attempt.
- Raises a
SeamActionAttemptFailedErrorif the action attempt is unsuccessful. - Raises a
SeamActionAttemptTimeoutErrorif the action attempt is still pending when thetimeoutis reached. - Both errors expose an
action_attemptproperty.
If you already have an action attempt ID and want to wait for it to resolve, simply use
seam.action_attempts.get(action_attempt_id=action_attempt_id)Or, to get the current state of an action attempt by ID without waiting,
seam.action_attempts.get(
action_attempt_id=action_attempt_id,
wait_for_action_attempt=False,
)To disable this behavior, set the default option for the client:
seam = Seam(
api_key="your-api-key",
wait_for_action_attempt=False,
)
seam.locks.unlock_door(device_id=device_id)or the behavior may be configured per-request:
seam.locks.unlock_door(
device_id=device_id,
wait_for_action_attempt=False,
)The polling_interval and timeout may be configured for the client or per-request.
For example:
from seam import Seam, SeamActionAttemptFailedError, SeamActionAttemptTimeoutError
seam = Seam("your-api-key")
lock = seam.locks.list()
if len(locks) == 0:
raise Exception("No locks in this workspace")
lock = locks[0]
try:
seam.locks.unlock_door(
device_id=lock.device_id,
wait_for_action_attempt={
"timeout": 5.0,
"polling_interval": 1.0,
},
)
print("Door unlocked")
except SeamActionAttemptFailedError as e:
print("Could not unlock the door")
except SeamActionAttemptTimeoutError as e:
print("Door took too long to unlock")Some Seam API endpoints interact with multiple workspaces. The SeamMultiWorkspace client is not bound to a specific workspace and may use those endpoints with a personal access token authentication method.
A Personal Access Token is scoped to a Seam Console user. Obtain one from the Seam Console.
# Pass as an option to the constructor
seam = SeamMultiWorkspace(personal_access_token="your-personal-access-token")
# Use the factory method
seam = SeamMultiWorkspace.from_personal_access_token("your-personal-access-token")
# List workspaces authorized for this Personal Access Token
workspaces = seam.workspaces.list()The Seam API implements webhooks using Svix.
This SDK exports a thin wrapper SeamWebhook around the svix package.
Use it to parse and validate Seam webhook events.
Refer to the Svix docs on Consuming Webhooks for an in-depth guide on best-practices for handling webhooks in your application.
This example is for Flask, see the Svix docs for more examples in specific frameworks.
import os
from flask import Flask, request
from seam import SeamWebhook
app = Flask(__name__)
webhook = SeamWebhook(os.getenv('SEAM_WEBHOOK_SECRET'))
@app.route('/webhook', methods=['POST'])
def handle_webhook():
try:
data = webhook.verify(request.get_data(), request.headers)
except Exception:
return 'Bad Request', 400
try:
store_event(data)
except Exception:
return 'Internal Server Error', 500
return '', 204
def store_event(data):
print(data)
if __name__ == '__main__':
app.run(port=8080)Some contexts may need to override the API endpoint, e.g., testing or proxy setups.
Either pass the endpoint option to the constructor, or set the SEAM_ENDPOINT environment variable.
$ git clone https://github.com/seamapi/python.git $ cd pypackage $ poetry install
Run each command below in a separate terminal window:
$ make watch
Primary development tasks are defined in the Makefile.
The source code is hosted on GitHub. Clone the project with
$ git clone https://github.com/seamapi/python.git
You will need Python 3 and Poetry and Node.js with npm.
Install the development dependencies with
$ poetry install $ npm install
Lint code with
$ make lint
Run tests with
$ make test
Run tests on changes with
$ make watch
New versions are created with poetry version.
New versions are released automatically with semantic-release as long as commits follow the Angular Commit Message Conventions.
Publish a new version by triggering a version workflow_dispatch on GitHub Actions.
The version input will be passed as the first argument to poetry version.
This may be done on the web or using the GitHub CLI with
$ gh workflow run version.yml --raw-field version=<version>
GitHub Actions should already be configured: this section is for reference only.
The following repository secrets must be set on GitHub Actions.
PYPI_API_TOKEN: API token for publishing on PyPI.
These must be set manually.
The version, format, generate, and semantic-release GitHub actions require a user with write access to the repository including access to read and write packages. Set these additional secrets to enable the action:
GH_TOKEN: A personal access token for the user.GIT_USER_NAME: The name to set for Git commits.GIT_USER_EMAIL: The email to set for Git commits.GPG_PRIVATE_KEY: The GPG private key.GPG_PASSPHRASE: The GPG key passphrase.
Please submit and comment on bug reports and feature requests.
