Seam Python SDK

SDK for the Seam API written in Python.

Description

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.

Installation

This package is registered on the Python Package Index (PyPI) as seam.

Install it with:

$ pip install seam

Usage

Examples

Note: These examples assume `SEAM_API_KEY` is set in your environment.

List devices

from seam import Seam

seam = Seam()
devices = seam.devices.list()

Unlock a door

from seam import Seam

seam = Seam()
lock = seam.locks.get(name="Front Door")
seam.locks.unlock_door(device_id=lock.device_id)

Authentication Method

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.

API Key

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")

Personal Access Token

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",
)

Action Attempts

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 timeout at the polling_interval (both in seconds).
• Resolves with a fresh copy of the successful action attempt.
• Raises a SeamActionAttemptFailedError if the action attempt is unsuccessful.
• Raises a SeamActionAttemptTimeoutError if the action attempt is still pending when the timeout is reached.
• Both errors expose an action_attempt property.

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")

Interacting with Multiple Workspaces

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()

Webhooks

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)

Advanced Usage

Setting the endpoint

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.

Development and Testing

Quickstart

$ 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.

Source Code

The source code is hosted on GitHub. Clone the project with

$ git clone https://github.com/seamapi/python.git

Requirements

You will need Python 3 and Poetry and Node.js with npm.

Install the development dependencies with

$ poetry install
$ npm install

Tests

Lint code with

$ make lint

Run tests with

$ make test

Run tests on changes with

$ make watch

Publishing

New versions are created with poetry version.

Automatic

New versions are released automatically with semantic-release as long as commits follow the Angular Commit Message Conventions.

Manual

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

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.

Secrets for Optional GitHub Actions

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.
