SDK for the Seam API written in Python.

Description

Seam <seam_home_>_ 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 <https://docs.seam.co/latest/>_ to get started.

Parts of this SDK are generated from always up-to-date type information provided by @seamapi/types <https://github.com/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

.. _seam: https://pypi.python.org/pypi/seam .. _Python Package Index (PyPI): https://pypi.python.org/

Usage

Examples

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

List devices
^^^^^^^^^^^^

.. code-block:: python

  from seam import Seam

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

Unlock a door
^^^^^^^^^^^^^

.. code-block:: python

  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.

.. code-block:: python

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.

.. code-block:: python

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 <https://docs.seam.co/latest/core-concepts/action-attempts>`_.
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

.. code-block:: python

  seam.action_attempts.get(action_attempt_id=action_attempt_id)

Or, to get the current state of an action attempt by ID without waiting,

.. code-block:: python

  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:

.. code-block:: python

  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:

.. code-block:: python

  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:

.. code-block:: python

  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.

.. code-block:: python

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 <https://www.svix.com>`_.
This SDK exports a thin wrapper ``SeamWebhook`` around the svix package.
Use it to parse and validate `Seam webhook events <https://docs.seam.co/latest/developer-tools/webhooks>`_.

Refer to the `Svix docs on Consuming Webhooks <https://docs.svix.com/receiving/introduction>`_ for an in-depth guide on best-practices for handling webhooks in your application.

This example is for `Flask <https://flask.palletsprojects.com/>`_,
see the `Svix docs for more examples in specific frameworks <https://docs.svix.com/receiving/verifying-payloads/how>`_.

.. code-block:: python

  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

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`_.

.. _Angular Commit Message Conventions: https://semantic-release.gitbook.io/semantic-release/#commit-message-format
.. _semantic-release: https://semantic-release.gitbook.io/

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>

.. _Poetry version: https://python-poetry.org/docs/cli/#version
.. _GitHub CLI: https://cli.github.com/
.. _version workflow_dispatch on GitHub Actions: https://github.com/seamapi/python/actions?query=workflow%3Aversion

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.

.. _GPG private key: https://github.com/marketplace/actions/import-gpg#prerequisites
