Welcome to the SmartWorks API Client documentation!

Supported Versions

Introduction

This library allows you to interact with the Altair® IoT Studio™ API using Python. The current implementation has support for the following AnythingDB APIs:

Install

From PyPI:

pip install iots

This library officially supports Python 3.7+.

The API class

All the requests are made using an instance of the API class.

from iots import API

api = API()

By default, the API class will use the host https://api.swx.altairone.com. You can also specify a different host:

from iots import API

api = API(host="https://api.my-smartworks.com")

Authentication

There are multiple ways to deal with authentication:

  • Setting an already-exchanged access token:

    api = API(host="api.swx.altairone.com").set_token("my-access-token")

  • Using an OAuth2 client credentials with manual token revocation:

    my_client_id = "some-client-id"
my_client_secret = "the-client-secret"
my_scopes = ["category", "thing"]
api = API(host="api.swx.altairone.com").set_credentials(my_client_id, my_client_secret, my_scopes)

# ...

api.revoke_token()

  • Using an OAuth2 client credentials with automatic token revocation:

    with API(host="api.swx.altairone.com").set_credentials(my_client_id, my_client_secret, my_scopes) as api:
    # ...
    # The token will be revoked when the 'with' block ends
    # or if the code returns or raises an exception

Tokens are automatically refreshed using OAuth2 client credentials, so you don’t need to care about manually refreshing them.

Using the API

The API class uses a nested syntax to allow accessing the API resources, setting the request information with the same structure order that the one used by the API endpoints. Some examples:

space = api.spaces("my-iot-project")

# List Categories
categories = space.categories().get()

# Get a specific Thing
thing = space.things("01GQ2E9M2Y45BX9EW0F2BM032Q").get()

# List Things inside a Category
things = space.categories("Sensors").things().get()

# List Things with query parameters
things = space.things().get(params={"property:temperature": "gt:20"})

# Get all the Property values of a Thing
thing_properties = space.things("01GQ2E9M2Y45BX9EW0F2BM032Q").properties().get()
# ... and access to the 'temperature' Property
temperature = thing_properties['temperature']

# Get a specific Property value
thing_property = space.things("01GQ2E9M2Y45BX9EW0F2BM032Q").properties("temperature").get()
temperature = thing_properties['temperature']

# Set a Property value
thing_property = space.things("01GQ2E9M2Y45BX9EW0F2BM032Q").properties("temperature").update(17.3)

# Create a new Action value
action = space.things("01GQ2E9M2Y45BX9EW0F2BM032Q").actions("updateFirmware").create({"updateFirmware": {"input": "v2.0.0"}})

The models used by the API for request and response data can be found in the iots.models.models module.

💡 Note: The API resources use type hints that should help to understand how to use the API and the data models to define input data or access response data.

Query parameters

To add any query parameter to a request, use the param argument with a dictionary of parameters:

# Return up to 100 Things that have a "temperature" Property with value >= 20
things = space.things().get(params={
  'property:temperature': 'gte:20',
  'limit': 100,
})

Pagination

Some resource listing operations support pagination. You can iterate the response instances to retrieve all the results. If additional API calls are needed to fetch the remaining results, they will be made behind the scenes.

# Get all the Things in a Space
things = space.things().get()

for t in things:
    print(t.uid)

🔮 Future features

  • Add more API resource components.

  • Support for asynchronous requests.
