Python SDK for LaunchKey API

For use in implementing LaunchKey.

Description

Use to more easily interact with iovation's LaunchKey API.

A more in-depth look at this SDK can be found at the official docs.

Installation

$ easy_install launchkey

or

$ pip install launchkey

Usage

Using LaunchKey Clients

The LaunchKey SDK is broken into credential based factories with access to functionality based clients.

Factories

Factories are based on the credentials supplied. The Organization Factory uses Organization credentials, the Directory Factory uses Directory credentials, and the Service Factory uses Service credentials. Each factory provides clients which are accessible to the factory. The availability is based on the hierarchy of the entities themselves. Below is a matrix of available services for each factory.

Factory	Organization Client	Directory Client	Service Client
Organization	Yes	Yes	Yes
Directory	No	Yes	Yes
Service	No	No	Yes

Using individual clients

from launchkey.factories import ServiceFactory, DirectoryFactory

directory_id = "37d98bb9-ac71-44b7-9ac0-5d75e31e627a"
directory_private_key = open('directory_private_key.key').read()
service_id = "9ecc57e0-fb0f-4971-ba12-399b630158b0"
service_private_key = open('service_private_key.key').read()

directory_factory = DirectoryFactory(directory_id, directory_private_key)
directory_client = directory_factory.make_directory_client()

service_factory = ServiceFactory(service_id, service_private_key)
service_client = service_factory.make_service_client()

Using a hierarchical client

from launchkey.factories import OrganizationFactory

organization_id = "bff1602d-a7b3-4dbe-875e-218c197e9ea6"
organization_private_key = open('organization_private_key.key').read()
directory_id = "37d98bb9-ac71-44b7-9ac0-5d75e31e627a"
service_id = "9ecc57e0-fb0f-4971-ba12-399b630158b0"
user = "my_unique_internal_identifier"

organization_factory = OrganizationFactory(organization_id, organization_private_key)
directory_client = organization_factory.make_directory_client(directory_id)
service_client = organization_factory.make_service_client(service_id)

Linking And Managing Users

In order to link a user you will need to start the linking process then display the qrcode to them, give them the code, or both.

link_data = directory_client.link_device(user)
linking_code = link_data.code
qr_url = link_data.qrcode

If desired you can retrieve the user's devices and unlink then directly from the SDK

devices = directory_client.get_linked_devices(user)
directory_client.unlink_device(user, devices[0].id)

You can also end all of a user's sessions

directory_client.end_all_service_sessions(user)

Logging A User In

Create an auth request to initiated the login process

auth_request_id = service_client.authorize(user)

Using Dynamic Policies

from launchkey.entities.service import AuthPolicy
# Require 2 factors and don't allow any jailbroken or rooted devices
policy = AuthPolicy(any=2, jailbreak_protection=True)
# Also make it so the user can only log in from the Portland area
policy.add_geofence(latitude=45.48805749706375, longitude=-122.70492553710936, radius=27500)
auth_request_id = service_client.authorize(user, policy=policy)

Check whether a response has been received and check whether it has been authorized

from launchkey.exceptions import RequestTimedOut
from time import sleep
response = None
try:
    while response is None:
        response = service_client.get_authorization_response(auth_request_id)
        if response is not None:
            if response.authorized is True:
                # User accepted the auth, now create a session
                service_client.session_start(user, auth_request_id)
            else:
                # User denied the auth request
        else:
            sleep(1)
except RequestTimedOut:
    # The user did not respond to the request in the timeout period (5 minutes)

When a user logs out

service_client.session_end(user)

Dealing with Webhooks

Webhooks can be used in opposition to polling. This means we will hit your app on either an auth response or logout request.

You will use the same handle_webhook method for both login and logout.

Note that request.headers must be a dictionary like object.

from flask import request
from launchkey.entities.service import AuthorizationResponse, SessionEndRequest
package = service_client.handle_webhook(request.data, request.headers)
if isinstance(package, AuthorizationResponse):
    if package.authorized is True:
        # User accepted the auth, now create a session
        service_client.session_start(user, auth_request_id)
    else:
        # User denied the auth
elif isinstance(package, SessionEndRequest):
    # The package will have the user hash, so use it to log the user out based on however you are handling it
    logout_user_from_my_app(package.service_user_hash)
