Misfit API Python Client Implementation

Quick Start

Install with pip install misfit

Create an app with “Application Domain” set to http://127.0.0.1:8080/. Now use the “App key” and “App secret” in the following command:

misfit authorize --client_id=<app_key> --client_secret=<app_secret>

That will save the necessary credentials for making further API calls to a file called “misfit.cfg”. These credentials should be kept private. You can use same the command-line client to access everything in the Resource API. You can also access the same resources using the Python API:

>>> from misfit import Misfit
>>> misfit = Misfit(<client_id>, <client_secret>, <access_token>)
>>> print(misfit.profile())
{u'gender': u'male', u'birthday': u'1981-07-18', u'userId': u'scrubbed', u'name': u'Brad Pitcher'}

Slow Start

After you have installed and created your misfit app you can authorize and use the API with your own web server rather than the built-in CherryPy server like so:

>>> from misfit.auth import MisfitAuth
>>> auth = MisfitAuth(<client_id>, <client_secret>, redirect_uri=<redirect_uri>)
>>> auth_url = auth.authorize_url()

Now redirect the user to auth_url. When control returns to your web server at the endpoint specified in <redirect_uri>, you will receive code and state GET params you can pass to the fetch_token method, which will return access_token, which is needed for further API calls:

>>> access_token = auth.fetch_token(<code>, <state>)
>>> from misfit import Misfit
>>> misfit = Misfit(<client_id>, <client_secret>, <access_token>)
>>> print(misfit.profile())
{u'gender': u'male', u'birthday': u'1981-07-18', u'userId': u'scrubbed', u'name': u'Brad Pitcher'}

Notifications

This library also includes some basic tools to ease notification handling. To use Misfit’s Notification API with your web application, the first thing you need to do is set up an endpoint to accept POST requests on the domain you specified when you created your app, like http://example.com/misfit/notification/ if your application domain is http://example.com.

Now, when you handle the request, just create a MisfitNotification object with the body of the request as an argument. The MisfitNotification constructor automatically verifies the signature of the SNS message so you can feel secure in the knowledge that the message is legitimate. It will raise cryptography.exceptions.InvalidSignature if the signature is not valid.

The MisfitNotification class handles both subscription confirmation messages and regular update messages. You can check the type of message by looking at the Type attribute, which will be either 'SubscriptionConfirmation' or 'Notification'. For a Notification message, you will find the updates as a list in a Message attribute. After you process the updates (which can take no longer than 15 seconds) make sure to respond with an HTTP status of 200, otherwise SNS may try to deliver it again. A full workflow should look something like this:

>>> from misfit.notification import MisfitNotification
>>> notification = MisfitNotification(content)
>>> if notification.Type == 'Notification':
>>>    for message in notification.Message:
>>>        if message['type'] == 'goals':
>>>            # Handle goal update
>>>        # Handle other message types
>>> # Give an empty response with a 200 status code

Once you have your endpoint up and running, go to your app and add your endpoint as a subscription hook URL, making sure the format is json. Click “Test Endpoint” and if all goes well, the verification should seamlessly take place. If not, please file an issue and we will try and help you debug. Now switch on all the resources you would like to receive and click “Update”. Soon you will be receiving Misfit notifications!
