Real time Instagram API with Django
This is a quick tutorial on howto use the Instagram API with Django. We will be tracking a specific hashtag in real time and receiving the notifications from Instagram API to our defined endpoint.
Python Instagram package
Install the python Instagram package through pip, this is the official supported python bindings for Instagram API.
pip install python-instagram
Register a Developer account
You will need to register with Instagram even if your sole intention is to use their API, you still need to have a valid account. Currently the only way of registering an account is through the mobile applications, the website is not allowing to register for Instagram.
Once registered you will need to create an application in your developer account, this will give you a CLIENT_ID and CLIENT_SECRET which will be used to interact with the API.

Pubsubhubub and Real time API
The instagram realtime API follows the Pubsubhubub protocol, the idea is that you have subscriptions and once there are events you will receive a push notification, in this case it would be a HTTP post request to our server.
You can read more about the real time API https://instagram.com/developer/realtime/
Django and Pubsubhubub Subscription
The following code is a basic implementation of the real time Instagram API handler, as discussed previously the Instagram API uses the Pubsubhubub protocol, you first need to setup the handlers then subscribe for events, once everything is done you should start receiving events
Your urls.py should look like this
And your your views.py should look like this
from django.http import HttpResponse from django.views.decorators.csrf import csrf_exempt from instagram import subscriptions def process_tag_update(update): print 'Received a push: ', update reactor = subscriptions.SubscriptionsReactor() reactor.register_callback(subscriptions.SubscriptionType.TAG, process_tag_update) @csrf_exempt def realtime_callback(request): # GET method is used when validating the endpoint as per the Pubsubhubub protocol if request.method == 'GET': mode = request.GET.get('hub.mode') challenge = request.GET.get('hub.challenge') verify_token = request.GET.get('hub.verify_token') if challenge: return HttpResponse(challenge) # POST event is used to for the events notifications else: x_hub_signature = request.META.get('HTTP_X_HUB_SIGNATURE', '') raw_response = request.body try: reactor.process(settings.INSTAGRAM_CLIENT_SECRET, raw_response, x_hub_signature) except subscriptions.SubscriptionVerifyError: print 'Signature mismatch' return HttpResponse('')
Finally let’s subscribe to the Instagram real time API and start receiving events for given hashtag, you only need to subscribe once so make sure you just run this code in the Django’s shell (manage.py shell) rather than in your views.py.
Use the previously generated CLIENT_ID and CLIENT_SECRET, in this case we are subscribing to any picture tagged with a hashtag #paris
from instagram.client import InstagramAPI api = InstagramAPI(client_id='YOUR_CLIENT_ID', client_secret='YOUR_CLIENT_SECRET') api.create_subscription(object='tag', object_id='paris', aspect='media', callback_url='http://yourdomain.com/realtime_callback')
Hopefully this should give you enough playground to start using the Instagram’s real time API!
