Python Requests Works in Console, but not In App

I built a Python Script which is meant to upload data to an application called Intercom, using the python requests library. The idea is to insert a brand new field into the custom attributes with data we would need to key off for our auto-messaging.

The script is very long, but the method that is breaking is below:

def post_user(self, input_user, session=None):
    """
    :param user: a JSON object with all the user pieces needed to be posted to the endpoint
    :param session: a Requests session to be used. If None we'll create one
    """
    if not session:
        session = self.create_requests_session()
    else:
        session = session

    # JSON encode the user
    payload = json.dumps(input_user, sort_keys=True, indent=2, separators=(',', ': '))

    print(payload)  # DEBUG CODE

    # Post the data to endpoint
    response = session.post(self.endpoint, data=payload)

    # This will raise a status code on a bad status code
    response.raise_for_status()

Below is also the method for create_requests_session():

def create_requests_session(self):
    """
    Start a requests session. Set Auth & Headers so we don't have to send it with each request
    :return: A new requests.Session object with auth & header values prepopulated.
    """

    session = requests.Session()
    session.auth = (self.app_id, self.api_key)
    session.headers = {'Content-Type': 'application/json', 'accept': 'application/json'}

    return session

When I run the entire script and step through the first input_user it comes in as a dict, looking like. (Note: The data is anonymized, but the structure remains the exact same):

 {'user_id': '123456', 
  'email': '[email protected]', 
  'custom_attributes': {
      'test_cell' : 'Variation'}
 }

However, after delivering the user to json.dumps(user) and then sending it through a POST request, I got back a 404 error.

Here's the weird part. I sent this exact same user with the exact same JSON, except I created all of the parts using the Python Console (note, some lines are hidden to maintain user data anonymity):

In[82]: sesh = requests.session()
In[86]: header
Out[86]: {'Content-Type': 'application/json', 'accept': 'application/json'}
In[87]: sesh.headers = header
In[89]: payload = json.dumps(update_user)
In[91]: response = sesh.post(endpoint, data=payload)
In[92]: response
Out[92]: <Response [200]>

At this point, I'm completely lost. I've attempted to set up a proxy to try and compare the requests byte by byte, but haven't had much luck with that. Any help or insight is greatly appreciated.

Solution

Have you ensured that your authentication is valid?

session.auth = (self.app_id, self.api_key)

In particular, the app_id should be set to the one corresponding to the API Key (so the test app's app_id if you're using a test app).

If Intercom receives an app id it does not recognise it (currently) returns a 404, which is what you're seeing. This should be fixed now to return a 401.
