Callback URL not being invoked

[karthikarul20]

I am trying to integrate the FITBIT api in which i managed to get auth_token and redirect the user for Authorization. While creating the Fitbit() i am setting the callback_uri. But, after completing the authorization the FitBit API is not invoking my callback service.

Please pardon my ignorance and help me to deal with this issue.

I am using Web2Py framework and below is my code.

def index():
    callback_uri=getHost()+URL('callback','completeAuthorization')
    from fitbit import Fitbit
    from requests_oauthlib import OAuth1Session
    client_kwargs = {
            'client_key': 'c8ca82f890c44a969cc3524b7c342e8b',
            'client_secret': '7bf3dd8b933144e2bbe2c7971d46e3ae',
            'user_key': None,
            'user_secret': None,
            'callback_uri': callback_uri
        }
    fb = Fitbit(**client_kwargs)
    retval = fb.client.fetch_request_token()
    url='https://api.fitbit.com/oauth/authorize?oauth_token='+retval.get('oauth_token')+'&callback_uri='+callback_uri
    print callback_uri
    redirect(url)
    return dict(message=url)

def completeAuthorization():
    print request
    print request.vars
    print request.args
    oauth_token=request.vars.oauth_token
    oauth_verifier=request.vars.oauth_verifier
    return locals

def getHost():
    request_host_uri = URL(args=request.args, vars=request.vars, host=True)
    request_uri = URL(args=request.args, vars=request.vars, host=False)
    parts = request_host_uri.split(request_uri)
    host = parts[0]
    return str(host)

EDIT(brad): I wrapped your code to make it easier to read

Hi @karthikarul20
I think I am to blame for your troubles. If there was better documentation it probably would be easier for you.
So a couple things:

• The authorize url you are using is wrong, the base should be www.fitbit.com instead of api.fitbit.com.
• There is no need to build the authorize url yourself, we have a function for that; authorize_token_url. I've included some example code below.
• The most recent version of the library changed the user_key and user_secret kwargs to resource_owner_key and resource_owner_secret respectively, but None is the default so they don't need to be specified here.
• Fitbit will only redirect to your callback_uri if the app type on dev.fitbit.com is "Browser"
• Now that you have publicly posted your Fitbit app key/secret, I highly recommend you reset them.

import webbrowser
from fitbit import Fitbit

client_kwargs = {
    'client_key': 'c8ca82f890c44a969cc3524b7c342e8b',
    'client_secret': '7bf3dd8b933144e2bbe2c7971d46e3ae',
    'callback_uri': 'http://127.0.0.1/test'
}
fb = Fitbit(**client_kwargs)
fb.client.fetch_request_token()
webbrowser.open(fb.client.authorize_token_url())

Let me know how that works out for you.

Thanks Brad. App type on dev.fitbit.com was the culprit. It was set as Desktop and now it works fine.
Also i have reset the client_key and client_secret as you recommended.
