Tweepy API v2 Authentication - python

How can I test the Tweepy authentication using API v2?
My code below fails to post due to authentication however, is there any other way to test the authentication without invoking posting a Tweet (client.create_tweet) ?
import tweepy
bearer_token = "hidden"
consumer_key = "hidden"
consumer_secret = "hidden"
access_token = "hidden"
access_token_secret = "hidden"
client = tweepy.Client(bearer_token=bearer_token)
client = tweepy.Client(
consumer_key=consumer_key,
consumer_secret=consumer_secret,
access_token=access_token,
access_token_secret=access_token_secret
)
client.create_tweet(text="My first tweet")

You can use any of the methods listed in the documentation here.
I would suggest you to use some read method like get_user:
user = client.get_user('twitter')
print(user.name)
About your authentication itself, the problem is that you have to choose between:
Using the bearer token of your application to get an OAuth 2 "App-Only" authentication. You will have, basically, the same possibilies as an unregistered user on the website.
Using an account's tokens to get an OAuth 1.0a "User Context" authentication. You will then be able to act in the behalf of the user who possesses the tokens that you are using.
But you are trying to do both successively.

I put the bearer token with the other parameters in tweepy.Client, it's not separated and works every time:
import tweepy
client = tweepy.Client(bearer_token="YOUR_BEARER_KEY",
consumer_key="YOUR_CONSUMER_KEY",
consumer_secret="YOUR_CONSUMER_SECRET",
access_token="YOUR_ACCESS_TOKEN",
access_token_secret="YOUR_ACCESS_TOKEN_SECRET")
You can also add wait_on_rate_limit=True to limit your rates in case your not handling them properly.
For a simple test similar to Mickaël's Answer which prints a twitter username to its respective id:
user_get = client.get_user(username='a_twitter_username_here')
user_id = user_get.data.id
print(user_id)
If this does not work then try regenerating your keys and tokens if you can.
This method does not need elevated access.

Spotify - get and change user data with Implicit Flow

I'm trying to implement a simple python client for Spotify api. According to the Spotify's Authorization Guide, the app can be authorized in two ways:
App Authorization: Spotify authorizes your app to access the Spotify Platform (APIs, SDKs and Widgets).
User Authorization: Spotify, as well as the user, grant your app permission to access and/or modify the user’s own data. For information about User Authentication, see User Authentication with OAuth 2.0. Calls to the Spotify Web API require authorization by your application user. To get that authorization, your application generates a call to the Spotify Accounts Service /authorize endpoint, passing along a list of the scopes for which access permission is sought.
CLIENT CREDENTIALS
My first attempt used the app authorization using the oauth2 module from Spotipy, because it requires no token passed, but only client id and client secret, which belong to the app developer.
client.py
import spotipy
from spotipy.oauth2 import SpotifyClientCredentials
class SpotifyWrapper(spotipy.Spotify):
def category_playlists(self, category, limit=50, offset=0):
return self._get('browse/categories/%s/playlists' % category,
limit=limit,
offset=offset)
def get_api_client():
# create a client authentication request
client_cred = SpotifyClientCredentials(
client_id=DevelopmentConfig.SPOTIFY_CLIENT_ID,
client_secret=DevelopmentConfig.SPOTIFY_CLIENT_SECRET
)
# create a spotify client with a bearer token,
# dynamically re-created if necessary
return SpotifyWrapper(auth=client_cred.get_access_token())
Then I would import and declare it here:
spotify_utilities.py
from app.resources.spotify.client import get_api_client
sp = get_api_client()
And in order to make requests and get user playlists, pass it like so:
def get_user_playlist(username, sp):
ids=[]
playlists = sp.user_playlists(username)
for playlist in playlists['items']:
ids.append(playlist['id'])
print("Name: {}, Number of songs: {}, Playlist ID: {} ".
format(playlist['name'].encode('utf8'),
playlist['tracks']['total'],
playlist['id']))
return ids
This works and will get user content, where the user is the app developer.
IMPLICIT FLOW
Now I want to move on to Implicit Flow, whereby the app asks ANY user who uses for access and scopes, and for that a token will be required.
Once I fetch the token using Javascript, I know I can use it to get user data hitting the API with simple requests:
GET_USER_PROFILE_ENDPOINT = 'https://api.spotify.com/v1/users/{user_id}'
GET_USER_PLAYLISTS_ENDPOINT = 'https://api.spotify.com/v1/users/{user_id}/playlists'
def get_user_profile(token, user_id):
url = GET_USER_PROFILE_ENDPOINT.format(id=user_id)
resp = requests.get(url, headers={"Authorization": "Bearer {}".format(token)})
print (len(resp.json()))
return resp.json()
def get_user_playlists(token, user_id):
url = GET_USER_PLAYLISTS_ENDPOINT..format(id=user_id)
resp = requests.get(url, headers={"Authorization": "Bearer {}".format(token)})
print (len(resp.json()))
return resp.json()
but in order to get (and change) user data first I need to use this token to fetch user ID.
Also, by the following example form Spotipy docs, user must provide his username at terminal:
if __name__ == '__main__':
if len(sys.argv) > 1:
username = sys.argv[1]
else:
print("Whoops, need your username!")
print("usage: python user_playlists.py [username]")
sys.exit()
token = util.prompt_for_user_token(username)
if token:
sp = spotipy.Spotify(auth=token)
playlists = sp.user_playlists(username)
After reading the docs from Spotify and Spotify, some things that are still not clear:
Is it possible to get this USER ID from passing the token only?
Must the app user necessarily provide his Spotify username via a form in a browser, besides authorizing the app when authentication is prompted?
Is it possible to tweak the wrapper above and implement a client which contemplates the parameters required for implicit flow? Would simply spotify = spotipy.Spotify(auth=token) work and get current usr data?
Also, by the following example form Spotipy docs, user must provide
his username at terminal:
That's because Spotipy caches tokens on disk. When no cache path is specified by the user the username simply gets appended to the files file extension as seen here. So the username specified is never being transmitted to any Spotify API endpoint.
1) Is it possible to get this USER ID from passing the token only?
Yes, using /v1/me instead of /v1/users/{user_id} will do exactly that assuming you are using an access token generated by Authorization Code flow or Implicit Grant flow.
2) Must the app user necessarily provide his Spotify username via a
form in a browser, besides authorizing the app when authentication is
prompted?
No, as seen in the first paragraph of my answer.
3) Is it possible to tweak the wrapper above and implement a client
which contemplates the parameters required for implicit flow? Would
simply spotify = spotipy.Spotify(auth=token) work and get current usr
data?
Spotipy seems to only use Authorization Code Flow right now. Due to you said you are
trying to implement a simple python client for Spotify api.
you should just implement Implicit Grant flow in your application. This has examples for all three Spotify authorization flows.

Can't register webhook for Twitter Account Activity API [python3]

I'm trying to set up a Twitter app using the Account Activity API, to replace my old set up which used the user streaming endpoint. I want to be able to get DM messages to one user sent to a particular URL in real time.
Following these migration instructions, I've set up a webhook endpoint on my site, as described here. I've checked that process is working, by making sure that when I open https://example.com/webhook_endpoint?crc_token=foo in my browser, I get a token in response.
Now I'm trying and failing to register my webhook. I'm using the following code, and getting a 403 response.
from requests_oauthlib import OAuth1Session
import urllib
CONSUMER_KEY = 'my consumer key'
CONSUMER_SECRET = 'my consumer secret'
ACCESS_TOKEN = 'my access token'
ACCESS_SECRET = 'my access secret'
twitter = OAuth1Session(CONSUMER_KEY,
client_secret=CONSUMER_SECRET,
resource_owner_key=ACCESS_TOKEN,
resource_owner_secret=ACCESS_SECRET)
webhook_endpoint = urllib.parse.quote_plus('https://example.com/webhook/')
url = 'https://api.twitter.com/1.1/account_activity/all/env-beta/'
'webhooks.json?url={}'.format(webhook_endpoint)
r = twitter.post(url)
403 response content: {"errors":[{"code":200,"message":"Forbidden."}]}
I can successfully post a status using the same session object and
r = twitter.post('https://api.twitter.com/1.1/statuses/update.json?status=Test')
What am I doing wrong here?
This turned out to be due to a combination of:
Not having created an environment here: https://developer.twitter.com/en/account/environments as described here: https://developer.twitter.com/en/docs/accounts-and-users/subscribe-account-activity/guides/getting-started-with-webhooks
using the wrong consumer secret in the function that created the token returned at the /webhook endpoint

Facebook Access Token for Single User Application

I'm creating an application on Facebook that will only ever have one user: me. I'm not making a GUI for the application, which means that there's no client side auth.
Is there a way that I can use my username and password or some other app information to get an access token for myself?
I'm familiar with the refresh token flows and everything for OAuth applications for other people, but I've never done this without some sort of Facebook login button, especially on a one person application. I'm happy to hard code in my user information.
I've tried using this:
access_token_url = 'https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=' + config['app_id'] + '&client_secret=' + config['app_secret']
token_response = urllib.urlopen(access_token_url).read()
access_token = token_response.replace('access_token=', '')
session = FacebookSession(
config['app_id'],
config['app_secret'],
access_token,
)
But that doesn't give me an access token specific to my own account, only one for the application itself.
I managed to figure this out. Here's what I did:
I went to the Graph API Explorer (https://developers.facebook.com/tools/explorer) and then got an access token from there for my application.
Once I had the token I used this URL to get a long lived token using that access token:
token_exchange_url = 'https://graph.facebook.com/oauth/access_token?
client_id=APP_ID&
client_secret=APP_SECRET&
grant_type=fb_exchange_token&
fb_exchange_token=ACCESS_TOKEN'
exchange_response = urllib.urlopen(token_exchange_url).read()
access_token = exchange_response.replace('access_token=', '')
access_token = access_token[:access_token.index('&')]
I then saved that access_token and on any subsequent call I can update the access_token using that code whenever in order to make sure it's refreshed.

Oauth client initialization in python for tumblr API using Python-oauth2

I'm new to Oauth. In the past for twitter applications written in Python i used python-oauth2 library to initialize client like this:
consumer = oauth.Consumer(key = CONSUMER_KEY, secret = CONSUMER_SECRET)
token = oauth.Token(key = ACCESS_KEY, secret = ACCESS_SECRET)
client = oauth.Client(consumer, token)
That was easy because twitter provides both CONSUMER and ACCESS keys and secrets. But now i need to do the same for tumblr. The problem is that tumblr provides only CONSUMER_KEY, CONSUMER_SECRET and these urls:
Request-token URL http://www.tumblr.com/oauth/request_token
Authorize URL http://www.tumblr.com/oauth/authorize
Access-token URL http://www.tumblr.com/oauth/access_token
Using this data how can i initialize client to access tumblr API?
UPD
jterrace suggested a code i tried to use before. The problem with it is oauth_callback. If i don't specify any, api returns error "No oauth_callback specified", but if i do specify some url like "http://example.com/oauthcb/" and follow the link http://www.tumblr.com/oauth/authorize?oauth_token=9ygTF..., then press Allow button, tumblr doesn't show any PIN code page, it immediately redirects to that callback url, which is useless since it's desktop application. Why PIN code isn't shown?
UPD 2
Tumblr API doesn't support PIN code authorization. Use xAuth instead - https://groups.google.com/group/tumblr-api/browse_thread/thread/857285e6a2b4268/15060607dc306c1d?lnk=gst&q=pin#15060607dc306c1d
First, import the oauth2 module and set up the service's URL and consumer information:
import oauth2
REQUEST_TOKEN_URL = 'http://www.tumblr.com/oauth/request_token'
AUTHORIZATION_URL = 'http://www.tumblr.com/oauth/authorize'
ACCESS_TOKEN_URL = 'http://www.tumblr.com/oauth/access_token'
CONSUMER_KEY = 'your_consumer_key'
CONSUMER_SECRET = 'your_consumer_secret'
consumer = oauth2.Consumer(CONSUMER_KEY, CONSUMER_SECRET)
client = oauth2.Client(consumer)
Step 1: Get a request token. This is a temporary token that is used for
having the user authorize an access token and to sign the request to obtain
said access token.
resp, content = client.request(REQUEST_TOKEN_URL, "GET")
request_token = dict(urlparse.parse_qsl(content))
print "Request Token:"
print " - oauth_token = %s" % request_token['oauth_token']
print " - oauth_token_secret = %s" % request_token['oauth_token_secret']
Step 2: Redirect to the provider. Since this is a CLI script we do not
redirect. In a web application you would redirect the user to the URL
below.
print "Go to the following link in your browser:"
print "%s?oauth_token=%s" % (AUTHORIZATION_URL, request_token['oauth_token'])
# After the user has granted access to you, the consumer, the provider will
# redirect you to whatever URL you have told them to redirect to. You can
# usually define this in the oauth_callback argument as well.
oauth_verifier = raw_input('What is the PIN? ')
Step 3: Once the consumer has redirected the user back to the oauth_callback
URL you can request the access token the user has approved. You use the
request token to sign this request. After this is done you throw away the
request token and use the access token returned. You should store this
access token somewhere safe, like a database, for future use.
token = oauth2.Token(request_token['oauth_token'], request_token['oauth_token_secret'])
token.set_verifier(oauth_verifier)
client = oauth2.Client(consumer, token)
resp, content = client.request(ACCESS_TOKEN_URL, "POST")
access_token = dict(urlparse.parse_qsl(content))
print "Access Token:"
print " - oauth_token = %s" % access_token['oauth_token']
print " - oauth_token_secret = %s" % access_token['oauth_token_secret']
print
Now that you have an access token, you can call protected methods with it.
EDIT: Turns out that tumblr does not support the PIN authorization method. Relevant post here.
If you just want to gain an access-token/secret to sign, you could just setup your callback URL as: http://localhost/blah
Fireup the CLI-app (after modifying the callback-url, secret and token ofcourse)
Follow the link in your browser
Allow app
View addressbar of the page you've been redirected to in the browser after allowing your app. It should look something like:
http://localhost/blah?oauth_token=xxxxxxxxxxxxxxxxxxxxxxxxxx0123456789ABCDEFGHIJKLMN&oauth_verifier=XXXXXXXXXXXXXXXXXXXXXXXXX0123456789abcdefghijklmn
Use the value of the query-parameter 'oauth_verifier' as your PIN:
XXXXXXXXXXXXXXXXXXXXXXXXX0123456789abcdefghijklmn
The CLI should print out your oauth-token and oauth-token-secret.
HTH! Got this working for tumblr in this way :)
Have a look at https://github.com/ToQoz/Pyblr
It uses oauth2 and urllib to provide a nice wrapper for exactly what you're trying to do.
It seems that what you're trying to do is access an OAuth 1 API with an OAuth 2 client.
See https://github.com/simplegeo/python-oauth2 and look for “three-legged OAuth example”.
had this problem with oauth2 and facebook.
#deepvanbinnen's answer lead me into the right direction.
facebook actually redirected to a page similar to this
'http://localhost/blah?code=AQAXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX#_=_'
using then the ' AQAXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX#_=_ as the PIN actually got me the access to the requested facebook account.
#jterrance's answer is good. However, realize it is a one _time_ manual procedure to get the access token. The access token is the key that you use for all subsequent API calls. (That's why he recommends saving the access token in a database.) The string referred to as 'PIN' (aka the verification key) is not necessarily a number. It can be a printable string in any form. That verification key is displayed on the authorization page at the URL printed in step 2 then pasted into the prompt for a the 'PIN'.

Tumblr API Blog methods return 401 "Not Authorized", but User methods works perfect

So, there is a code that uses xAuth authentication to call tumblr API methods:
import urllib
import urlparse
import oauth2 as oauth
consumer_key = "..."
consumer_secret = "..."
consumer = oauth.Consumer(consumer_key, consumer_secret)
client = oauth.Client(consumer)
resp, content = client.request('https://www.tumblr.com/oauth/access_token', "POST", urllib.urlencode({
'x_auth_mode': 'client_auth',
'x_auth_username': '...#yandex.ru',
'x_auth_password': '...'
}))
token = dict(urlparse.parse_qsl(content))
print token
token = oauth.Token(token['oauth_token'], token['oauth_token_secret'])
client = oauth.Client(consumer, token)
response, data = client.request('http://api.tumblr.com/v2/blog/good.tumblr.com/followers', method='GET')
print data
It works perfect with User methods from tumblr API that require OAuth authentication.
But it fails when i try to call any Blog method with OAuth authentication (/followers for example):
{"meta":{"status":401,"msg":"Not Authorized"},"response":[]}
Except one thing. If i use my blog name as {base-hostname} parameter it works without any errors.
Weird. How is that possible? Is something wrong with the code?
Well that is because your OAuth access token grants you access to your blogs. OAuth can't give you permission to access Blog methods that you do not own because then you could post to them.
When you make POST request the enctype must be "multipart/form-data".
I had the same problem with Zend_Oauth (php), but is resolved now.
