Publish pictures on Facebook page events using python - python

I'm trying to publish pictures on Facebook events under Facebook pages I own as that owning page using python. I am attempting to do so as the admin of an app.
The best understanding I have of the process (obviously not good enough) is that it is a two step process: 1) get page_token for target page using user_token (have a long-lived one) 2) use page_token to publish content.
Something like this:
def getFbGraph(accessToken=user_token):
return facebook.GraphAPI(access_token=accessToken)
page_token = getFbGraph().get_object(pageID, fields=['access_token'])
getFbGraph(page_token).put_object(parent_object=eventID, connection_name='photos', message='This is my caption', url=imgUrl)
That gets me the following error message:
facebook.GraphAPIError: Invalid OAuth access token
If instead I try to put the photo as a user (i.e. without the pageToken) I get the following message:
facebook.GraphAPIError: (#200) Requires extended permission: publish_actions
Is there no way for the admin of a page and an app to programmatically post allowed content? I don't need other FB users to be doing that (hence need to go through the publish_actions permissions) and I own all the pages I'm posting to.
Many thanks in advance for your comments.

How to get FB access_token from python console app?

I have a console application that should get a list of people who liked my page.
As far as I understood I should run something like
QUERY = 'SELECT user_id FROM like WHERE object_id=__MY_PAGE_ID__'
url = "https://graph.facebook.com/fql?q=" + QUERY
data = requests.get(url)
but iI need to use some access token, and I don't understand what kind of. I have log and pass for user with administrative rights on this PAGE. But thay said that I can't get user token without interacting with web browser.
So I need to use app? Should I create it before somehow? How can you allow this app to get admin account on the page?
Thanks

Posting to my Facebook page from my web app in production

I installed Django Facebook and I am using this method to post to a Page:
from open_facebook.api import OpenFacebook
graph = OpenFacebook("my_access_token")
graph.set('me/feed', message='hello world')
It's working on my local dev machine when I am logged in to my Facebook account. It stops working as soon as I sign out and I get this message:
OAuthException: Error validating access token: The session is invalid because the user logged out. (error code 190)
I got my access token from Graph API Explorer by passing /me/accounts
So the question, how do I make my code work on production when of course I'll not be logged in?
Please note that I'll only be posting to a Page that I own.
If you want to use 'me/feed' offline;
You can use the APP Access Token, once you've authorized the app and call USER_ID/feed to post.
Note: use user_id instead of me- me is only used when a user is in session, but you want to do the action after logout.
To get the app access token,
GET /oauth/access_token?
client_id={app-id}
&client_secret={app-secret}
&grant_type=client_credentials

How to programmatically post to my own wall on Facebook?

I'm trying to make a simple program to post something to my wall on Fcebook in Python. I tried using this example from pythonforfacebook:
import facebook
oauth_access_token = "****"
graph = facebook.GraphAPI(oauth_access_token)
me = "****"
profile = graph.get_object(me)
graph.put_object(me, "feed", message="I am writing on my wall!")
I tried going to the developer center and making an App. For "Select how your app integrates with Facebook",I chose "Website with Facebook Login" (I don't actually have a website, I just have a program that should post to my facebook wall, but this is the closest option that matches what I want to do...).
However, when I run this, it says:
$ python a.py
Traceback (most recent call last):
File "a.py", line 7, in <module>
graph.put_object(me, "feed", message="I am writing on my wall!")
File "/usr/lib64/python2.7/site-packages/facebook.py", line 140, in put_object
post_args=data)
File "/usr/lib64/python2.7/site-packages/facebook.py", line 298, in request
raise GraphAPIError(response)
facebook.GraphAPIError: (#200) The user hasn't authorized the application to perform this action
How can I log in as the user and authorize my App? Am I even taking the right approach? I don't actually have a website, I just have a program, for the website field I literally entered "http://google.com" and it worked.
I made it work by getting a new token with permissions to post on my wall (specifically, the "publish_actions" permission). I did this by using the Graph API Explorer, selecting my application in the dropdown menu, pressing "Get Access Token" and checking "publish_actions". The only problem is the token expires after an hour.
You must authorize the user for publish_action/publish_stream permission to post on your wall.
If your only task is to post on the wall/ get the basic info; you can use the APP Access Token instead of user access token for performing the action once you've authorized the app. To get the App Access Token, you can uuse-
GET /oauth/access_token?
client_id={app-id}
&client_secret={app-secret}
&grant_type=client_credentials
Or, directly from here. But do not hard code it in your app (for security reasons)
Or, if you want to perform other actions too on the user's behalf you can extend the user token to 2 months validity. Read here for more details
For those of who stumble upon this post after April 24th, Facebook has stopped support for such API calls.
As of April 24,2018, the publish_actions permission has been removed. Please see the Breaking Changes Changelog for more details. To provide a way for your app users to share content to Facebook, we encourage you to use our Sharing products instead.

Posting to Facebook App page wall as the App Page in python

I am trying make a post on my apps page wall as if it is coming from the app page (not another user) After researching I seem to find no solution that actually works!
I have tried to follow the documentation here:
I then get my 'access_token_page' by getting it from:
https://graph.facebook.com/oauth/access_token?client_id=APP_ID&client_secret=CLIENT_SECRET&grant_type=client_credentials
Then using the facebook python api I try:
graph1 = facebook.GraphAPI(access_token_page)
graph1.put_wall_post(fbmessage, attachment, profile_id=APP_PAGE_ID)
However this just returns the following facebook error:
*** GraphAPIError: (#200) The user hasn't authorized the application to perform this action
Any ideas on what I am missing? Remember, I am looking to have the App Page make a post to itself, not have a post be generated from another username.
Thank you!
What you had done is using App Access Token to publish to page.
You should using Page Access Token to post on page admin behalf instead. User Access Token is works too but it's a bug as reported at https://developers.facebook.com/bugs/647340981958249, so it's not recommended to use User Access Token by this time of writing.
As documented at https://developers.facebook.com/docs/reference/api/page/#page_access_tokens:
Page Access Tokens
To perform the following operations as a Page, and not the current
user, you must use the Page's access token, not the user access token
commonly used for reading Graph API objects. This access token can be
retrieved by issuing an HTTP GET to /USER_ID/accounts with the
manage_pages permission.
More info about different type of access token please visit https://developers.facebook.com/docs/facebook-login/access-tokens/
Try Django Facebook:
https://github.com/tschellenbach/Django-facebook
This will deal with many of your API problems.
You need the page access token, see here:
https://developers.facebook.com/docs/facebook-login/access-tokens/
Ask for manage_pages as an extra permission
After getting that setup, simply do:
user_graph = OpenFacebook(user_access_token)
response = user_graph.get('me/accounts')
# turn the response to a dict, and be sure to get the page you want
page_access_token = response['data'][0]['access_token']
graph = OpenFacebook(page_access_token)
graph.set('me/feed', message='helloworld')

Obtaining an Access_token to read Page Insights

I've been working on using python to get access to Facebook insights information. I was able to get public information (e.g. 'likes' from cocacola's page) in addition to app insights for apps that I have developed.
Because I am the admin and developer for both pages and apps, when I go to facebook.com/insights I will see a section for pages and a section for apps. I want to be able to get insights for both from the graph api and store them on my personal database. Getting the app insights were not difficult. I obtained my app_id and app_secret when I created my app and then followed the process under App Login at this page http://developers.facebook.com/docs/authentication/. This gave me an app access_token which I could use to get app insights.
When attempting to do the same for pages, I have had more trouble. As many previous posts have mentioned, most of the facebook documentation has to do with a facebook app getting an access_token to manage or read insights from a page. I understand that this is useful for apps that interact with a user's page. However, my instinct says that I should be able to get an access token with read_insights for a page that I am the administrator of without having to go through an external app.
The only way that I've been able to read the insights for my page has been using the Graph Api Explorer. I used the Explorer to obtain an access_token (through the access_token button, allowing the Explorer to access my personal data and requested manage_pages and read_insight extended permision). Then I followed the instructions under Page Login at the /docs/authentication/ page that I posted above, to get an access_token for the facebook page I administer. Then I could finally run https://graph.facebook.com/PAGE_ID/insights?access_token=RETRIEVED_TOKEN. However, this is an incredibly cumbersome way of finding the access_token. Is there a way to get this token that is less cumbersome? Thanks for your help. I've been struggling with this for quite a while.
I've also included the code that I used to get the access token for my app.
def get_access_token():
args = dict(client_id=FACEBOOK_APP_ID, client_secret=FACEBOOK_APP_SECRET, grant_type="client_credentials" )
url = "https://graph.facebook.com/oauth/access_token?" + urllib.urlencode(args)
response = urlparse.parse_qs(urllib.urlopen(url).read())
access_token = response['access_token'][0]
return access_token
Why not using classic way:
Create an app and login to it using facebook (JS SDK for example), with the offline_access and read_insights permission.
The offline_access will give you a permanent access_token that you can use to access the insights anytime you want.
The JS SDK (method FB.login) will return an object, containing the access_token you need.
