I am using the Python facebook-sdk client library.
I currently have a short-lived access token obtained from https://developers.facebook.com/tools/accesstoken/ that I copy the code from the site into my code for authentication.
graph = facebook.GraphAPI(access_token)
This token however expires after 60-mins. I am looking to extend this to a 60 day-long lived token so that don't need to manually copy in new every time it expires. I can find numerous answers on how to do this in different formats, however not python (or at least not simply without log in page etc.).
[for reference, the code I will be using is only intended for my use, and as such, I am not looking to create a log in page. I just want to be able to extend the token I already have].
Not sure if this was available in python's FB API when the question was originally asked, but a neater approach to extend the expiry of the access token would be:
graph = facebook.GraphAPI(user_short_lived_token_from_client)
app_id = 'app_id' # Obtained from https://developers.facebook.com/
app_secret = 'app_secret' # Obtained from https://developers.facebook.com/
# Extend the expiration time of a valid OAuth access token.
extended_token = graph.extend_access_token(app_id, app_secret)
print extended_token #verify that it expires in 60 days
here's an edited version , compatible with latest api versions:
import requests
import json
access_token = 'your token' # Obtained from https://developers.facebook.com/tools/accesstoken/
app_id = "your app id" # Obtained from https://developers.facebook.com/
client_secret = "app secret" # Obtained from https://developers.facebook.com/
link = "https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id=" + app_id +"&client_secret=" + client_secret + "&fb_exchange_token=" + access_token
s = requests.Session()
token = s.get(link).content
token=json.loads(token)
token=token.get('access_token')
print token
According to their subsection on extending short lived client tokens, you'll need to take in your short lived client token and, having filled in the relevant app data, send a GET request from your server to the following endpoint:
GET /oauth/access_token?
grant_type=fb_exchange_token&
client_id={app-id}&
client_secret={app-secret}&
fb_exchange_token={short-lived-token}
The response will contain your long-lived access token which can then be passed back to the client or used on your server. If you don't currently have a module for performing HTTP operations, I highly recommend Requests.
