Posting to a page wall with the Facebook SDK in Python

I’ve been developing in Python for quite a few months now and the need to develop a Facebook app has arrived.

So in my app I had the need to post content to a Fan Page wall and after a couple of tests I noticed the content being posted on the Fan Page on behalf of the Page owner and not the page itself.

To fix that I had to make the following changes inside the if condition where it checks for the arguments being posted:

if post_args is not None:
  if post_args['page_token']:
    post_args["access_token"] = post_args['page_token']#self.access_token
  else:
    post_args["access_token"] = self.access_token
else:
  args["access_token"] = self.access_token

So now I’m checking for an extra argument in this case page_token, if it’s set we use that token instead of the token that was used to initialize the Facebook Graph object.

With this changes in place we add the extra parameter page_token to our attachment and it shoud work as expected, with the content being posted on behalf of the page.

graph = facebook.GraphAPI(str(access_token))
attach = {
  "name": 'Hello world',
  "link": 'http://www.example.com',
  "caption": 'test post',
  "description": 'some test',
  "picture" : 'http://www.example.com/picture.jpg'
  "page_token" : str(page_token)
}
msg = 'New content posted'
post = graph.put_wall_post(message=msg, attachment=attach,profile_id=str(page_id))
  if post:
    return 'posted'
