(#190) This method must be called with a Page Access Token

[diegocgaona]

I'm having a error when I try to get data:

Error in callAPI(url = x, token = token) : 
  (#190) This method must be called with a Page Access Token

The process of creation of the token is OK, but when I try to access the API data, I receive this error (i'm using the last official version of RFacebook.)

I followed the tutorial (it worked until now): http://thinktostart.com/analyzing-facebook-with-r/

And used:

fb_oauth <- fbOAuth(app_id="XXXXXXXXXX", app_secret="XXXXXXXXXXXXXX", extended_permissions = T)
save(fb_oauth, file="fb_oauth")
load("fb_oauth") 

Then I try to get data, example:

fb_page_fans <- tail(getInsights(object_id = fbpage_id, token = fb_oauth, metric = c('page_fans'), 
                                  period = c('lifetime')), n = 1)

And get the error above... The app is already configured with localhost too.

Any idea? I think I need to create a different token, a Page Token, but I don't know how.

I'm experiencing the same error. It asks me for page access token, but I use the temporary token because the fb_oauth isn't working for a while.

Yes, Facebook had some changes. Can be fixed: -Go to the dashboard of your app -left: click on "Facbook Login" -> Settings -Now paste in the field "Valid OAuth redirect URIs" http://localhost:1410/ -fbOAuth() should now work again in R again

Hi @adrauc !

Thanks! I already did that (because FB show a message about the change in redirect) before I opened the issue. I tried it and other changes, but without success. Here is my config, any other option is wrong?

@diegocgaona you should use getPageToken instead fb_oauth. Try:

token <- getPageToken("yourpage", fb_oauth) fb_page_fans <- tail(getInsights(object_id = fbpage_id, token = token, metric = c('page_fans'), period = c('lifetime')), n = 1)

Many thanks @anankeman ! Worked fine for me, I hope it will help the others.

@diegocgaona @anankeman I'm trying to use the getInsights function and getting the This method must be called with a Page Access Token error.

I tried fb_oauth <- fbOAuth(app_id=..... and get this error

Waiting for authentication in browser...
Press Esc/Ctrl + C to abort
Authentication complete.
Error in oauth2.0_access_token(endpoint, app, code = code, user_params = user_params,  : 
  Bad Request (HTTP 400). Failed to get an access token.

I then tried to use the generated token via https://developers.facebook.com/tools/explorer/ With that token, I'm able to use the getPage function but getInsights give me the following error: This method must be called with a Page Access Token even when the graph api explorer says that I have that permission

Do you know what I'm doing wrong?

@setegonz sorry, i'm not using it anymore. Probably is something with the permissions or API version, Facebook was making my life hard too, changing the API and the access...
