Hi, Aritra. I'm a Pega product manager working with Facebook and Twitter for the Customer Service application, so my team and I also use the Facebook data set. I'm not very familiar with the older Pega platform pieces, but more recent versions of Pega include a button in the Data Set rule that can test the Facebook connection there, which would be very convenient in this case.

The error message you're getting is pretty clear that it is having a problem with the app ID, App secret, or perhaps the page token. So if you haven't already done this, you might want to validate these directly from a browser by creating the URL defined in the middle of the PDN article How to post updates to Facebook from Pega Platform (which you already know about), in the section called "Obtain an authentication token."

https://graph.facebook.com/oauth/access_token?
 client_id=APP_ID
 &redirect_uri=http://www.facebook.com/connect/login_success.html&
 client_secret=APP_SECRET&code=CODE_FROM

When you paste this URL into a browser, you should see the access token info (that is in the screen shot in the PDN article). If you don't, then there is something wrong with the App ID and/or App Secret. If you do see the access token, then that would point to a problem in Pega.

Hi, Aritra,

It's good that you've figured out how to get connectivity to the Facebook data. Have you been able to get data after the NLP step?

The steps you outlined look good. Digging into the issue further would require more of an engineering resource.

Getting below error message when copying "https://graph.facebook.com/oauth/authorize?client_id=ProvidedmyappID&scope=offline_access,read_stream&redirect_uri=http://www.facebook.com/connect/login_success.html" in browser address bar.Can anyone please suggest what i am doing wrong here.

Thanks in advance.
