How to post updates to Facebook from PRPC

Facebook side implementation ;

1.       Create Facebook App to interact with the PRPC

a.       Go to facebook developer and create an App

b.      Note down app Secret and App ID for future reference

2.       Obtain authorization code from Facebook.

NOTE:

Sometimes some web browsers are giving an errors so try with difference browsers (for me CROME and IE)

a.        Assemble following URL to get authorization code.

Use your APP ID to replace <APPID> on URL given below.

https://graph.facebook.com/oauth/authorize?client_id=<APPID>&scope=offline_access,read_stream&redirect_uri=http://www.facebook.com/connect/login_success.html

b.      You will redirect to a page where you can allow your application to access your FB account info; click Allow button to give permission to the APP;

c.       Browser will display Success message with  URL contains CODE param in it.

(Eg: http://www.facebook.com/connect/login_success.html?code=

d.      Copy “code=….. “  Parameter and it will use as the authorization code.

3.       Obtain Access token from Facebook.

a.       Assemble following URL to get authorization code.

Use your APP ID, App secret, Authorization Code to replace <APPID>,<Appsecret>,<authorization code> on URL given below.

https://graph.facebook.com/oauth/access_token?client_id= <APPID>
&redirect_uri=http://www.facebook.com/connect/login_success.html&
client_secret=<Appsecret>&code= <authorization code>

b.      This URL will return FB access token on your browser;

Remove “&expires=XXXX” parameter from the end of the token when you use access token.

PRPC side implementation;

1.       Create 4 properties to hold the access token,callback,FB messege and FB ID as below;

       for FB ID use your own FB ID to get posted on your wall.

2.       Create Connect-HTTP rule to connect with FB server;

a.       Set  HTTP Method = GET, HTTP Version =1.1, Response Timeout=30000

b.      Defineà callback, message, target_id ,access_token as parameters on the HTTP rule;

3.       Use previously created activity to call the HTTP-Rule to post FB messege ;

Run and you will see the messege on your facebook wall .
