Post on Facebook Page using Force.com Facebook Toolkit [closed]

Question

Using Facebook Toolkit i am able to get data of user. But is it possible to post data on Facebook page and get data from Facebook page. Please provide me the relevant code for posting on Facebook Page.

Answer 1

The first thing you would do would be to obtain the Facebook page ID - this is simply the bit of the page URL after https://www.facebook.com/ - so, the Developer Force Facebook page ID is forcedotcom.

Now, to get the posts (feed) for that page:

posts = new FacebookPosts(accessToken, pageid +'/feed', null);

To post to that page:

FacebookPublish.postToWall(accessToken, pageid, new Map<String, String>{'message' => message});

You can edit the sample page controller in the Facebook Toolkit to try this out - look for myPosts and postToFeed() and change me to a page ID:

public FacebookPosts myPosts {
    get {
        try {
            String accessToken = getAccessToken();

            if (accessToken != null) {
                myPosts = new FacebookPosts(accessToken, 'forcedotcom/feed', null);
            }               
        } catch (Exception e) {
            error = e.getMessage();
        }

        return myPosts;
    } set;
}

// Further down...

public PageReference postToFeed() {
    error = null;

    try {
        if (message != null) {
            FacebookPublish.postToWall(getAccessToken(), 'forcedotcom', new Map<String, String>{'message' => message});
        }

        message = null;
    } catch (Exception e) {
        error = e.getMessage();
    }

    return null;
}
