Manage Facebook Page tab apps via Open Graph API?

Question

I have been investigating the Facebook Open Graph API. There is a \"manage pages\" extended permission which allows publishing to a user\'s Facebook Page news feed/wall via \"im

Answer 1

There's a way to do it via the API. We finally got it to work, after many hours of sweat and tears :)

You can add a tab to a page without leaving your app. Here's a snippet of code that we used for that. We get a list of pages that a user manages, show them in a drop down and ask them to select what page they want to add our "my agent profile" tab to.

And the final product looks something like this - http://www.facebook.com/pages/Jennifer-Anderson-Real-Estate-Agent/185071901564573?sk=app_253956901293839

protected void btnAddTab_Click(object sender, EventArgs e)
{
    if (ddlPage2.SelectedIndex >= 0)
    {
        FaceBookPages page = FaceBookPages.LookupByPageID(long.Parse(ddlPage2.SelectedValue));
        if (page == null)
            throw new NPlaySysException("FaceBookPages is null.");

        AnalyticLog log = new AnalyticLog();
        log.EventID = FBCommon.Events.AddAgentAppTabID;
        log.UserID = UserID;
        log.EventTime = DateTime.Now;
        log.Update();

        string result = FacebookSvc.AddTab(Web.AgentAppID, "me", page.AccessToken);
        if (result.Equals("true"))
        {
            FaceBookPages.UpdateAgentProfileAdded(page.PageID, true);
            List<FaceBookPages> notTabbedPages = FaceBookPages.LookupAgentProfileNotAddedByUserID(UserID);

            imgStep3.ImageUrl = StepDoneImagePath;
            divStep3.Attributes["class"] = StepDoneCssClass;
            phStep3.Visible = false;
            Step3Done = true;
            btnCloseStep3.Visible = false;

            if (notTabbedPages.Count > 0)
                btnEditStep3.Visible = true;
            else
                btnEditStep3.Visible = false;
        }
        else
        {
            lblErrorAddTab.Text = "Failed to add your profile to page.";
            Web.EmailError(string.Format("FacebookSvc.AddTab Failed. result={0}<br />UserID={1}<br />PageID={2}", result, UserID, page.PageID));
        }
    }
}

It is worth noting now, for anyone viewing this question (which is celebrating it's 1st birthday!), that Facebook significantly upgraded their API functionality back in July 2011. You can now Add, Remove, Rename, Reorder and set tabs as Default via the Open Graph API. The blog post is here:

https://developers.facebook.com/blog/post/524/

And the official documentation is here:

https://developers.facebook.com/docs/reference/api/page/#tabs

What Facebook does NOT have yet is a new API method for creating new tab apps, or for changing the tab icon. This is a big step though!

UPDATE: There is bug on the new bug tracker to follow about creating apps in the API if you want to follow it and see what they do: http://developers.facebook.com/bugs/295627350461318

Yes, the best you can do is direct them to the add.php url. You can't do anything to help them remove the app.

The good news is that the user used to have to go through the add process AND physically decide to "enable" the tab by finding it in the tab dropdown on the page. Facebook has recently changed that and it seems that the tab is now immediately enabled after a user adds the app to their page.

As for "has_added_app" that works... sorta. It will tell you if the app is added to the page, but it won't tell you if the tab is enabled. For example, a user can disable the tab but still technically have the app installed on the page. Therefore "has_added_app" will return true even though the tab isn't actually visible.
