Facebook: send an app invitation

Question

How can I send an invitation to use an app with Graph API? I looked at the reference, and can't find something that fits. Any clue?

It's not possible for now. The old fbml and the new requests dialog are the only way to send requests. — DannyKK, May 20 '11 at 14:28
@Traroth: that's correct. The only way to send a direct invite with a POST to {user_id}/apprequests, and the user has to have already installed your application and given permissions to access that endpoint. — typeoneerror, Sep 06 '11 at 16:16

A HTML/javascript example:

<html>
  <head>
  <title>My Great Website</title>
  </head>
  <body>
  <div id="fb-root"></div>
  <script src="http://connect.facebook.net/en_US/all.js">
  </script>
  <script>
    FB.init({ 
      appId:'YOUR_APP_ID', cookie:true, 
      status:true, xfbml:true 
    });

    FB.ui({ method: 'apprequests', 
      message: 'Here is a new Requests dialog...'});
  </script>
  </body>
</html>

You can associate the javascript to click event of a link, etc.

You can find the details here:

Not sure that's the same as an invitation – izb Oct 26 '11 at 14:04 — izb, Oct 26 '11 at 14:04

If you need to use restfb, as I got from your tags, you can try this:

This is a self contained junit test that retrieves the authentication token and posts an apprequest. No user generated auth_token is required but you can only send apprequests like this to users that already have authorized your app.

Dependencies are JUnit, Commons HttpClient and restfb itself.

package com.apprequesttest;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpMethod;
import org.apache.commons.httpclient.methods.GetMethod;
import org.junit.Test;

import com.restfb.DefaultFacebookClient;
import com.restfb.Facebook;
import com.restfb.FacebookClient;
import com.restfb.Parameter;
import com.restfb.types.FacebookType;

public class AppRequestTest
{
    @Test
    public void testAppRequest() throws Exception
    {
        String appId = "YOUR_APP_ID";
        String appSecret = "YOUR_ACCESS_TOKEN";
        String tokenUrl = "https://graph.facebook.com/oauth/access_token?client_id=" + appId + "&client_secret=" + appSecret
                + "&grant_type=client_credentials";
        HttpClient client = new HttpClient();
        HttpMethod method = new GetMethod(tokenUrl);

        client.executeMethod(method);
        String rawAccessToken = new String(method.getResponseBody());

        String accessToken = rawAccessToken.split("=")[1];

        FacebookClient facebookClient = new DefaultFacebookClient(accessToken);

        String apprequestCall = "TARGET_USER_ID/apprequests";

        AppRequestResponse apprequest = facebookClient.publish(apprequestCall,
                                                               AppRequestResponse.class,
                                                               Parameter.with("message", "BANANAMSG"),
                                                               Parameter.with("data", "BANANADATA"));

        System.out.println(apprequest.request);
        System.out.println(apprequest.to);

    }

    /**
     * Couldn't find any beans that would acomodate this response on restfb so we create our own here
     * Looks like "to" is an array but this works well enough for the sake of the example 
     */
    public static class AppRequestResponse extends FacebookType
    {
        private static final long serialVersionUID = 1L;

        public AppRequestResponse()
        {
            // Empty
        }

        @Facebook
        public String request;

        @Facebook
        public String to;
    }
}

@garbelin...I tried your code and was able to send the invitation, but I have small problem. I keep getting this exception. I posted a question for the same http://stackoverflow.com/questions/10460014/facbook-post-userid-apprequest-throws-an-exception-invitation-is-sent-though — Santhosh, May 05 '12 at 08:17
@skokal01 I never got those empty 403 errors. To me it smells like a network issue. — garbelini, May 07 '12 at 09:57
Hi, I am getting 322391074505234 as request id and xxxx as to field. but I can't see the actual invitation when I check from the user account. what might be my missing point? — kitokid, May 29 '12 at 03:32
and I can't use the access token generated with the code above. if use, i hit 403 errors. So, I have to use access token that I have granted by user with the normal flow. — kitokid, May 29 '12 at 03:50
I can see 1 in Apps and Games. but can't see the app which send this invitation. Is there any settings that I need to set up my app. Actually my app is redirected to other url. not in facebookapps. — kitokid, May 29 '12 at 04:02
just my mistake, cause my app is web type. not the canvas type. when I set as canvas type, I can see all the invitations. Thanks. for the people who might face the situation like me, pls check this link.http://stackoverflow.com/questions/9185009/any-example-of-sending-apprequest-app-to-user — kitokid, May 29 '12 at 06:07
