I read this article.
So, I tried it and I put a number in the data property.
FB.ui({
method: 'apprequests',
message: 'Come join me and play at MyWebSite!',
data: '12345',
redirect_uri: 'myWebSite'
});
I get the request_ids, but how do I get the data part (the 12345 number)?.
on server side, you can do something like:(using php here)
$request_ids = $_GET['request_ids'];
$request_ids = explode(",", $request_ids);
foreach($request_ids as $request_id)
{
$request_object = $facebook->api($request_id);
if(isset($request_object['data'])) $req_data = $request_object['data']; //$req_data will be '12345' as per your request data set.
// after getting the data, you may like to delete the request.
$full_request_id = $request_id."_".$fbid; //$fbid is current user facebook id
$facebook->api("$full_request_id","DELETE");
}
Did you try Facebook's documentation too?
https://developers.facebook.com/docs/requests/ has more documentation; if a data parameter was added in the call to the requests dialog, the same value should also be there when requesting the Request details via the API (i.e. a call to /REQUEST_ID)
See the facebook developer site documentation for more details
http://developers.facebook.com/docs/reference/dialogs/requests/
Note:
data:Optional, additional data you may pass for tracking. This will be stored as part of the request objects created. The maximum length is 255 characters.

I am using Facebook realtime api, as I get only the updates and have to fetch the whole data by hitting the server again.
I have a page, my app added to that hence I am getting page feed(like, comment, post, all).
When any user posts on the page, we get the update from Facebook realtime update api. But when I try to fetch post data using the Koala gem it gives me error, note that error is not in case of Update from Page itself(page admin) but when some other user posts on it.
Following is the code for help :-
Trying to fetch using long lived page-token, and without that too, failing both ways
##graph = Koala::Facebook::API.new ACCESS_TOKENS["facebook"]["page_token"]
##public_graph = Koala::Facebook::API.new
JSON response from facebook :-
{"object"=>"page",
"entry"=>
[{"id"=>"123412341234234",
"time"=>1412341234,
"changes"=>
[{"field"=>"feed",
"value"=>
{"item"=>"post",
"verb"=>"add",
"post_id"=>123412341234123,
"sender_id"=>1234123412}}]}]}}
##public_graph.get_object("123412341234123")
*** Koala::Facebook::ClientError Exception: type: GraphMethodException, code: 100, message: Unsupported get request. [HTTP 400]
##graph.get_object("123412341234123")
*** Koala::Facebook::ClientError Exception: type: GraphMethodException, code: 100, message: Unsupported get request. [HTTP 400]
Please help me out to understand how to fetch the public post data using the post_id provided by the realtime-updates api of facebook.
Q: how to fetch the public post data using the post_id provided by the realtime-updates api of facebook.
For fetching public data of the post from the page, you will need to specify both the IDs (page id as well as post id) you are getting in the RT hit form fb.
You will need to pass id as <page_id>_<post_id>. In your case, it will be:
rt_hit = {"object"=>"page",
"entry"=>
[{"id"=>"123412341234234",
"time"=>1412341234,
"changes"=>
[{"field"=>"feed",
"value"=>
{"item"=>"post",
"verb"=>"add",
"post_id"=>123412341234123,
"sender_id"=>1234123412}}]}]}}
entry = rt_hit["entry"].first // you may want to have loop instead of `first`
public_id = "#{entry['id']}_#{entry['changes'].first['value']['post_id']}"
##public_graph.get_object(public_id) // fetch object
It is said, that it is not possible to initiate new conversation through the API alone, except using Facebook's own Form integrated in the app. Is this correct, or is there some new API, which enables me to initiate a new conversation?
To reply to an existing conversation, I retrieved the conversations id using the following FQL Query "SELECT thread_id, . WHERE viewer_id={0} AND folder_id=0". Afterwards I retrieved the PageAccessToken for my app page using my user Access token, and tried to use this call:
*You can reply to a user's message by issuing an HTTP POST to /CONVERSATION_ID/messages with the following parameters [conversation id, message]. A conversation ID look like t_id.216477638451347.*
My POST Call looked like this (this is not a valid thread id): /t_id.2319203912/messages with message parameter filled. But it always said "Unknown method". Can you help me out with this one? Is there a parameter missing? I passed in the page's Access Token to call this one.
Is there some API out (except Facebook's Chat API), that I am missing, which can send private messages to users?
Edit:
What I wonder about is, that the code below only returns a single page, the application's page. Is this correct, or is there another page token required? This is what bugged me the most about the returned page.
The FacebookClient uses my UserToken to perform the next following task.
This is the code to retrieve my Page Access Token:
dynamic pageService = FacebookContext.FacebookClient.GetTaskAsync("/"+UserId+"/accounts").Result;
dynamic pageResult = pageService.data[0];
_pageId = pageResult["id"].ToString();
return pageResult["access_token"].ToString();
Now the code to retrieve my ConversationÍd:
dynamic parameters = new ExpandoObject();
parameters.q = string.Format("SELECT thread_id, folder_id, subject, recipients, updated_time, parent_message_id, parent_thread_id, message_count, snippet, snippet_author, object_id, unread, viewer_id FROM thread WHERE viewer_id={0} AND folder_id=0", FacebookContext.UserId);
dynamic conversations = FacebookContext.FacebookClient.GetTaskAsync("/fql",parameters).Result;
The following code is executed using the access token retrieved from the code above (page access token request).
Now the Code used to send the reply:
dynamic parameters = new ExpandoObject();
parameters.message = CurrentAnswer;
string taskString = "/t_id." + _conversationId + "/messages";
dynamic result = FacebookContext.FacebookClient.PostTaskAsync(taskString,parameters).Result;
return true;
I also tried it with facebook's graph API Debugger using the token, which is returned by my first part of code. But with the same error message.
In the context of a given Facebook app, suppose User A invited user B to start using it. Once User B accepts to use the app, is there any way to retrieve the ID of User A programmatically (via either PHP/JS SDK) ? This doesn't seem quite documented.
For what it's worth, A/B users are friends, if it's any use.
when user comes following the app request, you can get request id's using
$_GET['request_ids']
then retrieve all the request ids with which you can call graph api to get the corresponding request details like below:
if(isset($_GET['request_ids']))
{
$request_ids = $_GET['request_ids'];
}
$request_ids = explode(",", $request_ids);
foreach($request_ids as $request_id)
{
$request_object = $facebook->api($request_id);
//this $request_object have sender facebook id in the field uid_from
}
If you look here:
http://developers.facebook.com/docs/reference/dialogs/requests/
You can see the object layout. Of note is the data property:
Optional, additional data you may pass for tracking. This will be
stored as part of the request objects created. The maximum length is
255 characters.
In this object you can add your referring UserId and then when the request is claimed, you can then process it on your end.
Hope this helps.
It used to be that the response from a request gave us an array of request ids (as described here http://developers.facebook.com/docs/reference/dialogs/requests/) but it seems now the response variable returns two items insead 'to' and 'request'. To being a comma delimited string of user ids and request being a request id. Is this correct? I have seen nothing about this anywhere but it is the behavior I am seeing currently.
Update
Here is a super simplified version of my call:
FB.ui({method: 'apprequests', message: 'My Great Request'}, requestCallback);
function requestCallback(response) {
for(var key in response){
console.log(key);
console.log(response[key]);
}
}
When I make a request to one person the variable response has two keys: request and to. Request is a request id, to is the id of the person I'm sending the request to. If I make a call to the graph api using the provided request id, however, I find that the user under both 'to' and 'from' are equal to the sender's name and fbid.
Alternatively, if I request to multiple people request is equal to a single request id and to is an array containing all the fbids of the users that had requests sent to them. When I make a call to the graph api, however, I once more find that both 'to' and 'from' contain the user id and name of the requesting user.
I faced similar issue yesterday. Had to fix my code. But today request_ids were back in the response. So I updated the code again. But this time to work with both type of objects.
I found the documentation here (move down to the "Performance improvements" section)
http://developers.facebook.com/blog/post/569/
But it still doesn't explains why they reverted the change today. Or was it accidently released yesterday.
As in the documentation, the new callback will receive an object (response) that contains an array (request_ids) of request ids:
{
"request_ids": [
0: [request_id]
1: [request_id]
...
]
}
So I suppose you can loop using this modified code:
function requestCallback(response) {
for( var k in response.request_ids ) {
console.log(k);
console.log(response.request_ids[k]);
}
}
There is already a bug filed here
http://developers.facebook.com/bugs/129565473812085
There is no clear information yet whether the response is really changed or its a bug.
I am trying to submit a batch request to add objects via Open Graph Beta to a user's Timeline but no matter what I do I get this:
The action you're trying to publish is invalid because it does not specify any reference objects. At least one of the following properties must be specified: egg.
I am specifying an egg property though. My requests look like this:
https://graph.facebook.com/?batch=[{'method':'POST','relative_url':'/me/my_namespace:find','egg':'http%3A%2F%2Fwww.mydomain.com%2Fmy_namespace%2Fog%2Fegg.php%3Ftypeid%3D-966','start_time':'1317439270','end_time':'1317439270'}]&access_token=<<snipped>>&method=post
I am sending egg as a url-encoded reference string to a URL that contains my open graph data -- the URL does work if I send it not as a batch but since when setting up a user's Timeline I will in some cases have to post up to 1000 actions I am trying to speed things up by batching them.
I was able to successfully delete via a batch request.
Instead of sending the 'egg' as a param of the batch object, you need to format this like a query string and send it in the body param.
Also, relative_url should not begin with a '/'
Try posting this instead...
https://graph.facebook.com/batch?access_token=TOKEN&method=post&batch=
[
{
"method": "post",
"relative_uri": "me/your_namespace:find",
"body": "egg=http%3A%2F%2Fwww.mydomain.com%2Fmy_namespace%2Fog%2Fegg.php%3Ftypeid%3D-966&start_time= 1317439270&end_time= 1317439270
}
]
I've tested this and it works.
When Posting data to the batch API, the data must be formatted like a querysting and sent in the 'body' param as a string.
