I am retrieving the messaging inbox with the following graph api call:
https://graph.facebook.com/me/inbox?access_token=...
It returns an array of messages that each have an identifying "id" (same as message id as returned by FQL)
I would like to be able to provide a link for the user to view a message directly on Facebook.com.
Something like: https://www.facebook.com/messages/?action=read&tid=....
That is the link you get to if you you browse to a message from facebook itself.
However I can't seem to find a way to discover the correct tid from either the Graph API or FQL.
I haven't had any luck in figuring out an alternative URL either.
This url used to work, but is broken for me now: http://facebook.com/?sk=messages&tid=...
It just redirects to the top level messaging page: https://www.facebook.com/messages/
ANY IDEAS?
Thanks so much
From graph API get to me/inbox the result set gives id as part of each object returned. This is also thread_id.
If the id you have is a string object (probably a guid), this is from Facebook's older message system storage structure. Now they've updated to a new storage structure that requires the old ones to be migrated into the new
So you have a fairly easy check:
If thread id is a long (Int64/BigInt), then you have a new thread and can use
http://www.facebook.com/messages/?action=read&tid=id.THREAD_ID
If thread id is a string then you have a older thread and can use
http://www.facebook.com/messages/?action=read&tid=THREAD_ID
many programming languages have their own form of checking the type of a value.
var threadId = (string)data.thread_id;
var longVal = 0L;
var isLong = Int64.TryParse(threadId, out longVal);
var threadUrl = (isLong) ?
"http://www.facebook.com/messages/?action=read&tid=id." + threadId :
"http://www.facebook.com/messages/?action=read&tid=" + threadId;

I'm trying fetch list of post from given set of facebook pages using restfb(java)
List fbPages = Arrays.asList("178697151159/posts", "538560813021153/posts");
JsonObject fetchObjectsSubResults = client.fetchObjects(fbPages, JsonObject.class, Parameter.with("fields","shares,created_time"),Parameter.with("limit", 5));
But I'm getting a runtime error from facebook api as following.. IS there any body that can help me out to resolve this or is this impossible (
Exception in thread "main" com.restfb.exception.FacebookOAuthException: Received Facebook error response of type OAuthException: (#803) Some of the aliases you requested do not exist: 178697151159/posts?,538560813021153/posts? (code 803, subcode null)

I suggest using 1 call per page. SO it should look like:
Connection<Post> postConnection = client.fetchConnection(pageId+ "/posts", Post.class, Parameter.with("fields","shares,created_time"), Parameter.with("limit","5"));
Depending on your use case, you can run over the postConnection with a for loop to get all posts or take the data from the first page of the result set with postConnection.getData().
In both cases you can eventually work with a Post type and access the fields your are interested in. The other fields are left null.
BTW working with multiple ids in a single call or request these ids one after another makes no difference to the Facebook calls. The amount that is internally calculated is the same; in your case 2.
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.
Does anyone have a definitive way to post to a user's wall, using nothing but the .NET Framework, or Silverlight?
Problems deriving from people's attempts have been asked here on SO, but I cannot find a full, clear explanation of the Graph API spec and a simple example using WebClient or some similar class from System.Net.
Do I have to send all feed item properties as parameters in the query string? Can I construct a JSON object to represent the feed item and send that (with the access token as the only parameter)?
I expect its no more than a 5 line code snippet, else, point me at the spec in the FB docs.
Thanks for your help,
Luke
This is taken from how we post to a user's wall. We place the data for the post in the request body (I think we found this to be more reliable than including all the parameters in the query part of the request), it has the same format as a URL encoded query string.
I agree that the documentation is rather poor at explaining how to interact with a lot of resources. Typically I look at the documentation for information on fields and connections, then work with the Graph API Explorer to understand how the request needs to be constructed. Once I've got that down it's pretty easy to implement in C# or whatever. The only SDK I use is Facebook's Javascript SDK. I've found the others (especially 3rd party) are more complicated, buggy, or broken than rolling my own.
private void PostStatus (string accessToken, string userId)
{
UriBuilder address = new UriBuilder ();
address.Scheme = "https";
address.Host = "graph.facebook.com";
address.Path = userId + "/feed";
address.Query = "access_token=" + accessToken;
StringBuilder data = new StringBuilder ();
data.Append ("caption=" + HttpUtility.UrlEncodeUnicode ("Set by app to describe the app."));
data.Append ("&link=" + HttpUtility.UrlEncodeUnicode ("http://example.com/some_resource_to_go_to_when_clicked"));
data.Append ("&description=" + HttpUtility.UrlEncodeUnicode ("Message set by user."));
data.Append ("&name=" + HttpUtility.UrlEncodeUnicode ("App. name"));
data.Append ("&picture=" + HttpUtility.UrlEncodeUnicode ("http://example.com/image.jpg"));
WebClient client = new WebClient ();
string response = client.UploadString (address.ToString (), data.ToString ());
}
I don't know much about .net or silverlight, but the facebook api works with simple http requests.
All the different sdks (with the exception of the javascript one) are mainly just wrappers for the http requests with the "feature" of adding the access token to all requests.
Not in all requests the parameters are sent as querystring, in some POST requests you need to send them in the request body (application/x-www-form-urlencoded), and you can not send the data as json.
If the C# sdk is not to your liking, you can simply create one for your exact needs.
As I wrote, you just need to wrap the requests, and you can of course have a method that will get a json as parameter and will break it to the different parameters to be sent along with the request.
I would point you to the facebook documentation but you haven't asked anything specific so there's nothing to point you to except for the landing page.
There is How can I construct a link to view a message on facebook.com if I have the message id question, but it is unanswered. What if I got the id of the thread using /me/inbox API endpoint and need to redirect user to the Facebook itself showing this thread? How do I construct the URL. There seem to be URLs like http://www.facebook.com/messages/?action=read&tid=id.143666952390138 where thread id is the number in the end. But there are also some stranger URLs like http://www.facebook.com/messages/?action=read&tid=27726d81656e4c07ae5654116cccb724 where the previous rule doesn't work.
Is there any solution to getting thread URL using Graph API or FQL?
