I want to delete the post as page.
I already have access token of the admin user and access token from the page.
My Code:
var fbClient = new FacebookClient { AccessToken = getPageAccessToken() };
dynamic parameters = new ExpandoObject();
parameters.id = postId;
fbClient.Delete(m_GroupId + "/feed",parameters);
I get the following error:
{"error":
{
"type":"OAuthException",
"message":"Invalid token: \"PAGE_ID\". An ID has already been specified."
}
}
I replaced the page id above with PAGE_ID
use the page access token and pass the post id as the path for Delete method.
var fb = new FacebookClient("pageAccessToken");
fb.Delete(postId);
I don't know the C# SDK, but from the look of it you're setting the ID twice, once with parameters.id and again with m_GroupID

question
What problem in my url?
All param is getted facebook dev (my app).
I know maybe its too late but I just wanted to comment. If you still having this issue, make sure that you have same FacebookCallBack method name everywhere. I mean, for instance I have an External Login function which returns ;
https://www.facebook.com/dialog/oauth?client_id=" + FB_APP_ID + "&redirect_uri=" + System.Net.WebUtility.UrlEncode(pageUrl + "account/**FacebookLoginCallback**?returnUrl=%2F").Replace("%3F", "&") + "&scope=email&enforce_https=1
and also I have a FacebookLoginCallback method which has exactly the same name with I have above. ("account/FacebookLoginCallback?....")
[HttpGet("**FacebookLoginCallback**")]
public async Task<IActionResult> **FacebookLoginCallback**(string code, string returnUrl)
{
try
{
var myUrl = new Uri(HttpContext.Request.GetDisplayUrl()).GetLeftPart(UriPartial.Authority);
var pageUrl = new UriBuilder(myUrl);
var result = (IDictionary<string, object>)fb.Get("oauth/access_token", new
{
client_id = FB_APP_ID,
client_secret = FB_APP_SECRET,
redirect_uri = pageUrl.Uri.AbsoluteUri.TrimEnd('/') + Url.Action("**FacebookLoginCallback**", "Account", new { returnUrl = returnUrl }),
code = code
});
}
......
}
Please double check your variable/function names if you have those in your url.
Happy Coding
First, both redirect_uri paramaters to authorize and access_token must match.
I have a problem when trying to post on my own business time line on facebook.
I get an error that says:
"(OAuthException)(#200) The user hasn't authorized the application to perform this action"
I think this has to do with the scope "publish_actions" in somehow but how can I authorize this publish_actions permission exactly?
I have looked everywhere in my account under "https://developers.facebook.com"
I have put my App for review but I cant add "publish_actions" as a permission for Facebook to review because on this permission there is a message which says: "It looks like you haven't made any API requests to access content with the publish_actions permission in the last 30 days"
But how can I use this permission without having the permission??
I would be very greatful for help if I am on the right track and what I am missing out?
Thank you!
try
{
String appID = "12345";
String appSecret = "123456";
String accessToken = "123|1234_a-b";
String clientToken = "1234567";
String pageID = "123456789";
Facebook.FacebookClient client = new Facebook.FacebookClient(accessToken);
var dicParams = new Dictionary<string, object>();
dicParams["message"] = "Hello on the time line message!";

dicParams["access_token"] = accessToken;
var publishResponse = client.Post("/" + pageID + "/feed", dicParams);
MessageBox.Show("You posted on the timeline successfully!");
}
catch (Exception ex)
{ MessageBox.Show(ex.ToString()); }
Attempt 2:
I was looking at the facebook documentation and found an URL which seems relevant to post a message on the business page timeline:
POST graph.facebook.com/{user-id}/feed?message={message}&access_token={access-token}
I have tried to put it down in code like below but again, I receive the same error message:
(OAuthException)(#200) The user hasn't authorized the application to perform this action
Question is what I do wrong. Do I need to get any other access token with "publish_action" permission?. If that is the case I can't figure out how to get such token?
String appID = "12345";
String appSecret = "123456";
String accessToken = "123|1234_a-b";
String clientToken = "1234567";
String pageID = "123456789";
String message = "Hello World";
String requestUrl = "https://graph.facebook.com/" + pageID + "/feed?message=" + message + "&access_token=" + accessToken;
RestSharp.RestClient rc = new RestSharp.RestClient();
RestSharp.RestRequest request = new RestSharp.RestRequest(requestUrl, RestSharp.Method.POST);
request.AddHeader("Content-Type", "application/json");
request.AddHeader("x-li-format", "json");
request.RequestFormat = RestSharp.DataFormat.Json;
RestSharp.RestResponse restResponse = (RestSharp.RestResponse)rc.Execute(request);
RestSharp.ResponseStatus responseStatus = restResponse.ResponseStatus;
//"(OAuthException)(#200) The user hasn't authorized the application to perform this action"
MessageBox.Show(restResponse.Content.ToString());
I have found a solution which works. This code do post a "Message" to the timeline.
Question This code works for my business page. I also like to post on my personal page for friends. So tried to change the pageID to the the ID which is my personal page: (pageID = "987654321") but still it posts on my business page.
I wonder if I need to get a page token specifically for the personal page as well?
If that is the case, I wonder how this token can be achieved?
/*********************************************************************************************************************************************************************/
//STEPS!!! to get a non-expiring page access token:
//1. access the following URL and note the returned access token within the browser's address bar:
//https://www.facebook.com/dialog/oauth?client_id=APP_ID&redirect_uri=REDIRECT_URI&scope=manage_pages,publish_actions&response_type=token
//2. access the following URL and within the returned data find the desired page's name and note the access token:

I am using https://github.com/sanjeevdwivedi/facebook-csharp-sdk to integrate facebook in my wp8 app.
I want to know how to access the user email id using facebook-csharp-sdk below is the code I am using
FacebookSession session = FacebookSessionClient.LoginAsync("user_about_me,read_stream");
FacebookClient _fb = new FacebookClient(session.AccessToken);
dynamic parameters = new ExpandoObject();
parameters.access_token = session.AccessToken;
parameters.fields = "email,first_name,last_name";
dynamic result = await _fb.GetTaskAsync("me", parameters);
But I am getting only firstname , lastname and id of the logged in result field. Please suggest where am i missing?
You should ask for the email permission.
FacebookSession session = FacebookSessionClient.LoginAsync("user_about_me,read_stream,email");
The last item in the LoginAsync params I placed is email
See permissions for more info
I have registered an app in facebook developers program and I can retrieve posts from facebook page using fb api, but I cannot retrieve posts from facebook profile. Should I use some different access token for both page or profile? Is there a different way for retrieving posts from facebook page and profile?
Any help will be appreciated!
You may need the user_status permission.
And you call the posts using this graph query {USER_ID}?fields=statuses
Prerequisite:- You need to have valida FB token for all the request:-
I am answering using c# language.
Step 1:- First you need to get the user's FB id using FB token
I am using Facebook SDK 7.0.6 for querying purpose
here's how to initialize the FB service which we will use in our consecutive calls.
FacebookService facebookService = new FacebookService(facebookToken);
var _facebookClient = new Facebook.FacebookClient(token);
Code snippet
public string GetFacebookID(string facebookToken)
{
dynamic result = _facebookClient.Get("me?fields=id");
if (result.ToString().Contains("id"))
{
return result["id"];
}
return string.Empty;
}
after that you can execute below method to get user's post using FB ID and token
public List<Post> GetPostsForUser(string facebookID)
{
List<Post> posts = new List<Post>();
dynamic result = _facebookClient.Get(facebookID + "/posts"); //Case Sensitive, Posts doesn´t work
if (result.ToString().Contains("data") && result.data.Count > 0)
{
foreach (var item in result.data)
{
posts.Add(new Post
{
ID = item.id,
Story = item.story,
Message = item.message,
Created_Time = Convert.ToDateTime(item.created_time),
Reactions = GetReactions(item.id)
});
}
result = _facebookClient.Get(GetNextURL(result.ToString()));
}
return posts;
}
I need to know if it's possible to make it so authorized users can upload photos to a fan page of a company (to the wall) using the graph API.
Also, is it possible to become like (become a fan) of a company page through the api once the user is authorized.
Yes you can. You need to obtain your admin access token by using the Graph API explorer (https://developers.facebook.com/tools/explorer) and with a call to
https://graph.facebook.com/{adminfacebookid}/accounts
this will list all pages and apps your admin has access to. Look for the fan page in question and copy the accessToken.
Next get the albumid by clicking on the id of the page, then adding /albums to the request
armed with this you can then post the image data to the url, using the facebook web client
like this
protected void PublishToPublicGallery(string accessToken, string filename, long albumId, string imagename)
{
var facebookClient = new FacebookClient(accessToken);
var mediaObject = new FacebookMediaObject
{
FileName = filename,
ContentType = "image/jpeg"
};
var fileBytes = System.IO.File.ReadAllBytes(filename);
mediaObject.SetValue(fileBytes);
IDictionary<string, object> upload = new Dictionary<string, object>();
upload.Add("name", imagename);
upload.Add("source", mediaObject);
var result = facebookClient.Post("/" + albumId + "/photos", upload) as JsonObject;
}
