I want to write a script on Google Apps Script which can access my Facebook friends list and sync the photo and other data with my Google contacts details.
I am trying to use FQL - but perhaps there is a better way. I have tried to read up a bit but can't really find where to begin - will I be able to access this via FQL or will I also need to write a Facebook application for this?
Has anyone attempted something similar or have any tips?
Edit: Ok, so I am trying to use a facebook app to access the data - but I can't even get it to return an access token.
Any ideas?
var url = "https://www.facebook.com/dialog/oauth?client_id={app_id}&redirect_uri=https://www.facebook.com/connect/login_success.html";
var response = UrlFetchApp.fetch(url);
var ret = response.getContentText();
Also, how can the token be stored in Google Apps Scripts? Would I need to create a new document and save the ID in that? It seems a bit messy..
For storing the token, I believe you can use the ScriptProperties facility:
Store:
ScriptProperties.setProperty("token", <your token goes here>);
Retrieve:
var token = ScriptProperties.getProperty("token");

So I am building a restaurant app and one of the features I want is to allow a user of the app to see photos from a particular restaurant's Instagram account.
And I want a user to be able to see this without having to login to their Instagram account, so they shouldn't even need an Instagram account for this to work.
So I have read this answer How can I get a user's media from Instagram without authenticating as a user?
And I tried what it said and used the client_id(which I recieved when I registered my app using my personal Instagram account), but I still get an error back saying :
{
meta: {
error_type: "OAuthAccessTokenException",
code: 400,
error_message: "The access_token provided is invalid."
}
}
The endpoint I am trying to hit is :
https://api.instagram.com/v1/users/search?q=[USERNAME]&client_id=[CLIENT ID]
So do I absolutely need an access token for this to work(and thus have to enforce a user to log in) ?
If I do, then is there way to generate an access token somehow without forcing the user log in?
I believe there is a way around this, as the popular dating app Tinder has this desired functionality I am looking for, as it allows you to see photos from people's Instagram account without having to log in! (I have just verified this 5 minutes ago!)
Any help on this would be much appreciated.
Thanks.
Edit April 2018: After facebook privacy case this endpoint is immediately put out of service. It seems we need to parse the JSON embedded in <script> tag directly within the profile page:
<script type="text/javascript">window._sharedData = {"activity_counts":...
Any better ideas are welcome.
You can use the most recent link
GET https://www.instagram.com/{username}/?__a=1
to get latest 20 posts in JSON format. Hope you put this to good use.
edit: other ways aren't valid anymore:
https://www.instagram.com/{username}/media/
Instagram used to allow most API requests with just client_id and without access_token, the apps registered back in the day still work with way, thats how some apps are able to show instagram photos without user login.
Instagram has changes the API specification, so new apps will have to get access_token, older apps will have to change before June 2016.
One way you can work around this is by using access_token generated by your account to access photos. Login locally and get access_token, use this for all API calls, it should not change, unless u change password,if it expires, regenerate and update in your server.
Since the endpoints don't exist anymore I switched to a PHP library -
https://github.com/pgrimaud/instagram-user-feed
Installed this lib with composer:
composer require pgrimaud/instagram-user-feed "^4.0"
To get a feed object -
$cache = new Instagram\Storage\CacheManager();
$api = new Instagram\Api($cache);
$api->setUserName('myvetbox');
$feed = $api->getFeed();
Example of how to use that object -
foreach ($feed->medias as $key => $value) {
echo '<li><img src="'.$value->thumbnailSrc.'"></li>';
}
I am writing a Azure Service that will occasionally write to my facebook page as a status. Since the service does not have a UI component, a majority of the examples on the Facebook and Facebook .NET SDK pages are not helpful.
I created an application on facebook and then fired up the F# REPL in Visual Studio. I generated the token like so:
#r "../packages/Facebook.7.0.6/lib/net45/Facebook.dll"
#r "../packages/Newtonsoft.Json.7.0.1/lib/net45/Newtonsoft.Json.dll"
open Facebook
open Newtonsoft.Json
type Credentials = {client_id:string; client_secret:string; grant_type:string;scope:string}
let credentials = {client_id="859968674039398";
client_secret="XXXXXXXXXX";
grant_type="client_credentials";
scope="manage_pages,publish_stream,read_stream,publish_checkins,offline_access"}
let client = FacebookClient()
let tokenJson = client.Get("oauth/access_token",credentials)
type Token = {access_token:string}
let token = JsonConvert.DeserializeObject<Token>(tokenJson.ToString())
A token comes back as expected. However, when I go to use the token, I am getting errors:
let client' = FacebookClient(token.access_token)
let me = client'.Get("me")
returns
An active access token must be used to query information about the
current user.
and
let pageId = "/me"
type FacecbookPost = {title:string; message:string}
let post = {title="Test Title"; message = "Test Message"}
let postResponse = client'.Post(pageId + "/feed", post)
returns
The user hasn't authorized the application to perform this action
When I read the docs, they talk about getting the application to be approved by Facebook -> but that makes no sense in my use case b/c there is no application as defined with a human end user -> or even any other user invoking the code.
When I generate the token on Facebook Graph Api explorer with the correct permissions, I can use the token to make those GETS and POSTS. Should I just generate the token and stick it in my .config file? How long does a token last?
Thanks in advance
I think you haven't fully understood how Facebook API works.
You always need an App to perform an action (in your case the APP is 859968674039398)
In order to post on behalf a user, you will need that user to grant permissions to your App.
Your App has to be public and if you require more permissions than the basic ones, you need to go through the review process.
The access token you get from the Graph API Explorer (which is an App BTW) is only for you.
Please read the docs CBro provided.
I hope it helps.
I'm a newbie to app development. I am building a Windows Phone 8.1 app and have followed the tutorial here: http://azure.microsoft.com/en-us/documentation/articles/app-service-mobile-dotnet-backend-windows-store-dotnet-get-started-users-preview/ to add authentication using Facebook. Everything seems to work fine, except that every now and again it appears to stop bringing back any data from my Azure database. Further investigation revealed that the UserId that is being shown from the code below, changes periodically (although I can't quite work out how often it changes).
// Define a member variable for storing the signed-in user.
private MobileServiceUser user;
...
var provider = "Facebook";
...
// Login with the identity provider.
user = await App.MobileService.LoginAsync(provider);
// Create and store the user credentials.
credential = new PasswordCredential(provider,
user.UserId, user.MobileServiceAuthenticationToken);
vault.Add(credential);
...
message = string.Format("You are now logged in - {0}", user.UserId);
var dialog = new MessageDialog(message);
dialog.Commands.Add(new UICommand("OK"));
await dialog.ShowAsync();
This code is identical to the code in the tutorial. The Facebook app settings (on the Facebook developers site) confirm that I am using v2.3 of their API so I should be getting app-scoped UserIds back. I have only ever logged in with one Facebook account, so I would expect the UserId to be the same each time, but they're not. The UserId is prefaced with 'sid:', which someone on the Facebook developers group on Facebook itself says stands for Session ID, which they would expect to change, but if that's the case, I can't work out where to get the actual UserId from that I can then store in my database and do useful things with. I'm sure I must be doing something basic wrong, but I have spent hours Googling this and cannot (unusually) find an answer.
Any help would be greatly appreciated.
Thanks!
So dug deeper. This is how Mobile Apps work (I was thinking from a Mobile Services perspective). The issue here is that the Gateway doesn't provide static SIDs, which is what User.userId provides. The work around to this is listed in the migration doc.
You can only get the Facebook AppId on the server.
ServiceUser user = (ServiceUser) this.User;
FacebookCredentials creds = (await user.GetIdentitiesAsync()).OfType< FacebookCredentials >().FirstOrDefault();
string mobileServicesUserId = creds.Provider + ":" + creds.UserId;
You should note, that this Id is directly connected with your Facebook App registration. If you ever want to migrate your App to a new Facebook App, you'd have to migrate them. You can also use the Facebook AppId to look up the user's global facebook Id via the Facebook Graph API, which you could use between applications. If you don't see yourself using multiple apps, etc., you can use the Facebook AppId just fine.
Hard to tell what's going on to cause you to use a SID instead of the Faceboook token (which like Facebook:10153...).
It may be faster to rip out the code and reimplement the Auth GetStarted. Maybe you missed a step or misconfigured something along the way. If you have the code hosted on github, I can try to take a look.
Another thing you can do is to not trust the user to give you their User id when you save it to a table. On your insert function, you can add it there.
function insert(item, user, request) {
item.id = user.userId;
request.execute();
}
That should, theoretically, be a valid Facebook token. Let me know if that doesn't work; can dig deeper.
I am building a website app in MVC5 that allows a user to login using Facebook/Twitter. Once they are logged in we will look through their photos for ones marked with a certain hashtag.
I have the login working for both FB and Twitter - and using Linq2Twitter I can get the and post photos.
However with Facebook I am having some problems. My understanding with Facebook is that after the login I have to make a second call to https://graph.facebook.com/oauth/access_token in order to get a short lived access token.
However this call requires a "code" and a returnUri. I am unsure what this code is or how to get it, and what return URI to use.
My startup.Auth.cs looks like this
var facebookOptions = new FacebookAuthenticationOptions();
facebookOptions.Scope.Add("user_photos");
facebookOptions.AppId = ConfigurationManager.AppSettings["facebookAppId"];
facebookOptions.AppSecret = ConfigurationManager.AppSettings["facebookAppSecret"];
app.UseFacebookAuthentication(facebookOptions);
And everything logs in fine and I end back at ExternalLoginCallback
So where do I go from here. How do I find this code and what returnUri do I use in order to get the access code.
Once I have this access code I plan to call (https://developers.facebook.com/docs/graph-api/reference/v2.1/user/photos)
Hopefully I am going about this the correct way and my question makes sense
Many thanks.
Okay - This solves my problem
http://blogs.msdn.com/b/webdev/archive/2013/10/16/get-more-information-from-social-providers-used-in-the-vs-2013-project-templates.aspx
I want to create a flash Facebook application in which, after pressing a button, the user will be able to browse his/her photo albums and choose a photo. How should i do that? What will be the code under the button to gain authentication from any user using this application?
Thanks.
I am currently writing a facebook application for a university assignment that will allow the user to do everything you can do in facebook, but via the flash player window. You will need a few basic things happening in order to do it.
User log in and authentication - this must be done via Facebook - using OAuth authentication, and meeting all of facebook's security policies
register the application with facebook
Use the Graph API (facebook's developer's toolkit) to get the necessary functions that will communicate with facebook via flash.
In Flash itself you will use a bunch of URLRequest functions to send out to FB for information, then you will need to retrieve that data responses and store them to variables (extracting data with a few lines of code is easy, something like this;
//initialise variables
public var photoURL:String;
var Request:URLRequest = new URLRequest("http://www.whatever the url for the graph api service you are using which is founf from FB");
//that ^^ will send off a request for the url, you then want to use the returned data by registering an event handler like this below
functionName.addEventListener(onComplete, completeHandler);
functionName(event, EVENT)
{
var loader:URLLoader = new URLLoader(Request);
var data:XML = new XMLData(load.loader); //i think this is right but not 100% sure, fiddle with it
//then you want to extract the data that is returned, for example, extracting xml data from a rest request works by hitting data from the xml by specifying a path to the object you want. an example of xml is this <rsp stat="ok"><photos ......more code="morecode"><photo url="url of photo"></photo</photos> so you can hit the url in that example like this;
photoURL = data.photos.photo.#url; //this line will grab the photo url for you, allowing you to dynamically create an array and assign photos to the flash stage according to the url you get
}
this is fairly advanced stuff and I am assuming that you have some decent knowledge on AS3, XML, and the FB API, if you need more help just reply
