I am developing an app which requires data from social networks..I wanted to know how to fetch details of a person from his fid in Facebook.I want to fetch only the data are marked public.From google search i got to know that we can use rest API or java API to get the data but it requires API key or access token which are generated only after logging in to the Facebook. please explain me if there is any other way to fetch the details.

Rest API is deprecated, and such a thing as a “Java API” does not exist – it’s just the Graph API that you’ll mainly use to get information from Facebook, and it’s quite well documented.
but it requires API key or access token which are generated only after logging in to the Facebook.
Of course you will need an app to be able to talk to the Graph API – but it does not require a user to login/“connect” to your app just to read basic (public) profile info. An app access token will be enough for that.

I am new to smart sheet. I need to use smart sheet API inside an Node Application to get sheets which are being uploaded by a user. I have gone through the documentation of smart sheet API. Document says to call API first need to get auth code which requires client_id. After getting auth code, need to get token.
I am not sure if I need to contact that user to get client Id or need to create new account. What should be my next step.
Having others use your application to get their data would require you to have them login to your app using their Smartsheet credentials. Then as the requests are made they can be done as that user. This is can be done by implementing the Smartsheet OAuth flow. There is more information on this in the Third-party App Development section of our API docs.
If you are using Node.js you can see a simple implementation of using our SDK on Github here.
As for the OAuth flow there is also an example of implementing that in Node.js on the Smartsheet Samples Github.
Using app access token had previously been asked in this question (How to use Facebook appAccessToken with Spring Social) and Craig Walls gave a good explanation why the spring-social API should be user-based for most cases.
I have a scenario, however where I would like our server-side application to make a couple of queries that should not require user-specific permissions. I picked a random public page for examples below
I would like to:
View details about a public page by alias/id
https://graph.facebook.com/v2.0/121727254549188
https://graph.facebook.com/v2.0/peterstevensmotorcycles

Search for pages
https://graph.facebook.com/v2.0/search?q=Peter%20Stevens%20Motorcycles&type=page
When I test these in the Graph API explorer (https://developers.facebook.com/tools/explorer) using an App Access Token they work fine. App Access Token is obtained by hitting https://graph.facebook.com/v2.0/oauth/access_token?client_id={app-id}&client_secret={app-secret}&grant_type=client_credentials and replacing client_id and client_secret with my Facebook client credentials.
Our application would like to have the ability to make these for any given name so we can make queries about a company's presence.
We will have similar requirements for Twitter, LinkedIn and others so I just wanted to check if there are any means to do this in the current API or whether it will not suit our requirements.
You do not need to fetch an app access token - you can actually use the app id and secret separated by "|" as the access token. - You can see it at the bottom of the app access token section in the documentation: https://developers.facebook.com/docs/facebook-login/access-tokens#apptokens
Spring Social's Facebook API binding does not (yet) support v2.0, but that's something I'm working on right now...so hopefully soon. Once that's complete, there'll certainly be some operations that work only with user access tokens and some that only work with app access tokens, and some that will work with either (FWIW, Twitter's API has a similar set of circumstances).
Keep an eye on the project in GitHub or follow #SpringSocial on Twitter to know when the v2.0 stuff is available. (I'd appreciate any help I can get in testing it.)
Although it makes no sense at all to obtain your FacebookTemplate via the connection framework for app token requests (connections are, by nature, a user-oriented concept), you can always construct a FacebookTemplate wherever you need it, giving it an app access token obtained via OAuth2Template's authenticateClient(). You can certainly do that now with the v1.0 API binding, but I'm uncertain what ops an app token would work with.
FWIW, as I'm working on the v2.0 API binding, I'm starting to sense an opportunity for FacebookTemplate to carry two tokens: A user token and an app token. This way you can perform app-centric requests even from a FacebookTemplate obtained from the connection framework. Then the only time you'd ever want to construct a FacebookTemplate manually is if there are some operations for which either kind of token will work, but the results would be different depending on what type of token is used.
For this task I have already created my own facebook application to get the API key and secret key. Can anyone explain the next steps that should be done to
1) Read from facebook API
2) Write my own database
by using web services
Thanks in advance!
A high level answer:
I'm assuming you want to use the authorization code OAuth flow (this means you want Facebook users to give you access to their profiles so you can grab data from there). If so, you need to bring up a web server and an application that will run your users through the Facebook OAuth flow. In case you just want to access Facebook with your own credentials you don't have to have a web server, simply use the client credentials OAuth flow.
So, Once you have a valid access token, you simply make calls to Facebook API using this token. using Facebook Graph API is simply a matter of calling URLs and getting the data as JSON.
You can test-drive the API here.
BTW, according to Facebook's platform policy, you're only allowed to store Facebook data for caching purposes.
Let me know if this helps.
I want to know the best way how to obtain the basic info of a foursquare location, so for instance the mayor, total checkins, profile picture,...
Important: I should be able to get this information without providing an oauth_token, and that exactly is my problem. The API demands a token, but I figured it should be possible to get the data without the token, because you can access places without authenticating.
E.g.: https://foursquare.com/v/whole-foods/49bc3b0af964a52020541fe3
The reason I want to do this, is because I want to make a facebook application which fetches the data for a locationbased facebook page and I don't want to demand the facebook users to login to foursquare first.
An alternative is webscraping, but that really is my last option.
Thanks in advance for your responses.
The "Venues Platform" allows you to access venue information through the API without an OAuth token. You can access all the information you're looking for, all you need to do is supply your Client ID and Client Secret when making a request to the /venues API endpoint.
On the documentation page for Facebook Graph API there are a lot of example links such as https://graph.facebook.com/me/likes?access_token=SOME_AT
Could anyone explain how the access_token for these links are generated?
All I've read in the documentation were about getting access_token only for applications, but on that page everyone could get an access_token without one.
You can use the graph API to get public information. People set privacy settings on facebook, so to prevent social freaks from stalking you, they(fb) created Autorisation.What I believe is that on the documentation, they are generating the access token using the Developers App. You can generate this Access token by making an application and asking a user to Authorise your application to access his data using OAUTH dialogs. Usually people reading at developer.facebook.com have enabled the Developers app so it easily opens your information.
The Graph API as such allows you to
easily access all public information
about an object. For example,
https://graph.facebook.com/btaylor
(Bret Taylor) returns all the public
information about Bret. For example a
user's first name, last name and
profile picture are publicly
available.
To get additional information about a
user, you must first get their
permission. At a high level, you need
to get an access token for the
Facebook user. After you obtain the
access token for the user, you can
perform authorized requests on behalf
of that user by including the access
token in your Graph API requests:
The access_token in these links are generated using your Facebook identity and an application ID (presumable associated to "developers.facebook.com"). If you go to the same page with another Facebook account, you will see different access tokens.
