Facebook authentication using Oauth 2.0 - facebook

I want to access facebook REST API's using PHP OAUTH functions instead using their php_sdk. Is there anyone to help me out in this?

You can save the user details in a table as mentioned in http://net.tutsplus.com/tutorials/php/how-to-authenticate-your-users-with-facebook-connect/ and manage sessions from that point effectively to achieve your goal

Integrating Social Login with Instagram basic display api

While reading instagram basic display api documentation I get the sense that we cannot use this api for authentication. As they write under the limitation as:
Authentication — Instagram Basic Display is not an authentication
solution. Data returned by the API cannot be used to authenticate your
app users or log them into your app. If you need an authentication
solution we recommend using Facebook Login instead.
But looking at their API reference I get they provide oauth tokens and authentication flow /scopes.
Their getting started guide also list down steps to setup app. Anyone please explain what I am missing there ? I am looking for social login solution using instagram, thanks.

How can I use a JWT properly, to grant access to restricted REST API calls?

I hope not to be duplicating any question, and also not to be asking something too basic.
I´m building a web app in ReactJS, just to get familiar with the framework. I planned to grant access to users using a Facebook login, which I already have working with react-facebook-login. I also have a Spring Boot Rest API, to serve the front-end. But I want to allow access to part of my API just to authenticated users, using the Facebook access token. So in my back-end, I had to do an org.springframework.boot downgrade from 2.0.4.RELEASE to 1.5.10.RELEASE so I can use the Facebook Graph API. Do you guys think this is ok? or should I use a different approach?
And to be honest I´m a little confused on how to achieve a correct validation of the user's request on the restricted areas of my REST API using the access token sent from the front-end, Do you guys have any suggestions on this matter?
Thank you all for your help.

How to make an authenticated oAuth call with HwiOAuthBundle

In my symfony project, I have integrated HwiOAuthBundle for different social logins (twitter, facebook and google) and everything is working perfectly. We are collecting the oAuth tokens for each of these providers as well as the user id.
Now my question is, how can I make an Authenticated API call to one of these services using these tokens with the help of HwiOAuthBundle (or any other way) from my symfony controller
Any help will be highly appreciated.
For facebook, just call the graph API passing it the FB access token you saved in your DB: https://graph.facebook.com/.....?access_token=
same for linkedin, just use oauth2_access_token= instead
probably same/similar things for the other providers
Worked for me.
Don't think that it is possible to do what you're asking. HWIOAuthBundle don't even save the tokens to DB by default.
Once you have the token, I think you need to use bundles/wrappers dedicated to each API.

how can get data from facebook api and write those data in my own database using web services?

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.

Facebook Connect - Switched from JavaScript Authentication to OAuth - Re-Authorization?

In version 1 of my website, i implemented Facebook Connect with the JavaScript API. This included authentication, permissions, and publishing.
In version 2 of my website (what i'm implementing now), i have implemented Facebook Connect with the Graph API (OAuth).
I haven't touched the Facebook settings in my application. But when i attempted to authenticate using OAuth, it asked for the same permissions again (email, basic information) - even though i had already granted those before (using version 1)
The only difference i can see if that previously i asked for permissions via FB.showPermissionsDialog, now i use the scope parameter in the login page URL (OAuth).
What this means is when i go live, all my users will have to re-authorize my app, when they in fact shouldn't.
Any ideas? Is it because i'm now using AppId/Secret (OAuth) instead of ApiKey/Secret (JS API)?
FYI i'm using the Facebook Connect C# Toolkit.
I don't think that makes sense. Are you using the same application id? The permissions are between the application and the user, as far as I know.
Problem goes on unsolved, but site is live so not much i can do about it now.
Not a huge deal anyway.
I think you need to validate your oauth using javascript-sdk:
Check this response hope this gives you some idea.
