Lumen Socialite authorisation flow - laravel

Info
I'm looking for some clearification for using the Socialite package in a Lumen project. I want to use OAuth2 so users can authenticate with theire Google, Facebook or other social account on our applications.
To my understanding Socialite redirects to a page of the selected provider, asks the user for permission and return to the application with the authenticated user object. I made a base setup with a Laravel application and this all works fine.
The problem
I have an authentication API (Lumen based) where user credentials are validated. This is only a backend service. The actual user credentials are received from different front-ends (applications). Do the frontends need to implement OAuth2 / Socialite and send the social user details to my authorisation API or can the API arrange the whole OAuth2 process?
I don't quite get it how the redirection should take place in an if the whole flow is arranged by the API? There is a stateless() option available in socialite and i found some information where socialite is used in Lumen but then i don't get the whole redirect / authentication flow.
Options
Different optios
Like to hear from users if this option is possible, hope my question is clear. :)

Just to update on my own question;
After some research i found the flow to be like this:
-> Frontend handles the user request to be authorised by Oauth2 with a specific provider. (we get redirected to a page of the provider asking about permission for this application). This can be done with socialite (in case of Laravel) or any other package for a specific framwework.
-> An Access token is received by the frontend and send to our Lumen backend service. Here we can use Socialite again to get the user details for this access token. The user details can then be used to create a new user or attach a social login to an existing user. When access token is valid and user is created or found in existing user, the user can proceed in the application.
Hope to help someone in the future with the same questions :)

how user get token for subsequent request after loging in particular app by Google account

I'm a newbie in web development. Currently, I've learnt laravel framework and be researching about passport and socialite. I'm being stuck that after logging in the application successfully by their Facebook account how users get the access token for subsequent requests.
This has been implemented using Laravel Socialite. You can follow each step to implement Laravel Socialite.
You will get the information on how to create Secret Key & Access Key for social login.

Which OAuth2 Grant to use when developing SPA, Mobile App with Laravel as backend. Will not be using third party login

I'm developing a mobile app + SPA using Laravel as a web service. I'm not sure which grant flow will be good for this. I would avoid any third party login like facebook, google, etc. Id'like to handle user login simply with email and password. I want user to login only once on mobile app.
I had gone through some articles. I'm very confused. I found out 2 flows which might work here. 1st is implicit Grant & 2nd one is password grant.
If SPA is built inside your Laravel project you can handle user login simply with standard laravel authorization method.
For external use (mobile app or external SPA) you should authenticate users with API.
Laravel Passport mainly offers two way to handle this.
Personal Access Token
Fresh API Token
I suggest using the second one cause is the "Standard way" to consuming your web app with a nonsecure source.

confused on usage/difference of SSO/OAUTH/SOCIAL LOGIN

I have an app idea and need to implement authentication. Because of the nature of my app, I only want linkedin users to be able to access my app.
After reading a bit about spring oauth / spring social / etc, it seems its definitely possible to use something like Linkedin to access MY app. I want a user to see linkedins login button on the first view of my app, create my own version of this user in my app, and then allow the user to use my app.
After my findings I have found the generic flow
*user authenticates via social login button
*client app redirects user to service provider to receive a token
*client uses token and makes another request to service provider to receive auth token
*now my client app can make calls to service provider with auth token of user(this is the part where I am a bit confused)
*I want to use this token to validate calls against MY api NOT linkedins(is this wrong)
I don't really care to make calls to Linkedin on behalf of the user(except to pull user information). I ONLY want linkedin auth so that I know that users who use my auth are valid linkedin users. I thought something similar to Tinder where you MUST have a facebook account, I want to copy that design but couldn't find any hints from google. It seems the examples I find online all use the social login to ultimately use the service providers API.
I also read some stuff about SSO which sounds like what I want, but I definitely plan to add at least 1 more social login down the road. My clients will use a browser or mobile app.
I guess the main question here is once I authenticate a user using social login, am I supposed to use his existing connection to make calls to my API or create a new connection somehow. My goal is when a user does a social login, he now can access MY app, I want to reuse their existing connection without authenticating them into mine(only store their info). I want to follow best practices.

Laravel Stormpath Social Login Error

I am using Laravel 5.1 and Stormpath for User management.
I followed this documentation to implement google login
Configuring Your Social Provider = DONE
I created project in Google Console and in “Authorized redirect URIs” I've added
https://{DNS-LABEL}.apps.stormpath.io/authorize/callback
Create a Stormpath Social Directory = DONE
Initiate Social Login - In my form when I click on Google Sign In it redirects to
https://{DNS-LABEL}.apps.stormpath.io/?response_type=stormpath_token&
account_store_href=https://api.stormpath.com/v1/directories/{id}
&redirect_uri=https%3A%2F%2Flocalhost
and returns
{"status":404,"message":"Resource not found."}
As per this documentation:
The user clicks on a “Login with Google” link pointing at your application’s /authorize endpoint
Stormpath handles the login to Google and redirects the user back to your app with a Stormpath Token JWT response
What am I doing wrong? Why isn't stormpath redirecting to the google login page?
It looks like the URL that you are creating is missing the /authorize part. If you update your URL to be
https://{DNS-LABEL}.apps.stormpath.io/authorize?response_type=stormpath_token&
account_store_href=https://api.stormpath.com/v1/directories/{id}
&redirect_uri=https%3A%2F%2Flocalhost
It should begin working for you.
In a future release of the PHP SDK (which powers the laravel integration), we will be able to generate this URL for you.
If you are using our Stormpath/Laravel integration, the views provided will automatically handle social logic for you. If you are doing this from scratch, it may be worth a look at https://github.com/stormpath/stormpath-laravel

Login via Facebook into OpenAM using REST

I am looking forward to integrate logging in users using Facebook's authentication. I have my app protected by OpenAM and the users are already registered there. I have my own login page and would not like to move this to OpenAM and retain it in my app. As of now, I am using REST calls to authenticate users in OpenAM. Now, I want to integrate login using Facebook. My idea of implementation is as following:
User logs in using original credentials and is authenticated in
OpenAM.
User is asked to associate his/her Facebook account with the
OpenAM account.
User authenticates his/her Facebook account
(https://www.facebook.com/dialog/oauth?app_id={app-id-as-created-in-fb-developers-console}&redirect_uri={my-rest-service}).
This will return the code and that can be used to recheck against
Facebook to ensure that the user was authenticated against my app
and this is not a hacker intervention
(http://graph.facebook.com/debug_token?%20input_token={code-returned-from-facebook}&access_token={my-app's-access-token}.
The response will contain the app ID that can be verified against my
App's ID. On success, I shall call OpenAM to associate the user in
OpenAM with his/her Facebook credentials (Not sure what all to use
here.)
Next, whenever the user wants to login, he/she can use Facebook
login where in the redirect URL would be my REST service and the
code returned from Facebook can be rechecked from Facebook and then
OpenAM will be called to authenticate.
My queries:
I am not sure if this approach is feasible.
How do I pair an existing user in OpenAM with the Facebook account?
How do I authenticate the user in OpenAM after Facebook login, with
the userID?
Is the Facebook userID (numeric,returned from Facebook graph in JSON
response), unique and permanent?
I would also want to give the users an option to de-associate the
existing Facebook account and associate a new one-how do I do this?
Apologies for asking too many questions, but I am new to OpenAM and OAuth and keen on following the approach I have mentioned above.
Thank you.
As an aside, it will probably be much easier in the future if you delegate all of the login to OpenAM, and let it deal with local login and social. This will make it really easy to add more social providers.
If you want to keep your current architecture, you can create a new authentication chain in OpenAM that just has social (facebook) login. You should be able to redirect the user to that chain. Once the social login process is complete, you can have OpenAM redirect back to your application page.
To link local and social login you are going to have to offer some kind of account claiming in your application. After they do a social login you could ask them to link their local account by providing the username and password. You can call OpenAM's REST API to validate the credentials.
This kind of linking can be confusing for users - so sometimes it is better to treat them as separate accounts, or have a migration process for the user to migrate to social only.
