Post to Facebook on behalf of my web application users - Laravel - laravel

I have created a web application and I would like users to be able to log into their own Facebook account to publish posts on their Facebook profile from my web application.
Every time I connect them to Facebook with authentication, I get back a token that does not retain the requested permissions, especially "write to profile".
I am on Laravel.
I have tested with PHP SDKs, with Socialithe and even with PostMan. I can't find the solution.
Do you know if this is possible? And how?
Thanks

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.

Chat bot single sign on

I have a bot running on a hosting page where users are logged in using SSO.
I want to authenticate the user in the bot automatically when the bot starts and I do not want to use anAuthCard to do it. Just want to automatically authenticate the user without prompting anything to him, just using SSO.
I found an article that refers three ways to authenticate an user in the bot:
Sharing the client's user token directly with the bot via ChannelData
Using an OAuthCard to drive a sign-in experience to any OAuth provider
A third option, called Single Sign-On (SSO), that is in development.
And, according to the article my situation is:
WebChat in an authenticated website where the user is already signed in and the website has a token to the same identity provider but to a different app that the bot needs -> in the future, this is single sign-on, but for now you 'll need to use an OAuthCard.
Is there any update about this functionality? How can I authenticate the user into the bot without using an OAuthCard or a SigninCard?
Thanks in advance
Not sure if you have tried the option of using WebChat with Azure Bot Service’s Authentication which provides built-in authentication capability to authenticate chat users with various identity providers such AAD, GitHub, Facebook, etc.
If you are looking for this built-in feature, then probably you need to build your own custom built solution using Google sign-in by passing the token ID of the authenticated users. Or for an Account linking OAuth2 solution as explained in this link: How to implement Login in Dialogflow chatbot.
Microsoft guys Are looking at the issue now. you can track the progress here.
I implemented a solution that worked for me. I have the bot running in a .net core web app
Here's what I did:
Generate an userId before initializing the BotApp
When the user clicks on the button to open the webchat, I'm opening an authenticated controller in a popup that receives the generated userId. The page is authenticated, so you will need to authenticate. I store the userId in my DB, along with access_token and some user information. The controller should be created in the same webapp where the bot is running.
After storing all the information I close the tab and start the BotApp with the generated userId
In bot code you will be able to query your DB (using userId).
To wait until the popup close, you can have a look into this here.
I hope that this helps someone.
Best regards

Integrating Social Logins with own OAuth2 REST API server

I am trying to make a mobile app in React-Native and Server in Spring-Boot which have a OAuth2 implemented API endpoints.
My question is how can I integrate Social Logins into my React-Native app which in save a user in my user table. apart from Social login I am using naive register/login flow which require username/password to provide access token from OAuth2 Server. How can I do the same with Just Social Login without prompting user any password or other extra information.
any general solution for this will help regardless of tech I am using.
Thanks
Usually when using social networks to login/sign up you'll get a token returned in your app which you can send via your REST API and on your backend it can then retrieve the users information from the social platform used depending on the granted scopes(e-mail, username, etc...) and store the retrieved values in the database.
Thats basically how it works in general, but if you want to have more information you probably still need to share some more info about your tech used.
Hopefully that helped you out ;)

Undisplaying the permission screen for each user. (Case: Using API don't support Service Account authentication)

We publish an app that use OAuth 2.0 API access on Google Apps Marketplace. It got reviewed by Google and they said our app is invalid because it shows permission screen when a user first runs the app. (The app will be removed from the Google Apps Marketplace if our app is not fixed within 30 days) To solve this issue, we have some problems.
Our app uses OpenID Connect to make users login.
Our app also uses Spreadsheet API and Calendar Resource API (OAuth 2.0 Web Application Flow)
So our questions related above is the followings:
1.
Although our app uses OpenID Connect for login, using OpenID Connect forces our app to show the permission screen. Doesn't it meet the best practice below of Google Apps Marketplace?
https://developers.google.com/apps-marketplace/practices#5_use_one-click_single_sign-on
We followed the OpenID Connect document provided by Google:
https://developers.google.com/accounts/docs/OAuth2Login
2.
Since Spreadsheet API and Calendar Resource API don't currently support the authentication method using Service Account with OAuth 2.0, we chose to use the method of Web Application Flow. Our app get the token when users login, but Google said to us that it fails to meet their SSO requirements. To solve the issue, we are thinking to change our app to authorize AFTER login within the app instead (use Web Application Flow method as it is). Does the way meet the SSO requirements? In other words, is it OK to show permission screen if after login?
We will applicate if anyone can tell us good solution to solve these problems.
Thanks,
If you register your scopes in the Google Apps Marketplace configuration screen, and then only request those scopes in the OpenID Connect flow, then the permissions screen should be automatically skipped. Please ensure the scopes match between these two locations.

How to manage a user session using Azure Mobile Services?

I'm building mobile applications using .NET. What I'm looking for is a way to manage user sessions and info using Azure Mobile Services. I've read a lot about the authentication in Azure Mobile Services, but this only authenticates a user via Facebook, Twitter, etc ... to access azure services.
I'm looking for user session management, i.e. register, login, logout. Be able to save and retrieve user info, i.e., save certain info against the user such as age for example. Also session management and caching, i.e. the user will remain logged on when the app is closed and re-opened. Also azure mobile services doesn't seem to provide a way to allow me to register users via email.
Basically, If anyone is familiar with Parse, I'm looking for having similar functionality in Azure. Can anyone help please ?
Thanks
Out of the box, Mobile Services provides easy authentication with social providers (Facebook, Twitter, etc) and Azure Active Directory. If you want to do registration via email, you'll have to create a custom auth system. This is going to be more complex than just flipping a switch and using Facebook auth, but totally doable and I can point you in the right direction. First, check out this post that will explain how you can create a registration / login system using custom API and the script backend. If you're using a .NET backend, you'll need to alter thing a bit (the samples are in JS) but it should be pretty easy to convert. The only piece that is really missing from that post is how to do email verification. To do this with Mobile Services, I would suggest the following.
Sign up for a SendGrid account (free in the Azure store)
From your script, after registering the user, generate a random alphanumeric string that is saved to their account / user record in the table.
Use the same string to create a URL which you can send to the user's email address (check out this tutorial for sending email via SendGrid and Mobile Services).
The link can either go to a different custom API or a web front end. When that endpoint is hit, it should update the user record to show that they have verified their email address.
