I'm using this as a reference:
https://code.google.com/p/google-api-javascript-client/wiki/Authentication
I'm trying to authenticate a user and then fetch his/her google_id after auth.
I have a button called "login with google" and when the user clicks on it, it launches a popup that asks if he/she wants to give authorization to the app. After that
it throws an error saying "bad request" and "400 not found" when it tries to do a GET on this
https://www.googleapis.com/discovery/v1/apis/plus/v1//**/*** 400 (Bad Request)
I'm using the same code as described in the above mentioned api.
I also crosschecked the api key and client id, but everything seems fine.
Any help on this?
Your best bet is to move to Google+ Sign-In. It uses the same JS client but does a lot of the hard work for you.

We have an application that uses Dropbox API. When the user goes through the Dropbox OAuth 2 flow and signs-in using their email address and password, all works fine and we get the access_token. However, when the user uses the "Sign in with Google" flow in the Dropbox authorization dialog, we get back code which we then try to exchange for access token but the request fails with {"error_description": "code doesn't exist or has expired", "error": "invalid_grant"}.
Here's the steps we use:
1.
var dbx = new Dropbox.Dropbox({ clientId: clientId });
var authUrl = dbx.getAuthenticationUrl('https://www.dropbox.com/1/oauth2/redirect_receiver');
This gives us url https://www.dropbox.com/oauth2/authorize?response_type=token&client_id=...&redirect_uri=https://www.dropbox.com/1/oauth2/redirect_receiver.
2.
Open authUrl in a popup.
3.
User uses "Sign in with Google"
4.
We get a redirect to the URL below that contains the code:
https://www.dropbox.com/google/authcallback?state=...&code=...&scope=...
Now trying to exchange the code for access token with POST to https://api.dropboxapi.com/oauth2/token gives us:
{"error_description": "code doesn't exist or has expired", "error": "invalid_grant"}
The problem here is that, given the use of the Google Sign In flow, there are actually two OAuth authorization flow instances occurring; the Google Sign In flow is nested inside the Dropbox app authorization flow. Your app doesn't actually need to know about this though.
That https://www.dropbox.com/google/authcallback URL is Dropbox's redirect URL for the Google Sign In flow, and accordingly the code given there is for the Google OAuth flow, not the Dropbox OAuth flow. Attempting to use it for the Dropbox OAuth 2 flow will accordingly fail as you've seen (since it actually came from Google, not Dropbox).
You should have your app wait until your own redirect URL (in your shared code, https://www.dropbox.com/1/oauth2/redirect_receiver) is accessed, and only then take the code from there and exchange it for a Dropbox access token.
I want to make a website which users can see their posted pictures on the page.
I have signed up for facebook API and have an app id and app secret.
https://graph.facebook.com/oauth/access_token?client_id={#}&client_secret={#}&grant_type=client_credentials
I send users to the oauth to get the user's access token but I don't know what to do next.
https://graph.facebook.com/v3.0/me?fields=id,name,posts&access_token={#}
I thought this would work but I had the error below
"An active access token must be used to query information about the current user.",
The URL you are using to get the Access Token is actually an App Token API.
To generate the Access Token Please replace
https://graph.facebook.com/oauth/access_token?client_id={#}&client_secret={#}&grant_type=client_credentials
with
https://www.facebook.com/v3.0/dialog/oauth?response_type=token&client_id={#id}&redirect_uri={#}&scope=publish_pages
add a redirection url here where the token is published.
OR
better option is to use the login button mentioned here.

Also you can read here about all Access Tokens

First, I'd like to mention that problems like this had been discussed before in the topics like:
How to authenticate user with just a Google account on Actions on Google?
But I could not find any information at all related to ways of linking Google Assistant app with my own web server.
Problem:
GET https://oauth-redirect.googleusercontent.com/r/my-google-assistant-app#access_token=ACCESS_TOKEN&token_type=bearer&state=STATE always returns "Account field to link" error
A Way to Reproduce:
I created a new project in Actions on Google Console
I built an application using Dialogflow
I created a Heroku Web Server as my webhook (ex: webhook.herokuapp.com)
So everything worked just fine. I've successfully connected my Google Assistant app with my webhook.
But then I decided to send requests to my another one Heroku Web Server (ex: webserver.herokuapp.com) which needs a user to be logged in. So I decided to implement account linking of my Google Assistant app with webserver.herokuapp.com
I implemented Google-OAuth2 authorization at webserver.herokuapp.com. Also I want to mention that I used Client ID and Client Secret of my Google Assistant App
So, Google Authorization worked perfectly at my webserver.herokuapp.com
Then I enabled account linking settings for my Google Assistant app with Implicit Flow
So, that's it!
Epilogue
I open Google Assistant, tell it "Talk to my test app", then it greets me and offers me to link accounts. I say "yes".
Then I see how Google Assistant requests my login URL at webserver.herokuapp.com. Then I enter my Google email and password. As a result I logged in at my webserver! Then my webserver makes a redirection to:
https://oauth-redirect.googleusercontent.com/r/my-google-assistant-app#access_token=ACCESS_TOKEN&token_type=bearer&state=STATE
And I get the error I've described at the top of my post.
Any help would be appreciated
UPDATE with parameter information
These are my constants:
Google Assistant Project_ID = nodejs-sdk-local-test
Google Assistant Client_ID = 1067979601708-ldr3ga115es3fdo823slfnj46gjoes66.apps.googleusercontent.com
state = manually_set_state_value
The flow is I open my Google Assistant and say "Ok Google, talk to my test app", it answers my request and then I say something like "do some action which need authorization". Google Assistant app offers me to link an account and I say "Yes".
This is where Google Assistant app makes a call to my https://webserver.herokuapp.com/google-oauth2 endpoint. A purpose of this endpoint is to redirect me to the Google Login Page.
Now I'm being redirected to the Google Login Page (everything seems to be correct. client_id and state parameters are similar to the constants). This is the example of an URL where I am being redirected to: https://accounts.google.com/o/oauth2/auth?client_id=1067979601708-ldr3ga115es3fdo823slfnj46gjoes66.apps.googleusercontent.com&redirect_uri=http://webserver.herokuapp.com/complete/google-oauth2/&state=manually_set_state_value&response_type=code&scope=openid+email+profile
At the Google Login Page I enter my credentials and then I'm being redirected to the redirect_uri=http://webserver.herokuapp.com/complete/google-oauth2 endpoint. A purpose of this endpoint is to register or login me at webserver.herokuapp.com and then redirect me to another Google URL. An example of the Google URL: https://oauth-redirect.googleusercontent.com/r/nodejs-sdk-local-test#access_token=<token_omitted>&token_type=bearer&state=manually_set_state_value
So it seems that everything is correct. I logged in to my webserver.herokuapp.com, got an access token. Also project_id and state parameter in the last Google URL are similar to constants. Anyway, this Google URL returns me an error "Accounts failed to link"!
The most common cause of this is that you're not passing back the same value for state that was sent to you when Google redirected to your site. Make sure this is the same value and, for your security, make sure you validate the other parameters that are sent to you as well.
When the user is redirected to https://webserver.herokuapp.com/google-oauth2, there should be some parameters sent as part of the query. Those parameters include a state parameter. It should look something like this:
https://myservice.example.com/auth?client_id=GOOGLE_CLIENT_ID&redirect_uri=REDIRECT_URI&state=STATE_STRING&response_type=token
Note that while the client_id and redirect_uri are values that you should expect and test for, the state value is not one that you would have set. Google generates a different one every time. This is the state that you should be using later when you redirect to
https://oauth-redirect.googleusercontent.com/r/nodejs-sdk-local-test#access_token=<token_omitted>&token_type=bearer&state=STATE_STRING
I would like to develop a desktop application.
Sadly I got stuck at login. I want to use a web view which be SoundClound login end point.
https://soundcloud.com/connect?client_id=my_client_id&response_type=token_and_code&scope=non-expiring
Using the above I received error : "invalid_client: The configured redirect_uri of the client application is invalid."
Would be nice if API would tell you which parameters are required and which are optional. As I read about OAuth 2.0, redirect uri is optional. This caused me confusion when received this error. I also tried curl version, same kind of error.
If I tried to add a random redirect_uri won't pass either. (I'm aware this is about security.)
I found this answer, but I doesn't work and I think is error-prone: it requires 2 text fields and you're asking the user to provide their credentials (then you're able to do what you want with them...)
Soundcloud API authentication without a web browser
I would like to do the flow this way:
Open a web view with SoundCloud login end point.
User is providing his credentials to SoundCloud Server.
SoundCloud Server is sending me a token.
Something similar to OAuth 1.0.
Is possible or is there something similar to achieve my goal?
After another few hours of research and keep trying to login I figured it out.
It works with redirect_uri after I did the setup for it on page "Your apps" on SoundCloud.
From my google chrome browser I enter:
https://stream.twitter.com/1.1/statuses/filter.json?track=canucks
I get a window "Authentication Required". I have set up a Developer app in my twitter account. I enter my twitter User Name and my Password, and press Log In, but it keeps giving me the same Authentication Window. Any ideas what the problem could be?
In the Authentication Required window I see the text:
"The server https://stream.twitter.com:443 requires a username and password. The server says: Firehose."
The problem is that authorization with header info is needed. It is more complicated than the simple URL above. It is best done by writing some code with the authorization header needed, along with the above URL.
