PayPal API Sandbox - "For security reasons, this page is no longer available" - asp.net-mvc

I'm working with the PayPal API and am trying to create an account as shown here.
The request is made to https://svcs.sandbox.paypal.com/AdaptiveAccounts/CreateAccount.
I'm able to send a valid request and get a response indicating success back but the redirect URL that's also returned as part of the response payload (which according to their docs is supposed to take the user to a PayPal sign up/registration page) is directing them to the following:
I've been unable to find anything on Stackoverflow or Google regarding this. Has anyone encountered this before? I'm assuming that even though it's a sandbox environment it should allow me to simulate the workflow somehow. I've tried with both the default sandbox credentials as well as for my own environment.

Looks like the issue was due to the IP address header in the request. The default configuration is:
-H "X-PAYPAL-DEVICE-IPADDRESS: 192.0.2.0"
While testing on localhost, I changed it to:
-H "X-PAYPAL-DEVICE-IPADDRESS: 127.0.0.1"
Also had to ensure that the email address didn't already have an account registered to it - in which case it would lead to a login page instead of the registration page (which is a little poorly designed in my opinion since you can't really test without making new accounts each time).

Account linking with actions on google

I am facing an issue regarding account linking in Actions on Google:
I am able to authenticate the user and access his email address and username however after this how can I redirect the user back to the google assistant and close the browser where he was authenticated?
Any help will be appreciated!
Update: Hey Prisoner thanks a lot for that.
I did what you said and yeah now it does redirect to google.com but without result_code=SUCCESS when I test it in the simulator.
The link is:
https://www.google.co.in/?gws_rd=cr&dcr=0&ei=z77fWbjQGIXxvATs_oqwBA
Now if I type talk to... again it shows me the message you need to link your account!
In the device the browser automatically closes and it shows SIGNING_IN however when I type an intent it is not recognized.
It would be great if you could point me in the right direction! (I am not sure but I might be at the token exchange stage that you mentioned, but I don't have a clue how to proceed!)
Update 2: As requested the entire flow that I am following:
This is the URL that I receive from debugInfo:
https://assistant.google.com/services/auth/handoffs/auth/start?account_name=cha***#gmail.com&provider=***_dev&scopes=email&return_url=https://www.google.com/
When I paste this in the browser the request that I receive at the authorization endpoint is:
ImmutableMultiDict([
('response_type', 'code'),
('client_id', ****.apps.googleusercontent.com'),
('redirect_uri', 'https://oauth-redirect.googleusercontent.com/r/****'),
('scope', 'email'),
('state', ' CtcCQUxWM2ROU3hNMjl4LUItVXhQSGd4THRMLU4yNExnb3lYbGRKQnQwa3NwTVFva19NUWpYNE5jNGJURzIyZFN3RDBXd2d4enFGVWJGb0Q0ZW1vaS1OaFdkaHdhb05HZ2xlWTR6SllKVlRWYktwd09faklyUTVheFhQbGw2dmVKYzVFTk05N3B1QkxaZG41RVdHN0wyTktvRFdCYzFPVFBzM1dQUlFtN2RmM1VtRU4****(state)')
])
The response (redirect_url) that I send back:
https://accounts.google.com/o/oauth2/v2/auth?scope=email&response_type=code&redirect_uri=https%3A%2F%2F******.herokuapp.com%2Fcallback%2Fgoogle&client_id=****.apps.googleusercontent.com
When it reaches my endpoint again the request arguments are:
ImmutableMultiDict([
('code', '4/***********')
])
Now I am able to access the email address and other details
The url that I redirect to from here:
https://oauth-redirect.googleusercontent.com/r/****?code=abcdefgh&state=CtcCQUxWM2ROU3hNMjl4LUItVXhQSGd4THRMLU4yNExnb3lYbGRKQnQwa3NwTVFva19NUWpYNE5jNGJURzIyZFN3RDBXd2d4enFGVWJGb0Q0ZW1vaS1OaFdkaHdhb05HZ2xlWTR6SllKVlRWYktwd09faklyUTVheFhQbGw2dmVKYzVFTk05N3B1QkxaZG41RVdHN0wyTktvRFdCYzFPVFBzM1dQUlFtN2RmM1VtRU4****(state)
This redirects me to :
https://www.google.co.in/?gws_rd=cr&dcr=0&ei=5c_fWdfKNYndvASO7o6ACA
Edit 3: I checked the network logs:
result_code=FAILURE&result_message=Account+linking+failed
I also added /token/google as the token URL in AoG. It is detected in heroku however I never receive this request in my code.
Note: I am using python flask and hosting my app on heroku
Once you have authenticated the user, you'll need to return a temporary auth code back to Google. Later, Google will exchange this auth code for an access token and a refresh token, but you're not there yet. The important part is that this code needs to be unique and that, later, you'll be able to recognize what user it is for. The code should be valid for a limited time - 10 minutes is a generally accepted time frame.
In the request Google sent to you as part of the login, they've provided a redirect_uri and a state as parameters. You'll need to use these in your reply. (state can be anything - you shouldn't care what it is, you're just going to send it back with your redirect. Its purpose is to improve security by preventing replay attacks.)
Verify that the redirect_uri has the form
https://oauth-redirect.googleusercontent.com/r/YOUR_PROJECT_ID
Where YOUR_PROJECT_ID is... you guessed it, the ID of your project. You can find this in the cloud console.
You'll then redirect the user to this URL with a few additional parameters:
https://oauth-redirect.googleusercontent.com/r/YOUR_PROJECT_ID?code=AUTHORIZATION_CODE&state=STATE_STRING
Where YOUR_PROJECT_ID is as noted above, AUTHORIZATION_CODE is the code you've generated, and STATE_STRING is the value of the state parameter that you were sent in the request.

Google Authentication via .NET/OWIN: Access_Denied

When I try to call Google to authenticate, I get an access_denied response.
I have the Google+ API enabled
This code was working yesterday and I do not see anything that would cause it to break now.
This code works in one environment (dev) but fails in another (test).
I updated our test environment to have the same code (copied from dev) and it fails there.
This seems to be server related, but I can't figure out why.
Google's configuration has all the appropriate response and redirect uris (I just changed the subdomain).
Is there anyway I can find out WHY access is denied?
One possible cause for getting a generic access denied error when interacting with Google is their block on "less secure apps": https://support.google.com/accounts/answer/6010255?hl=en
It generally returns an error that is assumed by most apps and sites as an incorrect password, even if your password is correct. If you are using different Google accounts between dev and test, and one is configured differently than the other, this might be a possible reason.

Using Email Settings API from app engine with service account

I'm trying to use the Email Settings API from within a google marketplace app. Because I need all the logic to happen offline (in a cron job). I'm using an app engine Service Account, but when I'm trying to actually change the email settings for the users of the domain that installed it I'm getting this error:
You are not authorized to access this API.
Error 403
this is the scope: https://apps-apis.google.com/a/feeds/emailsettings/2.0/
I'm probably missing something, but I couldn't find the right docs to show me the way. How would I go about implementing an app that accesses the email settings even when the admin is offline?
You need to set the prn attribute to address of an admin account.
Examples for the directory API are at:
https://developers.google.com/admin-sdk/directory/v1/guides/delegation#instantiate_an_admin_sdk_directory_service_object
In terms of accessing the Email Settings API, you're really unlikely to get people to give you Service Account access to their domain.
On the other hand, if it's your domain (and thus you can add Service Account access), couple of pointers below:
What is important is that you add the following to the header:
"Authorization" = "Bearer <your_token>"
(note the very specific syntax - "Bearer+<1 space>+", as per https://www.rfc-editor.org/rfc/rfc6750 section 2.1)
"Content-Type" = "application/atom+xml"
(important for POST/PUT/DELETE requests, doesn't matter for GET)
that should get you up and running.

Console application using the YouTube Data API

I'm about to build a console application that needs access to the authenticated YouTube Data API. Calling the API's themselves is not a problem, I know quite well how to make and process HTTPS requests.
I've already gotten the API key and the Client ID. No problems there, either.
The problem is the authentication.
I've checked here: https://developers.google.com/youtube/v3/guides/authentication#installed-apps
On the "Installed applications" tab, in step two, it instructs on how to set up a url to call to do the authentication step. All good so far. But before programming anything, I thought I'd try and see what that url does in the browser.
Turns out it just displays a login prompt. Well how about that. That won't work in this kind of console application. The idea is, presumably, that the user is somehow shown this webpage and be instructed to login and allow access. Then, somehow, by some kind of magic perhaps, the access token is sent back to my console application.
Two things I'm not quite sure about:
1) How do I prompt for the username and/or password in the console app and send that to the authentication URL?
2) How would I get the access token back from it?
The biggest problem is that the API seems to require a browser... Which isn't there. My console application will (eventually) run unattended, so starting up a browser and displaying a webpage and doing nothing until it returns a code, is out of the question. I need to somehow supply the authentication page a username/password and get back the code right away.

Soundcloud OAuth2 API: Getting invalid_scope error after user connection

I'm trying to implement Soundcloud connect and having a weird issue.
First thing I do is send my users to
https://soundcloud.com/connect?client_id=MY_CLIENT_ID&redirect_uri=http://myredirecturl.example.com&state=RANDOM_STRING&display=page&response_type=code&scope=email
When users connect they get redirected to
http://myredirecturl.example.com?error=invalid_scope&error_description=The+requested+scope+is+invalid%2C+unknown%2C+or+malformed.&state=RANDOM_STRING
The same happens if I use scope=*.
However, if I use scope=non-expiring it lets me go through, but I need the users email and that type of scope doesn't have enough grants.
I thought it had something to do with my app being in development mode, but Osman at Soundcloud said it doesn't.
Thanks.
The 'email' scope is not available to all integrations. It's used for a few custom integrations that have provided us with accepted terms of service / privacy policies. There is no way to get a user's email address using the SoundCloud API.
You should however be able to use the '*' scope to get an expiring access token. I'll check with our app team to see why this is giving you an error. I'll edit my answer once I have more information there.
For your purposes, I would stay with the 'non-expiring' scope and simply prompt a user for their email address (providing them with a way to agree to your terms of use / privacy information).
Using scope=* sometimes doesn't work because the url is not properly encoded. If you are getting this error while using the * wildcard, try properly encoding the url, using a function like urlencode() (for PHP).
