ASP NET Web API google authentication issue HTTP 404

I am trying to setup a social login for my site.
Here is what I did:
I created credentials on google and have both ClientID and Secret
In default MVC app, in App_Start Startup.Auth.cs I uncommented
app.UseGoogleAuthentication()* method, so it looks like this:
Build solution!
Made sure authorized JavaScript origins and Redirect url are correct. And other things that are needed on console.cloud.google.com are done. Including activation of Google+ API
Eventually Google authentication button should appear in _ExternalLoginsListPartial partial view. But as I can see I have 0 login providers still. And not sure why, and what can I do about it?
var loginProviders = Context.GetOwinContext().Authentication.GetExternalAuthenticationTypes();
//loginProviders.Count() here returns 0
Tried researching, but most are saying that you forgot to build, or restart the server. Tried that but nothing changed.
As last resort, I tried following a tutorial https://youtu.be/WsRyvWvo4EI?t=9m47s
I did everything as shown there, I should be able to reach api/Account/ExternalLogins?returnUrl=%2F&generateState=true url, and receive callback URL from Google.
But I got stuck with same HTTP404 error at 9:50

To answer my question, everything turns out to be fine.
All I had to do was just to give it some time.
After couple of hours, Google provider appeared on the page.

For future readers - if met with 404 in this case, another possibility is an active filtering rule against query strings in IIS. One of the commonly copy-pasted rules aiming to block SQL injection requests scans the query string for open (to catch OPEN cursor). Your OAuth request probably contains this word in the scopes section (data you want to pull from the Google profile)
IIS -> Request Filtering
Switch to the tab "Rules"
Inspect and remove any suspicious active filters there

Attask - Create a new user via API

I am integrating a .Net application with Work-front, I am supposed to create a new user in work-front from API. I have tried the steps mentioned in the link and my code https://{mycompany}.attasksandbox.com/attask/api/user?updates={emailAddr:testuserAPI#domain.com,firstName:testuser,lastName:API}&username=myname#domain.com&password=password&method=post
From my console application I get internal server error 500. From fiddler I get parse error.
https://{mycompany}.attasksandbox.com/attask/api/5.0/user?updates={"emailAddr":"testuserAPI#domain.com","firstName":"testuser","lastName":"sample","roleID":"testrole","password":"pwd123res"}&method=post&sessionID=sdfdsdf1
Above code gives unrecognized URI format: too many parts - exception
Though my requirement is to authorise using API key, I was trying possible ways of achieving it.But I am not able to create in any of the ways.However, I am able to create from UI, which confirms my ID has rights to create user. I did look into API explorer and could see named functions,but whats the approach?Is there any documentation for these complete steps? My search was in-vain. Please suggest as I am new bee to workfront. Thanks in advance!
Update 1:
I was able to create a user via the API authorising by both API key and sessionID. The parameter I missed to pass is username (not necessarily an existing username). My code is -
https://{mycompany}.attasksandbox.com/attask/api/user?updates={"firstName":"Test","lastName":"API","username":"TestAPI#domain.com","emailAddr":"test2#test.com"}&method=post&apiKey=t---------------------u
My first step is resolved. There are 2 more steps which I need to perform. Calling named action - assignUserToken. I tried the code as below and it didn't work
https://{mycompany}.attasksandbox.com/attask/api/5.0/user/ID=4556ffs3324?action=assignUserToken&apiKey=t---------------u&method=put
ID is value returned while creating a user. Error returned is -
{"error":{"class":"java.lang.IllegalArgumentException","message":"null objCode"}}
Can you share the syntax of calling this named action?

Hi Your call has a few things wrong with It
1st you are calling
api/5.0
this needs to be
api/v5.0
2nd you are calling
api/v5.0/user/ID=4556ffs3324
it should be
api/v5.0/user/4556ffs3324
Other then that I dont see anything else wrong with the call.

Creating a user via API is a 3 step process as mentioned in the link but it doesn't have syntax. The syntax and steps are as below.
Create user -
https://{yourcompany}.attasksandbox.com/attask/api/user?updates={"firstName":"Test","lastName":"API","username":"TestAPI#domain.com","emailAddr":"test#domain.com"}&method=post&apiKey=-----0l
This would return a uniqe ID on response. Use this ID value for next step.
Assign userToken -
https://{mycompany}.attasksandbox.com/attask/api/v5.0/user/12345?action=assignUserToken&apiKey=d---l&method=put
ID value is 12345. This would further return a token. Use this token value for next step.
Complete userRegistration- https://{mycompany}.attasksandbox.com/attask/api/v5.0/user/12345?action=completeUserRegistration&updates={"firstName":"Test","lastName":"API","token":"0--ab","title":"testUser","newPassword":"Password01"}&method=put&apiKey=dqy---3
That completes all the process. Now check in workfront UI.

Keep getting Error: redirect_uri_mismatch using youtube api v3

Hi I hope someone can help me out here.
I have a Web Application (asp.net) on my local machine, I am trying to upload video to YouTube using this sample https://developers.google.com/youtube/v3/code_samples/dotnet#upload_a_video
I have set up client id and secret for Web application in Google console when I try to upload video a browser tab opens to select one of my google accounts and once I sig in I get redirect_uri_mismatch the response details on that page are below:
cookie_policy_enforce=false
scope=https://www.googleapis.com/auth/youtube.upload
response_type=code
access_type=offline
redirect_uri=http://localhost:55556/authorize/
pageId=[some page id removed here for security reasons]
display=page
client_id=[some unique id removed here for security reasons].apps.googleusercontent.com
one interesting thing is that the redirect_uri=http://localhost:55556/authorize/ is completely different from the one set up in Google console and the one in client_secrets.json also each time I get the error page the port number changes.
redurect urls and origins are set as follows in Google console I think I have added all combinations just in case:
Authorized redirect URI
http://localhost/
https://localhost/
http://localhost:50169/AddContent.aspx
https://localhost:50169/AddContent.aspx
http://localhost:50169
Authorized JavaScript origins
http://localhost/
https://localhost/
http://localhost:50169/
https://localhost:50169/
I am not sure why redirect-uri on the error page does not match any of the
Authorized redirect URI I have specified in Google console ? any ideas ?
Also is it possible that everything is set-up correctly in Google console and my code but this error is triggered by something else like maybe I missed some setting on my you tube account ? I did not make any setting changes since I don't think I have to is that correct ?

Ok I belive that direct video upload to the website owner account is no longer supported in YT API v3.0 according to those posts.
Can YouTube Direct Upload to a Common Account for All Users?
How can I get the youtube webcam widget to upload to one account using API?
Shame, I think I will need to host the videos that users upload on my servers.
However the original issue was fixed by adding this URI to the redirect URIs in the developer console
http://localhost/authorize/
Google OAuth 2 authorization - Error: redirect_uri_mismatch

I got it to work by setting the Redirect URIs to exactly this:
http://localhost:50517/signin-google
Note:
- it does not work with a trailing slash
- port number is whatever your visual studio is assigning
- I set JavaScript Origins to:
http://localhost:50517/
With you, though, would be nice if someone actually documented this somewhere...

You should look into your code where you create the authorization URI. You need pass one of the redirect URIs you registered with Google developer console. I guess you're using some OAuth2 library which uses the localhost:port/authorize as the default redirect URI. The port changes because each time you start your local server, it picks a different port number. To fix it, you should specify a port number when starting it, for example, 8080. Then you should register localhost:8080/AddContent.aspx in Google developer console and pass it to whichever library you use to create the authorization URI.

I experienced a similar problem when trying to setup the quickstart app for the Drive REST API. I kept getting the redirect_uri_mismatch error and the port number with that error kept changing. The fix for me was to change the redirect URI in the Google Developers Console for my app to not include the port number.

There is a really easy way to get round this and I kicked myself when it dawned on me.
I am using "Web Application" credentials - you'll want the credentials manager open btw.
Run the DotNet sample app and let the browser open (I get the "Select An Account" page) - then look in the URL for the redirect URI that's been automatically generated by Google's code something like:
redirect_uri%3Dhttp://localhost:62041/authorize/
Then just go to the credentials manager and add this URL to the allowed list and save. Now select your google account and see what happens - it takes a few minutes for the API to update - if you get the redirect error page just hit back and select you account again - eventually it works and returns back to visual studio.
Once the account has been authorised once it sticks (clear the bin directory to unstick it) but this means you can now put a break point in the code and look at the credentials variable to get the refresh token everyone is so desperately trying to get so that you can persist account connections.

Can I Generate a Password Rest Token in mvc 3?

I have an MVC 3 application, in which I am using actionMailer to send out emails (to the C drive for now) for Password reset etc.
The problem is I can send the e-mail and password reset no problem however there is nothing to stop the user from using that same email over and over again.
So I believe I need to send a token with the e-mail.
I've being trying to use...
var token = WebSecurity.GeneratePasswordResetToken(email);
I get following error...
You must call the "WebSecurity.InitializeDatabaseConnection" method before you call any other method of the "WebSecurity" class. This call should be placed in an _AppStart.cshtml file in the root of your site.
UPDATE: Basically I'm looking for the steps involved in doing the above for an MVC 3 application!
I have no webpages tables in my database and would prefer not to have to add such tables now.
I have searched around the web and keep getting answers related to MVC 4, which as far as I can understand as built-in facility for the above.
I have webMatrix.WebData in place in my references folder, and have set "CopyToLocal = true".
If anyone as any advice can you please be as detailed as possible in your suggestions, also I can post up whatever additional code needed. Please keep in mind this is MVC 3 application.

ASP.NET MVC Configuration Manager error

The WSAT throws the following irrespective of the project or the connection type,
An error was encountered. Please
return to the previous page and try
again.
Even on a brand new ASP.NET MVC 2 website where user authentication and registration work through the default account controller without a quibble, the WSAT fails to run.
Things I've tried,
Tried to open it in IE.
Tried to use it with MySQL to setup
user authorization, role and profile
management. This was the goal which
is starting to seem more and more
like an uphill battle.
Tried it with a brand new ASP.NET
MVC 2 application.
Help would be greatly appreciated.

Found it. Apparently the configuration manager will not work if the directory path to the solution contains invalid characters, in my case it was a space.
Should be documented somewhere, this was a good waste of four hours..
