Is it possible to generate azure authorization code from application code without browser redirection?
I've credentials that are needed to generate the auth code that is needed to generate access token.
Is there a way to input the credentials via code and get authorization code using C# code and read it to a string variable?
https://login.microsoftonline.com/<tenant-id>/oauth2/v2.0/authorize?client_id=<client-id>
&response_type=code
&redirect_uri=<redirect-uri>
&response_mode=query
&scope=2ff814a6-3304-4ab8-85cb-cd0e6f879c1d%2F.default
&state=<state>
Need to pass the authorization code generate in the above code to get the access token.
If anyone can help, I would be grateful.
I tried to reproduce the same in my environment and got the below results:
When I tried to generate the Authorization code by passing the username and password parameters it still asked me to sign-in to the account:
Note that: Generating Authorization Code used Authorization Code Grant Flow which requires user-interaction. A user-agent that permits redirection from the authorization server back to your application is necessary for the auth code flow.
So, by design, when you hit the authorize URL it will be redirected to sign-in and code will be generated:
Alternatively, to access the SharePoint you can grant required Application Api permissions and generate access token via Client Credential Flow.
https://login.microsoftonline.com/TenantID/oauth2/v2.0/token
client_id:ClientID
client_secret:ClientSecet
scope:scope
grant_type:client_credentials
If Client Credential Flow doesn't achieve your scenario, then you can make use of ROPC flow (Not recommended by Microsoft) which doesn't redirect to login as mentioned by juunas.

I have a Next.js website I'm working on and a dotnet core API connected to a SQL Server database. I have a login page and intend to create a page to add new users and was wondering how I could do this using dotnet core identity? I added the NextAuth.js package thinking I could utilize it, however it seems to work best if connecting directly to the database and not go through an API.
I managed to return the token to NextAuth.js but I don't know where to go from there. How can I use next-auth to manage the session? Or is there a better way to go about doing this without using NextAuth.js?
My reason for using dotnet core identity is because it already has support for roles and setup is fairly simple and makes authorizing different sections of the API easy. Based on a user's role, they should be authorized to access certain routes or view certain pages.
I tried looking at the following doc from microsoft Intro to auth for SPA, but it's not exactly clear to me how I can manage the session.
First, generally, when we using JWT authentication, the workflow as below:
Client sends a request (which contains the user information, such as: name and password) to server for token
Server receives the user information and checking for authorization. If validated success, server generates a JWT token.
Client receives the token and stores it somewhere locally.
Client sends the token in the future requests.
Server gets the token from request header, computes Hash again by using a) Header from token b) payload from token c) secret key which server already has.
If ("newly computed hash" = "hash came in token"), token is valid otherwise it is tempered or not valid
After configure your application uses Identity and JWT authentication. When a User login, you could send the user information to the server side and check if the current user is valid or not, then generate a JWT token, and on the client side you could store the token in the web storage. After that, when you want to access the resource by passing this token into the authentication HTTP header. More detail information, please refer to the following article: JWT Authentication In ASP.NET Core
I am working on integrating Docusign Authorization Code Grant Authentication. I was getting docusign login site html code as my return so then I realized this needs to run in the browser. I ran the URL and got to the docusign login page and after logging in I can get the code in the redirect url. But my concern is how I can do this with C# code.
I had tried this with sdk as well but still i got the HTML of Docusign login page in response.
I am using the below url to generate the code.
Auth Code Grant requires that you use a web browser to authenticate and then redirect the call to your web server with a code. You can then exchange this code for an access token and that can be done from any app.
If you need a non-web app to make API calls you need to use JWT. JWT allows you to obtain the access token without any web UI. You do need to obtain consent at least once (via web UI) but that doesn't have to be done in the context of your app (assuming again you're building a non-web app).
I am trying to build an application that will be authenticating documents using DocuSign.
The person who is signing the document is going to be initiating the process and will not have any login credentials for DocuSign.
However, when I test using the JWT authentication method it always brings me to a page asking for a Username/Password. My end user is not going to have this information.
All of the Example applications do not address Authentication, they just have you copy and past the Access_Token out of their tool on the website.
How can I have an Embedded Signing application that does not require the End User to login with DocuSign?
JWT Authentication requires the user grant consent once. Once that consent is granted, the application can freely generate access tokens for that user at any time (unless consent is later revoked).
For an example of C# / .net core that uses JWT authentication, please see GitHub: https://github.com/docusign/eg-01-csharp-jwt-core
JWT allows you to specify a userId.
If you are an admin of the DocuSign account and you enabled the integration and logged in yourself at least once, then you can later make APIs call impersonating other users, if you provide their userId in the request so they don't need to login themselves.
Hope this helps
So I wanted to learn about the process of OAuth2 Authentication and decided the best way to do so would be to code the process. So using the Google Sheets API I am able to get the authentication code and redeem it for a token and then access the Sheets methods for posting and such, my only issue is the user has to copy and paste the authentication code to get the token.
So my question is how can I get the authentication code if I use localhost as the redirect uri in C# or am I better off just forgetting trying to do this without using Google's .net Library
I ended up finding an answer over at Is it possible to use OAuth 2.0 without a redirect server? It is the last answer on the page, and it does retrieve the authorization code from the URL.
I have a AngularJS Web Application that requests data from API written in .NET Web API.
Now, I have ADFS 3.0 OAuth configured with my client ID and redirect URL(https://www.someredirecturl.index.html) utilizing Authorization Code Grant Flow.
I also have a .NET Web API that returns some values.
For e.g https://www.example.com/showData
Whenever, i call the URL, the ADFS Login screen shows up.
Then, the browser is redirected to my Redirect_URL with the authorization code. For e.g https://www.someredirecturl.index.html?code=xxxxxxxxx
Then, i capture the code and send it to the ADFS server( POST REQUEST ) to get the token.
Now, i have the token.
After this step, i should be able to call my API https://www.example.com/showData with Authorization Code: Bearer + token.
But, how does it work without writing anything at the server side.
Do i have to read the headers with key Authorization, extract the token?
What is the best way to do this?
At any point, will i see data on the browser directly, or it will always be called by some program sending headers.
What if www.example.com is a website. and www.example.com/api is a resource endpoint. How to merge the two of them. can user login to www.example.com when he would enter his credentials on ADFS. How to redirect from Redirect_URL with authorization code?
Yes - as per this.
Basically:
Check that the JWT is well formed
Check the signature
Validate the standard claims
Check the Client permissions (scopes)
jwt.io has a number of libraries that do this for you.
