In your solution directory, there's a folder called test. In the test folder, you'll find *.HttpApi.Client.ConsoleTestApp project. This project is a sample console application that logins to the backend and makes an authenticated API call. To be able to run this project, run the following projects

*.HttpApi.Host
*.IdentityServer

Configure your host credentials in the appsettings.json of this console application:

Run in debug, to make a request for fetching all users. (it's an authenticated request and adds bearer token automatically)

If you want to manually build your own API client you can follow the IDS4 documentation: https://identityserver4.readthedocs.io/en/latest/quickstarts/1_client_credentials.html#creating-the-client

On the other hand, you can also check out the ABP CLI code as an example. It authenticates to the backend and make API calls.

Login => https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.Cli.Core/Volo/Abp/Cli/Commands/LoginCommand.cs#L51
Set Bearer token => https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.Cli.Core/Volo/Abp/Cli/Http/CliHttpClient.cs#L48
Make a remote service all => https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.Cli.Core/Volo/Abp/Cli/Commands/Services/AbpNuGetIndexUrlService.cs#L22

Hello Alper, Thanks but as i am new in ABP and Identity so i am confused. I am providing basic details: 1- Login using microsoft authtentication as per screen shot:

       2- Received auth token in angular UI           
       3- Call ABP custom api (workflowAPI to give the name)
       4- Pass auth token to calling api in header as "Authorization"
       5- Get the auth token in ABP workflowAPI api as below code:

    
           Declare in class:
           private readonly IHttpContextAccessor _httpContextAccessor;
           
           Within Method:
           var accessToken = _httpContextAccessor.HttpContext.Request.Headers["Authorization"];
           
            var client = new RestClient(url);           
            client.AddDefaultHeader("Authorization", accessToken);
            client.AddDefaultHeader("Content-Type", "application/json");
            client.AddDefaultHeader("Accept", "application/json");
            
            RestRequest restRequest = new RestRequest();

            var response = client.Execute<T>(restRequest);

        Error:
        "Unauthorized"
        
        Reason:
        "accessToken" is an  ABP identity server auth token not the Microsoft access token.
        
        
        Help Required:
        How to get the microsoft access token in my method. Can you give me step by step details.

Hi Maliming, Ok. Scenario is: 1- User login using microsoft account (Done) 2- User view menu (Done) as per permission 3- User have one menu option "Workflow service". 4- User clicks the "workflow service" menu 5- Backend API "WorkflowserviceList" get triggered 6- Within "WorkflowserviceList" a microsoft api i.e. (GetWorkflowInstances) is called 7- To call microsoft api "GetWorkflowInstances", caller should pass microsoft access token

              ABP API: 
              
              Public WorkflowserviceList()
              {
                         Call microsoft API GetWorkflowInstances(Access Token);                             
              }
              
              Access token should be of the same user who has logged in.
              
              I hope i am clear now.

We can't provide much help on the question of calling Microsoft APIs. I recommend that you check Microsoft's document. : )
