teams approvals with c#

[Bruno Sanz Marino]

Hello

Is there any way to work with teams approvals using Microsoft Graph API 1.0 and c#?

It looks like that thre is no api library support but

Can i use the http way? and whats the urls for that?

By example to create one request from the web application (back code)

Thank you

@Bruno Sanz Marino - Thanks for raising your query. 

There is no specific libraries for team approvals, you can indeed interact with the API using HTTP requests directly.

To create a request from your web application's backend code, you would typically follow these steps:

1. Authentication: Obtain an access token using the OAuth 2.0 authentication flow. You'll need to register your application in the Azure portal to get the necessary credentials.

2. Construct HTTP Request: Formulate an HTTP request to interact with the Microsoft Graph API. In this case, you'll want to use the appropriate endpoint for team approvals.

3. Send the Request: Use C#'s HttpClient class or any similar library to send the HTTP request.

4. Handle Response: Process the response from the Microsoft Graph API.

Here's a basic example of how you might create a request to create an approval request in a Microsoft Teams team using the Microsoft Graph API:

using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using Newtonsoft.Json;

public class Program
{
    private static readonly HttpClient httpClient = new HttpClient();
    private const string graphApiBaseUrl = "https://graph.microsoft.com/v1.0/";

    public static async Task Main(string[] args)
    {
        string accessToken = ""; // Your access token obtained after authentication

        // Construct the request payload
        var approvalRequest = new
        {
            templateId = "<template_id>",
            ... // Other properties as required by the API
        };

        string requestUrl = $"{graphApiBaseUrl}teams/{teamId}/approvals"; // Replace teamId with your actual team ID

        // Serialize the payload to JSON
        string jsonPayload = JsonConvert.SerializeObject(approvalRequest);

        // Create the HTTP request
        var request = new HttpRequestMessage(HttpMethod.Post, requestUrl);
        request.Headers.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Bearer", accessToken);
        request.Content = new StringContent(jsonPayload, Encoding.UTF8, "application/json");

        // Send the request and handle the response
        HttpResponseMessage response = await httpClient.SendAsync(request);

        if (response.IsSuccessStatusCode)
        {
            Console.WriteLine("Approval request created successfully!");
        }
        else
        {
            Console.WriteLine($"Error: {response.StatusCode} - {response.ReasonPhrase}");
        }
    }
}

Thanks,
