Microsoft 365 Copilot APIs .NET Core Client Library

The Microsoft 365 Copilot APIs .NET Core Client Library contains core classes and interfaces used by the Microsoft 365 Copilot APIs Library to send native HTTP requests to the Microsoft 365 Copilot APIs. The latest core client library targets .NetStandard 2.0.

Note:

Because the Microsoft 365 Copilot APIs in the beta endpoint are subject to breaking changes, don't use a preview release of the client libraries in production apps.

Create a Copilot APIs client and make an API call

The following code example shows how to create an instance of a Microsoft 365 Copilot APIs client with an authentication provider in the supported languages. The authentication provider handles acquiring access tokens for the application. Many different authentication providers are available for each language and platform. The different authentication providers support different client scenarios. For details about which provider and options are appropriate for your scenario, see Choose an Authentication Provider.

The example also shows how to make a call to the Microsoft 365 Copilot Retrieval API. To call this API, you need to install the Microsoft 365 Copilot APIs .NET Beta Client Library, create a request object and then run the POST method on the request.

The client ID is the app registration ID that is generated when you register your app in the Azure portal.

Note:

Your tenant must have a Microsoft 365 Copilot license.

using Azure.Identity;
using Microsoft.Agents.M365Copilot.Beta;
using Microsoft.Agents.M365Copilot.Beta.Models;

var scopes = new[] {"Files.Read.All", "Sites.Read.All"}; 
 
// Multi-tenant apps can use "common", 
// single-tenant apps must use the tenant ID from the Azure portal 
var tenantId = "YOUR_TENANT_ID"; 
 
// Value from app registration 
var clientId = "YOUR_CLIENT_ID"; 
 
// using Azure.Identity; 
var deviceCodeCredentialOptions = new DeviceCodeCredentialOptions 
{ 
   ClientId = clientId, 
   TenantId = tenantId, 
   // Callback function that receives the user prompt 
   // Prompt contains the generated device code that user must 
   // enter during the auth process in the browser 
   DeviceCodeCallback = (deviceCodeInfo, cancellationToken) => 
   { 
       Console.WriteLine(deviceCodeInfo.Message); 
       return Task.CompletedTask; 
   }, 
}; 
 
// https://learn.microsoft.com/dotnet/api/azure.identity.devicecodecredential 
var deviceCodeCredential = new DeviceCodeCredential(deviceCodeCredentialOptions); 

//Create the client with explicit base URL 
var baseURL = “https://graph.microsoft.com/beta”; 
AgentsM365CopilotBetaServiceClient client = new AgentsM365CopilotBetaServiceClient (deviceCodeCredential, scopes, baseURL);
