Microsoft Graph SDK for Go

Get started with the Microsoft Graph SDK for Go by integrating the Microsoft Graph API into your Go application!

Note: this SDK allows you to build applications using the v1.0 of Microsoft Graph. If you want to try the latest Microsoft Graph APIs under beta, use our beta SDK instead.

1. Installation

go get github.com/microsoftgraph/msgraph-sdk-go
go get github.com/microsoft/kiota-authentication-azure-go

2. Getting started

2.1 Register your application

Register your application by following the steps at Register your app with the Microsoft Identity Platform.

2.2 Create an AuthenticationProvider object

An instance of the GraphRequestAdapter class handles building client. To create a new instance of this class, you need to provide an instance of AuthenticationProvider, which can authenticate requests to Microsoft Graph.

For an example of how to get an authentication provider, see choose a Microsoft Graph authentication provider.

Note: we are working to add the getting started information for Go to our public documentation, in the meantime the following sample should help you getting started.

This example uses the DeviceCodeCredential class, which uses the device code flow to authenticate the user and acquire an access token. This authentication method is not enabled on app registrations by default. In order to use this example, you must enable public client flows on the app registation in the Azure portal by selecting Authentication under Manage, and setting the Allow public client flows toggle to Yes.

import (
    azidentity "github.com/Azure/azure-sdk-for-go/sdk/azidentity"
    "context"
)

cred, err := azidentity.NewDeviceCodeCredential(&azidentity.DeviceCodeCredentialOptions{
    TenantID: "<the tenant id from your app registration>",
    ClientID: "<the client id from your app registration>",
    UserPrompt: func(ctx context.Context, message azidentity.DeviceCodeMessage) error {
        fmt.Println(message.Message)
        return nil
    },
})

if err != nil {
    fmt.Printf("Error creating credentials: %v\n", err)
}

2.3 Get a Graph Service Client and Adapter object

You must get a GraphRequestAdapter object to make requests against the service.

import msgraphsdk "github.com/microsoftgraph/msgraph-sdk-go"

client , err  := msgraphsdk.NewGraphServiceClientWithCredentials(cred, []string{"Files.Read"})
if err != nil {
    fmt.Printf("Error creating client: %v\n", err)
    return
}

3. Make requests against the service

After you have a GraphServiceClient that is authenticated, you can begin making calls against the service. The requests against the service look like our REST API.

3.1 Get the user's drive

To retrieve the user's drive:

import (
    "github.com/microsoftgraph/msgraph-sdk-go/models/odataerrors"
)

result, err := client.Me().Drive().Get(context.Background(), nil)
if err != nil {
    fmt.Printf("Error getting the drive: %v\n", err)
    printOdataError(err)
}
fmt.Printf("Found Drive : %v\n", *result.GetId())

// omitted for brevity

func printOdataError(err error) {
	switch err.(type) {
	case *odataerrors.ODataError:
		typed := err.(*odataerrors.ODataError)
		fmt.Printf("error:", typed.Error())
		if terr := typed.GetErrorEscaped(); terr != nil {
			fmt.Printf("code: %s", *terr.GetCode())
			fmt.Printf("msg: %s", *terr.GetMessage())
		}
	default:
		fmt.Printf("%T > error: %#v", err, err)
	}
}

4. Getting results that span across multiple pages

Items in a collection response can span across multiple pages. To get the complete set of items in the collection, your application must make additional calls to get the subsequent pages until no more next link is provided in the response.

4.1 Get all the users in an environment

To retrieve the users:

import (
    msgraphcore "github.com/microsoftgraph/msgraph-sdk-go-core"
    "github.com/microsoftgraph/msgraph-sdk-go/users"
    "github.com/microsoftgraph/msgraph-sdk-go/models"
    "github.com/microsoftgraph/msgraph-sdk-go/models/odataerrors"
)

result, err := client.Users().Get(context.Background(), nil)
if err != nil {
    fmt.Printf("Error getting users: %v\n", err)
    printOdataError(err)
    return err
}

// Use PageIterator to iterate through all users
pageIterator, err := msgraphcore.NewPageIterator[models.Userable](result, client.GetAdapter(), models.CreateUserCollectionResponseFromDiscriminatorValue)

err = pageIterator.Iterate(context.Background(), func(user models.Userable) bool {
    fmt.Printf("%s\n", *user.GetDisplayName())
    // Return true to continue the iteration
    return true
})

// omitted for brevity

func printOdataError(err error) {
        switch err.(type) {
        case *odataerrors.ODataError:
                typed := err.(*odataerrors.ODataError)
                fmt.Printf("error: %s", typed.Error())
                if terr := typed.GetErrorEscaped(); terr != nil {
                        fmt.Printf("code: %s", *terr.GetCode())
                        fmt.Printf("msg: %s", *terr.GetMessage())
                }
        default:
                fmt.Printf("%T > error: %#v", err, err)
        }
}
