Quickstart: Configure a client application to access web APIs

For a web/confidential client application to be able to participate in an authorization grant flow that requires authentication (and obtain an access token), it must establish secure credentials. The default authentication method supported by the Azure portal is client ID + secret key.

Additionally, before a client can access a web API exposed by a resource application (such as Microsoft Graph API), the consent framework ensures the client obtains the permission grant required based on the permissions requested. By default, all applications can choose permissions from the Microsoft Graph API. The Graph API “Sign-in and read user profile” permission is selected by default. You can select from two types of permissions for each desired web API:

  • Application permissions - Your client application needs to access the web API directly as itself (no user context). This type of permission requires administrator consent and is also not available for public (desktop and mobile) client applications.

  • Delegated permissions - Your client application needs to access the web API as the signed-in user, but with access limited by the selected permission. This type of permission can be granted by a user unless the permission requires administrator consent.


    Adding a delegated permission to an application does not automatically grant consent to the users within the tenant. Users must still manually consent for the added delegated permissions at runtime, unless the administrator grants consent on behalf of all users.

In this quickstart, we'll show you how to configure your app to:


To get started, make sure you complete these prerequisites:

Sign in to the Azure portal and select the app

Before you can configure the app, follow these steps:

  1. Sign in to the Azure portal using either a work or school account or a personal Microsoft account.
  2. If your account gives you access to more than one tenant, select your account in the top-right corner, and set your portal session to the desired Azure AD tenant.
  3. Search for and select Azure Active Directory.
  4. From the left pane, select App registrations.
  5. Find and select the application you want to configure. Once you've selected the app, you'll see the application's Overview or main registration page.
  6. Follow the steps to configure your application to access web APIs:

Add redirect URI(s) to your application

To add a redirect URI to your application:

  1. From the app's Overview page, select the Authentication section.

  2. To add a custom redirect URI for web and public client applications, follow these steps:

    1. Locate the Redirect URI section.
    2. Select the type of application you're building, Web or Public client (mobile & desktop).
    3. Enter the Redirect URI for your application.
      • For web applications, provide the base URL of your application. For example, http://localhost:31544 might be the URL for a web application running on your local machine. Users would use this URL to sign into a web client application.
      • For public applications, provide the URI used by Azure AD to return token responses. Enter a value specific to your application, for example: https://MyFirstApp.
  3. To choose from suggested Redirect URIs for public clients (mobile, desktop), follow these steps:

    1. Locate the Suggested Redirect URIs for public clients (mobile, desktop) section.
    2. Select the appropriate Redirect URI(s) for your application using the checkboxes. You can also enter a custom redirect URI. If you're not sure what to use, check out the library documentation.

There are certain restrictions that apply to redirect URIs. Learn more about redirect URI restrictions and limitations.


Try out the new Authentication settings experience where you can configure settings for your application based on the platform or device that you want to target.

To see this view, select Try out the new experience from the default Authentication page view.

Click "Try out the new experience" to see Platform configuration view

This takes you to the new Platform configurations page.

Configure advanced settings for your application

Depending on the application you're registering, there are some additional settings that you may need to configure, such as:

  • Logout URL
  • For single-page apps, you can enable Implicit grant and select the tokens that you'd like the authorization endpoint to issue.
  • For desktop apps that are acquiring tokens with Integrated Windows Authentication, device code flow, or username/password in the Default client type section, configure the Treat application as public client setting to Yes.
  • For legacy apps that were using the Live SDK to integrate with the Microsoft account service, configure Live SDK support. New apps don't need this setting.
  • Default client type

Modify supported account types

The Supported account types specify who can use the application or access the API.

Once you've configured the supported account types when you initially registered the application, you can only change this setting using the application manifest editor if:

  • You change account types from AzureADMyOrg or AzureADMultipleOrgs to AzureADandPersonalMicrosoftAccount, or vice versa.
  • You change account types from AzureADMyOrg to AzureADMultipleOrgs, or vice versa.

To change the supported account types for an existing app registration:

Configure platform settings for your application

Configure settings for your app based on the platform or device

To configure application settings based on the platform or device, you're targeting:

  1. In the Platform configurations page, select Add a platform and choose from the available options.

    Shows the Configure platforms page

  2. Enter the settings info based on the platform you selected.

    Platform Choices Configuration settings
    Web applications Web Enter the Redirect URI for your application.
    Mobile applications iOS Enter the app's Bundle ID, which you can find in XCode in Info.plist, or Build Settings. Adding the bundle ID automatically creates a redirect URI for the application.
    Android * Provide the app's Package name, which you can find in the AndroidManifest.xml file.
    * Generate and enter the Signature hash. Adding the signature hash automatically creates a redirect URI for the application.
    Desktop + devices Desktop + devices * Optional. Select one of the recommended Suggested redirect URIs if you're building apps for desktop and devices.
    * Optional. Enter a Custom redirect URI, which is used as the location where Azure AD will redirect users in response to authentication requests. For example, for .NET Core applications where you want interaction, use https://localhost.


    For mobile applications that aren't using the latest MSAL library or not using a broker, you must configure the redirect URIs for these applications in Desktop + devices.

  3. Depending on the platform you chose, there may be additional settings that you can configure. For Web apps, you can:

    • Add more redirect URIs
    • Configure Implicit grant to select the tokens you'd like to be issued by the authorization endpoint:
      • For single-page apps, select both Access tokens and ID tokens
      • For web apps, select ID tokens

Add credentials to your web application

To add a credential to your web application:

  1. From the app's Overview page, select the Certificates & secrets section.

  2. To add a certificate, follow these steps:

    1. Select Upload certificate.
    2. Select the file you'd like to upload. It must be one of the following file types: .cer, .pem, .crt.
    3. Select Add.
  3. To add a client secret, follow these steps:

    1. Select New client secret.
    2. Add a description for your client secret.
    3. Select a duration.
    4. Select Add.


After you save the configuration changes, the right-most column will contain the client secret value. Be sure to copy the value for use in your client application code as it's not accessible once you leave this page.

Add permissions to access web APIs

To add permission(s) to access resource APIs from your client:

  1. From the app's Overview page, select API permissions.
  2. Under the Configured permissions section, select the Add a permission button.
  3. By default, the view allows you to select from Microsoft APIs. Select the section of APIs that you're interested in:
    • Microsoft APIs - Lets you select permissions for Microsoft APIs such as Microsoft Graph.
    • APIs my organization uses - Lets you select permissions for APIs that have been exposed by your organization, or APIs that your organization has integrated with.
    • My APIs - Lets you select permissions for APIs that you have exposed.
  4. Once you've selected the APIs, you'll see the Request API Permissions page. If the API exposes both delegated and application permissions, select which type of permission your application needs.
  5. When finished, select Add permissions. You will return to the API permissions page, where the permissions have been saved and added to the table.

Configured permissions

This section shows the permissions that have been explicitly configured on the application object (\the permissions that are part of the app's required resource access list). You may add or remove permissions from this table. As an admin, you can also grant/revoke admin consent for a set of an API's permissions or individual permissions in this section.

Other permissions granted

If your application is registered in a tenant, you may see an additional section titled Other permissions granted for Tenant. This section shows permissions that have been granted for the tenant but have not been explicitly configured on the application object (e.g. permissions that were dynamically requested and consented). This section only appears if there is at least one permission that applies.

You may add a set of an API's permissions or individual permissions that appear in this section to the Configured permissions section. As an admin, you can also revoke admin consent for individual APIs or permissions in this section.

If your application is registered in a tenant, you will see a Grant admin consent for Tenant button. It will be disabled if you are not an admin, or if no permissions have been configured for the application. This button allows an admin to easily grant admin consent to the permissions configured for the application. Clicking the admin consent button launches a new window with a consent prompt showing all the configured permissions.


There is a delay between permissions being configured for the application and them appearing on the consent prompt. If you do not see all the configured permissions in the consent prompt, close it and launch it again.

If you have permissions that have been granted but not configured, when clicking the admin consent button you will be prompted to decide how to handle these permissions. You may add them to configured permissions or you may remove them.

The consent prompt provides the option to Accept or Cancel. If you select Accept, admin consent is granted. If you select Cancel, admin consent is not granted, and you will see an error stating that consent has been declined.


There is a delay between granting admin consent (selecting Accept on the consent prompt) and the status of admin consent being reflected in the UI.
