Authorization Code Grant Flow

 

Updated: September 16, 2015

Access to web APIs by native clients and websites in Azure Active Directory (Azure AD) is implemented by using the OAuth 2.0 Authorization Code Grant flow. In this flow, the user delegates access to a client application. The transaction is protected and mediated by a code grant, which is exchanged for an access token. The client application never sees the user's credentials and the user agent never sees the access token.

The standard Authorization Code Grant flow is described in Section 4.1 of the The OAuth 2.0 Authorization FrameworkThis diagram shows how the Authorization Code Grant Flow works in Azure AD.

The following diagram illustrates the Authorization Code Grant flow.

Authorization Code Flow diagram
  1. The client application starts the flow by redirecting the user agent to the Azure AD authorization endpoint. The user authenticates and consents, if consent is required.

  2. The Azure AD authorization endpoint redirects the user agent back to the client application with an authorization code. The user agent returns authorization code to the client application’s redirect URI.

  3. The client application requests an access token from the Azure AD token issuance endpoint. It presents the authorization code to prove that the user has consented.

  4. The Azure AD token issuance endpoint returns an access token and a refresh token. The refresh token can be used to request additional access tokens.

  5. The client application uses the access token to authenticate to the Web API.

  6. After authenticating the client application, the web API returns the requested data.

To begin, use the Azure Management Portal to register the application in your Azure AD tenant. For detailed instructions, see Adding, Updating, and Removing an App

Next, the application prompts the user to authenticate to Azure AD and to allow Azure AD to release an authorization code to the application. The application presents the authorization code to an authorization server and the authorization server returns an access token that gives the application permission to access the resource.

To get the authorization code, the web browser (or an embedded web browser control) navigates to a tenant-specific or common (tenant-independent) endpoint.

: https://login.microsoftonline.com/common/oauth2/authorize
-or-
: https://login.microsoftonline.com/<tenant id>/oauth2/authorize
System_CAPS_noteNote

If the user is part of an organization, an administrator of the organization can consent or decline on the user's behalf, or permit the user to consent. The user is given the option to consent only when the administrator permits it.

To request an authorization code for access to a resource, create an OAuth 2.0 GET request, like this one:

GET /common/oauth2/authorize? response_type=code&client_id=<client_ID>&redirect_uri=<redirect_uri>

For example:

GET /common/oauth2/authorize?response_type=code&client_id=2d4d11a2-f814-46a7-890a-274a72a7309e&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F

The following table describes the valid parameters in the request.

Parameter

Description

client_id

[Required] Specifies the client id of the application that is registered in Azure Active Directory.

To find the application's client ID, in the Azure Management Portal, click Active Directory, click the directory, click the application and then click Configure.

domain_hint

[Optional] Provides a hint about the tenant or domain that the user should use to sign in. The value of the domain_hint is a registered domain for the tenant. If the tenant is federated to an on-premises directory, AAD redirects to the specified tenant federation server.

login_hint

[Optional] Provides a hint to the user on the sign-in page. For example, this value is pre-filled in the username field on the sign-in page.

prompt

[Optional] Indicate the type of user interaction that is required.

Valid values are:

-- login: The user should be prompted to re-authenticate.-- consent: User consent has been granted, but needs to be updated. The user should be prompted to consent. -- admin_consent: An administrator should be prompted to consent on behalf of all users in their organization.

redirect_uri

[Recommended] Specifies the reply URL of the application.

To find the application's reply URL, in the Azure Management Portal, click Active Directory, click the directory, and then click the application and then click Configure. The Reply URL field is in the Single Sign-on section of the Configure page.

resource

[Optional] The App ID URI of the web API (secured resource).

To find the App ID URI of the web API, in the Azure Management Portal, click Active Directory, click the directory, click the application and then click Configure.

response_type

[Required] Specifies the requested response type. In an authorization code grant request, the value must be code.

state

[Recommended] A randomly generated non-reused value that is sent in the request and returned in the response. This parameter is used as a mitigation against cross-site request forgery (CSRF) attacks. For more information, see Best Practices for OAuth 2.0 in Azure AD.

Examples

The following are examples of valid GET requests for an authorization code.

In this request, the application with client_id 2d4d11a2-f814-46a7-890a-274a72a7309e requests an authorization code. The authorization code will be used to request a token for the web API with the resource identifierhttps://service.contoso.com/. Because the expected user is admin@contoso.com, this value used in a login_hint that is prefilled in username field on the sign-in page. The redirect_uri value in the request is the registered redirect URI for the application. When the application runs on the user’s device and is not hosted on a website, the redirect URI does not need to be a physical endpoint.

GET 
/common/oauth2/authorize? response_type=code&client_id=2d4d11a2-f814-46a7-890a-274a72a7309e&resource=https%3A%2F%2Fservice.contoso.com%2F&redirect_uri=http%3A%2F%2Flocalhost/myapp%2F&state=D79E5777-702E-4260-9A62-37F75FF22CCE&login_hint=admin%40contoso.com

The following example is similar to the previous one, but it uses the domain_hint parameter to suggest a domain and the prompt parameter to specify a consent prompt.

GET 
/common/oauth2/authorize?response_type=code&client_id=2d4d11a2-f814-46a7-890a-274a72a7309e&resource=https%3A%2F%2Fservice.contoso.com%2F&redirect_uri=http%3A%2F%2Flocalhost/myapp%2F&state=D79E5777-702E-4260-9A62-37F75FF22CCE&domain_hint=contoso.com&prompt=login

When an application sends a GET request for an authorization code, Azure AD sends a response to the value of the redirect_uri parameter in the request. The response includes the following parameters.

Parameter

Description

admin_consent

The value is True if an administrator consented to a consent request prompt.

code

The authorization code that the application requested. The application can use the authorization code to request an access token for the target resource.

session_state

A unique value that identifies the current user session. This value is a GUID, but should be treated as an opaque value that is passed without examination.

state

If a state parameter is included in the request, the same value should appear in the response. The application should verify that the state values in the request and response are identical. For more information, see Best Practices for OAuth 2.0 in Azure AD.

The following is a sample response to an authorization code request.

The location header value matches the redirect_uri value in the request. If the state value in the response matches the state value in the request, the application should store the authorization code for use in the access token request.

GET  HTTP/1.1 302 Found
Location: http://localhost/myapp/?code= AwABAAAAvPM1KaPlrEqdFSBzjqfTGBCmLdgfSTLEMPGYuNHSUYBrqqf_ZT_p5uEAEJJ_nZ3UmphWygRNy2C3jJ239gV_DBnZ2syeg95Ki-374WHUP-i3yIhv5i-7KU2CEoPXwURQp6IVYMw-DjAOzn7C3JCu5wpngXmbZKtJdWmiBzHpcO2aICJPu1KvJrDLDP20chJBXzVYJtkfjviLNNW7l7Y3ydcHDsBRKZc3GuMQanmcghXPyoDg41g8XbwPudVh7uCmUponBQpIhbuffFP_tbV8SNzsPoFz9CLpBCZagJVXeqWoYMPe2dSsPiLO9Alf_YIe5zpi-zY4C3aLw5g9at35eZTfNd0gBRpR5ojkMIcZZ6IgAA&session_state=7B29111D-C220-4263-99AB-6F6E135D75EF&state=D79E5777-702E-4260-9A62-37F75FF22CCE

When the application gets the authorization code from the authorization endpoint, it can use the authorization code to request an access token from Azure AD.

To redeem an authorization code and get an access token, sent an HTTP POST request to a common or tenant-specific Azure AD Authorization endpoint.

: https://login.microsoftonline.com/common/oauth2/token
or
: https://login.microsoftonline.com/<tenant id>/oauth2/token

You can use the access token that is returned in the response to authenticate to a protected resources, such as a web API. Typically, the token is presented to the web API in an HTTP request using the Bearer scheme, which is described in RFC 6750. This specification explains how to use bearer tokens in HTTP requests to access protected resources.

When the web API receives and validates the token, it gives the native client application access to the web API.

The following example shows a GET request that passes an access token in the request body. The Authorization header indicates that it is a bearer token, which is valid for anyone who possesses the token.

When an access token expires, the native client application can use the refresh token to get a new access token. The lifetime of the refresh token is not provided and varies based on policy settings and the time when the authorization code grant is revoked by Azure AD. The application should expect and handle cases when the request for a new access token fails. In that case, it should return to the code that requests a new access token. For details, see Best Practices for OAuth 2.0 in Azure AD.

To use a refresh token to request a new access token, use an HTTP POST request to the common (tenant-independent) or a tenant-specific Azure AD endpoint.

: https://login.microsoftonline.com/common/oauth2/token
-or-
: https://login.microsoftonline.com/<tenant id>/oauth2/token

Use the following parameters in a token request that includes a refresh token.

Parameter

Description

client_id

[Optional] The client ID of the native client application that is registered in Azure AD.

To find the application's client ID, in the Azure Management Portal, click Active Directory, click the directory, click the application, and then click Configure.

client_secret

[Required for confidential clients (websites)] Contains the client password.

grant_type

[Required] Indicates the type of grant being used. In this case, the value must be refresh_token.

refresh_token

[Required] The refresh token that was included in the response that provided the access token.

resource

[Optional] The App ID URI of the web API (secured resource).

To find the App ID URI, in the Azure Management Portal, click Active Directory, click the directory, click the application, and then click Configure.

Examples

The following example uses a refresh_token to request a new access token. The POST includes the required grant_type and refresh_token parameters, but none of the optional parameters. Typically, this format is used when the original request specified the resource and there's no need to include it again.
