## AuthorizationCodeGrantHandler Class

[IAuthorizationGrantHandler](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Token.Grants.IAuthorizationGrantHandler 'Abblix\.Oidc\.Server\.Endpoints\.Token\.Grants\.IAuthorizationGrantHandler') for `grant_type=authorization_code` \(RFC 6749 §4\.1\.3\)\.
            Resolves the code to its stored [AuthorizedGrant](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Token.Interfaces.AuthorizedGrant 'Abblix\.Oidc\.Server\.Endpoints\.Token\.Interfaces\.AuthorizedGrant'), asserts that the redeeming client is
            the same one the code was issued to, and, when a `code_challenge` was bound at the authorization
            request, runs the RFC 7636 §4\.6 verification by transforming the submitted `code_verifier` with
            the recorded `plain` / `S256` / `S512` method\.

```csharp
public class AuthorizationCodeGrantHandler : Abblix.Oidc.Server.Endpoints.Token.Grants.IAuthorizationGrantHandler, Abblix.Oidc.Server.Common.Interfaces.IGrantTypeInformer

```
#### Parameters

###### `authorizationCodeService` [IAuthorizationCodeService](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Storages.IAuthorizationCodeService 'Abblix\.Oidc\.Server\.Features\.Storages\.IAuthorizationCodeService') {#Abblix.Oidc.Server.Endpoints.Token.Grants.AuthorizationCodeGrantHandler.AuthorizationCodeGrantHandler(Abblix.Oidc.Server.Features.Storages.IAuthorizationCodeService).authorizationCodeService}

Persists, looks up and removes authorization codes\.
### Properties

## AuthorizationCodeGrantHandler\.GrantTypesSupported Property {#Abblix.Oidc.Server.Endpoints.Token.Grants.AuthorizationCodeGrantHandler.GrantTypesSupported}

Provides the grant type this handler supports, which is the OAuth 2\.0 'authorization\_code' grant type\.
This information is useful for identifying the handler's capabilities in a broader authorization framework\.

```csharp
public System.Collections.Generic.IEnumerable<string> GrantTypesSupported { get; }
```

Implements [GrantTypesSupported](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.Interfaces.IGrantTypeInformer#Abblix.Oidc.Server.Common.Interfaces.IGrantTypeInformer.GrantTypesSupported 'Abblix\.Oidc\.Server\.Common\.Interfaces\.IGrantTypeInformer\.GrantTypesSupported')

#### Property Value
[System\.Collections\.Generic\.IEnumerable&lt;](https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.ienumerable-1 'System\.Collections\.Generic\.IEnumerable\`1')[System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String')[&gt;](https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.ienumerable-1 'System\.Collections\.Generic\.IEnumerable\`1')
### Methods

## AuthorizationCodeGrantHandler\.AuthorizeAsync\(TokenRequest, ClientInfo\) Method {#Abblix.Oidc.Server.Endpoints.Token.Grants.AuthorizationCodeGrantHandler.AuthorizeAsync(Abblix.Oidc.Server.Model.TokenRequest,Abblix.Oidc.Server.Features.ClientInformation.ClientInfo)}

Authorizes a token request asynchronously using the authorization code grant type\.
This method validates the authorization code submitted by the client, ensures the client making the request
is the same as the one to whom the code was originally issued, and performs any necessary PKCE checks\.
It ensures that all security requirements, including client verification and PKCE validation, are enforced
before tokens are issued\.

```csharp
public System.Threading.Tasks.Task<Abblix.Utils.Result<Abblix.Oidc.Server.Endpoints.Token.Interfaces.AuthorizedGrant,Abblix.Oidc.Server.Common.OidcError>> AuthorizeAsync(Abblix.Oidc.Server.Model.TokenRequest request, Abblix.Oidc.Server.Features.ClientInformation.ClientInfo clientInfo);
```
#### Parameters

###### `request` [TokenRequest](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model.TokenRequest 'Abblix\.Oidc\.Server\.Model\.TokenRequest') {#Abblix.Oidc.Server.Endpoints.Token.Grants.AuthorizationCodeGrantHandler.AuthorizeAsync(Abblix.Oidc.Server.Model.TokenRequest,Abblix.Oidc.Server.Features.ClientInformation.ClientInfo).request}

The token request containing the authorization code and other necessary parameters\.

###### `clientInfo` [ClientInfo](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.ClientInformation.ClientInfo 'Abblix\.Oidc\.Server\.Features\.ClientInformation\.ClientInfo') {#Abblix.Oidc.Server.Endpoints.Token.Grants.AuthorizationCodeGrantHandler.AuthorizeAsync(Abblix.Oidc.Server.Model.TokenRequest,Abblix.Oidc.Server.Features.ClientInformation.ClientInfo).clientInfo}

Information about the client, used to verify that the request is valid for this client\.

Implements [AuthorizeAsync\(TokenRequest, ClientInfo\)](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Token.Grants.IAuthorizationGrantHandler#Abblix.Oidc.Server.Endpoints.Token.Grants.IAuthorizationGrantHandler.AuthorizeAsync(Abblix.Oidc.Server.Model.TokenRequest,Abblix.Oidc.Server.Features.ClientInformation.ClientInfo) 'Abblix\.Oidc\.Server\.Endpoints\.Token\.Grants\.IAuthorizationGrantHandler\.AuthorizeAsync\(Abblix\.Oidc\.Server\.Model\.TokenRequest, Abblix\.Oidc\.Server\.Features\.ClientInformation\.ClientInfo\)')

A task that represents the asynchronous authorization operation\.
            The result is either an authorized grant or an error indicating why the request failed\.
