```
#### Parameters

#### Returns
[System\.Threading\.Tasks\.Task&lt;](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 'System\.Threading\.Tasks\.Task\`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.threading.tasks.task-1 'System\.Threading\.Tasks\.Task\`1')  
A task that resolves to the generated authorization code as a string\.

## AuthorizationCodeService\.RemoveAuthorizationCodeAsync\(string\) Method {#Abblix.Oidc.Server.Features.Storages.AuthorizationCodeService.RemoveAuthorizationCodeAsync(string)}

Atomically removes an authorization code from storage and returns the grant it held, in a
single get\-and\-remove operation\. This is how a code is claimed for redemption: it enforces
the single\-use guarantee against a race between two simultaneous redemptions of the same
code \(RFC 6749 §4\.1\.2\) — exactly one caller wins and receives the grant, every other caller
finds the code already gone and receives an `invalid_grant` failure\.

```csharp
public System.Threading.Tasks.Task<Abblix.Utils.Result<Abblix.Oidc.Server.Endpoints.Token.Interfaces.AuthorizedGrant,Abblix.Oidc.Server.Common.OidcError>> RemoveAuthorizationCodeAsync(string authorizationCode);
```
#### Parameters

###### `authorizationCode` [System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String') {#Abblix.Oidc.Server.Features.Storages.AuthorizationCodeService.RemoveAuthorizationCodeAsync(string).authorizationCode}

The authorization code to remove and claim\.

Implements [RemoveAuthorizationCodeAsync\(string\)](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Storages.IAuthorizationCodeService#Abblix.Oidc.Server.Features.Storages.IAuthorizationCodeService.RemoveAuthorizationCodeAsync(string) 'Abblix\.Oidc\.Server\.Features\.Storages\.IAuthorizationCodeService\.RemoveAuthorizationCodeAsync\(string\)')

#### Returns
[System\.Threading\.Tasks\.Task&lt;](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 'System\.Threading\.Tasks\.Task\`1')[Abblix\.Utils\.Result&lt;](https://learn.microsoft.com/en-us/dotnet/api/abblix.utils.result-2 'Abblix\.Utils\.Result\`2')[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')[,](https://learn.microsoft.com/en-us/dotnet/api/abblix.utils.result-2 'Abblix\.Utils\.Result\`2')[OidcError](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.OidcError 'Abblix\.Oidc\.Server\.Common\.OidcError')[&gt;](https://learn.microsoft.com/en-us/dotnet/api/abblix.utils.result-2 'Abblix\.Utils\.Result\`2')[&gt;](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 'System\.Threading\.Tasks\.Task\`1')  
The grant on success when this caller won the claim; an `invalid_grant`[OidcError](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.OidcError 'Abblix\.Oidc\.Server\.Common\.OidcError') when the code is absent — already claimed by a concurrent request,
already consumed, expired, or never issued\.

### Remarks
A successfully claimed grant whose `IssuedTokens` is non\-empty indicates the code was
already used to issue tokens \(a sequential reuse\), which the caller treats as a reuse to be
rejected and whose tokens are revoked\.

## AuthorizationCodeService\.UpdateAuthorizationGrantAsync\(string, AuthorizedGrant, TimeSpan\) Method {#Abblix.Oidc.Server.Features.Storages.AuthorizationCodeService.UpdateAuthorizationGrantAsync(string,Abblix.Oidc.Server.Endpoints.Token.Interfaces.AuthorizedGrant,System.TimeSpan)}

Updates the authorization grant result based on a specific authorization code and client information\.
This method allows the authorization grant to be updated with new information or tokens as needed\.

```csharp
public System.Threading.Tasks.Task UpdateAuthorizationGrantAsync(string authorizationCode, Abblix.Oidc.Server.Endpoints.Token.Interfaces.AuthorizedGrant authorizedGrant, System.TimeSpan authorizationCodeExpiresIn);
```
#### Parameters

###### `authorizationCode` [System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String') {#Abblix.Oidc.Server.Features.Storages.AuthorizationCodeService.UpdateAuthorizationGrantAsync(string,Abblix.Oidc.Server.Endpoints.Token.Interfaces.AuthorizedGrant,System.TimeSpan).authorizationCode}

            authentication and authorization details\.

Implements [UpdateAuthorizationGrantAsync\(string, AuthorizedGrant, TimeSpan\)](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Storages.IAuthorizationCodeService#Abblix.Oidc.Server.Features.Storages.IAuthorizationCodeService.UpdateAuthorizationGrantAsync(string,Abblix.Oidc.Server.Endpoints.Token.Interfaces.AuthorizedGrant,System.TimeSpan) 'Abblix\.Oidc\.Server\.Features\.Storages\.IAuthorizationCodeService\.UpdateAuthorizationGrantAsync\(string, Abblix\.Oidc\.Server\.Endpoints\.Token\.Interfaces\.AuthorizedGrant, System\.TimeSpan\)')
