## IdTokenResponseBuilder Class

Builds the `id_token` response\-type component of an authorization endpoint success
response — the OIDC identity\-token contributor of the Implicit / Hybrid Flow\. Generates
an ID token via [IIdentityTokenService](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.Tokens.IIdentityTokenService 'Abblix\.Oidc\.Server\.Features\.Tokens\.IIdentityTokenService') and stores it on the running
[SuccessfullyAuthenticated](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Authorization.Interfaces.SuccessfullyAuthenticated 'Abblix\.Oidc\.Server\.Endpoints\.Authorization\.Interfaces\.SuccessfullyAuthenticated') result\. Registered ONLY when a host calls
`EnableImplicitFlow()`; absent by default per OAuth 2\.1 \(draft\) deprecation guidance\.
Declares `implicit` in [GrantTypesSupported](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.ImplicitFlow.IdTokenResponseBuilder#Abblix.Oidc.Server.Features.ImplicitFlow.IdTokenResponseBuilder.GrantTypesSupported 'Abblix\.Oidc\.Server\.Features\.ImplicitFlow\.IdTokenResponseBuilder\.GrantTypesSupported') so opting in surfaces the
implicit grant in discovery and registration\-time gating without extra DI wiring\.

```csharp
public class IdTokenResponseBuilder : Abblix.Oidc.Server.Endpoints.Authorization.Interfaces.IAuthorizationResponseBuilder, Abblix.Oidc.Server.Common.Interfaces.IGrantTypeInformer

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → IdTokenResponseBuilder

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

### Remarks
This builder is order\-dependent: it reads [Code](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Authorization.Interfaces.SuccessfullyAuthenticated#Abblix.Oidc.Server.Endpoints.Authorization.Interfaces.SuccessfullyAuthenticated.Code 'Abblix\.Oidc\.Server\.Endpoints\.Authorization\.Interfaces\.SuccessfullyAuthenticated\.Code')
and [AccessToken](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Authorization.Interfaces.SuccessfullyAuthenticated#Abblix.Oidc.Server.Endpoints.Authorization.Interfaces.SuccessfullyAuthenticated.AccessToken 'Abblix\.Oidc\.Server\.Endpoints\.Authorization\.Interfaces\.SuccessfullyAuthenticated\.AccessToken') populated by earlier builders to
compute the `c_hash` and `at_hash` claims when those response components are
present\. The orchestrator iterates response\-type parts in canonical order \(`code` →
`token` → `id_token`\) so this dependency holds without explicit sequencing on
the builder side\.
