## UpdateClientRequestValidator Class

Validates an RFC 7592 §2\.2 update request: authenticates the registration access token and
confirms the client exists, then validates the supplied replacement metadata via the
update\-specific keyed [IRegisterClientRequestValidator](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Interfaces.IRegisterClientRequestValidator 'Abblix\.Oidc\.Server\.Endpoints\.DynamicClientManagement\.Interfaces\.IRegisterClientRequestValidator')\. Also enforces the
RFC 7592 §2\.2 rule that the request body's `client_id` must match the authenticated client\.

```csharp
public class UpdateClientRequestValidator : Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Interfaces.IUpdateClientRequestValidator
```
