### Methods

## RegisterClientHandler\.HandleAsync\(ClientRegistrationRequest\) Method {#Abblix.Oidc.Server.Endpoints.DynamicClientManagement.RegisterClientHandler.HandleAsync(Abblix.Oidc.Server.Model.ClientRegistrationRequest)}

Validates the registration metadata, then provisions the client and returns the
RFC 7591 §3\.2\.1 success response or an error per §3\.2\.2\.

```csharp
public System.Threading.Tasks.Task<Abblix.Utils.Result<Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Interfaces.ClientRegistrationSuccessResponse,Abblix.Oidc.Server.Common.OidcError>> HandleAsync(Abblix.Oidc.Server.Model.ClientRegistrationRequest clientRegistrationRequest);
