## IClientRegistrationContextValidator Interface

One step in the client\-registration validation pipeline \(RFC 7591 §2 / OIDC DCR 1\.0\)\.
Implementations check a specific aspect of the supplied metadata \(redirect URIs,
grant types, signing algorithms, sector identifier, software statement, etc\.\) and
either clear it or surface an [OidcError](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.OidcError 'Abblix\.Oidc\.Server\.Common\.OidcError') for the response\.

### Methods

## IClientRegistrationContextValidator\.ValidateAsync\(ClientRegistrationValidationContext\) Method {#Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.IClientRegistrationContextValidator.ValidateAsync(Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.ClientRegistrationValidationContext)}

Validates the slice of registration metadata this implementation owns\.
May mutate [ClientRegistrationValidationContext](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.ClientRegistrationValidationContext 'Abblix\.Oidc\.Server\.Endpoints\.DynamicClientManagement\.Validation\.ClientRegistrationValidationContext') with derived values
\(for example the resolved sector identifier\)\.

```csharp
System.Threading.Tasks.Task<Abblix.Oidc.Server.Common.OidcError?> ValidateAsync(Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.ClientRegistrationValidationContext context);
```
#### Parameters

###### `context` [ClientRegistrationValidationContext](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.ClientRegistrationValidationContext 'Abblix\.Oidc\.Server\.Endpoints\.DynamicClientManagement\.Validation\.ClientRegistrationValidationContext') {#Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.IClientRegistrationContextValidator.ValidateAsync(Abblix.Oidc.Server.Endpoints.DynamicClientManagement.Validation.ClientRegistrationValidationContext).context}

The shared validation context for the current request\.
