## RequestObjectFetchAdapter Class

Adapts the generic [IRequestObjectFetcher](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.RequestObject.IRequestObjectFetcher 'Abblix\.Oidc\.Server\.Features\.RequestObject\.IRequestObjectFetcher') \(signed\-JWT Request Object handling\) to the
CIBA\-specific [IBackChannelAuthenticationRequestFetcher](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.BackChannelAuthentication.RequestFetching.IBackChannelAuthenticationRequestFetcher 'Abblix\.Oidc\.Server\.Endpoints\.BackChannelAuthentication\.RequestFetching\.IBackChannelAuthenticationRequestFetcher') contract, passing the request's
`request` parameter through unchanged for JWT validation and parameter merging\.

```csharp
public class RequestObjectFetchAdapter : Abblix.Oidc.Server.Endpoints.BackChannelAuthentication.RequestFetching.IBackChannelAuthenticationRequestFetcher
```

#### Parameters

###### `requestObjectFetcher` [IRequestObjectFetcher](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.RequestObject.IRequestObjectFetcher 'Abblix\.Oidc\.Server\.Features\.RequestObject\.IRequestObjectFetcher') {#Abblix.Oidc.Server.Endpoints.BackChannelAuthentication.RequestFetching.RequestObjectFetchAdapter.RequestObjectFetchAdapter(Abblix.Oidc.Server.Features.RequestObject.IRequestObjectFetcher).requestObjectFetcher}

            outer request model\.
### Methods

## RequestObjectFetchAdapter\.FetchAsync\(BackChannelAuthenticationRequest\) Method {#Abblix.Oidc.Server.Endpoints.BackChannelAuthentication.RequestFetching.RequestObjectFetchAdapter.FetchAsync(Abblix.Oidc.Server.Model.BackChannelAuthenticationRequest)}

Delegates to the underlying request\-object fetcher, passing `request.Request` as the JWT to
be validated and merged into the outer model\.

```csharp
public System.Threading.Tasks.Task<Abblix.Utils.Result<Abblix.Oidc.Server.Model.BackChannelAuthenticationRequest,Abblix.Oidc.Server.Common.OidcError>> FetchAsync(Abblix.Oidc.Server.Model.BackChannelAuthenticationRequest request);
```
#### Parameters
