```csharp
public RequestObjectFetchAdapter(Abblix.Oidc.Server.Features.RequestObject.IRequestObjectFetcher requestObjectFetcher);
```
#### 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.Authorization.RequestFetching.RequestObjectFetchAdapter.RequestObjectFetchAdapter(Abblix.Oidc.Server.Features.RequestObject.IRequestObjectFetcher).requestObjectFetcher}

The request object fetcher responsible for fetching and processing
            the JWT request object\.
### Methods

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

Fetches and processes the authorization request by delegating to the request object fetcher\.
The request object JWT is validated and its claims are merged into the authorization request\.
Client identification is performed using the request parameter, JWT issuer claim, or JWT client\_id claim,
with validation ensuring all present sources match\.

```csharp
public System.Threading.Tasks.Task<Abblix.Utils.Result<Abblix.Oidc.Server.Model.AuthorizationRequest,Abblix.Oidc.Server.Endpoints.Authorization.Interfaces.AuthorizationRequestValidationError>> FetchAsync(Abblix.Oidc.Server.Model.AuthorizationRequest request);
```
#### Parameters

###### `request` [AuthorizationRequest](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model.AuthorizationRequest 'Abblix\.Oidc\.Server\.Model\.AuthorizationRequest') {#Abblix.Oidc.Server.Endpoints.Authorization.RequestFetching.RequestObjectFetchAdapter.FetchAsync(Abblix.Oidc.Server.Model.AuthorizationRequest).request}

The authorization request to be processed\.

Implements [FetchAsync\(AuthorizationRequest\)](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.Authorization.RequestFetching.IAuthorizationRequestFetcher#Abblix.Oidc.Server.Endpoints.Authorization.RequestFetching.IAuthorizationRequestFetcher.FetchAsync(Abblix.Oidc.Server.Model.AuthorizationRequest) 'Abblix\.Oidc\.Server\.Endpoints\.Authorization\.RequestFetching\.IAuthorizationRequestFetcher\.FetchAsync\(Abblix\.Oidc\.Server\.Model\.AuthorizationRequest\)')
