## IUserInfoHandler Interface

Endpoint contract for the OpenID Connect UserInfo endpoint \(OIDC Core 1\.0 §5\.3\),
which returns claims about the authenticated end\-user identified by the bearer access
token presented per RFC 6750\.

```csharp
public interface IUserInfoHandler
```

Derived  
↳ [UserInfoHandler](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.UserInfo.UserInfoHandler 'Abblix\.Oidc\.Server\.Endpoints\.UserInfo\.UserInfoHandler')
### Methods

## IUserInfoHandler\.HandleAsync\(UserInfoRequest, ClientRequest\) Method {#Abblix.Oidc.Server.Endpoints.UserInfo.Interfaces.IUserInfoHandler.HandleAsync(Abblix.Oidc.Server.Model.UserInfoRequest,Abblix.Oidc.Server.Model.ClientRequest)}

Asynchronously handles a UserInfo request, validating the request for authorization and processing it to
return the requested user information\.

```csharp
System.Threading.Tasks.Task<Abblix.Utils.Result<Abblix.Oidc.Server.Endpoints.UserInfo.Interfaces.UserInfoFoundResponse,Abblix.Oidc.Server.Common.OidcError>> HandleAsync(Abblix.Oidc.Server.Model.UserInfoRequest userInfoRequest, Abblix.Oidc.Server.Model.ClientRequest clientRequest);
```
#### Parameters

###### `userInfoRequest` [UserInfoRequest](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model.UserInfoRequest 'Abblix\.Oidc\.Server\.Model\.UserInfoRequest') {#Abblix.Oidc.Server.Endpoints.UserInfo.Interfaces.IUserInfoHandler.HandleAsync(Abblix.Oidc.Server.Model.UserInfoRequest,Abblix.Oidc.Server.Model.ClientRequest).userInfoRequest}

The user info request containing the access token and possibly other parameters
            defining the scope of information requested\.

###### `clientRequest` [ClientRequest](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Model.ClientRequest 'Abblix\.Oidc\.Server\.Model\.ClientRequest') {#Abblix.Oidc.Server.Endpoints.UserInfo.Interfaces.IUserInfoHandler.HandleAsync(Abblix.Oidc.Server.Model.UserInfoRequest,Abblix.Oidc.Server.Model.ClientRequest).clientRequest}

Additional client\-specific request information that may be necessary for processing
            the request in certain contexts\.

#### Returns
[System\.Threading\.Tasks\.Task&lt;](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 'System\.Threading\.Tasks\.Task\`1')[Abblix\.Utils\.Result&lt;](https://learn.microsoft.com/en-us/dotnet/api/abblix.utils.result-2 'Abblix\.Utils\.Result\`2')[UserInfoFoundResponse](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Endpoints.UserInfo.Interfaces.UserInfoFoundResponse 'Abblix\.Oidc\.Server\.Endpoints\.UserInfo\.Interfaces\.UserInfoFoundResponse')[,](https://learn.microsoft.com/en-us/dotnet/api/abblix.utils.result-2 'Abblix\.Utils\.Result\`2')[OidcError](https://www.abblix.com/en/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Common.OidcError 'Abblix\.Oidc\.Server\.Common\.OidcError')[&gt;](https://learn.microsoft.com/en-us/dotnet/api/abblix.utils.result-2 'Abblix\.Utils\.Result\`2')[&gt;](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task-1 'System\.Threading\.Tasks\.Task\`1')  
A [System\.Threading\.Tasks\.Task](https://learn.microsoft.com/en-us/dotnet/api/system.threading.tasks.task 'System\.Threading\.Tasks\.Task') that resolves to a [Abblix\.Utils\.Result&lt;&gt;](https://learn.microsoft.com/en-us/dotnet/api/abblix.utils.result-2 'Abblix\.Utils\.Result\`2'),
which contains the user information if the request is authorized and valid,
or an error response indicating why the request could not be fulfilled\.

### Remarks
This method plays a crucial role in the OAuth 2\.0 and OIDC ecosystems by enabling secure access to user
information based on authorized requests\. Implementations should ensure that the access token provided
in the UserInfo request is validated and that any returned information is consistent with the scopes
granted during the authorization process\.
