## IEndSessionRequestProcessor Interface

Performs the side\-effects of RP\-initiated logout once a request has been validated:
signs the end user out of the OP session, notifies every client that participated
in the session \(back\-channel and/or front\-channel logout\), and assembles the
post\-logout redirect target\.

```csharp
public interface IEndSessionRequestProcessor
```

### Methods

## IEndSessionRequestProcessor\.ProcessAsync\(ValidEndSessionRequest\) Method {#Abblix.Oidc.Server.Endpoints.EndSession.Interfaces.IEndSessionRequestProcessor.ProcessAsync(Abblix.Oidc.Server.Endpoints.EndSession.Interfaces.ValidEndSessionRequest)}

Executes logout for an already\-validated request\.
