## PingModeCompletionHandler Class

Handles CIBA ping mode token delivery where the client receives a notification that authentication is complete
and can then retrieve tokens from the token endpoint\.
In ping mode, the authenticated request is stored and a notification is sent to the client's registered endpoint\.

```csharp
public class PingModeCompletionHandler : Abblix.Oidc.Server.Features.BackChannelAuthentication.AuthenticationNotifiers.AuthenticationCompletionHandler
```

Logger for tracking notification events\.

Storage for authentication requests\.

Seals a session's subject the way the requesting client sees it,
            so the end user who authenticated can be compared against the one the request named\.

###### `notificationService` [INotificationDeliveryService](https://www.abblix.com/docs/api/abblix-oidc-server/Abblix.Oidc.Server.Features.BackChannelAuthentication.Interfaces.INotificationDeliveryService 'Abblix\.Oidc\.Server\.Features\.BackChannelAuthentication\.Interfaces\.INotificationDeliveryService') {#Abblix.Oidc.Server.Features.BackChannelAuthentication.AuthenticationNotifiers.PingModeCompletionHandler.PingModeCompletionHandler(Microsoft.Extensions.Logging.ILogger_Abblix.Oidc.Server.Features.BackChannelAuthentication.AuthenticationNotifiers.PingModeCompletionHandler_,Abblix.Oidc.Server.Features.BackChannelAuthentication.Interfaces.IBackChannelRequestStorage,Abblix.Oidc.Server.Features.PairwiseIdentifiers.ISubjectTypeConverter,Abblix.Oidc.Server.Features.BackChannelAuthentication.Interfaces.INotificationDeliveryService,Abblix.Oidc.Server.Features.BackChannelAuthentication.Interfaces.IBackChannelLongPollingService).notificationService}

Service for sending ping notifications\.

Wakes a client waiting on a long poll\. A ping client polls the token
            endpoint the same way a poll client does, and the long\-poll gate does not read the delivery mode \- so
            one that polls before its notification arrives waits, and is woken from here\.
