### [Abblix\.SecurityEvents\.Delivery](https://www.abblix.com/en/docs/api/abblix-securityevents/Abblix.SecurityEvents.Delivery 'Abblix\.SecurityEvents\.Delivery')

## PollClient Class

The receiver's side of poll\-based delivery \(RFC 8936\): one POST that acknowledges what was
processed and asks for what waits\. The wire shapes live beside it; this type owns only the
transport\.

```csharp
public sealed class PollClient
```

Inheritance [System\.Object](https://learn.microsoft.com/en-us/dotnet/api/system.object 'System\.Object') → PollClient

### Remarks
It knows nothing of how the endpoint was learned\. RFC 8936 leaves that to whatever arranged
the feed, so a framework that carries poll deliveries in its own configuration \- Shared
Signals does \- adds the step from its model to this URL on its own side\.
### Constructors

## PollClient\(HttpClient\) Constructor {#Abblix.SecurityEvents.Delivery.PollClient.PollClient(System.Net.Http.HttpClient)}

The receiver's side of poll\-based delivery \(RFC 8936\): one POST that acknowledges what was
processed and asks for what waits\. The wire shapes live beside it; this type owns only the
transport\.

```csharp
public PollClient(System.Net.Http.HttpClient httpClient);
```
#### Parameters

###### `httpClient` [System\.Net\.Http\.HttpClient](https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpclient 'System\.Net\.Http\.HttpClient') {#Abblix.SecurityEvents.Delivery.PollClient.PollClient(System.Net.Http.HttpClient).httpClient}

The client polls are spoken through\. Authentication is its
            configuration, not this type's concern\.

### Remarks
It knows nothing of how the endpoint was learned\. RFC 8936 leaves that to whatever arranged
the feed, so a framework that carries poll deliveries in its own configuration \- Shared
Signals does \- adds the step from its model to this URL on its own side\.
