## SessionEstablishedPayload Class

Session Established \(CAEP 1\.0 Section 3\.6\): the transmitter established a new session for
the subject \- how a service closes the loop with the identity provider after federation, how
an identity provider detects unintended logins, how a receiver inventories sessions\. The
[EventTimestamp](https://www.abblix.com/en/docs/api/abblix-securityevents-caep/Abblix.SecurityEvents.CAEP.CaepEventPayload#Abblix.SecurityEvents.CAEP.CaepEventPayload.EventTimestamp 'Abblix\.SecurityEvents\.CAEP\.CaepEventPayload\.EventTimestamp') is the moment the session was established\.

```csharp
public sealed record SessionEstablishedPayload : Abblix.SecurityEvents.CAEP.CaepEventPayload, System.IEquatable<Abblix.SecurityEvents.CAEP.SessionEstablishedPayload>
