DigitalTwinsClient.PublishTelemetry Method

Definition

Publishes telemetry from a digital twin synchronously. The result is then consumed by one or many destination endpoints (subscribers) defined under DigitalTwinsEventRoute. These event routes need to be set before publishing a telemetry message, in order for the telemetry message to be consumed.

public virtual Azure.Response PublishTelemetry (string digitalTwinId, string messageId, string payload, DateTimeOffset? timestamp = default, System.Threading.CancellationToken cancellationToken = default);
abstract member PublishTelemetry : string * string * string * Nullable<DateTimeOffset> * System.Threading.CancellationToken -> Azure.Response
override this.PublishTelemetry : string * string * string * Nullable<DateTimeOffset> * System.Threading.CancellationToken -> Azure.Response
Public Overridable Function PublishTelemetry (digitalTwinId As String, messageId As String, payload As String, Optional timestamp As Nullable(Of DateTimeOffset) = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Response
