Learn how to use virtual actors by calling HTTP/gRPC endpoints.
Invoke the actor method
You can interact with Dapr to invoke the actor method by calling HTTP/gRPC endpoint.
POST/GET/PUT/DELETE http://localhost:3500/v1.0/actors/<actorType>/<actorId>/method/<method>
Provide data for the actor method in the request body. The response for the request, which is data from actor method call, is in the response body.
Refer [to the Actors API spec]({{< ref "actors_api.md#invoke-actor-method" >}}) for more details.
{{% alert title="Note" color="primary" %}} Alternatively, you can use [Dapr SDKs to use actors]({{< ref "developing-applications/sdks/#sdk-languages" >}}). {{% /alert %}}
Save state with actors
You can interact with Dapr via HTTP/gRPC endpoints to save state reliably using the Dapr actor state management capabaility.
To use actors, your state store must support multi-item transactions. This means your state store component must implement the TransactionalStore interface.
[See the list of components that support transactions/actors]({{< ref supported-state-stores.md >}}). Only a single state store component can be used as the state store for all actors.
