Internal Message Handler

Service Activator PHP

You're building a workflow step that processes a message but shouldn't be invokable from the Command Bus — for example, a "validate eligibility" step inside an Orchestrator, or a stage in an outputChannelName chain. An Internal Handler connects any service in your Dependency Container to a named input channel so it can play the role of an Endpoint, without exposing it as a Command Handler. If the service produces output, it can be connected to an output channel.

How to register

class Shop
{
    #[InternalHandler("buyProduct")] 
    public function buyProduct(int $productId) : void
    {
        echo "Product with id {$productId} was bought";
    }
}

Possible options

• endpointId - Endpoint identifier
• inputChannnelName - Required option, defines to which channel endpoint should be connected
• outputChannelName - Channel where result of method invocation will be
• requiredInterceptorNames - List of interceptor names, which should intercept the endpoint
