How can I insert a Workflow dynamically when an Order is placed in SAP Commerce Cloud [Hybris]?

I need to create a Workflow when an Order is placed and when the assigned user changes the Order attribute, it should trigger some business logic.

So far I have defined the Workflow template for Updating Order attribute, but unable to figure out how to dynamically create the Workflow when order is placed from storefront.

You can try overriding afterPlaceOrder method from DefaultCheckoutFacade, get the workflow template and trigger it from there

WorkflowTemplateService workflowTemplateService;
WorkflowService workflowService;
WorkflowTemplateService workflowTemplateService;

protected void afterPlaceOrder(final CartModel cartModel, final OrderModel orderModel)
{
    ........
    // get the workflow template
    final WorkflowTemplateModel workflowTemplate = workflowTemplateService
                .getWorkflowTemplateForCode(WFL_TEMPLATE_CODE);

    // create new workflow based on template
    final WorkflowModel workflow = workflowService.createWorkflow(workflowTemplate, attachment, user);

    // save the workflow
    modelService.save(workflow);

    // start the workflow
    workflowProcessingService.startWorkflow(workflow);
    ........
}
