Start a workflow using the Dapr HTTP API with the workflow name, HelloWorldWorkflow, and an instance ID of 12345:
```bash
POST http://localhost:3500/v1.0-alpha1/workflows/dapr/HelloWorldWorkflow/12345/start
```
This results in a response that contains the workflow instance ID:
```bash
HTTP/1.1 202 Accepted
{
"instance_id": "12345"
}
```
Retrieve the workflow status and results with the HTTP API:
```bash
GET http://localhost:3500/v1.0-alpha1/workflows/dapr/HelloWorldWorkflow/12345
```
This results in a response that contains the workflow metadata:
```bash
HTTP/1.1 202 Accepted
{
"WFInfo": {
"instance_id": "12345"
},
"start_time": "2023-05-26T13:21:09Z",
"metadata": {
"dapr.workflow.custom_status": "",
"dapr.workflow.input": "\"World\"",
"dapr.workflow.last_updated": "2023-05-26T13:21:10Z",
"dapr.workflow.name": "HelloWorldWorkflow",
"dapr.workflow.output": "\"Hello World\"",
"dapr.workflow.runtime_status": "COMPLETED"
}
}
```
Some example scenarios that Dapr Workflow can perform are:
- Order processing involving orchestration between inventory management, payment systems, and shipping services.
