Hello, I would like to easily push data into a temporal workflow on demand from another service. That said, is there a way to push data into an existing temporal workflow via REST api?

for example, if I had a simple workflow called `MyNameWorkflow` that accepts inputs `name:str` and returns `f"my name is: {name}"` using server `foo.tmprl.cloud:7233` via Temporal Cloud. Is there a method in which I could trigger that workflow via rest?

```auto
curl -X POST https://foo.tmprl.cloud:8080/api/workflows \
-H "Content-Type: application/json" \
-d '{
    "id": "my_workflow_id",
    "workflowType": "MyNameWorkflow",
    "taskQueue": "my-task-queue",
    "input": {
        "name": "John Smith"
    }
}'

```

if not, I can create my own service that executes processes like this via the python sdk. Just wanted to triple check prior to see if temporal supports this natively

Yes you can use openapi so dont have to write custom wrappers if you dont want to.  
You can see the openapi and swagger defs via:

http://\<frontend\_host\>:\<frontend\_http\_port\>/swagger.json  
http://\<frontend\_host\>:\<frontend\_http\_port\>/openapi.yaml

default http port is 7243: [temporal/docker/config\_template.yaml at main · temporalio/temporal · GitHub](https://github.com/temporalio/temporal/blob/main/docker/config_template.yaml#L271)

so your command to start new execution could be something like:

curl -X POST http://\<frontend\_host\>:\<frontend\_http\_port\>/api/v1/namespaces/default/workflows/fromopenapi -H “Content-Type: application/json” -d @mystartrequest.json

where mystartrequest.json could be something like:

```auto
{
  "namespace": "default",
  "workflowId": "my-workflow-id",
  "workflowType": {
    "name": "MyWorkflowType"
  },
  "taskQueue": {
    "name": "my-task-queue"
  },
  "input": {
    "payloads": [
      {
        "name": "john"
      }
    ]
  }
}

```

Hello! a quick question, Is this openapi/swagger support new? Any specific version I need to be on? I can’t find proper documentation around it- I found this [Serve OpenAPI v2 (swagger) and v3 HTTP docs by tdeebswihart · Pull Request #5393 · temporalio/temporal · GitHub](https://github.com/temporalio/temporal/pull/5393) where I have to enable `frontend.enableOpenAPIHTTPHandler` config- is this off by default? I can’t seem to get it working in my local temporal
