Response

A successful response will return the top-level provisioning with the meta field populated with the JSON sent in the POST:

{
  "name": "mystream",
  "scope": "live",
  "data": {
    "meta": <see above JSON>
  }
}

You can, as well, access this new provision at any time by making a GET request on the Stream Manager as such:
