+      When `content_type` contains a [MIME](https://en.wikipedia.org/wiki/Media_type) type, and `payload` is a string, its interpolated value will be sent as a string in the HTTP request's body and the request's `Content-Type` HTTP header will be set to `content_type`. When `payload` is a string `no_merge` has to be set to `true`.

       If `emit_events` is set to `true`, the server response will be emitted as an Event and can be fed to a WebsiteAgent for parsing (using its `data_from_event` and `type` options). No data processing

       will be attempted by this Agent, so the Event's "body" value will always be raw text.
