-### Respond to an HTTP Event
-
-To respond to an HTTP event a function needs to return object with following fields:
-
-- `statusCode` - `int` - response status code, default: 200
-- `headers` - `object` - response headers
-- `body` - `string` - response body
-
-Currently, the event gateway supports only string responses.

 ### Invoking a Registered Function (Sync Function Invocation)
 
 `POST /` with `Event` header set to `invoke` and `Function-ID` set to function ID.
