+* body - the main contents. If HTTP is the protocol, this would be the request body.
 * call_id - the unique ID for the call.
 * content_type - format of the `body` parameter.
-* type - whether the call was sync or async.
 * deadline - a time limit for the call, based on function timeout.
 * protocol - arbitrary map of protocol specific data. The above example shows what the HTTP protocol handler passes in. Subject to change and reduces reusability of your functions. **USE AT YOUR OWN RISK**.
