How can we pass additional parameters to the rest channel?

We have a custom rasa chatbot UI and wanted to pass an extra parameter (not slots or entities) to the API. Can we do something like this?

{
 "sender":"1234",
 "message":"hello",
 "param": "some value"
}

Hey @kirankrishnan, you can use the metadata for sending the additional parameter.
