How to send a personalized message to rasa

Hello rasa team,

I am a beginner on rasa and I want to send a personalized message to rasa like this one :

{
"body": {
    "messageError": "",
    "request": "my request",
    "response": "the response"
},
"header": {
    "channelSource": "FRONT",
    "requestType": "TEXT",
    "responseType": "",
    "returnCode": "",
    "senderID": "id897",
    "webSocketSenderID": "id1"
}
}

I use the api : /webhooks/rest/webhook/

please is there a way to send such a message to rasa and he can understand it and send me a reply with the same object ?
