I am using `Azure Functions` and I have a third party `API` I want to call. I have the URL to it but it is a `POST` method so I know to use a "post" for `method type` and also I know about the that I can create a `class` and pass the values in there as a `class object`.
But what if the BODY sample they need is more complex. In my case something like this below.
In that case do I still create a `class`? **How** should I model it when it more complex like this?

```
 {
    "familyHierarchy": {
        "familyMembers": {
            "memberIds": ["string"],
            "age": 0,
            "marriageDate": "string"
        },
        "familyGroup": "string"
    },
    "pageSize": 0
}

```

**Also** here is what currently I have for my **method signature** but not sure about `FromBody` that I am asking about

```
[FunctionName("GetFamilyInfo")]
public static async Task<IActionResult> GetFamilyInfo([HttpTrigger(AuthorizationLevel.Function, "post", Route = "families/")] HttpRequest req, ILogger log)

```
