Getting null response using Alamofire

{
  "vUserList": [
    {
      "firstName": "Kate",
      "lastName": "Bell",
      "email": "[email protected]"
    },
    {
      "lastName": "Higgins",
      "firstName": "Daniel",
      "email": "[email protected]"
    },
    {
      "email": "[email protected]",
      "firstName": "John",
      "lastName": "Appleseed"
    },
    {
      "lastName": "Haro",
      "firstName": "Anna",
      "email": "[email protected]"
    },
    {
      "email": "[email protected]",
      "firstName": "Hank",
      "lastName": "Zakroff"
    }
  ]
}

This is the request parameters which I need to send to the server.

func getContactsParameters() -> [String : Any] {
        return [Keys.vUserList : arrContacts]
    }

var headers = [
                Keys.XAPIKEY: "5dik8fo5yecc25bfcc562724dd674bde5fh5ju8y"
            ]

Alamofire.request("urlString", method: .post, parameters: getContactsParameters(), encoding: JSONEncoding.default, headers: headers).responseJSON { response in
                print(response)
}

getContactsParameters() console log is as below, enter image description here In response, I am getting Null with the Success code.

I talked with backend people, they are saying, if I don't receive this key "vUserList" then you may get null response. But, I double-checked the spelling and everything. Another scenario is that, they are saying if we don't get request in proper json then you may get null response.

I tried many different solutions, none of them are working. :(

Any help is appreciated!

Here I am attaching, postman screenshot. In postman it is working fine. enter image description here

Try to pass the JSON string object of your contact array into your API params.

let arrOfUserList : [[String : AnyObject]] = [
            ["firstName":"Kate" as AnyObject,"lastName":"Bell" as AnyObject,"email":"[email protected]" as AnyObject],
            ["firstName":"Daniel" as AnyObject,"lastName":"Higgins" as AnyObject,"email":"[email protected]" as AnyObject]
        ]

do {
    let data = try JSONSerialization.data(withJSONObject: arrOfUserList, options: [])
    let jsonString = NSString(data: data, encoding: String.Encoding.utf8.rawValue)

     if jsonString != nil {

        let paramsContact = [Keys.vUserList : jsonString]

            //Do your API calling code here
     }
 } catch {
      print(error.localizedDescription)
 }

Hope it will work for you.

After Check your Postman

Please Add Header in your request 

let headers = [
    "Content-Type": "application/x-www-form-urlencoded"
]

If it doesn't work then

URLEncoding() or URLEncoding.httpBody or URLEncoding.default at the place of JSONEncoding.default
