Hello I'm trying to translate POST request api code written in php:

<?php
$methodParams = '{
    "date_confirmed_from": 1407341754,
    "get_unconfirmed_orders": false
}';
$apiParams = [
    "method" => "getOrders",
    "parameters" => $methodParams
];

$curl = curl_init("https://api.baselinker.com/connector.php");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_HTTPHEADER, ["X-BLToken: xxx"]);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($apiParams));
$response = curl_exec($curl);

To Swift but I don't have idea why it doesn't work:

import UIKit

struct Parameters: Codable {
    let date_confirmed_from: Int
    let get_unconfirmed_orders: Bool
}

struct BodyData: Codable {
    let method: String
    let parameters:Parameters
}

let url = URL(string: "https://api.baselinker.com/connector.php")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.allHTTPHeaderFields = [
    "X-BLToken": "xxx"
]

let bodyData = BodyData(method: "getOrders", parameters: Parameters(date_confirmed_from: 1407341754, get_unconfirmed_orders: false))
let encoder = JSONEncoder()
do {
    let encodeData = try encoder.encode(bodyData)
    request.httpBody = encodeData
    let session = URLSession(configuration: .default)
    let task = session.dataTask(with: request) { (data, response, error) in
        if let error = error {
            print(error)
        }
        if  let data = data {

        }
    }
    task.resume()
    
    
}catch {
    print(error)
}

When I'm testing my Swift code I'm getting error answer from API can someone help me to find fault in my code?

Does the PHP curl work?

It is not what the baseline documentation is asking for.
The documentation asks for this post data:

array (
  'method' => 'getOrders',
  'parameters' => '{"date_from": 1407341754}',
)

Your PHP curl request post data:

'array (
  'method' => 'getOrders',
  'parameters' => '{
    "date_confirmed_from": 1407341754,
    "get_unconfirmed_orders": false
}',
)'

The documentation asks
parameters = arguments of the requested function in JSON format.
Your parameters are an array, not JSON.

Okay I find out solution for this problem:

import UIKit

let url = URL(string: "https://api.baselinker.com/connector.php")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
request.setValue("application/x-www-form-urlencoded",forHTTPHeaderField: "Accept")
request.setValue("xxx",forHTTPHeaderField: "X-BLToken")

let data: Data = "method=getOrders&parameters={\"date_confirmed_from\": 1407341754&\"get_unconfirmed_orders\":false}".data(using: .utf8)!
    request.httpBody = data
    let session = URLSession(configuration: .default)
    let task = session.dataTask(with: request) { (data, response, error) in
        if let error = error {
            print(error)
        }
        if  let data = data {
            let dataString = String(data: data, encoding: .utf8)
            print(dataString!)
        }
    }
    task.resume()

The biggest problem was coding of data. curl in PHP by default sending data as x-www-form-urlencoded
