Insert Orders with API

Please answer faster if you know the answer. Give me a document or give me a clue on how I can do this.

Because my chief does not give me several days for an issue. I am very grateful for your attention.

Hi, I used your document.Thank you for your quick response
I wrote a simple class to insert the address according to the document.

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;

class XentralController extends Controller

{

public function testSoapApiXentral()

{

  $hash = $this->generateHash();

  $xml = "<name>Emilia Gruber</name>

  <strasse>Musterstrasse</strasse>

  <hausnummer>21</hausnummer>

  <plz>11111</plz>

  <ort>Musterort</ort>

  <email>emiliagruber@musterort.de</email>

  <kundennummer>NEW</kundennummer>";

  $output_xml = $this->SendRequest("AdresseCreate",$xml,$hash);

  $obj = simplexml_load_string($output_xml);

  echo "<pre>";
  print_r($obj);
  echo "</pre>";

  dd($output_xml);
}



function SendRequest($methodname,$xml,$hash)

{

// dd($hash);

  $url = 'http://xentralmain.local/index.php? 
  module=api&action='.$methodname.'&hash='.$hash.'&api_id=1';

  $xml = '<?xml version="1.0" encoding="UTF-8"?>

  <request>

  <status>

  <function>'.$methodname.'</function>

  </status>

  <xml>'.$xml.'</xml>

  </request>';

  $data = array('xml' => $xml, 'md5sum' => md5($xml));

  $options = array(

  'http' => array(

  'header' => "Content-type: application/x-www-form-urlencoded\r\n",

  'method' => 'POST',

  'content' => http_build_query($data),

  ),

);


 $context = stream_context_create($options);

 $result = file_get_contents($url, false, $context);

 return $result;

}

public function generateHash()

 {

    $initKey = '06e7134e2cb7e35f3181ad7d44894b76e74b782f';

    $remoteDomain = 'http://xentralmain';

    $date = gmdate('dmY');

    $hash = "";

    for($i = 0; $i <= 200; $i++)

    $hash = sha1($hash . $initKey . $remoteDomain . $date);

    return $hash;

 }

}

In the generateHash method, I used the Aktueller Key: value for the $initKey variable

Now I have an error for the hash. How should I fix it?
