Ich versuche Shopware Api über Postman aufzurufen,leider erfolglos

  • Ich habe den

    • shopware version 6.4.11.1
    • Access-key-id : Idxxxxxxxxxxxxxxxx
    • access-key-secret : Keyxxxxxxxxxxx

  • Im Postman habe ich
    * base url : https://my-shopware-seite.de/api/oauth/token
    * request POST
    * Authorization api-key gewählt und
    api-key : access-key-id (Idxxxxxxxxxxxxxxxxxxxxxxx)
    value: access-key-secret (Keyxxxxxxxxxxxxxxxxxxxxxx)
    angegen.
    Es klappt nicht . Mache ich überhaupt richtig? Wenn nicht, könnt Ihr bitte schreiben wie es geht?
    vielen Dank im Voraus.

I also tried with xml request it did not work.

<html>
<head>
	<title> testing </title>
</head>
<body>
<script> 
const data = JSON.stringify({
  "client_id": "administration",
  "grant_type": "password",
  "scopes": "write",
  "username": "my-username",
  "password": "my-password"
});

const xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function () {
  if (this.readyState === this.DONE) {
    console.log(this.responseText);
  }
});

xhr.open("POST", "https://my-shopware-site.de/api/auth/token");
xhr.setRequestHeader("Content-Type", "application/json");
xhr.setRequestHeader("Accept", "application/json");
xhr.send(data);
//console.log("test");
</script>

const options = {
  method: 'POST',
  headers: {'Content-Type': 'application/json', Accept: 'application/json'},
  body: '{"client_id":"administration","grant_type":"password","scopes":"write","username":"your.username@shopware.com","password":"your.password@123"}'
};

fetch('http://localhost/api/auth/token', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));
