Akamai Bypass (Java)

I am writing a bot to auto purchase items on a website (zalando). Everything goes well from login to adding items to shopping cart but at the very end it doesn't work anyomore. It sends this error: { "edge_error": "halt", "ref_id": "18.57c51102.1663765843.299fc0e", "wait": 60, "feedback": { "email": true, "url": "", "recaptcha": { "enabled": false, "type": 0, "sitekey": "" } }}

I think it has something to do with their protection or just me missing a header or cookie or a delay... I honestly have no clue anymore This is the code I use in the end (to checkout and generate a paypal link (post response)):

public void makePostJsonRequest(WebDriver driver, String eTag, String checkoutID)
{
    retrieveCookiesMap(driver);
    HttpClient httpClient = new DefaultHttpClient();
    try {
        HttpPost postRequest = new HttpPost("https://www.zalando.be/api/checkout/buy-now");
        postRequest.setHeader("authority", "www.zalando.be");
