Python 无法正确发布请求

我想通过wklej API缩短链接，他们在网站上有文档，但只针对php，我不明白问题是什么.以下是他们网站上的一个请求示例:

https://wklej.to/api/url/add

$curl = curl_init();

curl_setopt_array($curl, array(
    CURLOPT_URL => "https://wklej.to/api/url/add",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 2,
    CURLOPT_TIMEOUT => 10,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_HTTPHEADER => array(
        "Authorization: Bearer HERE IS MY API KEY",
        "Content-Type: application/json",
    ),
    CURLOPT_POSTFIELDS => '{
    "url": "https:\/\/google.com",
    "custom": "google",
    "password": "mypass",
    "expiry": "2020-11-11 12:00:00",
    "type": "splash",
    "metatitle": "Not Google",
    "metadescription": "Not Google description",
    "metaimage": "https:\/\/www.mozilla.org\/media\/protocol\/img\/logos\/firefox\/browser\/og.4ad05d4125a5.png",
    "geotarget": [
        {
            "location": "Canada",
            "link": "https:\/\/google.ca"
        },
        {
            "location": "United States",
            "link": "https:\/\/google.us"
        }
    ],
    "devicetarget": [
        {
            "device": "iPhone",
            "link": "https:\/\/google.com"
        },
        {
            "device": "Android",
            "link": "https:\/\/google.com"
        }
    ],
    "languagetarget": [
        {
            "language": "en",
            "link": "https:\/\/google.com"
        },
        {
            "language": "fr",
            "link": "https:\/\/google.ca"
        }
    ],
    "parameters": [
        {
            "name": "aff",
            "value": "3"
        },
        {
            "device": "gtm_source",
            "link": "api"
        }
    ]
}',
));

$response = curl_exec($curl);

curl_close($curl);
echo $response;

我试着提出这样的请求:

r = requests.post("https://wklej.to/api/url/add", data = {"api": "HERE IS MY API KEY", "url": "https://amazon.com"})

但作为回应，我得到了这个结论:

{"error":1,"message":"A valid API key is required to use this service."}

我最近开始学习Python，想知道我做错了什么，如果我理解正确，那么我需要发送一个JSON格式的请求.顺便说一句，他们的文档指出，在请求中，您只需要为缩写程序指定一个链接和一个API密钥，其他所有内容都是可选的.

update个

现在我这样做:

headers = {
    'Authorization': 'Bearer MY_API_KEY',
    'Content-Type': 'application/json',
}

data = {"url": "https://amazon.com"}


r = requests.post("https://wklej.to/api/url/add", headers=headers, data=data)

回应是:

{"error":1,"message":"Missing required parameter: url"}

为什么它不见了？我已经在"数据"中设置了这个
