I am trying to login but it keep on giving me error code 400. Not sure why? Below is my code
Also in header I am not sure what to set as MAC IP as I don't hold mac and in client local ip I am adding my system local IP and in client public ip I am adding my server ip where my website is located.
I hope i am doing it right..

$headers = array('Content-Type: application/json', 'Accept: application/json', 'X-UserType: USER', 'X-SourceID: WEB', 'X-ClientLocalIP: 182.69.96.96', 'X-ClientPublicIP: 185.28.21.157', 'X-MACAddress: MYMACIP', 'X-PrivateKey: MYPRIVATEKEY');

    $data["clientcode"] = "MYCLIENTCODE";
    $data["password"] = "PASSWORD";

    $url = 'https://apiconnect.angelbroking.com/rest/auth/angelbroking/user/v1/loginByPassword';

    $jsonData = json_encode($data);

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_POST, 1);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    curl_setopt($curl, CURLOPT_HEADEROPT, CURLHEADER_UNIFIED);
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        
    $result = curl_exec($curl);
    $http_status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

    echo '<br/>Response Status : ' . $http_status;
    echo '<br/>Response String : ' . $result;

    //To Convert json response to array
    $resJsonArray = json_decode($result, true);

Response I am receiving is

Response Status : 400
Response String :

Hey
I am using smart API in the PHP platform
Everything is okay but I am a little lost to identify which API should I call to get the live trading data of NFO (Only for NFO)
There is not much written in the documentation.
Can you help me?
May be it is something related to LTP but I am not sure how to call it through PHP

Thank you in advance!

@admin
Thank you for the response.
Yes I am going through this documentation and I have done exactly what API asks from me but eventually I am not getting any response and getting response from API "1" nothing else

I am having login issues. In output I keep on receiving "1" and nothing else. I am not sure if I am doing anything wrong or I need to call API in different method. I have tried using below API via postman and receiving "1" as output. Further details are mentioned below.

API - https://apiconnect.angelbroking.com/rest/auth/angelbroking/user/v1/loginByPassword

Headers I am sending

1. Content-Type = application/json
2. Accept = application/json
3. X-PrivateKey = My API key

In post I am sending

1. clientcode - MY CLIENT CODE
2. password - My Password

Please help me I am stuck
