Make payment in php to RAPYD COLLECT

Am trying to make payments to a wallets using Rapyd Collect in php following the 2 sample code below but it print null Value as result

https://docs.rapyd.net/build-with-rapyd/reference/payment-object

sample code 1;


<?php


$path = $_SERVER['DOCUMENT_ROOT'];
$path .= "/payments/utilities.php";
include($path);
$body = [
    'receipt_email' => 'johndow@rapyd.net',
     "amount"=> 100,
    "currency"=> "USD",
    "description"=> "Payment by card token",
    "payment_method"=> "card_823894ee89c52be00e76d2be10116672",
    "complete_payment_url"=> "http://localhost/success.php",
  "ewallets"=> [
            "ewallet"=> "ewalletmy-ewallet-id-goes-here",
            "percentage"=> 100
        
    ],

     "address"=> [
        "name"=> 'John Doe',
        "line_1"=> '123 Main Street',
        "line_2"=> 'Penthouse',
        "line_3"=> '',
        "city"=> 'Anytown',
        "district"=> '',
        "canton"=> '',
        "state"=> 'NY',
        "country"=> 'US',
        "zip"=> '12345',
        "phone_number"=> '16125551234'
      ]
];

try {
    $object = make_request('post', '/v1/payments/payment_19e3edad1e9102cd24006a34c52c9a0b', $body);
    var_dump($object);
} catch(Exception $e) {
    echo "Error: $e";
}

exit();

?>

I think the problem is value for payment_19e3edad1e9102cd24006a34c52c9a0b or card_823894ee89c52be00e76d2be10116672.

What are they. how can I solve the issue
