Sending HTTP Post Request to site with array in Body

Question

I'm trying to make a POST request and send some values in the body of an API call. In the documentation of the API it says I need to make a POST request, using startUrls as an array with key and value.

<?php
$url = 'https://api.apify.com/v1/USERID/crawlers/CRAWLERID/execute?token=TOKENID';

$postData = array(
'startUrls' => array(array('key'=>'START', 'value'=>'https://instagram.com/instagram'))
);
$context = stream_context_create(array(
    'http' => array(
        'method' => 'POST',
        'header' => 'Content-type: application/json',
        'body' => json_encode($postData)
        )
));
$resp = file_get_contents($url, FALSE, $context);
print_r($resp); 
?>

The JSON seems to be how it should, but the script is not sending the body properly to the website.

According to the documentation, there is no body option for the HTTP context. Try content instead:

<?php
$url = "https://api.apify.com/v1/USERID/crawlers/CRAWLERID/execute?token=TOKENID";

$postData = [
    "startUrls" => [
        ["key"=>"START", "value" => "https://instagram.com/instagram"]
    ]
];

$context = stream_context_create([
    "http" => [
        "method"  => "POST",
        "header"  => "Content-type: application/json",
        "content" => json_encode($postData)
    ]
]);
$resp = file_get_contents($url, FALSE, $context);
print_r($resp);
