Answer 1

At the very least, this code has problems with the HTTP headers you want to send.

CURLOPT_HEADER , when set to true , will cause the HTTP response headers to be included in the cURL response.

To send HTTP headers, you need to use CURLOPT_HTTPHEADER and pass an array of headers.

It would look like this:

$headers = array(
    'Content-Type: application/json',
    'PayPal-Client-Metadata-Id: 10aab1a2e941462096ca8aba539784f3',
    'Authorization: Bearer A103.Ekl88t1fnvoypD1F7HZDt3X-jzmxm6rxMxW6QtI79iIJdgDaDiIO8luWS-C1D-0z.h2YAz4LujULmTjQXcPjF8_ImbV0',
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

You'll also need to call curl_setopt($ch, CURLOPT_POST, 1); to actually send a POST request.
