<?php

//put in your nation slug and token
$url ="https://<your slug>.nationbuilder.com/api/v1/people?access_token=<token>";

$data = array(
    'person' => array(
    'email' => "[email protected]",
    'last_name' => "Bob",
    'first_name' => "Smith",
    'sex' => "M",
    'employer' => "Dexter Labs",
  ),
);

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($ch, CURLOPT_TIMEOUT, '10'); 
curl_setopt($ch, CURLOPT_HTTPHEADER, 

array("Content-Type: application/json","Accept: application/json"));

$json_data = json_encode($data);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);

$json_response = curl_exec($ch);
curl_close($ch);

$response = json_decode($json_response, true);

print_r($response);

?>

You might need to add curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); to your cURL options for this example to work in some environments.

Thanks for the example!
