// setup user name and password
$username = 'admin';
$password = 'password';

// the standard end point for posts in an initialised Curl
$process = curl_init('http://blogimport.dev/wp-json/wp/v2/posts');

// create an array of data to use, this is basic - see other examples for more complex inserts
$data = array('slug' => 'rest_insert' , 'title' => 'REST API insert' , 'content' => 'The content of our stuff', 'excerpt' => 'smaller' );
$data_string = json_encode($data);

curl_setopt($process, CURLOPT_TIMEOUT, 30);
curl_setopt($process, CURLOPT_POST, 1);
// make sure we are POSTing
curl_setopt($process, CURLOPT_CUSTOMREQUEST, "POST");
// this is the data to insert to create the post
curl_setopt($process, CURLOPT_POSTFIELDS, $data_string);

);

// process the request
$return = curl_exec($process);

curl_close($process);

// This buit is to show you on the screen what the data looks like returned and then decoded for PHP use
echo '<h2>Results</h2>';

print_r($return);

echo '<h2>Decoded</h2>';

$result = json_decode($return, true);

print_r($result);

Anyone know of a snippet that does this using auth cookies instead of basic auth?

Use the simple jwt-auth plugin, but use this fork https://github.com/jonathan-dejong/simple-jwt-authentication/wiki/Documentation

does not work for https site

Worked for me. As is. On an HTTPS site.

Saludo, Andres.

Thanks Andrew works like magic 👍

This the one of the few examples on the web to show how to actually interact with WordPress rest api with PHP and curl :)

If you add also the fields categories, tags, meta and featured_media it becomes PERFECT!
