Description (last modified by SergeyBiryukov)

If you submit file through wp curl it doesnt send boundary params for file multipart, because in class-http.php at line 174 $r['body'] array is converted to string:

$r['body'] = http_build_query( $r['body'], null, '&' );

And curl wants array to send file boundary to rest api , in that case it fails.

$headers['Content-type'] = 'multipart/form-data';   
$args['file'] = '@/pathtofile';
$request = new WP_Http;
$result = $request->request($url,$args);

Let me know if you have questions

To put it bluntly, if you want to use cURL functionalities that WP_HTTP doesn't support, you should probably be using cURL directly.

The other WP_HTTP transports do not support the cURL send-file functionality, and you can't be sure that WP_HTTP will be using cURL on all servers. The enhancement here would be to support sending files via multipart in WP_HTTP.

WP_HTTP is designed to be a abstraction layer which allows you to use any available method of connecting to a remote site.

If you want to use curl functionality, you need to use curl directly.

If someone requires it, please open a new ticket to add generic File uploading capability to WP_HTTP instead.

I'm doing it like this and it seems to work fine:

$body      = file_get_contents( $filepath );
$mime_type = '';

if ( extension_loaded( 'fileinfo' ) ) {
	$finfo = new finfo;
	$mime_type = $finfo->file( $filepath, FILEINFO_MIME );
elseif ( function_exists('mime_content_type') ) {
	$mime_type = mime_content_type( $filepath );

$args = array(
	'method'  => 'PUT',
	'headers' => array(
		'Content-Type'           => $mime_type,
		'X-HTTP-Method-Override' => 'PUT'
	'timeout' => 30,
	'body'    => $body,

$response      = wp_remote_request( $url, $args );
