I have a Gatsby site andrewhudson.me which is a static Server Side Rendered (SSR) site built using React and hosted on Netlify. I wanted to trigger a build when I published a new post (or updated an existing one) in WordPress and here’s how I did it.

  1. Get webhook url from Netlify
  2. In WordPress code:
function ah_webhook_netlify_post() {
	$url = 'https://api.netlify.com/build_hooks/XXXXXXXXXXX';	
	
	$args =	array(
		'method' => 'POST',
		'timeout' => 5,
		'blocking' => false,
        );
	wp_remote_post( $url, $args );
}
add_action( 'publish_post', 'ah_webhook_netlify_post' );
