After a long search, I found this post:
WooCommerce hook for "after payment complete" actions
which talks about creating web hooks in WooCommerce t
with the help from @helgatheviking and @Scriptonomy I settled on this code, with NO webhook enabled in woocommerce->settings->api->webhooks:
add_action( 'woocommerce_payment_complete', 'so_payment_complete' );
function so_payment_complete( $order_id ){
$order = wc_get_order( $order_id );
$billingEmail = $order->billing_email;
$products = $order->get_items();
foreach($products as $prod){
$items[$prod['product_id']] = $prod['name'];
}
$url = 'http://requestb.in/15gbo981';
// post to the request somehow
wp_remote_post( $url, array(
'method' => 'POST',
'timeout' => 45,
'redirection' => 5,
'httpversion' => '1.0',
'blocking' => true,
'headers' => array(),
'body' => array( 'billingemail' => $billingEmail, 'items' => $items ),
'cookies' => array()
)
);
Now I just have to write the listener :) This is the body of the request that gets sent (which I can see at requestb.in):
billingemail=%22aaron-buyer%40thirdoptionmusic.com%22&items%5B78%5D=Cult+Of+Nice&items%5B126%5D=Still&items%5B125%5D=The+Monkey+Set
