Hi Joost
I’ve just opened a ticket on your service desk.
Hi Joost, I’ve now tried all of your suggestion but I cannot get the Zettle to sync back to WooCommerce. When a product changes in WooCommerce the Zettle updates it’s self but if I make a sale on the Zettle or change any product details like price of quantity, the changes don’t appear in WooCommerce. I’ve tried turning off all plugins apart from Woo and Zettle and also a different theme. I’ve also check with our hosting partners and they have confirmed they do not block any requests toward the xmlrpc.php file. The server’s firewall and security mechanisms are not blocking any type of requests or hooks. There are no Mod_Security rules being triggered.
Thanks
