***Update: since this article was written, we have updated our WooCommerce data collection methods. We now recommend switching to the rest API from xmlrpc, which you can read about here.
Remarkety uses WordPress's xmlrpc service in order to synchronize data from the backoffice and to generate dynamic coupons if needed.
This file (xmlrpc.php) is sometimes blocked by an .htaccess file to disable access from anywhere due to security concerns. It's possible to enable access only to Remarkety by filtering based on our IP addresses.
Your .htaccess file (the one in your http root directory) might have some other changes, so please be careful when editing it.
Add the following to your .htaccess file (or modify the existing xmlrpc.php entry) in order to allow access to the xmlrpc.php file from Remarkety's IP's only (note: The IP's here may not be updated - modify based on the most recent IP's found here)
deny from all
allow from 184.108.40.206
allow from 220.127.116.11
allow from 18.104.22.168
In the allow statements, you can use domains or IP. I'm a certified linux admin.
