I have a protected workbook. Customer buys an activation token [includes a license] by placing an order through the WooCommerce integration kit. When the license expires, XLSPadlock should deactivate the associated order from the WooCommerce site. It does not (for me at least).
As a second mechanism, the workbook relies on a bult-in VBA which lets the customer issue a Deactivate request. The XLSPadlock API runs and does not throw an error. Still it does not deactivate the associated order. Result = customer can enter the same activation token, effectively using the order again and again.
Does the VBA API for Deactivate work for you ? If so, did you need special programming around it to make it work ?
