One way to do this is like this:
- Create a simple script on your website.
- Have the script take the product key and a data you want to store in custom fields (like parent program version).
- Save the data to the custom license field for the product key using these functions: http://wyday.com/limelm/help/api/limelm.pkey.getID/, http://wyday.com/limelm/help/api/limelm.pkey.setDetails/
- From your plugin simply call the script on your website passing the product key (TurboActivate.GetPKey() ) and whatever other data you want to store in the custom fields.
