Hi there Edward,
Thanks for reaching out to us on this!
I’m sorry to say I won’t be able to help much on this issue as it’s involves a third party plugin we cannot support. Please send me a link to the plugin documentation (I found a couple with pretty similar names) and I’ll take a look to see if there’s a shortcode or something useful to include the voucher fields.
Although I’m not familiarized with the plugin, I don’t think this integration could be super straight forward. From what I see you need to place these fields for each product / voucher which will make things a bit more complicated when integrating that with tickets.
Please let me know about it,
Best,
Nico
