Show Coupon in invoice template

Hi!
With the Premium templates extension you can show the coupons used by using the {{used_coupons}} placeholder in any of the settings fields or a custom block.

For a solution for the free version, check this post: https://www.ads-software.com/support/topic/how-can-i-show-the-coupon-code-on-my-invoices/#post-7035382

Hope that helps!
