Hi,
You should access to the plugin option thanks to HikaSerial menu.
(menu) HikaSerial | System > (submenu) Plugins. Then "Attach Serials Plugin".
You do not require the webservice access. It's an advance feature for software licences systems.
You should create:
- a "coupon generator" configuration (in "HikaSerial > Plugins")
- a pack for your gift certificates with your coupon generator configuration.
- assign the pack to your hikashop products.
Then, every time a customer would buy the products where pack are assigned, a serial would be generated thanks the coupon generator and attached to the order (when the status of the order would be confirmed).
The email would contains the serials and if you have configured "Attache Serial plugin" the attachments would be added.
Finally, your customers won't have to do something special. Just buy a product.
