Hello,
You have two tutorials for HIkaSerial :
www.hikashop.com/support/documentation/2...serial-tutorial.html
www.hikashop.com/support/documentation/2...ticket-tutorial.html
The first one is a generic tutorial and the second one is more oriented on the generation of "e tickets".
In your case, I don't understand why you want to create HikaShop coupon code while it's a redeem code so, you could use a simple random generator and not have to create HIkaShop coupons which I don't know how your customer will use them.
Regarding the export of the "coupons", that would be a HikaShop question if you're talking about HIkaShop coupon codes.
But if you're talking about HikaSerial serials, you have an "export" button when you're in the serial listing in the backend.
You can use the pack filter in order to just export serials for a specific pack.
CF :

Finally, HikaSerial is made to generate dynamically the serials when a customer buy a product (linked with a HikaSerial pack).
So you don't have to pre-generate the serial nor to export them.
If you do want to use the "e ticket" system and be sure that a serial can be used only once ; the random generator and the consumption feature would be a good choice for you.
