Hi,
There is no "serial key" in HikaSerial, there is a "serial data".
See :
www.hikashop.com/support/documentation/1...e-in-hikaserial.html
Please read the documentation for the part "What is a Serial ?".
The serial data is the serial code, the content which is generated by HikaSerial in order to have something unique.
The serial data is generated using a serial generator, like the random generator, the coupon generator, the series generator, etc.
It could also be a data you imported in the HikaSerial database, for specific content like SIM card number, special activation key for a software.
The serial does not have any special feature if you don't use the consumption system.
The serial data is just the data, after that you can use plugins to perform actions if you want the user use the serial in your website.
See the section "Serial possibilities" in the documentation page.
Regards,
