Hi,
Thanks for the report.
It looks like I forgot to removed some options in the interface part of the plugin.
1/ Can you check with just " {hikaserial_genpack:1} "
HikaSerial will load the configuration of your pack with the id " 1 ". Using this configuration, it will use the associated generator to create a new serial in the database and return it to Acymailing.
If there is no generator or the generator does not generate any serial (some require to access to an order and the plugin can't provide it) an empty content will be returned to Acymailing.
We would need more details about the pack 1 and about the generator which is used with this pack.
2/ To get the billing or shipping address, you need an order. Only the order know what is the billing and what is the shipping.
It could be possible to insert the default user address but we will need to update the AcyMailing-HikaShop plugin only support product insertion for the moment.
Kind regards,
