Hi,
You can simply create a paypal in sandbox mode ; with a test account.
And you can limit the payment method (be careful, not the Joomla plugin) to a specific Joomla user group thanks to the ACL (HikaShop Business).
Also, I have no notifications about Paypal payments or order details on e-mail. That is my main instrument of tracking orders, so it is very important to work properly.
It's like noone ordered and payed nothing.
If you are talking about an Hikashop email, you should receive at least 1 email when your order is created and 1 when your order is confirmed :
- Order status notification
- Order creation notification
If not, you should check if these emails are enabled via "Hikashop->System->Emails".
Also, if you are talking about a "PayPal email" you should maybe check your PayPal account or directly ask it to PayPal.
Regards,
