I try to try it, but I do not see any changes in my site admin after installing it / setting the API Key.
I do not have any trace of my transactions in FraudLabs Pro dashboard.
I should do something wrong.
If the plugin is activated, the "FraudLabs Pro Details" panel will be added to the order details page. A seal (safety mark FraudLabs Pro) is displayed at checkout.
The plugin checks only those orders that follow after its installation. To check previously created orders (not completed) you need to scan them by clicking on the "Screen Order" button in the "FraudLabs Pro Details" panel.
