I'm trying to set up and test the Stripe HQ plugin but having difficulty with it so far.
I have configured the callback and redirect urls as detailed in the "Other Notes" tab.
When I place a test order with the test-accepted credit card number I am always returned to WooCommerce with a message saying that the transaction has been declined by my bank.
If I go into my merchant area and click "Fire LPN" it returns:
...which looks to me like a problem because I don't think it's supposed to be empty. Nothing happens on the WooCommerce site and the test order remains marked as "failed".
What can I do to get this up and running properly?
