Card payments

Accept card payments through Lynq Checkout after configuring your Ameriabank VPOS credentials.
1

Request VPOS credentials from Ameriabank

Contact Ameriabank and request VPOS credentials for your merchant account.
2

Open Card settings

In Dashboard → Payment methods → Card, select the test or live environment.
3

Enter and enable credentials

Enter the Terminal ID, username, and password supplied by Ameriabank. Save the connection, then enable Card payments.
4

Test the complete flow

Create a Payment Intent using keys from that same environment, complete Checkout, and confirm webhook delivery.

​
Checkout behaviour

Card details remain inside the hosted Checkout iframe; your page does not handle raw card numbers or security codes. Checkout handles any required customer authentication internally.

​
Test and live setup

Test and live connections are independent. The secret key, publishable key, Payment Intent, Card connection, and webhook endpoint must belong to the same environment. Return to Dashboard → Payment methods → Card to replace credentials, disable the method, or enable it again.
