We have been using Clover iframe SDK.
When we try with doing payment for declined card : 4005 5717 0222 2222
As per https://docs.clover.com/docs/test-card-numbers#section-simulating-declines it should decline transaction. But it goes through and I am getting success and payment is processed.
Similarly when I am trying with below two cards which should be allowed, but instead I am getting "card number is invalid".
