Hello IO. I went online and found a page that provides a "test" or "sandbox" credit card account that you can use to make a test payment using credit card. After entering the info (credit card # 4111 1111 1111 1111, CVV 111, Exp. date 12/21), and after clicking "Pay Now", it gave me the error message, "

  • Square Transaction Failed: INVALID_CARD

I noticed that it asks for a valid postal code, so I used one in my area: 78260. Could it be that this postal code does not match up with the "test credit card" given above? Just trying to find out if the error is on IO side or with Square. I've sent a note to Square, also, regarding this error. Thx.
