    Getting this when testing a new form with the eWay sandbox API codes.

    Fails with the US or Australian test credit cards

    Error is generated only if I set the quantity of the product to anything but 0.

    Switching the Sandbox switch to "yes" or "no" makes no difference.

    Any suggestions?

    I have tested our EWAY sandbox account  and it seems to be working as expected.

    I was able to submit a cloned version of your form.

    Kindly make sure you're using the correct sandbox API/Password/encryption key.


    You may also contact Eway to verify if you're using the correct API.

    Hope this information helps.
