    We don't accept American Express

    Asked by WaxLily on September 07, 2014 at 04:03 PM

    Hello, my client just informed me they can not American Express cards. We are integrated with Authorize.net payment wizard. How may I limit or reject Am-Ex charges? 

    Site is in maintenance mode and I'm not comfortable leaving the URL at this time, but here's a screenshot.


    Thank you in advance!!

    Follow up : I see now that if you use a sandbox Am-Ex card number, you do get an error say "

    Error during transaction
    (TESTMODE) The merchant does not accept this type of credit card. 

    Please go back and fix this

    So I believe if you wanted to customize this message you would do so through your authorize.net portal, not JotForm.


    I'm still interested to see if there's a way to at least mention somewhere in the Payment Form wizard that Am-Ex is not accepted, to avoid confusion/frustration from rejected submissions, that'd be great to know. Thanks!

    Hi There!

    You're definitely right. It has something to configure on your authorize.net account if you want to allow a new card. Here's an article from Authorize.net that might help resolve this problem.


    And here's the exact error response from Authorize.net when you cast payment using unrecognized cards.

    Response Reason Code: 17

    Response Reason Text: The merchant does not accept this type of credit card.

    Other Suggestions: The merchant was not configured to accept the credit card submitted in the transaction.

    You can use Hover Text if you want your customers to be informed or a Text field and write down a message about the card limitations so at least they are made aware and informed ahead that using Am-Ex card isn't accepted.
