    creditcard with paypal pro not working (still)

    Asked by ntr on May 23, 2010 at 07:16 PM

    I have read more bugreports on this from over a month ago. Any solution coming up for this?

    Using my API details I get:

    Invalid Data
    This transaction cannot be processed.

    When using the sandbox paypal API:

    Security error
    Security header is not valid

    Can you send me the URL of the form? I do not see any form on your account that has Paypal Pro integration.

    Please do not use sandbox account. Use your real account. Sandbox account will not work.

    I am not using the sand box. Upon contacting Paypal for support, I have found that the problem is I already have a shopping cart that uses an API certificate. Apparently you can not use an API certificate and then acquire an API signature in the same account. It is one or the other only.
    So I can not use the form unless I give up the shopping cart.

    Sorry to hear that. Can you make the shopping cart use the same API credentials you would like to use for JotForm?
