    I get a "Security error Security header is not valid " when validating the Paypal

    Asked by asccombaillaux on November 08, 2014 at 04:22 PM


    In the form http://form.jotformeu.com/form/43016419622348 I want to use payal when "mode de paiement" is set to "paiement en ligne CB".

    To do so I used a specific thank you URL on condition "mode depaiement = paiement en ligne cb" which works properly as it drives me to the appropriate jotform which call for paypal.

    But when validating this form instead of calling Paypal i get the error message "

    Security error
    Security header is not valid
    I have no clue on what is happening
    Thanks for your help.

    This is an issue with your API Credentials in the Paypal Pro payment field.  Please make sure that you are entering the correct API username, password, and signature. There's a test integration button in the Payment Wizard, I would suggest clicking that one to test out if the integration is working or not.

    Here's how you can get your Paypal Pro API Credentials: https://developer.paypal.com/docs/classic/api/apiCredentials/#creating-classic-api-credentials
