    When I attempt to do the payment, it says "Client authentication failed"

    But I followed all the steps shown on - https://www.jotform.com/help/50-PayPal-Forms

    My Client ID is correct and secret is correct - they are enabled on paypal

    I have checked your JotForm and able to replicate the issue at my end. Generally, this issue occurs when the credentials used are incorrect or incorrect payment mode is selected (live or sandbox). We request you to check the credentials used on the form and change them accordingly in the payment wizard. Also, please make sure that there are no leading or trialing spaces in the credentials used.

    If you need any further assistance, please let us know. We will be happy to assist.
