    I have followed your guide on how to set up the form. (REST method, Client ID and Client secret...).


    the error message on Paypal Checkout button press is:


    Payment error: Client authentication failed


    please help

    Generally, our users encounter the same issue when the Client ID or Client secret is incorrect. Please check these fields. You can try to re-create an app and get the new Client ID and Client secret fields.
