Paypal express integration error

Good Day,

I have tried all the trouble shooting protocalls on your website around proper integration of paypal express and can't seem to get rid of the error, security error header invalid.  Can someone look at our form to see what is going wrong. I have re-entred the api information from our paypal account and 100% it is correct.

I have responded to your other thread about this here https://www.jotform.com/answers/1176877

Please update us on that thread instead. I will close this one.
