PayPal Pro: getting an Invalid configuration error

How do I connect my paypal to my jot forms to accept payment?

Error:  invalid configuration, this transaction can not be processed, the merchants account is not able to process transactions.

I checked your form and it seems that you've connected the PayPal Pro correctly. However, I would request you to cross check the API credentials too.

Please also note that this error usually occurs when your billing agreement in PayPal is disabled/inactive or you have not agreed to the billing agreement. This PayPal error code link explains the error that is shown. 

You might consider contacting PayPal Support to get the assistance in this case.
