When I testing on the sandbox environment with paypal button it's work OK But on production I always getting response INVALID. My code is very similar to the googlecloudfunctions.js example Thanks

The most common cause seems to be plus signs in dates and email addresses due to decoding issue which can cause these problems. This is a community member provided code sample which is harder for us to support; however, if you provide the value of formUrlEncodedBody we can take a look as well.

@elile Try changing your encoding to UTF-8 in your account profile IPN settings to see if that resolves the issue. If that toggle does not resolve your issue then reach out the PayPal Technical Support for assistance at https://www.paypal-techsupport.com/app/ask, due to the sensitive nature of production information.
