Do I need to do anything to change Paypal integration?

Oops, never mind, I see someone else already asked the same question so I deleted this post.  But I do hope JotForm can answer it for us!!  Thank you very much.

No need to worry, our servers are updated with the latest security certificates that are using SHA-256 algorithm. This update that is to be implemented by PayPal will not affect JotForm's integrations, so you do not have to be concerned. Your PayPal-integrated forms will normally as expected.
