I'm looking for guidance on the Instant Payment Notification. I'm using power.io and they're saying don't add a web address but Paypal requires one. Any guidance would be helpful. When my clients complete the paypal payment, they're supposed to receive and email notification through the power.io app on the website https://www.homeofpotential.org/copy-of-get-started. Power.io isn't getting the notification from paypal that the payment was complete, then triggering the email in power.io.
