Viva.com | Smart Checkout extends WooCommerce by providing a seamless and secure payment gateway. Accept online payments with a modern checkout experience, and multiple payment methods.
Webhook security relies on allowlisting Viva.com’s published source IP addresses at your server or firewall level. If your hosting environment, WAF, or security plugin blocks Viva.com’s outbound notifications, order statuses will not be updated and payments may appear stuck.
Before going live, make sure your infrastructure allows inbound traffic from the IPs published by Viva.com. The current list and instructions are maintained at:
developer.viva.com — Whitelist the Viva addresses
This requirement is independent of the plugin — it applies at the server/firewall layer and must be configured by your hosting provider or system administrator.
